Reasons for Electrical Testing

Electrical Testing should always be carried out by qualified electrical professionals. There are two types of electrical testing ‘Dead’ and ‘Live’.
Dead testing are tests that are carried out when there is no electrical energy running; it is done to measure the resistance of the circuits.
Live testing is performed once the dead testing is complete and has been passed and the installation has been put back together following the dead testing.

There are seven different types of testing, three ‘dead’ tests and four ‘live’ tests.

The dead tests are in order of
Ring Circuit Loop Impedance – this ensures that any ring circuits wired in the installation are in the shape of a ring and not a figure of eight loops.
Circuit Loop Impedance – ensures that any circuit wired in the installation are containing the cables that conduct one end of the cable to the other.
Insulation Resistance – checks the insulation of the cable has not been damaged and has no faults present.
The live tests are in order of
Polarity Testing – ensure apparatus connected to the circuit is connected correctly.
Earth Loop Impedance Test – to check the resistance of the earth cable is not too high as to prevent it from working correctly in the event of a fault.
Prospective Short Circuit Test – this is to ensure that in the event of a short circuit the fuse will blow and cut off the circuit.
Residual Current Device Test – the final test is to make sure the residual current devices will trip fast enough to prevent electrocution in the case of a fault.

How to Cope When Your Boiler Breaks Down

A boiler breakdown can not only be inconvenient and costly, it can also pose serious risks to your health, especially for those who are vulnerable. However, there are measures you can take to prepare for a boiler breakdown situation and to cope with one should it ever happen to you. Here’s what to do if your boiler breaks down.

1. Contact a Qualified Engineer

In the event of a boiler breakdown, the first thing you need to do is to contact a GasSafe qualified engineer. Your engineer will inspect the boiler, identify the issue and resolve to fix it as soon as possible. The amount of time it takes to solve the problem may vary depending on the complexity of the issue. In the meantime, you can use the following guidelines to stay warm and healthy.

2. Conserve Heat

While you are waiting for your boiler to be fixed, it important that you do everything you can to stay warm. Ways to do this include dressing in extra layers of clothing, keeping your curtains closed, using draught excluders and preparing warming meals like soup. Remember to keep your doors closed and to use sources of heating only in the rooms you are using. This way you can keep your energy bills in check.

3. Stock Up, Just In Case

As a preparatory measure, you should stock up on hot water bottles, blankets and alternative sources of heating.

4. Ask Friends and Family For Help

Reaching out and asking for help from neighbours, friends and family will give you much needed moral and practical support. You can always offer to return the favour but most of the time, people in your local community will be happy to provide assistance in your hour of need.

How to Choose the Right Electrician

Choosing a great electrician is not as difficult as you might think. With some general pointers to keep in mind, this article will help you choose the right electrician for you.

Look for an Electrician in Your Local Area

There will be plenty of great local electricians that you can look for in your area. Take a look in newspapers and local directories. Otherwise, you could also track one down online, which will save you time and hassle. Always specify your location in your search. For example, if you are looking for an electrician in Cambridge, type in “domestic electrician in Cambridge” and you will see only the most relevant results.

Find One that is Recommended

Ask your friends and family to recommend an electrician they have been happy with in the past. This is a great way to make sure your electrician of choice will provide you with great customer service, just like they did with your friends and family!

Check the Internet

Check the internet for reviews and forums related to your electrician of choice. A word of warning, however, basing your choice on one review is never a good idea. Always try to look at the overall picture and bear in mind that reviews can be biased. Nevertheless, reviews are a good way of gauging whether you would be getting the outcome you desire and if you would be truly happy parting with your hard-earned cash.

Speak to Them

If you’ve got an electrician in mind, give them a quick call to find out what services they offer and at what price. This way you can get a better idea of the kind of service to expect. A phone call of this nature can also help you to make up your mind fairly quickly.

Check Their Qualifications

Reputable electricians will hold qualifications that prove their expertise. Always ask to see their certification and identification as a rule. This is especially important if you are vulnerable or are hiring anyone on behalf of someone who is.

The only way you will truly get to know whether you have chosen the most competent and professional electrician is to give their service a try.

