If your property has not been rewired within the last 25-30 years, it is very likely it will need upgrading, either in part or full to bring it up to current standards. The wiring may be potentially dangerous and may not be able to cope with the demands of modern living.

You  may be able to tell if a house has been rewired recently by inspecting exposed parts of the wiring or by the electricity meter and fuse box (now known as the consumer unit).
