What our customers say
Trusted across Greater Manchester
“Vanguard replaced our ageing combi boiler at our home in Altrincham and the whole job was spotless from start to finish. The engineer turned up exactly when he said he would, the new pipework is beautifully neat, and they hoovered up before they left. We finally have hot water that actually keeps up with two teenagers.”
MF
Margaret Finch
“A pipe burst under our floor in Sale on a Sunday evening and I was dreading the bill. Their engineer arrived within the hour, found the leak straight away and had it fixed before bedtime, all for a fair price he quoted upfront. Genuinely could not fault them.”
JC
James Connolly
“We had a full bathroom refurb done at our place in Didsbury and Vanguard handled everything from the first measure-up to the final tile. They kept us updated every day, stuck to the timeline, and the finish is far better than we hoped. Would happily recommend them to anyone nearby.”
