Foolishly spent 2 years with them, simply AVOID them specially if your boiler is a bit old; their only intention is to sell you a new boiler at very high prices and long term (up to 10 years) contracts that if you scrutinize they are daylight robberies. their trick is to offer you parts and labour on new contacts for old boilers but they don't tell you the details and cost ceilings etc so for any breakdown they take the £75 visit fee and then refuse to repair on cost issues to force you buy a new boiler from them. So do not touch them with a BARGE POLE. Period
