I’m not an electrician, but all ‘new’ electrical work here in the UK requires a certified electrician carries out and signs of on the work. They can inspect and test existing electrics, but only to say if it meets minimum standards or not and is safe to use.
On my current house, we converted a garage and utility room into a bedroom and ensuite for my mum. Even though there were some electrics (2 sockets and 3 lights), we effectively had it all redone from scratch, with the electrics for that entire job placed on it’s own ‘breaker’
I then had another bedroom and ensuite reworked, not really much in the way of new wiring… mostly just moving existing stuff around (sockets, switches and isolators for extractors), but still signed of and certified by an electrician.
Redoing existing electrics is fine, so you can replace switches and sockets, light fittings and so forth without any issues.
