IEE Wiring Regulations consider electrical installations in the bathroom to be a “special location” due to water increasing the risk of electric shock. Therefore anyone responsible for bathroom electrics should adhere stricly to BS7671 the ‘Requirements for Electrical Installations’ , which gives clear instructions relating to ‘Locations containing a bath or shower’. Also, if at any point you are unsure on installing your bathroom electrics seek advice from our professional London electricians.
Bathroom wiring can include lights/downlights, extractor fan, mirror power, shaving socket, switches etc. . Read more about bathroom wiring
Does your consumer unit has a RCD?
A residual current device (or 'RCD') will detect an earth leakage and isolate a circuit in milliseconds, before an accident can occur. You can check if your RCD is working properly by pressing its test button.
Is your consumer unit too old?
If your consumer unit cover gets cracked or broken, ensure that you replace it straight away. In older houses, you sometimes find a mixture of old fuse boxes attached to the fuse board beside the electricity meter. These can be dangerous, and we'd strongly advise you to replace it with the new one.
Consumer unit or the fuse box, is very important and the main part of your installation system in the house. It is there to distribute power according to your installation need and design, and more importantly to protect you and your house from fire or electrocution. The BS7671 regulation now requires that all installations in the house to be RCD protected, and the latest amendment requires the fusebox to be of metal closure.
Whether it is a garage mini -fuse - box, or you want to replace your old one, please ask for a quote here.
Installing or fitting an electric cooker must be done on its own circuit. An electric cooker cannot be spurred of any other circuit and must be controlled by its own fuse at the consumer unit. For this reason, if this is a new installation it counts as installing a new circuit and is forbidden by any other than a Part P qualified electrician.
Electric cookers draw huge amounts of current because of the heat they need to produce so a larger fuse is required as is thicker cable and a double pole isolating switch. Usually when a switch is installed it interrupts the live wire of the circuit. The switch breaks the connection in the live wire. An Isolator is a heavy duty double pole switch disconnecting the live and the neutral is broken so there is no fear of any residual current causing a shock when the switch is off.
Dimmer switches allow you to control the brightness of a light. This is achieved by regulating the amount of current flowing through the circuit.
The most basic, and consequently, the least expensive variety of switch, is the simple dial that you turn to click on, and turn further to make the light brighter. Obviously the reverse is true to dim and turn off. You can of course change the traditional rock switch to a dimmer switch. Tell us what plate finish you want and what type of light/bulbs you have or intend to use and we will be there for you. Please ask for a quote here..
You might want to get rid of your old pendant light and replace it with nice looking downlights. This is a bit tricky as it need more cabling pulled around the room ceiling, considering the decorated and carpeted spaces. But this is something we do time to time and manage to complete the fitting with little disturbance on the floor or ceiling.
Poorly installed downlighters are the cause of a significant number of fires in homes every year.
Large showers use a lot of power (load), and this can cause issues on older installations that may have consumer units that are not capable of handling this extra load, so before you even decide you want an electric shower, you should check your fuse board and the size of the supply coming in to your property.
Kitchen electrical work It is essential that you get your kitchen electrics right when designing your kitchen
Hire a professional electrician from London Electrical Installation to install your kitchen electrics
If you are building a new house or just re-doing your kitchen it would be sensible to make sure spend time and money on the electrical work, because this is not a job you will want to revisit afterwards. When planning kitchen electrics there are three main things you will want to consider: the 13 amp socket circuit (for kitchen appliances), the 30 amp supply for high load appliances (such as electric cookers) and the lighting circuits. You must ensure that all three are carefully considered and meticulously planned so the end result is an easy to use kitchen.
It’s not usually hard to find out whether your house needs electrical rewiring. First of all, if fuses blow regularly, sockets overheat or do not work at all or other irregularities appear when you use electric devices, there is probably something wrong with the electrical wiring. If the wiring has not been replaced for 50 years or if the cables look worn, it is not advisable to wait until something goes wrong – electrical rewiring should be carried out as soon as possible by a qualified electrician. If the fuse box and the electrical wires are in good condition but you have only one or two sockets per room, it may also be a good idea to have an electrician install some additional sockets to avoid overloading the existing ones.
Why choose electric under floor heating?
