I would absolutely recommend Alliance Heating & Airconditioning. Paul did a great job of checking our boiler, explaining how it works and recommending ways to keep our gas bill down - very much appreciated.! Paul was professional, friendly and courteous and we'll definitely be using Alliance in the future. Five stars!

Thanks to Paul and Lee for fitting my new boiler. Paul has been my plumber for a few years now. He is reliable and efficient. Paul arrived on time and left everything clean and tidy. Paul is the best plumber that I've had and I would not hesitate to recommend him. Thank you Paul.

Paul serviced our boiler and gas fire, and has done this annually for a number of years. As usual, Paul is reliable, professional and courteous. He always does an excellent job. Thank you Paul.

Absolutely fantastic service. We had no water coming out of the hot taps and did not know why. Assumed it was an air lock but nothing worked. We looked on Trust Pilot for a local Heating and Plumbing Service with high recommendations and found Alliance. We made a call and Paul came later that day. He had a good look at the tank in the loft, the taps and the hot water cylinder and determined that the problem was the hot water cylinder. He answered all our questions and explained in detail what needed to be done and how much it would cost. A few days later the job was done. Paul is a real gentleman, polite, professional, respectful, knowledgeable and someone you can trust to do a fantastic job. The work was done to a high standard, with care and respect for the property, there was no mess and we are very pleased with the finished outcome. Would recommend Paul and Lee to anyone.

I have been using Paul for over 13 years now, it’s rare to find someone these days who is genuine and honest. I’ve recommended Alliance Heating and Plumbing to several of my friends who have all been very impressed with the work that they’ve received. I would highly recommend Paul to others and personally wouldn’t use anyone else!
