I think you’ll probably find a better quality of install in general from meter fitters than electricians. An electrician technically isn’t qualified to work on a meter install. This results in some bizarre scenarios were rather than cut the seals on the mains and meter and fit new tails the sparky will cut the tails while they are still live and fit the new tails to the old with choc blocks. Exposed lives, loose terminals, tails too short for the terminal all very common from Sparky’s as no one follows up on there work.And so it should be.
Just a bit unnerving that dilutees can go into peoples homes and install stuff when they are not fully qualified tradesmen.
But I am "old school", and I do realise that these days a lot of people are doing jobs with just a "course " under their belts.
