We were vulnerable as boiler not working. No heating or hot water. Tried various plumbers, not able to come out quickly so we had to go with these, despite misgivings. They want your credit card details up front, and charge very high prices. Engineer came, kept rolling his eyes, warning me it was going to be very bad. Said the whole system needed flushing out and quoted £900 plus Vat. Said he had got the water sorted but couldnt sort the central heating. Phone me when you decide he advised but if you don't do something soon your whole boiler could break down completely. They took the call out fee of £94 from my credit card. Then after he left checked water but it wasnt fixed, still cold!! Got a reputable plumber who laughed, said" excuse my french but what a f.......g c...t and sorted the problem in fifteen minutes. Avoid this company at all costs, read the bad reviews, they are enough of a warning! Can't decide whether to complain as apparently you just get abuse and don't suppose i will get my money back.
