Fibre Optic Cabling in Business

Fibre Optic Cabling in Business

The Role of Fibre Optic Cabling in Business

Fibre optic cabling systems are becoming increasingly important in modern business. Communication, after all, is crucial when it comes to operating a business. Business needs information to be transmitted and received in several ways. And it has to be fast. We live in fast-paced times and anything below par is going to hinder you competitively. Fibre optic systems are vital for success and you need to know more about them.

What does Fibre Optic Cabling do?

Fibre optic systems use cabling which is similar to electrical cable. But there’s an important difference: fibre optic cabling uses fibres to carry light. This light can be transmitted over large distances, easily over 100km if necessary, and makes it perfect in communication systems. Optical fibres are generally housed within glass cladding, the glass helping to reflect back any light that escapes the core.

What are the 2 types of fibre optic cables?

It’s important to understand the difference between single mode and multimode fibre

two main forms of fibre cabling:

  • Single Mode: The core size of single mode fibre cables is very thin and this is where its innovation lies. Thanks to the thin core, light signals can travel directly through the core without the risk of bouncing off the internal sides of the cable. This significantly reduces the amount of light reflection created during transmission. The signal benefits from a sustained quality and, as a result, is able to travel successfully over long distances. Single mode cables are typically used to power the internet and telephone applications. 
  • Multimode: The size difference, when it comes to the cable core, is noticeably larger in multimode cables. In fact, the diameter can be up to ten times larger than single mode cables. Greater light gathering capacity is the main benefit from this difference. This allows light to travel along a number of different paths within a cable. Whilst these cables can only transmit signals over short distances they are perfect for connecting internal computer networks.

What is Fibre to the Desk?

You may have heard the phrase Fibre to the Desk mentioned before, but you’re only going to know what that means if you’re a communications professional. Thankfully it’s a simple concept. Fibre to the Desk is a cabling structure which directly connects end users to fibre cabling. This is notably different to Fibre to the Office which involves local conversion from fibre to copper cabling to connect users. Fibre to the Desk gives increased bandwidth and high speeds and is considered a superior solution due to its simplicity.

How Can You Test Fibre Optic ?

Fibre optic cables, as with any form of technology, are prone to wear and tear along with failures. Being able to test these cables is essential in maintaining them. The best way for testing the integrity of fibre cabling is through an Optical Time Domain Reflectometer – OTDR testing. The OTDR is able to compose a comprehensive picture of the state of fibre cables. It can be used to analyse splice loss, find faults and accurately measure lengths.  Performance or structural problems of your cabling system can then be identified and rectified.

What is data cabling used for?

Data Cabling and Why Business Needs It

There was a time when data cabling was only of interest to high tech companies. But it’s no longer the limited preserve of these companies. Thanks to advances in technology and falling prices, network cabling is now easily affordable for even the smallest businesses. And this is good news as it has the potential to take your business to the next level. It does this by simultaneously enhancing your productivity and maximizing your competitiveness.

What is Data Cabling?

We’re all aware of what cables are, but cabling for data is a little different. And cabling in office, commercial, warehouse and education settings is incredibly important to their operation. Accordingly, data cable installations are of interest to virtually every business. But what is it?

In its simplest definition, data or network cabling involves multiple devices within an IT network being connected by cables. This IT cabling comes in a number of categories such as CAT5e, CAT6 and fibre options. Typical data cabling installations will run from a specific device to a central communication cabinet to help facilitate the flow of data.

Cat5e, Cat6 or Cat6a cables, which are made from copper, can run at speeds of up to 1000 and 10,000Mbps respectively, but only over distances of 100m. Fibre cables, meanwhile, are also capable of speeds of up to 10,000Mbps, but this can be maintained over distances of up to 500m – 2Km. Copper cables, therefore, are suitable for shorter distances and fibre gives you more flexibility over longer distances.

