Condensed version, moved into new build shared ownership. Boiler and under sink has been plumbed in wrong. Had no hot water, which is now fixed, but washing machine and dishwasher are still on hot water pipe not cold. DM thinks I should complain and claim compensation, I'm not so sure.
Long version.
So DP and I have finally managed to buy our first place. It's shared ownership, and we moved in almost two weeks ago.
We noticed pretty much straight away that the hot water wasn't running properly. Kitchen seemed OK, but all the other taps were very intermittent, and the shower/bath wouldn't draw hot water at all.
Builders sent an engineer, who flooded the kitchen (thankfully not big as I turned the mains off pretty quick), and said it was a part missing in the boiler, and needed to call the manufacturer. He left us with no heating.
Boiler engineer couldn't get to us for 5 days, and builders couldn't get anyone out to us before. Rang the HA, they sent an engineer who got the heating back on the next day, but who also flooded my kitchen (again minor thanks to me), and said the boiler was fine, but piped in backwards. Needed to be fixed by the builders.
Builders booked someone in, but kept the boiler manufacturer appointment so the could check the boiler over just in case. Boiler person confirmed the plumbing was backwards, but that the boiler was OK (checked the gas installation as well)
Builders sent someone, hot water fixed, but after noticed that the cold water feed for my washing machine and dishwasher is actually plumbed onto the hot water pipe. Builders have said they will try and send someone next Monday or Tuesday, but I won't hear until the day. If not, it'll definitely be straight after the Christmas period. They've also agreed, at my request, to have all the pipework double checked. They've apologised, and also stated they won't be using the original plumber again.
My mum reckons I should complain and claim some sort of compensation. I'm not sure as they have done all they can to rectify it as quickly as possible, and I've had follow ups, etc.
What would you do?
