Highlights
"Rob attended our house on 3 occasions and was exemplary every time. The initial visit involved a routine boiler service and radiator balance which ended with our boiler being shut down due to a faulty flue cap fitted by a previous company. Rob returned the next day, as promised, with the correct cap and everything worked perfectly. He had noted a leaking water tank which, again, having sourced the appropriate parts, he returned and fixed. Superb service and would recommend without hesitation"
"Plumber arrived on time. Courteous and friendly. What he doesn't know about boilers I don't think has been invented! I'd been without a working boiler for a few days. He fitted a new boiler for me + removed the old one at a very reasonable price. He went through the instructions with me and left me with a lovely warm home. I can't praise/thank him enough."
"Great service overall. Following the service the pressure in the boiler dropped a cpuple of times over the weekend. Rang at 8.30 Monday morning and the engineer came back that afternoon and replaced a part. I will definitely go back if any other issues arise."

Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check — a layer of accountability an unregistered trader doesn't offer. Around 6 years on the register also points to an established business rather than a brand-new one.
