A boiler was fitted in my 88 year old mothers house in 2013 the boiler keeps breaking down, it was only fitted a week when we had to call out the engineers and this has been the case since and every 3/4 months we have to call out an engineer to fix this boiler. I was told that there must be a leak somewhere so I called in an independent engineer who found 2 couplings loose and tightened them but the boiler is still breaking down, SIME sent out an engineer who took the boiler apart then said that is it fixed and it is still breaking down. I called B&Q today and they said it is SIME to blame, I said this is the last straw only to be hung up on by the B&Q employee. I then spoke to SIME who said it was B&Q's fault, not one of these companies are willing to take the blame and fit a new boiler for an 88 year old woman who has the start of dementia and is often found sitting in her own home in minus temperatures. I might add that B&Q told us the boiler had a 5 year guarantee but SIME said it only had a 2 year guarantee. B&Q say it is a SIME manufacturers fault the manufacturer says it is B&Q fault. I am now looking to get information on all the calls made to these companies to take them to Consumer right.