How Your Business Uses Data Cabling

Data cable or Structured Cabling can provide a crucial boost to your business by being used in the following ways:

  • Connectivity: The most obvious benefit of data cables is that they can connect multiple devices to a central infrastructure. This allows information to flow seamlessly and quickly from point A to B. Almost every device within your business from photocopiers through to network servers should be able to benefit from data cabling. 
  • Data Cabinet Relocations: Structured cabling solutions are perfect when it comes to relocating data cabinets. IT cabling has, traditionally, consisted of many different types of cabling and this has contributed to complex setups. But the simplicity of modern cabling ensures that data cabinet relocation can be completed quickly and with the minimum of fuss. 
  • Enhancing Competitiveness: Modern data cable solutions have allowed businesses to become more competitive. For example, the rise in popularity of Voice over Internet Protocol (VoIP) has allowed telecommunications to use just one data for telephone and internet connections. This maximizes not just space, but also the efficiency of your IT setup. And, in turn, this allows you to push your IT systems and grow your business. 
  • Bolster Scalability: The use of structured cabling allows businesses the opportunity for scalability. Data cable installations, therefore, ensures that your IT and telecommunication systems have room for growth and, given the compatibility of different data cables, allows your systems to remain future proof.

With  Cat5e, Cat6 or Cat6a cabling now available to every business it makes sense to implement it within your infrastructure. Perfect for any form of IT setup, data cabling can future proof your technology and deliver results that will boost your productivity.

Electrical Installations for Data Centres

Data Centre Electrical Installation

Data centres and comms rooms are crucial assets for any modern business. By installing these hubs within your company you are laying the foundations for both growth and competitiveness. Data, after all, is a key aspect of competing in the digital age. And, as anyone working in an operational data centre will tell you, there’s a lot of it.

But you need these areas of intense processing and power to be working to their full potential. To put it simply: there is no room for error. If, for example, you lose your comms room power then the majority of your business operations will stop. And this will spell disaster for your productivity and profits. Clearly, it’s important to have a reliable setup, but how do you go about achieving this?

What are Data Centres and Comms Rooms?

Before we go any further it’s a good idea that we understand exactly what these data centres and comms rooms are. The good news is that both terms are interchangeable and mean the same thing, so there’s only half the learning you were expecting. So, what is a data centre? Well, it’s simply a central location where an organization concentrates the main engine of its IT and telecommunications equipment e.g. data storage, network servers and telecommunication networks.

What Do You Need to Install a Good Data Centre?

Seeing as your data centre will be housing essential business elements, as well as needing to stick to server room standards, it needs to be installed correctly. To achieve this make sure you take the following into account:

  • Planning: The complexities of a data centre dictate that planning is critical when it comes to an installation. It’s not as simple as deciding where to position equipment and where the plug sockets need to be installed. Instead, you need to invest considerable time into understanding what your business needs and how your budget can best achieve this. It’s then a case of formulating a strategy to put this into place and give your company the best comms room it can have.

 

  • Power is King: Without power your business won’t be able to operate. Therefore, one of the most important elements of any data centre install is a reliable power supply. It not only needs to be able to cope with your demand, but it needs to do so with the minimum of problems. No power supply, however, is 100% perfect. And this is why installing emergency backup power supplies – such as a UPS and generator installation – is the surest way to maintain operations.

 

  • Scalability: A good comms room will hopefully be matched by a good business which, over time, grows. But this growth needs to be taken into consideration when designing and installing your data centre. IT and telecommunication technology is complex and far from space saving. Accordingly, your comms room needs to take this into account, so make sure there is ample space to house additional equipment, power supplies and cabling.

A world-class data centre will become the lifeblood of your organisation’s technological activities. And it will have the potential to push your business to new heights. But the intricacies involved with this technology mean it’s difficult to get right. And this is why it pays to connect with professionals who can both advise you on the best way forwards as well as delivering on these promises.

PAT TESTING PORTABLE APPLIANCE TESTING - Electrical Testing

PAT Testing in the Workplace

A Quick Guide to PAT Testing for the Workplace

Electricity is a form of energy which can be exceptionally powerful and is used extensively in workplaces. It can be used to power offices, factories and shops in a variety of ways. But electricity can also be dangerous. Any workplace, packed full of electrical products, represents a significant risk to your staff and your customers. That’s why it’s crucial that you regularly test your electrical appliances.

