The ImpraGas Staff have been great. They beat my 4 previous boiler quotes, and even managed to fit my new Worcester Bosch much sooner than originally expected. The boiler fitter arrived exactly on time and had no problem fitting my new boiler by mid afternoon, leaving no mess atall at any point in my flat. I am delighted with the boiler and on the first evening the team phoned me back immediately when I had a question about the brand new thermostat. Very reassuring. Do not hesitate to give ImpraGas a call. HIGHLY RECOMMENDED.
