EXCELLENT Based on 30 reviews Posted on Google alfred lamTrustindex verifies that the original source of the review is Google. Paul provided professional and reliable service. He is knowledgeable, efficient, and did a great job. Highly recommended.Posted on Google Cate BakerTrustindex verifies that the original source of the review is Google. Luke serviced our boiler today and was exceptionally professional, knowledgeable, and friendly throughout. He took the time to explain the work he’d done and showed me how to get the most efficient use out of the boiler. He even demonstrated how to check the radiators, which was really helpful. From start to finish, everything ran smoothly, and the level of customer care was outstanding. As an extra thoughtful touch, he even gave me some AAA batteries for my daughter’s nightlight after overhearing that I’d forgotten to buy some — such genuine kindness and attention to detail are rare these days! I would highly recommend Luke and the company.Posted on Google SHARON SykesTrustindex verifies that the original source of the review is Google.

Absolutely brilliant service. We decided to have a new boiler as British Gas want over £500 for homecare. 100% gas were recommended by a neighbour who said 'I am that confident that they will do a great job, if they don't I will pay for it myself.' Couldn't have been better, small family run firm, great communication and Luke was great when fitting the boiler. We have not had any problems at all so would recommend 100% gas definately. Don't waste your money on anyone else.Posted on Google Joseph william SmithTrustindex verifies that the original source of the review is Google. I have had an issue with my boiler.
