This Company shouldn't be in Business. BEWARE. ABSOLUTE COWBOY's I used them to investigate a problem with my Central Heating. Although they came within 3hours they misdiagnosed the problem, charging for a part that worked prefectly well together with a Labour charge that is downright obscene & after a £120 + vat call out charge as well! The Problem persisted but when I called I was told that if it wasn't a misdiagnosis I would be liable for another call out charge! A Independant Engineer verified the misdiagnosis & was traced to a faulty pump, £85 to replace + his labour..... basically less than 25% of the rip off charge that these bandits charged. Various attempts to contact via e mail to discuss the misdiagnosis & costs associated have fallen on deft ears. I paid by CC so will take the issue up with my CC Company. AVOID THEM AT ALL COSTS.
