Add to existing lighting and mains circuit

Yes, part P of the building regulations will apply. Failure to abide can be costly as some local authorities are now prosecuting and fining people! (Max fine is £5000). The new sockets must be RCD protected to comply with BS7671:2008 (as ammended to 2011). The lighting circuit extension must also be RCD protected as all electrical cables that are buried below plaster depth in walls and ceilings and athat are not installed in an enclosed earthed metal screen (i.e. metal conduit etc), must be RCD protected. The electrician doing the work must issue you with an Electrical Installation certificate and register the work online with building control, so that the building compliance certificate is issued.

Hi mo You can do it yourself and get the council to look at it and sign off. Or post on here for an electricain to price up who ,yes can sign off under part p etc Hope this helps Regards Richard

yes of course ,any alterations or configurations will have to comply with building regs ,you should have this in the pack building control send when you pay for your inspections

Yes, certification will need to be provided to you and building control will need to be notified via one of the Part P regulators. By law you should only employ a Part P registered electrician for any domestic works. Look for a company registered with either: NICEIC / NAPIT / ECA / ELECSA.
