My boiler's pressure was way too high and being quite loud. Ray gave the boiler a service and could see the issue. He explained what the issue was, which was nice to hear as you could relate to what you have been seeing and hearing to what is causing the problem. He came back to repair the boiler, at the agreed cost, and now the boiler is working absolutey fine. Very happy with it, both service and repair was completed promptly. I will be booking Ray in for a boiler service next year.
