Electric shower installation in London.

Electric showers offer great benefits to households where there is a limited supply of hot water from the tank, as it provides hot water or demand – a must-have for busy families where everyone is trying to get ready at around the same time!

Electric showers completely bypass the hot water requirements of other showers as they take water from the cold water supply and contain a heated element which functions by bringing water to the required temperature as it passes through the shower unit, almost instantly heating it by the time it reaches the shower head.

The temperature is controlled by changing the rate at which the water  passes over this element. The installation of a new electric shower must be carried out by a Part P qualified electrician or plumber. Any electric shower must be supplied on its own circuit directly from your fuse box to ensure the safety of the installation.

SW Electricians are fully qualified to install electric showers and will ensure that your installation complies with the building regulations. We will provide you with the BS7671 Certificate that shows that the work has been carried out safely.

Bathroom sockets

Using or installing traditional sockets in bathrooms or shower rooms is not allowed unless they can be fitted at least three meters away from the bath or shower, which is not practical in most bathroom spaces. 

However, if you are looking to install equipment such as a bathroom television, SW Electricians  can help you to add hardwiring outside of the bathroom to allow for the use of bathroom approved appliances.

Shaving socket installation

Low voltage shaving sockets are allowed in bathrooms and are a great way to allow power not just for electric shavers, but to items such as electric toothbrushes, flossers and other low voltage bathroom equipment. 

SW Electricians can assist you with the installation of safe and effective sockets for your bathroom, taking into account the needs of your family. 

Installing a towel rail or heater

Installing a towel rail or heater

Central heating is the safest way in which to keep your bathroom warm. However, this is not practical in all cases, and many homeowners love the aesthetic and practical benefits of having a towel rail or specialist heater in their bathroom. 

Any electric or gas water heater which is installed in a bathroom must be fixed and permanently wired unless they are powered by a socket which is fitted at least three metres from a bath or shower. Under no circumstances should a portable heater ever be used in your bath or shower room.

Extractor fans installation London

Extractor Fans Installation London

Having a fully functioning extractor fan in your bathroom, shower room and toilets is essential for reasons of hygiene and to ensure that your damp rooms remain free from condensation which can lead to damp and mould.

Damp is harmful to both the structure of your property and the health of those who reside within it. 
If you are a landlord or own a commercial building, ventilation from either a bathroom window or an extractor fan is a legal requirement, and any bathroom  should have a fan which extracts  at a rate of at least 15 litres per minute and continue to run for 15 minutes after the light is switched off.

 We will work with you to put in place the best extractor fans for your bathroom requirements, connecting it safely to the electricity supply.


Extractor fan repair and replacement

If you are experiencing any of the following issues – it may be a sign that you need to repair or replace your bathroom extractor fan

  • Loud or excessive noise that was not present previously
  • A loss of power to the fan
  • The bathroom suffering from increased moisture/showing mould
  • The timer failing to work (staying on, or not coming on at all)
  • Obvious damp spots in the bathroom or shower room area

At SW Electricians we will always advise you on the best course of action and will repair your fan wherever possible.  


Can I have a television in my bathroom?

Yes! There are some televisions which are specifically designed to be fitted in bathrooms. However, due to the dangers posed by mixing water and electrics, you are required to choose a TV which is specifically designed for this purpose. 

The wiring for this type of installation sits outside of the bathroom, and at SW Electricians we have a wealth of experience in installing bathroom TV’s.

Digital wireless shower installation 

A new innovation in shower technology, digital showers offer many benefits including the ability to control temperature from outside the shower, and in the case of wireless versions, offer more flexibility around the installation.

Fed up of jumping into the shower and waiting for the water to heat up – why not get it flowing to your preferred temperature before you even step foot inside your shower enclosure! 
Thanks to the fact that they have a separate mixer and unit and shower control, the valve can be hidden so less pipework is required. 