Heating your house from underneath the floor means you can enjoy constant warmth in your rooms without having to unduly raise the air temperature. Conventional radiator systems create air currents with the heat first rising to ceiling level before descending towards the floor. This often makes the head feel hot and stuffy while the feet remain cold. Electric and under floor heating systems achieve a greater feeling of warmth at a lower air temperature as they typically only need to heat the floor to between 22 & 26°C, gently warming the whole floor and the room occupants from the ground up. See illustrations below
Lighting can determine the entire look and feel of any environment. Within your home you may want to employ differing lighting settings at varying times. Study areas and kitchen worktops could benefit from effective task lighting, while living areas are more suited to relaxing lighting.
Well thought out lighting design can improve not only the look of your home, but also the way you feel when you are in your home. London Electrical Installations can provide a complete design and installation on domestic or commercial properties access London.

The benefits of using London Electrical Installations
What is a Testing and Inspection?
An inspection and series of tests to make sure your electrical installation will continue to conform to the national safety standard. A Testing and Inspection will reveal if any of your electrical circuits or equipment are overloaded. Find any potential electric shock risks or fire hazards. Identify any defective electrical work. Highlight any lack of earthing or bonding.
Tests are also carried out on wiring and fixed electrical equipment to check that it is safe. A schedule of circuits will also be provided, which is invaluable for a property.
Why is a Testing and Inspection needed?
Electrics deteriorate with use and age - and electricity can be deadly. So it’s vital that people are’t put at risk.
How often is a Testing and Inspection required?
Your electrics should be tested every:
Other instances when a Testing and Inspection should be carried out are
When a property is being prepared to be let.
Before selling a property or when buying a previously occupied property.
Who should do it and what happens?
. The inspection should meet BS 7671 – Requirements for Electrical Installations (IEE Wiring Regulations). That’s the technical name for the 850 regulations that are checked in this test.
Electrical Faults Are a Safety Hazard
Electrical faults are a health and safety hazard and could be putting your life in danger. Whether in the home or work environment, electrical faults put people at risk of electrocution and electrical fire. London Electrical Installations electricians are highly skilled in the practice of electrical fault finding and will locate your fault quickly and with minimal disruption to your routine.
Problems must be solved by replacing only defective equipment or components in the least amount of time. One of the most important factors in doing this, is the approach used. An expert troubleshooter uses a system or approach that allows them to logically and systematically analyze a circuit and determine exactly what is wrong.
If any of the list below happens often, it will need investigating
Loss of Supply ?
A fuse tripped in the plug?
Fuse tripped in the fuse box?
Flickering lights or electrical appliances that come on intermittently?
We are currently looking after electrical sustainibility in a number of properties around London. If you are a Landlord and want to have a piece of mind regarding electricity in your properties please send us a line and we will be happy to discuss your needs.

You might want to have other TV boxes around the house and in your rooms. Just with one aerial cable you can split and amplify the freeview signal and watch TV channels for free. Give us a call and you are on the way.....
Freeview is a Digital TV service that allows you to watch over 40 TV channels via your TV aerial. No dish required, no subscription, no ties, no contracts, and no installation costs.
If you have other digital signal in the house you can:
Connect your Sky box to a second TV with high-quality co-ax aerial cable, or.
Connect your Sky box to a second TV with a wireless video sender, or.
Get an extra Sky box for the second TV set
Sky Digital: If you want a second Sky box, you’ll be wanting Sky Multiroom. This gives you a box in each room, each one cabled to your satellite dish. You will need a Multiroom subscription for each additional box
For this option to work, your set-top box must have an RF aerial output socket (to accept a plug like the one pictured). Also, the set-top box must have something called a modulated output (which means it can re-transmit a signal to a second TV set). Boxes from Sky Digital, Virgin Media and BT Vision (grey models) have these, as do some Freeview boxes
Virgin Media: You will need a second V BoxBT Vision: You can’t have two BT Vision boxes connected to broadband at the same time, so getting a second BT Vision box won’t do you many favours. As BT Vision gets its live TV from Freeview, a second Freeview box may be all you need.

View on your iPhone/iPad – We can set your CCTV System to be viewed on your Smart Phone – Many of the systems are compatible with Smart Phones. If you’d like to view your CCTV footage through your phone, let us know to discuss it further.
Closed Circuit Television systems are broadly divided into two known types:wired CCTV systems and wireless CCTV systems
Wired CCTV Systems
Wired CCTV systems connect the camera to the recording device and monitor with the help of standard coaxial cables or Unshielded Twisted Pair (UTP) cables or fiber optic cables.