Why Go Through With a Boiler Installation?

There are many benefits to having a new boiler installed. Take the time to carefully choose the right boiler for you.

  • Greater energy efficiency

As your boiler is responsible for 60% of your annual energy bill, having a new boiler installed can significantly improve overall energy efficiency. This is better for the environment and can help reduce your carbon footprint.

  • Save Yourself Money

Once you have a new boiler fitted, you will see a significant reduction in your energy bills. This is because a more efficient boiler means less energy is required to function. The less energy needed to operate the boiler, the less money you will have to pay towards your annual energy bills.

  • Increased Reliability

Newer boilers provide increased reliability. The result of this is that you will be less likely to have to shell out on boiler repairs or inconvenient breakdowns. The event of a boiler breakdown can be extremely difficult to deal with, especially since we rely on heating and hot water, particularly in the winter.

  • Safer

Modern boilers are far safer and less risky than their older counterparts. Carbon monoxide poisoning is a potentially deadly occurrence that claims many lives each year. Modern boilers are thoroughly safety checked and, providing you seek out a qualified boiler installation technician, your new boiler will be safer for you and your family.

  • Maximises on space

Certain modern boiler models take up less space than older boilers. Furthermore, you can have your new boiler relocated to a more suitable area in the house. Your engineer can help advise you on your individual needs.

Lux Electrical offer reliable and quality boiler installation and repair. Our engineers are all registered as GAS Safe (formerly Corgi), meaning you can be safe in the knowledge that your boiler installation in Cambridge will go as smoothly as possible. The cost of a boiler installation can vary, so to get an accurate quotation, contact Lux Electrical today.

3 Things You Need to Know When Thinking of Rewiring Your Property

If you are considering having your property electrically rewired, there are several factors you may wish to keep in mind. Below are five things to consider.

  • Older Properties & Renovation Projects.

Before you even buy your home, you need to consider whether you can budget for a rewiring project. If the property you are interested in acquiring is older than 25 years, you will need to consider having your property rewired seriously.

Older properties with old wiring can pose a serious fire risk as faults can quickly develop. Renovation projects are time-consuming and expensive, but it is essential that the electric wiring powering the building has not been compromised by age.

  • When is Rewiring Necessary?

Upgrading the wiring in part or in full in your property is essential if your property is older than 25 years. This is because the current system may not be able to cope with modern requirements as it may not comply with current standards.

Furthermore, if you are planning remodelling or extension work, such as a garage or an attic, your existing wiring and fuse box will need updating and/or rewiring completely.

  • Finding an Electrician to Carry Out the Work.

With rewiring projects, it is highly advisable for you to seek out the services of a fully qualified and reputable electrician. It is possible to carry out the work yourself without having to apply for a Building Regulations Application for smaller electrical projects such as installing a new socket or light fitting, providing it is not in a wet area like a bathroom or kitchen. For any larger projects or electrical work in wet areas, you will need a Building Regulations Application and the expertise of a qualified and experienced electrician who will carry out appropriate testing.

Our Electricians are fully qualified and have a wealth of expertise in all aspects of domestic electrical services.

5 Things to Consider When Planning a Kitchen or Bathroom Renovation

1. Budget

Work within your budget and compromise where needed in order to stick to it.  In all likelihood there is a high possibility that you will have to incur unexpected costs, everything from unplanned structural works to having to shell out for extra materials means that costs can rise quickly.  Take the time to visit showrooms for inspiration and shop around before you commit to anything. This also ensures you are able to pick out the best deals and maximise how far your budget can stretch.

2. Realistic

Be realistic throughout the process, particularly when it comes to the design of your kitchen or bathroom. There will be instances where the colour of worktops you set your mind on is out of stock, or you have to rethink your budget when it comes to labour and materials. Furthermore, you will have to bear in mind design and functionality to suit the space you are working with. If you have a small room that couldn’t possibly fit a huge freestanding roll-top bath then perhaps one that is corner fitting would be more suitable.

