Context: I live in London and getting a good gas heating engineer is like hens teeth.
I asked our friendly but loosely reliable existing engineer to attend on the 12th October last year as heating upstairs wasn’t working. He had managed the system for years.
He arrived whilst I was out (kids let him in) and left, with no word, and the heating still not working.
After I chased him several times, he ordered a part that was then ready to be installed. He visited again on the 12th November, exactly the same as before, I wasn’t in, he left without fixing it.
I chased him a few more times and he avoided me, so eventually I got another company in to fix it. They charged me £180 and said basically the valves weren’t fully open. There was a separate problem with the hot water system that would need sorting though.
I contacted our existing engineer and explained the situation asking him to now fix the hot water.
He attended (12th December) and did so.
Fast Forward to today, he’s now sent me a bill of £300 made up of Boiler service and repair £190 and materials £125.
Because of his incompetence we were without heating upstairs for two months and I had to pay another company to fix his errors.
I feel that I shouldn’t pay his bill.
YABU - He carried out some work so should be paid
YANBU - He was incompetent, ignore abd find a new engineer
