I can't recommend Alec highly enough. He is a pleasure to work with, intelligent, reliable, efficient, and thoughtful. The existing boiler in our house was mounted very high on the landing to the first floor and inaccessible without a ladder. Over the last 4 years we've had it repaired dozens of times and each time considered buying a new one; we would have if any of the many tradesmen we dealt with had given us good advice about an alternative location for installation. None could. Late winter last year the boiler finally stopped working altogether and in desperation I sought yet another tradesperson through Streetlife where, thankfully, I found Alec. His reviews were fantastic and he's as good as everyone says. He called me back the same day, visited the next morning and assessed the situation thoroughly. He quickly spotted an alternative location for installation in the understairs cupboard, advised us on the purchase of a German boiler small enough to be installed there, and completed the work in 3 days over the weekend. He and Marco are artists as well as tradespeople and the pattern of installation of the new copper piping is a thing of beauty. We are also grateful to Alec for suggesting we install the Tado mobile app to control our boiler remotely and provide automatic temperature regulation while we're away. Now we save money while enjoying a completely silent boiler along with worry-free and environmentally-friendly heat and hot water. Email or ring him!
