What customers say

Based on genuine customer reviews

Homeowners needing a replacement boiler or a heating upgrade call on Gassed Up Heating Ltd for work that includes Vaillant and Viessmann installations, a new combi boiler with a complete system flush, the fitting of Hive thermostats and smart heating controls, and the correction of suspect pipework. Reliability and punctuality come up often, with accounts of a broken boiler inspected and quoted for promptly and a call-out when hot water had failed.

Reviews time and again mention that the engineers arrived as arranged and completed the job efficiently. Clear quotes and fair pricing are highlighted, along with communication before and after the work, as customers were kept informed and consulted about their preferences during the installation. Tidiness is a frequent point, since work areas were left clean and tidy once the job was finished.

Dan and Ollie are named for their courteous manner, with Dan taking time to explain what needed doing. Expertise and advice feature strongly, particularly the speed of diagnosing faults and the decision to carry parts that might be required, while the flushing of the system and the careful replacement of pipework in a tricky spot show attention to detail on more involved projects, which customers describe as careful workmanship from start to finish.

Dan at Gassed Up Heating Ltd provided outstanding service. He was friendly, professional, and clearly knew exactly what he was doing. He took the time to explain the work, made sure everything was completed properly, and left everything clean and tidy afterwards. It’s rare to find someone so reliable and dedicated to doing a great job. I wouldn’t hesitate to recommend Dan and Gassed Up Heating Ltd to anyone needing heating services. Brilliant service from start to finish!

I had an excellent experience with Daniel from start to finish. I emailed late on Friday 27th February while searching for reputable local engineers and found him through the Vaillant website. Despite it being the weekend, he replied early Saturday morning and even came over that afternoon to inspect my broken boiler and gather everything needed for a quote. By 7pm the same day, I had a clear and detailed quotation. Daniel was incredibly respectful throughout — he took his shoes off at the door without being asked, communicated clearly, and never made me feel rushed. After receiving the quote, I realised I hadn’t asked about TRVs. Daniel responded instantly and offered to install five TRVs at no additional cost, which I really appreciated. Between receiving the quote on 28th February and the installation date on 4th March, Daniel answered every question I had about the boiler and the installation process. He was polite, calm, responsive, and knowledgeable, which made choosing him as my installer an easy decision. On the day of installation, Daniel arrived on time at around 8:30am and worked through to about 6pm. After two weeks without hot water, we were so relieved to finally have everything working again. The installation was tidy, professional, and completed to a very high standard. Overall, Daniel was a pleasure to deal with. His respectful manner, expertise, and clear communication made the whole experience smooth and stress‑free. I feel confident relying on him for future work, and I’ll be using him for all my heating and plumbing needs going forward. I’ll also be recommending him to friends and family.
