As of 1 January 2005 it is a legal (statutory) requirement for all work on fixed electrical installations in dwellings and associated buildings to comply with relevant standards. The relevant UK standard is BS 7671 2018 (Non statutory)
The EAWR (statutory) says that compliance with BS7671(Non statutory) will mean compliance with it.
The Building Regulations (statutory)
Approved Documents are intended to provide guidance for some of the more common building situations. However, there may well be alternative ways of achieving compliance with the requirements. Thus there is no obligation to adopt any particular solution contained in an Approved Document if you prefer to meet the relevant requirement in some other way.
So where does that leave us? Best is stick to the Regs and treat them as statutory (even though they're not) and you can't go wrong. They are the code we live by.
