First visit: engineer never turned up. Claims he did and rang doorbell but someone was in all morning and the doorbell was working fine. Second visit: was supposed to arrive 10-12 but got stuck and wasn’t able to turn up till 2:30 which meant that it would have been 5pm finish which I’d already said the job had to be done by 4 Third visit: engineer turned up and did the job. Recommended getting a new fuse to upgrade from 60A to 100A to take the load. Found out he had fitted 16mm tails even though he knew they couldn’t be used with 100A so had to get those changed at a cost of £90. He also doubled up the earth instead of setting another one, which I’ve been advised shouldn’t be done and is dangerous.
