Our Happy Clients!

Matt and Chris were great! They fit us in last minute for a new boiler, were quick, super friendly and did a great job. They explained how to work everything, and even popped back to sort a glitchy thermostat free of charge. Thanks guys, would recommend!
Kayleigh Bertram
I called Kassgas last week who visited and confirmed that my boiler had had it ! Matt was great and offered me a very reasonable price to fit a new one. It’s all done now and working perfectly and I’ve got a 10 year guarantee. Would definitely recommend Kassgas if you have any heating or boiler problems.