The most common safety test carried out is PAT testing. It’s a series of checks which safeguards people coming into your business and ensures that you meet the Electricity at Work Regulations. You may not be familiar with the methods behind PAT testing, so we’ve put together a quick guide.

What is PAT Testing?

Portable Appliance Testing (better known as PAT ) involves the examination of electrical products to verify their safety and confirm they are fit to use. The procedure takes in the following checks:

  • A visual inspection of both the cables and the appliance to identify any significant damage e.g. split cables and exposed components
  • An insulation test which measures the quality of insulation that protects any parts of the appliance which carry a current
  • Carrying out an earthing continuity test to determine whether earthing conductors are suitable enough to protect against electric shock

A PAT test can be completed relatively quickly by connecting appliances to a PAT testing device. If the appliance passes the PAT test then it can continue to be used. However, any appliance that fails its PAT test must be removed from service immediately. Although not a legal necessity, it is considered good practice to label individual devices with a PASS/FAIL sticker.

Electrical Testing in the Workplace

The Electricity at Work Regulations state that all electrical systems must be maintained in order to prevent any form of danger. The regulations do not specifically indicate that PAT testing itself is a legal requirement, but the fact remains that it’s a crucial step in maintaining appliances. PAT testing is a guaranteed method for evaluating the safety of electrical appliances. As such, it should form a part of every organisation’s maintenance routine.

When it comes to PAT testing frequency it is recommended that these checks are carried out as per below:

  • Offices, Hotels and Shops: Electrical appliances that fall under the class 1 category – stationary and IT devices – should be tested every four years. However the recommended time between tests is much shorter for portable equipment (every two years) and handheld equipment (every year) 
  • Public Use: Stationary equipment, along with IT systems, should be tested every year if they are being used by the public. Class 2 appliances – those which do not require an earth connection – are also subject to this yearly test. However, any portable and handheld equipment that is handled by the public should be PAT tested every six months.

Final Thoughts

PAT testing is one of the simplest methods of protecting your staff and your customers. Not only does it help your business comply with the Electricity at Work Regulations, but it minimises the risk of electrical accidents. Accordingly, it’s vital that your business understands all PAT testing requirements and also adheres to the recommended PAT testing frequency periods. Most important of all is to work with competent PAT testers who can confidently certify your equipment.

Power and Lighting for Industry

Industrial Power and Lighting

Power and Lighting for Industry

When it comes to an industrial setting you need to make sure that you have the correct power and lighting in place. Without these crucial elements correctly installed, you are going to seriously struggle with your productivity. And this means that your business will be less competitive. Naturally, you want your business to be productive and competitive, so investing in the best power and lighting is of the utmost importance.

Why You Need the Right Power and Lighting

An industrial setting is both busy and dangerous, so safety is a vital factor. Power, of course, is the backbone of an industrial environment. But the methods by which power is supplied can be dangerous. Electrical cabling, for example, can cause numerous problems such as trip hazards; this is magnified in a situation where significant amounts of machinery are in use. And lighting is just as important. Industrial settings such as factories and refineries can be starved of natural light. Therefore, you need to ensure that these workplaces are lighted satisfactorily.

Modern Developments in Power and Lighting

Industrial landscapes have been part of our everyday lives for well over a century now. This is why there is such a huge industry based around supplying power and lighting solutions. But this doesn’t mean that all the relevant solutions are in place. The owners of industrial businesses may not even be aware of many of them. And, thanks to advances in technology, there is a revolution taking place in industrial power and lighting.

Some of the most exciting developments in this area include:

  • Smart Controlled Lighting Systems:

    The wonder of smart lighting has proved popular in domestic and office settings, but it has remained a stranger to industrial settings. However, this scenario is slowly changing. Wireless technology combined with powerful interfaces has opened up endless possibilities in the industrial sector. The systems are simple to install and allow you to customise your lighting needs with precision.

