What can I say, Kassgas are a company that go over and above. Originally called them out to repair a leaking boiler, which then decided it wouldn’t work and they came back again the same day to sort.
The issue causing the boiler to not work was nothing to do with the work they had done earlier that day and due to the sink waste pipe not being connected!! However they spent about an hour and half sorting this issue for me and charged nothing extra. Such a friendly, kind and personal service and will definitely be using them again and would recommend them to friends and family. Thank you, you were amazing.

I called kassgas after my boiler stopped working and started leaking water, engineer came out found it need and new expansion vessel, gave me a quote very reasonable i thought so we went ahead. Two gents turned up today and changed vessel only to find I think it was the sensor they said was wet so the fan wasn’t working, they didn’t just say you need a new one like some others I no doubt would, they asked for my wife’s hairdryer and set to work for ten minutes trying to dry it out. Well to my surprise they fixed it. To say I am super happy is an understatement not only with saving money but with the genius of these two gents to not just go that’s broke that mate. Cheers kassgas will definitely use again.

Had a new boiler installation plus 3 rads and an outside tap installed recently. The service from Kassgas was excellent from start to finish. Billy and Matt were super quick to come over and provide a really competitive quote. The communications have been first class from the start, Billy is great at replying to any questions you have. And the installation was done in super quick time, professionally and cleanly. They are professional, courteous and friendly people, I have no trouble in recommending Kassgas for your plumbing and heating jobs and will be using them for all mine in the future.
