I really can't recommend Heatable highly enough. We found them on the Thursday morning, had a couple of queries answered via Sam on the online chat (at half 7 in the morning!) and placed our order there & then for Saturday. New combi boiler to replace the existing, and to have it relocated to the opposite side of the house. Dale pulled up at 7.50 and got to work. By 10 past 2 he'd had the floors up, put the new pipework in, fit the boiler & new flue, tidied up, ran me through how the heating system worked and left us with heating & hot water for the first time in nearly a fortnight! Absolutely superb, tidy job - no fuss, no mess. Monday we noticed the boiler was coming on for a few seconds when we turned the cold water taps off. Again spoke to Ben on the live chat who suggested a couple of things to try to resolve the issue, however once these didn't work he quickly dispatched Shaun to come and fit a non-return valve to prevent this from happening (it's an old house, and without ripping everything out and starting from scratch there were bound to be one or two teething problems). Again in & out, no mess and no fuss. Overall if you're looking for a good price, quick installation, decent service & after service then you can't go wrong with Heatable.
