The gas angels team I installed my new boiler a new year's back and they did as such a great job. Since, we've had yearly boiler services with their monthly payment plan and they always do a great job with that too. Dave and Gary are very friendly and professional and are always happy to help with any inquiries too, as are Dave's wife and admin team (that we've spoken to over the phone over the years). Before we had gas angels install our boiler we had numerous issues with other companies/plumbers, and since we've used gas angels I would recommend them every time!
