We have used Diamond heating for a number of years to service our boiler. We recently had to replace it and they were our first choice to carry out the work. They arrived punctually at 8.00 and had finished by 12.30. They treated the house with total respect, covered everything, were very polite and understanding. They carefully talked us through the new boiler controls and answered our questions in a very understanding manner.

Cannot rate them more highly and would recommend them without reservation.
