Went to look at an electric boiler not working.
Isolated the boiler at the rotary isolator and CU, phoned the owner and left.
Anyone with a stellar memory may recognise the CU as one I posted last year. Apparently the same guy who installed the boiler fixed all the issues I highlighted on the EICR.
Sent a cover my arse e-mail as soon as I got home with advice to get another opinion and another spark.
Funnily enough my quote to rectify all the rubbish I had previously highlighted was rejected as too expensive. Hence the sulk and leaving him to it.
