Electrical Safety First strongly recommends that, wherever you live, you use an electrician registered with one of the government-approved schemes to do any electrical installation work that you need.
They work to the UK national safety standard (BS 7671) and will give you a safety certificate to confirm that their work has been designed, inspected and tested in line with that standard.
All of the government-approved scheme operators have a complaints procedure. They investigate any complaints about registered electricians who have not complied with the appropriate technical standard.
