Gas boiler repair
A gas boiler that has locked out, is losing pressure, cycling on and off or making unusual noises usually points to a specific, fixable fault. Our Gas Safe engineers diagnose and repair combi, system and conventional gas boilers from the leading UK brands.
About this service
What this covers
Gas boiler repair covers everything from a boiler that refuses to fire, to intermittent lockouts, low-pressure faults, noisy operation and hot-water problems on combi units.
We diagnose the actual cause, not just the fault code, using manufacturer service manuals, combustion analysis and pressure testing. Where a repair isn't cost-effective compared to replacement, we'll say so plainly.
Signs you may need this
- Boiler locks out with an error code (F22, E133, EA, etc.)
- System pressure keeps dropping and needs topping up
- Kettling, banging or whistling from the boiler
- Hot water goes cold mid-shower or runs lukewarm
- Radiators warm but hot water isn't (or vice versa)
- Yellow flame, sooting, or condensate pipe frozen in winter
What's included
- Full diagnostic including fault codes and combustion check
- Written explanation of the fault and repair options
- Genuine manufacturer replacement parts where possible
- Pressure and tightness test on completion
- Advice on preventing the same fault recurring
