Quite a few good things, in fact.
Satisfied customer
The new boiler did not turn up the day before installation as arranged. However, Jack, the Gas Safe engineer, arrived with our new boiler before 9am. The installation went according to plan and Jack was done at 15.15. I was kept informed throughout and received all the manuals and verbal instructions on the basic user controls. All of the old boiler fittings and parts were taken away and the house was left clean. I have since received the warranty certificate and gas safety certificate via email.