  • Under Floor Power:

    Industrial settings are busy workplaces and this calls for significant investment in health and safety measures. And one of the quickest and most direct ways to address this is with under floor power. Electrical equipment, of course, needs to be connected with cabling. But this cabling, aside from being unsightly, is also dangerous in an industrial environment. Under floor power addresses this by allowing you to run all cabling underneath walkways and work areas.

  • Temporary Lighting:

    Alternative solutions to lighting are always important to have; temporary lighting acts as not just a backup, but also a fantastic solution for working at night. Temporary lighting uses multiple lights that all connect to one power supply. It’s a solution which provides you with a portable lighting option that is perfect for any works taking place outdoors. It can also, if required, be implemented internally in case of any lighting failures.

 The Perfect Solution

It’s essential that businesses in the industrial market work with the best power and lighting solutions. Falling behind here will blunt your competitive edge and have a major impact on the safety of your workplace. However, industrial power and lighting systems are complex. And, due to the potential hazards of working with electricity, it is highly recommended that you team up with professionals. This will guarantee that your setup sticks to the relevant regulations and will be completed on time.

Electrical Installation Surveys During Covid-19

How can I get an electrical installation survey done during lockdown?

With the new guidelines on social distancing and the message to stay at home, conducting an electrical installation survey is becoming increasingly difficult or not possible to carry out in person.

However this time shall pass and those projects that need to be completed will still need to be undertaken. A delay in survey will lead to lag in quotation, approval and the project being mobilised and undertaken.

The aim now is to reduce that time lag by still carrying out the earlier part of the process using innovative techniques and systems to complete these surveys and quotations allowing clients to put these budgets into their cash flow so when social distancing is reduced these works can happen immediately.

How can surveys be completed without coming to my place of business?

The majority of surveys can still be undertaken “off site” and the more information that can be collated during this process the more accurate the quotation will be for the needs of the client.

The majority of the information doesn’t change whether it’s a meeting on site or an off-site discussion. The numbers of cables required, the number of users moving into a building, the requirement of the electrical installations, the timescales to complete these works.

Also the construction of the space can easily be communicated which with the knowledge of the project management team accurate quotations can be built. For example, does the space have a false ceiling, a false floor, is there dado trunking around the walls of the offices, how long and wide is the space and where is the electrical cabinet in relation to those requirements?

Drawings allow the process to be even more accurate and will show our quotation team a visual of the space to gauge distances, routes and requirements.

The final element which then allows a 99% accurate quotation is the provision of photos and videos. With the information above and photos or videos of the proposed requirements our team is confident that the quotation provided offsite will be as accurate as an on site survey.

If someone is still based at their offices or place of business a simple walk through the building with Facetime, Zoom or Whatsapp will allow our team to provide the quotations you need.

What Project Surveys And Quotations Can Be Undertaken Off Site?

The majority of projects can be quoted accurately off site and are especially suited to the following due to the similar nature of the spaces:

  1. Offices
  2. Warehouses
  3. Data Cabinet tidy ups and re-patching
  4. Audio Visual Installations and Video Conferencing
  5. Schools
  6. New office space where estimates are required (moving to new offices)
  7. Data Centres
What project surveys and quotations are not suitable be undertaken off site?

The following projects usually involve some deeper understanding of the requirements and survey of the spaces and even though these projects are not best suited to off-site surveys than can still be quoted with a quotation range as a budget which can then be confirmed with an on-site meeting once the opportunity arises.

  1. Listed building and building with restricted electrical installation routes / drilling

Due to the complicated routes and limitations on what can be changed, drilled and have containment fixed, an on-site survey is usually best for these buildings.

  1. Residential Homes

Homes by their nature have no obvious routes for electrical installations, so seeing the building internally from the start to end point is important. These projects are best suited to an on-site presence.

  1. External electrical installations and fibre optic links between buildings.

Using technology such as Google earth can assist in proving quotations for these works but in a population dense area such as London the routes externally between buildings or spaces sometimes follow many changes of direction and elevation which cannot be seen or understood off site.

The advantages of Projects during social distancing

With the ability to still provide quotations during the social distancing stage we can then follow through with structured cabling installations during the shutdown of many offices, schools and places of business.

