Installing Sockets in the Bathrooms

Sockets are not allowed to be installed in bathrooms or the shower rooms (apart from shaver-supply units), unless they can be fitted at least three metres from the bath(bathtub) or shower. Shaver-supply units must be a safe distance from the bath or shower to avoid splashes.

Installing Lights in the Bathrooms

Enclosed ceiling lights are preferable to the pendants (the ones that hang down from the ceiling) light fittings. All the light fittings that are not enclosed, should be out of reach of someone using, or still wet from using, the bath or shower.

The IP rating for the light fittings that are to be mounted in the bathroom has to be high enough for them to be fitted there – see the permissible IP ratings for the bathroom lights. A ceiling-mounted pull-cord switch with the cord made of insulating material is the safest option for a bathroom. Standard wall-mounted light switches are a possible danger because of dampness and wet hands.

Installing Heaters and towel rails in the Bathrooms

Central heating is the safest way of keeping a bathroom warm. But if you have an electric room heater, it must be fixed at a safe distance from the bath or shower – it has to be outside of the reach of the splashing of water.

The electric and gas water heaters in a bathroom must be fixed and permanently wired, unless they are powered by a socket fitted three metres from a bath or shower. Electric heaters should preferably be controlled by a pull cord or a switch outside the bathroom.

Safely Installing Showers

An electric shower must be supplied on its own circuit direct from the consumer unit.

Please Don’t bring any mains-powered portable appliances such as hairdryers, heaters or radios into a bathroom. You could be severely injured or die. You can get a fixed hairdryer with hot air delivered through a flexible plastic pipe installed in bathrooms.

These tips, along with other Electrical Safety Considerations for Home Appliances & Home usage – can be found on the Electrical Safety Council website. Remember: when you want to install the Bathroom Lights, the Bathroom Sockets or the Bathroom Heating Solutions / Hand Dryers, you have to keep in mind these simple rules and even better, consult an electrician.

The Intensity LED Range compared with low grade imports

Energy Saving Conversion Chart – consult below some basic characteristics that differentiate low grade imports from the Intensity LED range:

Low Grade Far East Imports

• The Cool White (6000K) colour temperature is creating a cold harsh light;
• The narrow beam angles gives the impression of bright light at close distance;
• The poor lux level performance at distances over 1 metre;
• The low grade components often result in early life failure and loss of light levels over burning period of lamp.

The LED Range

• The warm white (2700K) colour temperature is creating the same light as a standard halogen lamp;
• The flood beam angle (38º) that is required for general purpose lighting;
• The high performance CREE LED generate lux levels at 10x that of average imports, for example:
  - 3 x 1w LED GU10 = 108 lux/1m (average import);
  - 3 x 5w LED GU10 = 620 lux/1m (Intensity);
• The high grade components guarantee a 30,000 hour life and constant light output over the burning period of the lamp.

As recommended by the NICEIC specialists via their FactSheet about Part P of the building regulations, here are some of the main things that need to be emphasized in order to have both a safe electrical installation and a safe life within our home. Being something that we use everyday, it is easy for us to take electricity for granted. If you attempt to do DIY(Do It Yourself) electrics or use an unregistered electrician to carry out work in your home you could be putting the life of your family members at risk. It is a fact that each year around 12,500 house fires, 750 serious injuries and 10 deaths are caused by unsafe electrics in the home of the people who live in the UK.

About the Electrical safety laws

The NICEIC registered electricians have already helped to improve the standard of electrical work in the UK. An electrical safety law, Part P of the Building Regulations was introduced by the Government on 1st January 2005 with the aim of further enhancing the protection of homeowners and also for reducing the risk of electric shock when using electricity. The law – which applies to England and Wales – aims to improve electrical safety in the home and also to prevent the number of accidents(which are caused by faulty electrical work).

Basically, this law brings the electrical work in the home under statutory control along with other types of building work, such as gas installations. The law requires an electrician registered with a government-approved scheme – such as the one operated by NICEIC – to carry out most electrical work in the home. After completion of any work your NICEIC registered electrician will issue you with an electrical safety certificate and a Compliance Certificate to confirm it meets the requirements of the Building Regulations. You can only carry out electrical work yourself if you can inspect and test that it is safe for use. To comply with the law you must notify your local building control office before you begin any work and pay the appropriate fee for them to inspect the work.

What will happen if you don’t follow the regulations?

• You will have no certificate to prove that the work has been carried out by a registered electrician, or that the work performed has been passed as safe by your local building control.
• It may be problematic when it comes to selling your home if you cannot produce evidence that electrical work has been carried out in accordance with the Building Regulations.
• It is a criminal offence to carry out work that does not comply with the Building Regulations, with a maximum fine of £5,000.
• Your local building control may insist that you re-do the electrical work.

