What customers say

68 reviews and counting

Our goal: the most reviewed heating company in West Dunbartonshire, Helensburgh and Loch Lomond.

“Boiler died on a Tuesday morning. Phoned at nine, price by half nine, new boiler running by teatime. Nothing added on the day. Can't fault them.”

Margaret H. · DumbartonBoiler Installation · Google

“Two other firms told me I needed a new boiler. Sure Point fixed it for the cost of a part and told me it had a few years left in it. Honest lads.”

David R. · ClydebankBoiler Repair · Google

“Converted our old system to a combi. Big old house, lots of pipework, and they still finished in the day and left it spotless.”
