Hi am new to forum. Just had 4.5day bathroom installation. Bathroom v good however was told on initial survey we wont need to touch your electrics - was keeping original Mira Sport shower and spotlights. Day 1 was then told "our sparky wont pass them, you need new spots, need bathroom rewire" this then led to "need new fuse board with rcd" ok. ÂŁ480. Ok. We have a hotwater tank that was on a Diall timer (and worcester bosch CH only boiler) only moved in 1 month ago but worked perfectly timed at night on economy 7 tariff. Discovered to horror on thursday that timer been removed "cos its not safe" think timer fine, i still have it, but there was no trip for it on new fuseboard, something about incorrect current loop? So to stop a permanent tripping out theyve replaced timer with a fused manual on/offswitch? Wire from top of tank old and casing snapped of in places - not replaced. Ongoing argument about this but they say sparky says "its now safe". Other plumbing issues, leaking sink, stole my existing shower head replaced it with naff plastic one. No reasons given.My husband has paid them in full my question is what is safe/advisable re hot water tank and what paperwork should i have re installation of fuse board/new spots/partial bathroom rewire/extractor etc. I spoke to the sparky on Tuesday in person he was knowledgeable but they got him to complete job wen i was out on Wednesday. (I was told Thursday and had booked the day off )Bathroom company say "there is no paperwork" they came highly recommended but since found out they never issue paperwork even receipts! What should i have been given and how do i get it tested to make sure its now safe? Electrician said on Tuesday i ideally need a whole house rewire this would be "ÂŁ3to5k"? It looks like its black/red cabling which is ok but been diy-ed. Family member who does commercial looked it over before the bathroom debacle started when on old fuse box said it was safe but didnt test sockets etc. Tearing hair out here, please help. They sending sparky back next week as gesture of goodwill but i dont know whether to use him/report to trading standards? I've no leverage cos husband paid thank you
