I had a new combi boiler fitted, no radiators and it cost me almost �5,000 with British Gas. They threw in a "free" bathroom radiator and insulated my loft and walls for only �450 as part of the deal. I went with them as I felt it would be safer. After hearing of quotes for around �2,000 for a new boiler I wish I had taken a chance and gone with someone else. Didn't think at the time, but the boiler would after all have had a guarantee wouldn't it? Oh well a lesson for the future.
