> — Customer in Surrey (5.0, via Which? Trusted Traders)

> "GMH replaced our 50 year old gas boiler, and all radiator valves. The quote was roughly in line with other quotes. They turned up on time and completed the work efficiently with minimal disruption. Communication with the company was good. Gary explained clearly what was going on and was happy to talk through options. The work was done on time and to budget. I can't comment on after sales or servicing as the installation was recent. Would recommend."
