Had problems with pressure dropping on…
Had problems with pressure dropping on boiler. Ryan came out fast and identified the problem and fixed it. We also mentioned concerns of smelling of gas which he promptly investigated and he detected a gas leak at the main meter. This was resolved immediately and we cannot thank him enough. We would highly recommend him. The fees were very reasonable. Both reliable and professional. We would definitely book him for any further work in the future. Thanks Cliff

Excellent service
My central heating boiler had a serious safety problem which, Ryan, diagnosed and fixed. The job was not an easy one. Removing the faulty part proved difficult because it was so damaged. But Ryan persevered and got my boiler safe and working efficiently. I will ask for him by name the next time my service is due.