The advantages are that the work can be completed win a much safer way as the premises are empty, the works can be completed in regular hours rather than incurring an out of hours installation cost and in some cases the works can be completed quicker and more economical as the absence of employees in the space allow the works to be completed faster.

Accuracy and Guarantee

The more information that is able to be communicated the more accurate the quotation can be for the client. However in 20 years of pricing so many different projects we know from experience that over 95% of projects we have quoted in the past from off-site information have resulted in no changes to the price, once an onsite meeting has followed to firm up requirements, and of the 5% that have had the change the price hasn’t deviated by more than 10%, once further information was known.

Therefore, during these challenging times if we provide an off-site electrical installation quotation for you based on the information received during a conference call and with the required supporting information we will honour that set price if the on-site follow up doesn’t change the pricing by more than 10%. In essence it allows the cost to increase by 10% and we will still complete the works at the originally supplied quotation

For those quotations that can’t be accurately quoted a range of budget pricing can be supplied and firmed up on site once the situation allows to still enable the clients to budget in their cash flow.

Call us to book an electrical installation survey or a quotation, or simply to talk through your current project.

Coronavirus - Impact on Technology and Electrical Installations

Covid 19, Coronavirus and the Impact on Technology and Electrical Installations

Coronavirus and the Impact on the Technology and Electrical Installation Industry. A Truthful assessment of what’s coming.

The impact of the coronavirus on the world as a whole, as we have all seen, has been massive and a large proportion of industries will be affected; technology and Electrical Installation will be no different.

Many of our clients have been asking us what effect this means on currently planned in work and upcoming proposed projects.

Below is our honest opinion on how this will affect the electrical  industry and where it can be incorporated into your companies industry.

The Impact on Installations, Essential Works and Safety

The complications with the current coronavirus is that no one knows how long it will continue, when work can return back to normal or even a small resemblance on what was previously normal.

Companies are concerned that having installers in their offices during these times risk exposure and spread of the virus and as a company we wholeheartedly agree that for the world as a whole we need to practice social distancing, and this starts with the eliminating or reduction of installations where exposure to other employees, trades or workers is non manageable.

This then leads on to what’s essential and therefore able to be scheduled.

Each company’s definition of essential will vary based on requirements, the infrastructure of the business and the overall impact that the delay in those structured cabling works will have on the operation of that business.

As a company we have seen essential works having to be completed for UK essential businesses such as Royal Mail, Banking and Finance where installation that were mid project were required to be completed unless the overall operation of those deliveries would be affected.

However, in a contrasting manner we have seen many projects be delayed or cancelled due to the lack of essential requirements. Projects have also been rescheduled where health and safety can’t be guaranteed for the end client or the installation companies involved.

The impact on Surveys, Meetings and Quotations

The biggest impact on the industry so far has been the reduction and almost elimination of meetings, surveys and the knock on affect to quotations and proposals for Electrical Installations.

With many staff now working from home there is now a lack of presence within all the companies and buildings that would be arranging installation surveys or design meetings.

(Especially in the London area where public transport is massively reduced and seen as a medium to avoid where possible.)

The effect on the industry is: Reduced surveys leads to reduced structured cabling quotations and reduced installation projects.

The effect overall is a positive for battling the virus as each reduced element increases the social distancing.

Opportunities, Smarter Working and Solutions

This period of upheaval will pass although no one knows how long and how definitive that timescale will be. Once the initial rise starts to flatten and more is known on how to manage the virus, the distancing and how people will start to return to work then focus will return to how all those projects that have been delayed can start to put into place.

This will apply for all industries, not only the technology and electrical industry.

The opportunity here is to plan in advance and undertake those surveys, processed the quotations and schedule the works in anticipation of the return to a somewhat normal working week.

As a company we are undertaking increased surveys offsite with a detailed almost interview like discussion over the telephone or video conferencing. In those situations where employees are still based within their offices, photos, videos and live streams are being used to survey these works and enabling detailed and accurate quotations to be supplied.

