Contacted Andy after being let down by British gas, he was recommended by a friend and the Service was incredible! He fixed my elderly mums boiler within hours of my call, the other company who she has a Service contract with couldn't come for two weeks. He was really friendly extremely helpful and will now be our go to gas engineer thank you and highly recommended

We were really impressed at the quick attendance and quality of work by Andy and Tim. We were given options of repairing or replacing our gas boiler and took the decision to replace. The work was carried out within a few days and to an exceptionally high standard. We would have no hesitation in recommending AGW and would definitely use them again.

Andy and Tim fitted our new Worcester combi boiler, they were efficient and knowledgeable. The work was carried out to a high standard and our kitchen was left in a clean and tidy state. Being a local trader its good to know that they are close by and will call in if we have any problems. I would recommend this company.

Andy and Tim have done an excellent job replacing my old Potterton boiler and Boilermate tank with a much more efficient and controllable system and it only took 2 days as Andy said it would. I'm really pleased with it all and it was a pleasure having them in the house. Not only were they very efficient, tidy and cheerful but also very mindful of lockdown safety. They're a great team and I've already been recommending them to friends.
