This company is well-named: they quickly diagnosed that our old boiler was finished - I think we knew that from its death rattle. They then set about replacing it, working in a team of three and not wasting a moment. All the guys were very friendly and we enjoyed their company. But most important they replaced our boiler in less than one day with a brilliant new one, replaced the old taps on the radiators and, by the time they left at 10pm, the whole system was working wonderfully and now all we have to do is to read and understand all the instruction booklets they left. We will recommend Fast Response to anyone who needs a new boiler fitted quickly and without fuss.