3. A Good Contractor

Recommendations from friends and family go a long way in ensuring you know what to expect from your kitchen or bathroom installation. If the contractor you choose comes recommended, works efficiently and is easy to deal with, you will have a much better experience. Make sure they are fully insured and that they are willing to clarify payment and work schedules with you. Check references and communicate your needs to them. Enquire about keeping to one area, so dirt and detritus will not get tracked throughout the house.

4. Timescale

It may take longer than expected to complete the project you have in mind. It is very important to communicate your needs with your contractor. Chances are they will be more than happy to negotiate a realistic timescale that suits both parties and stick to it!

5. Access

Access to your kitchen and bathroom will be limited whilst work is being carried out, so you may need to use the facilities of friends and family. Alternatively, you may have to adapt to the situation for an extended period of time, so be prepared to stick with it for the long haul, at least until your beautiful kitchen or bathroom is completed.
If you are looking for a kitchen or bathroom installation or renovation, contact Lux Electrical to discuss your design options.

Materials of Light

Have you ever wondered about the materials that weave beautiful, pure light itself? Here we explore the spectrum of extreme elements that give off light across the many beautiful types of lighting.


Incandescent Lights


Bright lights are the traditional light bulbs most often used throughout the home and general purposes. Most incandescent lights today use tungsten as the element of the filament – the filament being the part at the heart of the bulb that gives releases light as a result of heating up as it resists the electricity. Tungsten is affordable as well as long-lasting with excellent flexibility and a very high melting point, making it a smart and economical choice for general light bulbs. In the past, however, before tungsten was discovered as widely available for use, however, precious platinum was used instead, which could sustain a brilliant white light.


Fluorescent Lights


The inside surfaces of fluorescent light tubes are often phosphor-lined, and they contain exotic elements such as neon, argon, xenon, and krypton, as well as low-pressure mercury vapour. Neon and argon are extracted from liquid air, and the latter, amazingly, is entirely unreactive to electrical charges of any strength. The purpose of the mercury vapour is to enable the sparking of UV energy, and we can see the light given off by the other elements after this UV energy bounces off the phosphor coating. Neon lights contain not only neon but other elements like hydrogen, helium, and mercury, to produce different colours.


Halogen Lights


Halogen lights offer a very real brilliance, and so are the lights often used in spotlights and downlights. As well as containing tungsten filaments as do incandescent lights, halogen bulbs contain other elements including fluorine, chlorine, bromine and iodine which fall under the halogen group of elements.


Metal Halide Lights


Metal halide lights are used for durable, heavy duty, and often outdoor and roadway light purposes. Street lights owe their light to the presence of sodium. Other outdoor lights contain the halogen elements such as discussed above but mixed with other, metallic elements, forms metal halides. The resulting light is very powerful.


Arc Lights


Arc lights, those used for studio lighting or as projector lights, owes their stage-worthy brilliance to the rare earth elements lanthanum and cerium, cerium increasing light intensity by ten times when mixed with oxides and fluorides. Lanthanum is invaluable to the treatment of people with chronic kidney problems, and cerium’s particular use is that it helps precious metals like platinum to remove pollutants.

New Years Lights

The Most Spectacular New Year’s Lighting Projects

Light has always been the favourite universal way to express the excitement in anticipation of the New Year, for light represents hope, joy, prosperity and rich fruitfulness for the future, around the world. Here are some of the most sophisticated and splendid light shows that warm thousands of hearts and produce fireworks in the soul.

Indigo Fountains of Stars

Japan is truly dedicated to the spirit of New Year, which is reflected in their light shows. For example, the Shidome Caretta Illumination, which begins in early November and doesn’t end until almost mid-January, creates a world of dreamy, ultraviolet indigo, richly scattered with 24,000 cool silver and lilac toned LED lights. It is like being surrounded by magical midnight fountains pouring with all the stars in the galaxy and is seemingly bathed in a halo of moonlight. A heart-touching aspect of the New Year’s celebrations in Japan is that every year in Kobe town, it holds an impressive light show to commemorate the Great Hanshin earthquake of 1995.

