Hi, I got a plumber round to change the pipes for 3 radiators to one. They aren't quite in the right place but luckily there is some give so at a stretch we can make it work when we install the radiator. He quoted to do this and install Hive for £160. Seemed like a nice guy until he broke the boiler installing the Hive and left us with no hot water or heating. He said he would come round on Sunday if someone had a part or Monday after his day job to try and fix it. I'm pregnant so a weekend with no hot water or heating wasn't really an option so we got British Gas round to fix it. He has since sent an invoice for the full amount. Are we being OTT to think that's a bit cheeky seeing as he didn't install the Hive and left us without a working boiler?.. how much do you think we should pay him?
