my first post and almost certainly not my last.
We moved into a five bedroom house last year that had obviously once been a B&B.
The wiring was a nightmare and the local electrical firm blanched when they saw it.
They've made it "safe" and also put in a new CU with RCBO's.
They advised me to totally rewire the bedroom plinth heaters that use a four wire circuit. (Fourth wire for a master controller). To that end I'm now running new four core cable in a proper ring style to all the bedrooms.
Whilst doing the above wanted to also run a new ring to supply undersink water heaters for the vanity units.
I can say, "hand-on-heart", that I shall get the electrical firm to come in and do all the necessary checks and final connections to the CU but am worried whether I should have informed Building Control.
Also, will I need to leave access for the cable runs to be checked under the floorboards?
Thanks in advance.