The key advantages of wired CCTV systems are:
Provides the best picture quality with zero interference.
The camera can be located hundreds of meters away from the recording or monitoring equipment.
All sensors can be run from a single power supply
The key disadvantages are:
Cabling and installing can be a tedious task, requiring help from experts
Observation is fixed to a specific area and the camera cannot be easily moved to another location.
Overall, wireless cameras are relatively more expensive than traditional wired cameras. Wireless CCTV systems are a preferred choice in specific locations devoid of easy cabling facilities and for individuals requiring an easy-to-install solution. The wired CCTV system is a preferred choice when good picture quality and economy considerations gain precedence.
Wireless CCTV systems
Wireless CCTV systems are increasingly becoming a popular choice among CCTV buyers on account of the ease of installing such a system, lack of cabling requirements and assured mobility.
The key advantages are:
A wireless camera can be moved to other locations requiring observation while it is difficult to move a wired camera.
Best suited for locations requiring temporary observation or in a temporary location.
Wireless camera can be hidden to detect theft or pilferage
Wireless recording and monitoring device need not be in the same line of sight allowing observation of any place from another remote location.
Wireless systems are cost effective, re-deployable and portable.
At the same time, there are some disadvantages of wireless CCTV systems, which are listed below.
There are a wide variety of CCTV cameras suited to different purposes and budgets. Make sure that you take the following into account when choosing:
Camera form and function? The first thing is to decide where and how you want to position a camera and what you want sufficient coverage of. The most common types are a fixed bullet or dome camera, suitable for both indoor & outdoor use (weatherproof) with discreet styling. Other cameras provide more advanced functions such as remote pan/tilt/zoom control while smaller hidden cameras are suited to catching thieves indoors.
Analogue or Network IP camera? Analogue cameras have been around for years and are now very affordable. The main difference when it comes to performance is that IP cameras are capable of providing an image with greater detail (Mega pixel IP cameras). However with increased resolution is increased cost and for small business/home use if you require a multi-camera system that is suitable for indoors & outdoors with night vision, then an analogue system will offer sufficient monitoring and recording capabilities at a very affordable price.
If you require only a single camera to monitor/record through your local PC network (router) or wish to monitor multiple locations via the internet then this is where IP cameras can be more cost effective as they do not require a DVR to do this.
CCD/CMOS sensor & resolution? A camera with a CCD sensor generally produces a better image with a higher resolution. Analogue camera resolution is measured in TV Lines (TVL). 420TVL and above is ideal with 600TVL being about the most you can benefit from with a standard monitor. 420TVL equates to about 500 x 582 pixels. Pixels is the digital resolution measurement used with IP cameras. Lens, viewing angle and vari-focal cameras: The lens determines the viewing angle and zoom of the camera. Typical fixed lens cameras provide around a 50 degree viewing angle, however wider angle options are available which are a little more 'zoomed out'.
A vari-focal camera provides an adjustable lens enabling you to perfectly alter the angle, zoom and focus on install
Colour/Black & White? Nearly all cameras provide a full colour image and revert to black and white for low light/infrared viewing
Night time viewing with infra red? Many cameras come equipped with a ring of infra red LEDs enabling black and white viewing in complete darkness. Night vision capabilities vary as some cameras are able to see much further than others, ranging from 5m to 50m
Audio? If you require audio capabilities, certain models do come with an integrated microphone. However a separate/discreet microphone is often used.
Wired/Wireless? Wireless cameras provide a quick and easy solution without the signal wires. The problem with analogue wireless though is the susceptibility to interference. However newer models are now interference free (such as the Swann ADW range) although the image quality is not too good and suitable for general observation and low risk applications only. More expensive wireless IP cameras are the only way to achieve good quality interference free wireless CCTV coverage.
You're less likely to become a victim of burglary if you have a well-fitted and maintained burglar alarm system,
Intruder Alarms, Burglar Alarms, House Alarms, Security Alarms… Whatever you wish to call them, our alarm systems will enable you to have the peace of mind you and your family need.
The best type of alarm for your home depends on your personal preferences, your budget, where you live, what your home is like and what level of protection you need. A key consideration is what you would prefer to happen when your alarm goes off. Bells-only alarms make a noise, but don't contact anyone (such as the police or the homeowner). A speech dialer system meanwhile, automatically contacts you or other nominated friends and family when the alarm is triggered.