Also, where quotations are accepted and works agreed on as essential and safe to install, engineers are able to attend almost empty buildings and undertake these works in a safer manner than was ever possible.

Not only are the social distancing elements upheld but a larger proportion of health and safety measures are now massively minimised or eliminated. Health and Safety concerns such as removing false floors in an active office, working on ladders around employees and especially noise pollution within an office or heard in other company offices.

Summary

Is the upcoming period going to be difficult and an upheaval? The answer of course will be based on what your company does and how the virus plays out.

However what we do know is at this time we have more technology and ways of filling voids than we have ever had before and these can be used to bring an element of normality back to the survey, quotation and installation process within the Electrical Installation industry.

So while others stand still waiting to see what happens, allow us to use these opportunities to actually increase the effectiveness and completion times of those important projects and leave the rest of the precious time to getting back to normal within your business.

Smoke Alarm Regulations picture of smoke detector

Smoke Alarm Regulations

Smoke and Carbon Monoxide Alarm Regulations

It goes without saying that inhaling smoke and carbon dioxide is incredibly harmful for the body. Smoke has the potential to inflame your airways and cause respiratory failure. And carbon monoxide poisoning can also cause severe damage to the body. High levels of carbon monoxide reduce the amount of oxygen in the bloodstream which in turn, stops oxygen reaching tissues and vital organs. The end result can eventually be brain damage, heart failure and even death.

Thankfully, smoke and carbon monoxide alarms are available to protect you from these risks. However, it’s crucial that you and your alarms comply with the regulations.

What are the Key Smoke and Carbon Monoxide Regulations?

The Smoke and Carbon Monoxide Regulations were introduced in 2015 to improve fire safety and protect homes in the private rented sector. The main regulations that you need to be aware of are the following:

  • A smoke alarm needs to be installed on every storey of the premises that are either fully or partly used as living accommodation.
  • Carbon monoxide alarms must be installed in any room which is used, in any way, as living accommodation or contains an appliance that uses solid fuel burning combustion.
  • Smoke and carbon monoxide alarms need to be tested and confirmed as being in good working order when a tenancy commences.
  • Although not a legal obligation, it is recommended that landlords conduct regular testing to confirm that smoke and carbon monoxide alarms are in good working order.

All of these regulations are logical and sensible steps that can make a significant difference to the safety of all properties. But how do you make sure you comply with them?

How to Comply with the Regulations

It’s down to private landlords to install smoke and carbon monoxide alarms in their rented properties, so they need to take the initiative to comply with the legislation. If you’re a landlord then you need to take note of the following:

  • It’s important to understand what constitutes a storey used as a living accommodation. A bathroom may not feel like a living accommodation, but the Smoke and Carbon Monoxide Alarm Regulations classes it as one. Meanwhile, a floor of a property which is purely used for access is not classed as a living accommodation and does not need an alarm.
  • There is no obligation to install a specific type of smoke or carbon dioxide alarm. As long as the alarm is in good working order and capable of detecting threats then it will comply with the existing regulations.
  • All alarms need to be installed and operating from day one of any new tenancy. Therefore, to avoid hefty fines, it is recommended that checking the status or existing alarms (or installing new ones) should be one of the earliest steps to take when renting a property.
  • Once a tenant moves in it is down to the tenant to regularly test the alarms with a recommendation of once a month. However, it is recommended that private landlords also take the initiative to test the alarms in order to maximise safety and guarantee peace of mind.

Smoke and Carbon Monoxide Alarm Legislation UK

By following the regulations to the letter, private landlords can rest safe in the knowledge that they will be providing properties which are safe for tenants. See the current Smoke and Carbon Monoxide Alarm (England) Regulations here

RCD residual current device

What is an RCD?

What is an RCD and How Does it Work?

 

RCDs, or residual current devices

A residual current device (RCD) is one of the best ways to protect yourself from electrical equipment. Accidents, after all, can happen. And the dangers of electricity mean that the consequences of these accidents can be severe and even fatal. By installing RCDs into your electrical systems you can significantly reduce the risk of electric shock.

