Domestic Installations

Stay safe in your home

Electricity can kill. Electricity is now the major cause of accidental fires in UK homes. Government statistics show that electricity causes more than 20,000 fires a year - almost half of all accidental UK house fires. Each year, about 70 people are killed and 350,000 are seriously injured due to an electrical accident in the home.

Modern living has meant we use more and more electrical appliances in the home. For instance, just 20 years ago the average UK home had a hi-fi system and one TV or video, whereas today it is more likely that there are at least two TVs, a DVD player, a satellite receiver, games console, microwave and computer. So the risk of electrical accidents in the home is much higher than before.

Who should carry out electrical work in my property?

It is important that any electrical installation work is carried out only by people who are competent. This means people who have the knowledge, skills and experience needed to avoid dangers to themselves and others that electricity can create. It's easy to make an electrical circuit work - it's far harder to make the circuit work safely.

Get to know your electrics

Your property will have some or all of the following

Main Switch

The main switch in the consumer unit (fusebox) allows you to turn off the supply to your electrical installation. Some electrical installations have more than one main switch. For example, if your home is heated by electric storage heaters, you may have a separate consumer unit for them. The consumer unit should be easy to get to, so find out where the main switch is to turn the electricity off in an emergency.



Older homes often have rewirable fuses which automatically disconnect (Blow) to prevent danger, these are normally either made from Bakelite and will have a piece of fuse wire fitted between two terminals or are fitted with a fuse similar to a plug fuse. It’s important to point out that these types of safety devices only protect the circuit and cables and will not protect you from electric shock.



Newer homes or those rewired within the last 25 years are likely to have miniature circuit breakers installed. These switch off when a fault is detected. Once the fault has been identified and repaired the circuit breaker can simply be switched back on to restore power to the previously faulty circuit.

Residual current devices (RCD)

An RCD or Residual Current Device is a lifesaving piece of your electrical installation. It is designed to prevent you from receiving a fatal electric shock if you touch something that has become live like a bare wire. It provides a level of protection not offered by fuses or circuit breakers alone. It is now a requirement for all circuits to be protected by a residual current device. For more details on residual current devices please see the separate article:  What is a Residual Current Device


How old is your wiring?

Faulty and aging wiring is one of the major causes of electrical fires in the home. You can avoid these risks by having regular checks carried out on the condition of your cables, switches, sockets and other accessories. There are clear signs that can help you tell the age of electrical installations in your home. These are:

  • Cables coated in black rubber (phased out in the 1960s);
  • Cables coated in lead or fabric (before the 1960s);
  • A fusebox with a wooden back, cast iron switches, or a haphazard mixture of fuse boxes (before the 1960s);
  • Older round pin sockets and round light switches, braided flex hanging from ceiling roses, brown and black switches and sockets mounted in skirting boards (before the 1960s); and
  • Wall-mounted light switches in bathrooms (before the 1960s).




Your consumer unit should look like this:
A. Main Switch
B. Miniature Circuit Breakers (MCBs)
C Residual Current Device (RCD)
If you don't have one of these devices
fitted you could be at risk of electric shock.
