Powerflushing
Powerflushing removes sludge, rust, and debris that builds up in your central heating system over time. This contamination reduces efficiency, causes cold spots on radiators, increases heating bills, and can lead to boiler breakdowns.
Our professional powerflushing service uses specialized equipment to circulate cleaning chemicals through your system at high velocity, removing years of accumulated debris. The process typically takes 4-6 hours and can dramatically improve system performance.
We recommend powerflushing before new boiler installations, when radiators have cold spots, if the system is noisy or slow to heat, or as part of regular maintenance every 5-7 years. The process extends equipment life and reduces energy consumption.

Future Fuels
Gas boilers are not being banned in 2025, and hydrogen-ready boilers represent an important part of the UK's future heating strategy. These boilers are designed to burn natural gas today while being capable of converting to run on 100% hydrogen when the gas network transitions. Leading manufacturers including Worcester Bosch, Viessmann, and Vaillant already offer ranges of high-efficiency, hydrogen-ready boilers.

EXCELLENT Based on 19 reviews Posted on Gary Clark2026-03-26Trustindex verifies that the original source of the review is Google. I had Stephen and the guys round yesterday fitting me a new boiler and flue, a very quick installation, highly recommend.Posted on David Frost2026-02-27Trustindex verifies that the original source of the review is Google. Great tean of installers, new boiler and thermostat fitted very professional service, kept me up to date with the progress from my appointment to completion. I would definately recommend Gasfix. Well done guys, great service.Posted on Cassy Stanton2026-02-08Trustindex verifies that the original source of the review is Google. We knew of Steve through a relation who he had done work for. When we woke up to no heating or hot water during cold weather, we rang him and he responded straight away. He came that morning and found the fault. He was completely transparent with us and advised that due to the age of our boiler (over 30 years old) and some radiators he could only effect a temporary repair. Advising that the temp repair may last, but most probably not. Knowing we would need a new boiler, we asked Steve for a quote the next day. We were happy with the quote and booked for the work to be done. Steve and his team worked with the least possible disruption. Their workmanship was excellent with all waste being disposed of and there were no hidden extras on the invoice. He then contacted us the day after completion to check all was well. We would highly recommend Steve (Gasfix Heating and Plumbing) and have already asked him to quote to fit a new bathroom for us.Posted on Nikki Jago2026-01-28Trustindex verifies that the original source of the review is Google. Steve and his team truly saved the day. Another plumbing company replaced a part in my boiler, which had been working perfectly apart from an issue with the pressure gauge. After installing the part, they left me with no heating or hot water, as the boiler started producing error messages. The plumber couldn’t explain what the issue was, and I honestly felt like they just weren’t that bothered. Steve from Gasfit came highly recommended and arrived the very next day. He was professional, knowledgeable, and immediately put me at ease—I felt confident he knew exactly what he was doing. Within 10 minutes, he had everything sorted and left me with a fully working boiler. I can finally look forward to a nice hot shower! I would highly recommend Gasfit and will definitely be using them again in the future. Thanks to Steve and the team.Posted on Tony Spink2026-01-14Trustindex verifies that the original source of the review is Google. Fixed heat exchanger for hot water on combi boiler at a great price. Replaced my very old rads in a day. Polite, professional team. Stuck to quote despite some extra pipework needed to install metric sizes. Highly recommended.Posted on A Palmer2025-12-31Trustindex verifies that the original source of the review is Google. My elderly and vulnerable mother’s gas boiler broke down at the worst possible time, during the very cold weather around New Year. Preferring to use a trusted local engineer, I contacted GasFix. Stephen arrived within an hour, diagnosed the problem within minutes, and temporarily got the boiler working so the heating was restored straight away. He then returned the following day to fit the replacement part. Stephen was extremely knowledgeable, professional, and reassuring throughout. I wouldn’t hesitate to recommend GasFix — outstanding service from start to finish.Posted on Peter Hockley2025-03-17Trustindex verifies that the original source of the review is Google. We are very pleased with all the work he has carried out and he is very professional in the work he carries out he is a very honest tradesmen, his advice he gave to me and my wife was to point on the pros and cons of what and in the end would cost more so a big thank you guy'sPosted on Angela Issel2024-12-18Trustindex verifies that the original source of the review is Google.

Fitted a new Baxi boiler, came to look at old boiler the same day we called and within two days had the new one installed, fast and professional, clean installation and cleaned and tidied up after themselves, they checked their work before leaving and set up the wireless thermostat without me having to ask, 5* service would absolutely recommend and will definitely be using again in the future!