Understanding what an RCD is and how it works could make a real difference to the safety of your electrical equipment, so let’s take a closer look at RCDs.

How Do RCDs Work?

An RCD is a safety device which is able to detect faults in electrical supplies and immediately switch the circuit off. This prevents the flow of electricity and provides protection against electric shocks. For example, a sudden surge of electricity will cause the RCD to trip out and shut down the current. As mentioned earlier, this reduces the risk of electric shock, but it also prevents the risk of electrical fires developing from faulty equipment.

Types of RCD

There are more than one type of RCD and the most common ones you will encounter are:

  • Fixed : Typically found within a fuse box, a fixed RCD delivers the best protection against electric shocks. A fixed RCD is capable or protecting individual circuits and more complex setups which are comprised of multiple circuits. This type of RCD is, given its fixed position, constantly providing protection to your circuits.

 

  • Portable : As the name suggests, a portable RCD can be moved to wherever it’s required. A portable RCD is most commonly used when your options are limited for installing an RCD such as on a construction site. The portable RCD simply plugs into an available socket outlet and is then ready to have an electrical device plugged into it.

 

  • Socket Outlet RCD: Replacing a standard socket outlet, a socket outlet RCD provides a much safer option for working with electrical devices. They are commonly found in extension cables and used for outdoor appliances such as lawnmowers.

What would trip an RCD?

An RCD is considered a highly reliable device and will prevent electrical shocks in around 97% of all cases. Naturally, this is a success rate which is highly favourable to your well-being, but it is not a 100% guarantee. Therefore, you should always be careful when working with electrical applications and RCDs by following these best practices:

  • Test Your RCDs
    All RCDs will have a test button built into them so that you can test that they are working and will disconnect the circuit. You should run a test on each RCD every three months to confirm that they are in good working order. If the test button does not activate the trip then contact an electrician to investigate this further.
  •  Check Your Wiring
    It’s important that any electrical installations (and the RCDs themselves) are checked every 10 years. Wiring can deteriorate over time and circuits can easily malfunction, so it’s crucial that you cover every base rather than relying on the promise of an RCD alone.
For more information on RCDs and the options available to you, don’t hesitate to get in touch with one of our expert engineers.

How much do led lights save?

LED Bulbs: How Much Can You Save?

How-Efficient-are-LED-Lights-We’re well aware of the benefits that LED bulbs come packed with. Not only do they have long lifespans, but they also produce unrivalled levels of brightness and embrace energy efficiency. The beauty of all these benefits is that they combine to deliver a lighting solution which is high performance and cost effective.

But how do LED Bulb costs compare to those of traditional lighting methods?

How Efficient are LED Lights?

The traditional method of lighting for homes has always centred around incandescent light bulbs. But advancements in technology have led to the emergence of LED bulbs as the new kings of lighting. Many people initially shied away from upgrading to LED bulbs. Change is always a difficult concept to get to grips with and many consumers have stuck to what they know. Especially when they see the price of LED bulbs. But that initial price tag can be misleading.

Do LED lights really save you money?

There’s no escaping the fact that LED bulbs cost more than traditional lighting methods. An 8W LED bulb, for example, costs around £3.50. Its incandescent equivalent – which would be rated at 60W – will cost just £1.50. That’s an 80% price difference. And that would appear to be significant. But it’s not as clear cut as the initial expense being the deciding factor.

LED bulbs, you see, have a wide range of benefits. And these benefits far outweigh those offered by traditional incandescent bulbs. Let’s take a closer look at how these benefits can lead to long term savings:

  • Lifespan: An LED bulb should be expected to last for 50,000 hours. This gives you value for money in the long term when you consider that an incandescent bulb will only last for 1,000 hours. Therefore, one LED bulb will last as long as 50 incandescent bulbs. Using our 8W/60W comparison, that equates to a saving of £71.50 over the course of the LED bulb’s life. 
  • Energy Costs: One of the main areas where LED bulbs thrive is their energy efficiency. An LED bulb will always use a smaller wattage compared to an incandescent bulb. And this means that less energy is required to power the LED bulb. Less energy equals less cost.