River of Light

The New Year’s light shows of Medellin, Columbia, is particularly excellent for its emphasis on river themes by the Medellin River. It combines the spectacular light of the New Year with the continuous beautiful flow of the scenic river. Romantically, the New Year’s celebrations here begin on the Day of the Little Candles on 7th December. It features 3D luminous, colourful water creatures on the land, and large ornaments hung up on the trees. The colours and patterns of the light shows here are designed to work with the incredible waves of the crystal river.

Pineapple Paradise 

Saint Augustine in Florida holds an exotic ‘Night of Lights’ show. It’s a lush display of tropically golden light against fields and trees of delicious green. The fruity hues are utterly reminiscent of fun, scrumptious pineapples and the scene is one of pure paradise. It is natural yet luxurious; a completely indulgent and gorgeous place to be at New Years.

Garden of Gold

Copenhagen’s Tivoli Gardens are bountiful on beautiful light shows during New Year’s celebrations. In addition to Christmas trees, the existing vegetation becomes gold-spun with lights; the whole garden encapsulated in precious magic. Gazing at this garden is enough to enchant the heart.  Meanwhile, the Christmas light show at Tivoli Lake throws otherworldly rainbow fountains dancing over the water, leaping joyfully through all the different wavelengths of the spectrum.

Galaxy Shower

The Ayala Triangle Gardens in the Philippines is blessed with a natural treasure of beautiful and diverse trees. These are used to full advantage for New Year’s when countless threads of endless little lights are hung from high up on the many foreign branches. Among an overarching scheme of cosmic blues and purples is a range of other colours, reminding one of the iridescent flecks of abalone shells and mother-of-pearls.  Exploring these extensive gardens at this time of year is like a floating through a galaxy that showers you with an infinite pour of stars.

The Gift Of Light

The Gift of Light

Light is one of the most beautiful gifts of electricity, and with such an incredible variety available for all areas of your home and purposes, you never need to be lacking the right light in your life. Here are a few of the most beautiful styles:

Glowing Pendants

Pendant lights hang elegantly from above by a single cord and give a soft, pretty glow. They are able to emit a gentler, lunar radiance from their globes or bowls as their bulbs are installed in groups, so that the light that is shared between them gives a more muted effect. The atmosphere created is delicate, refreshing, and romantic.

Enlightened Walls

Wall sconces are lights that are fixated to the walls, and most give the appearance of a soft glow pouring out the top, bottom, or both open parts of the sconce. These glowing pockets punctuating the walls creates a mystical, almost sacred feel. Other wall sconces come in traditional light forms including candle styles, lanterns, and wallchieres. These give a beautifully classic appearance that reminds one of the old libraries and wonderful palaces.

Trail of Light

Light in patterns that follow a particular trail or pathway includes track lighting and stairwell lights. Track lighting is where spotlight-style light fixtures are attached throughout conductive tracks across the ceiling. These give a showy, glamorous feel that works well in accent lighting for drawing attentional to sophisticated works of art. Stairwell lights, on the other hand, have more of a timeless, fairytale charm. They can be fixed on the stairwell in a variety of ways and make the staircase look like an enchanted path moonward.  


Uplighters are lights that are fixed in a way that the illumination is directed upwards from within the bowl. The effect is very heavenly and the appearance is one of true preciousness. Uplighters create an inspiring and uplifting feel with their skywards direction and ethereal softness.

Stars Shining Down

Downlights are small lights that are fixed into the ceiling in numbers. Their radiance is concentrated to their spot and shines down steadily. They are most often circular and are like looking up at great stars in your home. They are luxurious, dreamy, and just like the lights, you find in aeroplanes when you’re high above the clouds.

Washed with Light

Types of lighting that give the majestic appearance of parts of the room being washed with lights include cove lighting and soffit lighting. Cove lighting is where whole blocks or strips of light are placed up on shelves or ceilings. The light echoes off the surrounding surfaces and the resulting softened effect across whole areas or edges give an overall look that is radiant and refreshing. Soffit lights are lights fixed up on the walls in multiples that shine down, turned inwards, giving the appearance of fluid, dreamy light pouring down, reminding one of the moonbeams and creating a slumbersome feel that makes it perfect for evenings.
