What great engineers
What great engineers, so friendly, so helpful. New boiler fitted in no time. They ran through all the controls with me and left the place spotless. Very happy!
Amazing service and extremely kind!
Exceptional Service from Start to Finish – A Truly Outstanding Team!
I was quite stressed as I had never experienced issues with my boiler before, and needed a new one installed urgently. The same day, Munvir visited and was fantastic. He took his time, thoroughly assessed the situation, took detailed photos, and reassured me with his calm and professional approach. He was incredibly diligent, answered all of my questions, and clearly showed that he genuinely cares about helping customers. His visit gave me a lot of confidence in the process.
By 9:30 AM the next day, I received a clear and competitive quote and made the full payment without hesitation. Dave, the manager, was also very reassuring, confirming that the installation would happen promptly. It’s clear that Dave leads by example and serves as a positive role model for his team.
The following morning at 7:30 AM, James arrived right on time. He was not only punctual but went above and beyond to ensure everything was done correctly. His expertise was evident as he explained each step of the installation process, making sure I was comfortable and informed. James was thorough, detail-oriented, and worked efficiently without compromising quality. He’s clearly a people person, and his friendly demeanor made the entire experience pleasant. It was obvious that James takes great pride in his work and is dedicated to delivering exceptional service.
Overall, I am beyond impressed. In just 72 hours, I had a fully operational boiler installed by a team who truly care about what they do. The level of service was outstanding, and I believe the entire team—Munvir, Dave, and James—deserve a significant pay increase and company-wide recognition for their hard work and dedication.
Thank you so much—you’re all the best!
GREAT SERVICE !!!
GREAT SERVICE !!!
Dave and his team were outstanding for a recent job when a boiler packed up recently. They went the extra mile by turning up in the evening to diagnose the issue and replaced it the following day. Couldn't recommend them highly enough
Great replacement Combi boiler
Dave got my combi boiler replaced at very short notice and worked around our household’s busy schedule - to such a degree that he had his engineer James come at 07:30 on a Sunday to install it and he was the best gas engineer I’ve ever dealt with - unbelievable professional with great knowledge and really went the extra mile. No damage to any tiling either. Would highly recommend
Excellent Boiler Installation and Follow-Up Service
We recently engaged Dave and his team at Gas Works to install a new boiler and also to revamp the shower system in our house so we can use mains water pressure, rather than noisy pumps. James and his team efficiently worked to complete the big job in two days with minimal disruption to our lives. James was also very patient in helping us learn how to use our new boiler, spending several hours working to connect it to the Wifi controls and then showing us how to operate it. After we went to mains water pressure, we noticed a few toilets and a sink in our house were leaking uncontrollably. I got in touch with Dave who quickly ordered new parts for the toilet and sink and sent Mason, his plumber, who worked until all the toilets and sinks in the house were functioning properly. Mason's stick-to-itiveness and ingenuity were impressive. We have some high-end toilets that are hard to access. Mason found creative ways to get around the access issues so we didn't have to remove the bath paneling which would have likely been costly. Very happy with the works from Gas Works London.
Stellar job
Manveer did an excellent job - he fixed my old boiler quickly, I can't thank him enough. Top professional, tidy, polite.
Gasworks London, Valued Customer.
Been using Gasworks London for 12 years. Just into our second combi boiler with them. Installation and service excellent. Had a fault error code today so messaged Dave. Manveer, one of the engineers, was here within the hour and sorted out the problem. Brilliant. Thanks to Dave and the team.
The Great experience from start to finish.
The plumber arrived promptly and was courteous, knowledgeable, and professional. The quality of the work was fantastic. I couldn't have asked for better; thank you.
Boiler Service
I have been using Gasworks for a number of years for boiler services and plumbing. Most recently they serviced our boiler and also helped us with a water emergency in our downstairs bathroom. Dave and the team have always provided a very good service. I wouldn't use anyone else
Excellent service
Helped diagnose and replace a faulty underfloor heating valve. Very fast call out, accurate quote, excellent service (very quick turn around time and completely solved the issue); did a very good job of explaining in simple terms what would be required and how long it would take
Replaced Boiler
We needed some really urgent work on our boiler as stopped working over Christmas. Struggled to find someone at such short notice. Gasworks visited really quickly and problem solved. Thanks for such speedy service.
Seamless execution of new boiler installation a boiler installed and heard of…
I had a boiler installed and heard of Gasworks via a friend. Her strong recommendation was totally borne out by my experience. I was quoted an extortionate amount by British Gas but Gasworks found a sensible solution and great savings. The team were very conscientious, putting down floor coverings and giving me a heads up for switching off water and electricity in good time. They explained their process, consulted me over decisions and were very thoughtful as I was working at home. They also talked me through the controls patiently. I am absolutely delighted at their efficiency over the project and the tidiness of their work. I'd recommend them strongly! The upgraded hardware is well worth the investment. Thank you.
Do not trust Gasworks and David
Unfortunately cant recommend David and his team who left me with several expensive issues to fix after they left! and arrogantly never even apologised or recompensed me!! Firstly they connected the wrong pipes and instead of apologising they blamed the customer and wanted to charge me for putting it right! (lol!??), they burst other pipes in the property causing me £200 of redecoration works to patch up simply and arrogantly said "these things happen" (lol!!??) And a new heating pump they installed failed (Dave didnt care and didnt even leave me a receipt to claim a new one). Disgusting and arrogant tradesman?

Amazing job
Amazing job! I didn’t wait long to replace my new boiler ! Quick reaction!
I’m happy and I really recommend for 100%.
Not great service at all
Really surprised given the other comments here what poor service I’ve had from gasworks London.
Took me ages to get them to commit to an appointment, then they were more than a hour late without calling and letting me know . They serviced the boiler and said work was needed . Despite my chasing I haven’t heard from them again. Given I employed them on a recommendation similar to those below I don’t quite know what to think .
Boiler replacement of PCB
Next day part and replacement of PCB.
Same day response visit too.
100% would recommend.