Hard wired alarm systems are generally considered more robust, reliable and require less maintenance. A hard wired alarm system would usually be installed by a professional to hide the cables, thus increasing the installation cost.
The installation of a hard wired alarm system should meet with British Standard 4737/BS EN 50131 and conform to the ACPO Intruder Alarm Policy. Ensure this is documented in your quotation should your chosen alarm company suggest a wired home alarm system.
You are more than twice as likely to die in a fire at home if you haven't got a smoke alarm. A smoke alarm is the easiest way to alert you to the danger of fire, giving you precious time to escape.
.How many smoke alarms do you need?
It is a recommendation by BS 5839: Pt.6: 2013 that a new build property with no more than 3 floors (less than 200sqm per floor) needs to be fitted in with a LD2 System , Grade D.
In Scotland, England and Wales. Building Regulation has recommended that BS 5839: PT6.should only be followed as a minimum. LD1 System, Grade D should be installed.
In Northern Island Building Regulations have stated that a LD2 system, Grade D should be installed. Escape routes, the kitchen and then main living room should be installed with Smoke Alarms.
The BS 5839: Pt.6. gives out grades to different alarm types to help define which alarm type is needed for a situation.LD2 refers to the number of alarms to be fitted in the property. There are three categories to domestic type protection, LD2 being one of the three. Below are Diagrams and an explanation of the three categories and how and where you would use them in a single and multi storey dwelling. LD3 is the system with the least protection and LD1 being the highest
Maintaining your smoke alarm
The different models available
A lot of people forget to check their smoke alarms, so the best choice of power supply is usually the one that lasts longest.
An ‘ionisation battery alarm’ is the cheapest and most basic smoke alarm available. An ‘optical battery alarm’ is a little more expensive. Both run off 9-volt batteries.
Battery alarms with an emergency light
These come fitted with an emergency light which comes on when the alarm is triggered. They are particularly suitable if someone in your house has hearing difficulties.
Alarms with 10-year batteries
These are slightly more expensive, but you save on the cost of replacing batteries. They are available as ionisation or optical alarms and are fitted with a long-life lithium battery or a sealed power pack that lasts for 10 years.
Models with a ‘hush’ or ‘silence’ button
Some models are available with a 'hush' button which will silence the alarm for a short time. This can be used when cooking, for example. If there is a real fire, giving off lots of smoke, the hush system is overridden and the alarm sounds. These models will continue to remind you they have been silenced by 'chirping' or by displaying a red light.
These are powered by your home’s electricity supply and need to be installed by qualified electricians. There’s no battery to check, although they are available with battery back-up in case of a power cut.
Interconnecting or linked alarms
Some alarms can be connected to each other so that when one senses smoke, all the alarms in the property sound. They are useful for people with hearing difficulties and also in larger homes.
Mains-powered alarm with strobe light and vibrating pad
These are designed for people who are deaf or have hearing difficulties. If there’s a fire, the alarm alerts you with a flashing light and vibrating pad (which is placed beneath your pillow).
Mains-powered alarm which plugs into a light socket
This type of alarm uses a rechargeable battery that charges up when the light is switched on. It lasts for 10 years and can be silenced or tested by the light switch.
Properly installed smoke detectors/alarm will detect smoke from a fire and set off an alarm that will then warn of a fire and possible save lives. There are two types of smoke alarm:
These detect all types of smoke that contain small particles, but they respond most rapidly to smoke caused by fires such as a chip pan fire.
The detector in these alarms consists a small amount of radioactive material that detects any invisible smoke particles that are floating in the air. When particles in the smoke are detected, the alarm is set off.
These detect all types of smoke, but are ideal for smoke with larger particles, such as burning furniture. In this alarm regular pulses of Ultra Violet light are sent to a detector, if the light is prevented from reaching the detector, the alarm will sound.
“All sockets must be RCD protected for safety. An RCD or residual current device works by switching off the flow of electricity when a cable or flex is cut, and should be hardwired to your fuse box. “Cables for fixed outdoor lighting installations must be buried at a sufficient depth to avoid damage from garden tools and should also be protected by an earthed metallic cover. This will require the electrician to dig a trench in the garden. Where possible lay piping or conduit for cables to pass underneath any hard landscaping. London Electrical Inspection & Testing can advise what to do if hard landscaping has already been laid. “Decorative lights plugged into an outdoor socket, should be taken inside after use unless the box states they are not designed to stay out all year round.”
