Had young Matthew pop over to fix a leak and connect our stove and a few other little bits in our new property. He is a really nice young lad, professional, reliable and honest. The rates were also more than fair. Will definitely be using LW Gas for any future needs!

Great service, friendly and useful engineer who kept to social distance measures, and wore a face mask.

BRILLIANT... Highly Recommended. I didn't want cheap, I wanted the best boiler and central heating upgrade I could afford and a quality, trusted service. Lee provided a detailed quote with three alternative prices with no hidden costs. The installation carried out by Mark, Lewis and Mitch was first class, thank you. So pleased with the Bosch Greenstar boiler ... money well invested.

Although installation not happened yet. These guys are really professional. They have done other work for me and turned up when they said they would and cleared up after. When they did quotation they were thorough and considerate and efficient. They are also competitive. Will post again after next week.
