I felt I had to put down in writing my profound thanks for the work you carried out for my mother recently. The details of which are, Mark was booked to visit my (quite old) widowed mother, for a job on her boiler. He inspected the system and then advised her on the best course of action, in plain straight-forward English, taking his time so she was sure to understand everything. This resulted in a substantial saving for my mother (over £400), but more importantly gave her peace of mind during what was a very distressing time for her. I would also like to state that I would have absolutely no hesitation in either using you or recommending you in the future.
