Yes, but...
If the point of the buildings regs is to make work in buildings be done to a safe standard, then what SHOULD happen is that any added expense/difficulty imposed by the regulations is reasonable. At the moment, for electrical work, it is most definitely not. This will cause people to do work without telling their LABC at all - so, rather than 'some protection' being afforded by BCOs even just doing basic visual tests, there is no protection at all.
A BCO taking the front of a socket off, and seeing that the right type of wire is in the right holes (and that the CPC sleeving is on
) is better than no checks at all.
Since 2005, I bet some BCOs have retired. How many new BCOs have been employed? (Lots, I bet). How many of those have had basic training in electrical installation standards? (Not many, I bet). A lot of Part P notifications will be ONLY Part P, so sending round a sparky to do some basic tests should be all that's needed, not a BCO who isn't a sparky PLUS a sparky. All that would be needed would be for each LABC to have an electrician or two on their payroll to replace the BCOs who come out to look at Part P work but don't know what they're looking at.
ISTM that the LABCs don't want anything to do with Part P, they only want self-notifying electricians to do electrical work (where they don't actually need to do anything), so they're discouraging anyone else from notifying part P work to them by charging unreasonable fees and imposing unreasonable requirements. The Approved Document Part P is quite reasonable, but LABCs simply ignore bits of that they don't like, and since they're effectively a powerful monopoly, it's hard for anyone to fight them.