What electrical work does the Part P law cover?

The requirements of Part P apply to most electrical work in your home. There are however, certain relaxations that apply for minor work.

Minor work
The ‘Minor work’ is the electrical work that does not involve the addition of a new circuit, for example adding new sockets or light switches to an existing circuit, or the replacement of sockets, light switches and ceiling roses. This work does not have to be undertaken by a registered electrician and you do not need to notify your local building control office. However, ALL electrical work must comply with BS 7671, the wiring regulations. Here is some help on how to apply for Building Regulations Approval.

High risk locations
Kitchens, bathrooms and gardens are classified as ‘special locations’ because the risk of electric shock is greater. Unless you are only replacing the electrical accessories, any other electrical work in a kitchen, bathroom, garden or outbuilding must either be undertaken by a registered electrician or notified to building control. With so many electrical appliances in your kitchen, combined with the mixture of hot surfaces and water, it is important that the electrical installation is safe. When installing a new kitchen, it is advisible you use a registered electrician or kitchen installer to do the electrical work. External electrical installations can be particularly hazardous due to the presence of water and the extremes of weather, which can make equipment deteriorate faster. If you are unsure, check with a registered electrician or your local building control office before starting any work.

How do I know when to notify?

Check out the list below: it provides a quick-reference guide to which type of electrical work should be notified to building control or carried out by a registered electrician(YOU: you can undertake the work yourself to BS7671, there is no need to inform building control, however NICEIC would recommend you use a registered electrician to carry out any electrical work in your home; Registered Electrician: you must notify building control or use a registered electrician).

Presence Detector Types

1. The switching detectors without lux (light) level sensing
   These detectors are suitable for switching lighting in rooms without natural daylight. They can also be used to control heating and ventilation loads.
2. The switching detectors with lux (light) level sensing
   Ideally suited to switching lighting in rooms there there is a natural daylight.
3. The dimming detectors
   These presence detectors have a wide range of functionality to enable the lux (light) levels to be maintained while at the same time using the minimum amount of energy. They are ideally suited to applications where maximum efficiency and flexibility are required.

1. The Switching Presence Detectors without Lux Level Sensing

The Presence Detectors without lux level sensing are ideally suited to switch lighting in rooms without any natural light. These particular products can also be used to control heating and ventilation loads. The way these Detectors without Lux Level Sensing work is:

• If there is No Presence Detected, the lights are switched off;
• If Presence is Detected, the lights are on.

Example of such Switching Detectors: the SPIR-F(PIR presence detector with time delay function).

2. The Switching Presence Detectors with Lux Level Sensing

This kind of presence detectors have built-in adjustable lux sensors which will keep the lighting switched off if there is sufficient natural light in the area they monitor. All ceiling mounted PRM presence detectors can be set up from ground level using the available simple programming handset. Also, a wide range of user infrared controls are available for increased flexibility. The way these Detectors with Lux Level Sensing work is:

• When no presence is detected, and there is daylight, the lights are off;
• When presence is detected and there is sufficient daylight, the lights are off;
• When presence is detected and there is insufficient daylight, all lights are on;
• When no presence detected, the lights are off.

Examples of such Switching Presence Detectors: the PDS presence detector(No neutral PIR presence detector with lux level sensing and time delay function), and the PDS/OV(No neutral PIR presence detector with lux level sensing, override switch and time delay function).

3. The Dimming Detectors with Lux Level Sensing

The Direct Dim technology from CP Electronics incorporates the dimming functionality plus a host of additional advanced features into the device. The way the Dimming Presence Detectors work is:

• When no presence is detected and there is daylight, the lights are off;
• When presence is detected and there is sufficient daylight, the lights are off;
• When presence is detected and there is some daylight, the lights are on and dimmed to maintain lux level;
• When presence is detected and there is insufficient daylight, the dimming detector measures and implements maintained illuminance;
• When no presence is detected, the lights are off.

In addition to presence or absence detection and the lux level sensing, the dimming detectors are able to provide automatic control of lighting output. A dimming detector can be used to control the light output of lights that are fitted with dimming ballasts. The detector measures the overall light level in the detection area and calculates the correct output for the luminaires, to a maintained illuminance (preset lux level), thereby saving energy by using natural daylight. Many lighting schemes can be ‘over lit’ because of the initial brightness of the new lamps, over compensation for dirt/lamp life, and over-design due to room shape and size. Therefore, the installed lighting often needs to be ‘dimmed’ to achieve the correct illuminance level, and increase gradually to compensate for the anticipated light loss.