Bathroom electrical installations

Bathroom Electrical Installations

It’s a known fact that water and electrics don’t mix. In fact, as water is a conduit for carrying electricity, the combination of the two can be fatal. Therefore is it vital that, if you require an electrical installation within your bathroom, this must be carried out by a certified electrical contractor. 

At SW Electricians, we have assisted with the installation of a wide range of electrical elements in bathrooms all across London. Our expert electricians work to the highest standards to ensure that any electrics provided in your bathroom are completely safe, while still allowing you to enjoy features such as electric showers, ambient lighting, and even a TV or speaker system.

Bathroom safety  - Electrical zones

In order to ensure the safety of any electrical installations within bathrooms, en-suites, shower rooms and wet rooms, there are wiring regulations in place which provide guidance of the design, installation, testing, and certification of them.

These regulations (BS 7671:2008 Requirements for Electrical Installations, section 701) divide the bathroom into different zones based on the electrical risk in each area. This will take into account factors such as how close they are to water, humidity and condensation, plus how likely any electrical items in the area is to get wet. 
Bathroom light fittings and installations are given an IP (Ingress Protection) rating which is matched to the zones for which they are suited. 
Here we explain the zones in more detail.

Bathroom zone 0 
This is the area which is located inside the bath, basin or shower and is defined as ‘any area in the bathroom which can hold water’. Any fitting or appliance installed in this area must be a maximum of 12 volts (SELV) and have an IP rating of minimum IPX7.

Bathroom zone 1
This is the area above Zone 0 extending up to a height of 225cm or the ceiling (whichever is the lower). Zone 1 also extends out to a circumference  of 1.2m meters from the showerhead if there is no shower tray or basis, for example in a wet room or similar. This area is considered the ‘splash zone’where any electrical equipment is likely to get very wet quickly, but would not be likely to be submerged. Any installation in this area must be IPX4 or higher, as well as a maximum of 12 volts (SELV) with the transformer being located outside of zone 2.

Bathroom zone 2 
This area is beyond one, extending up to a height of 3m and horizontally to 60cm. Only SELV devices are allowed in this zone. The minimum IP rating here is IPX4.

Bathroom zone 3/Outside zones
When the size of a bathroom extends beyond zones 0, 1 and 2, portable equipment can be used if it’s flex length does not enable them to be used beyond this ‘safe’ area. Electrical equipment in this area such as light fittings or sockets do not have to have an IP number, however, for your safety, it is strongly recommended that electrical items do have moisture protection.

Bathroom safety – Ingress protection ratings

Ingress Protection Ratings are a system for identifying the level of protection required for specific zones within your bathroom or shower room. Any electrical device which is designed to be used in a bathroom will have an IP rating, including items such as extractor fans, showers, heaters, and lighting. 

IP ratings are always followed by two numbers, the first of which relates to the degree in which the device is protected from solid particles, and the second number denotes the degree to which it is protected from moisture. The higher the number, the better protected it is. 
The information above shows which IP rating each device should have depending on the area in which it is to be located. 


Which light fittings are safe for my bathroom? 

Ideally, all light fittings in your bathroom should be enclosed, as opposed to a light fitting that hangs down from the ceiling. As set out above, light fittings are given IP ratings to ensure their suitability for the zone in which they are located. 

Bathroom light installation in London

SW Electricians can help you with your bathroom lighting installations. From a single enclosed fitting to creating a truly ambient experience using colours, different lighting tones and downlighters, we help you to ensure that your bathroom or shower room offers a relaxing or invigorating experience every time you step in. 


Spotlights for the bathroom

Installing spotlights can be a popular choice for bath and shower rooms, as this offers you a good strength of light, allowing you to easily do everyday things like apply makeup, ensure that you get the closest shave and can see well to keep the room clean. 
SW Electricians are specialists in spotlight installation and can help from the process of planning to implementation of bathroom spotlighting. 


Bathroom light switches

Any light fitting which is not enclosed must be out of reach of anyone using or still wet from the bath or shower. The same applies to your light switches – everyday switches pose a danger because of dampness and wet hands. A ceiling mounted wall switch is the safest option.
