Had a problem before Christmas with our boiler losing pressure. This required 2 visits, customer support was very good at arranging these and engineers arrived and diagnosed the issue . There was a wait for parts, however once parts were delivered the repair was quickly carried out . Unfortunately four weeks later the same problem occurred, customer services were contacted and Paul D attended two days later , he had to return the following week as well, again this visit was arranged very quickly. Paul has always been friendly , very professional and very knowledgeable , the boiler is now operating correctly, thank you.
