About this service
Boiler Repairs in South West London, done properly the first time
A boiler that won't fire, locks out on a fault code, or heats water but not the radiators — most of these come down to a short list of causes, and our engineers carry the common parts (pumps, diverter valves, PCBs, sensors) for the brands we see most, so most repairs are done on the first visit rather than turning into a two-appointment job.
Age matters when deciding whether to repair or replace. Under 8 years old, almost always worth fixing. Past 12-15, if it's a major component failure, we'll tell you honestly when the money's better spent on a replacement.

Frequently asked
Your questions, answered
Should I repair or replace my boiler?
Under 8 years, repair. Over 12-15 with a major fault, replacement is usually the smarter spend — we'll price both and give you a straight recommendation.
Can I repair my own gas boiler?
No — it's illegal for anyone not on the Gas Safe Register to work on gas appliances, and it will invalidate your home insurance. Bleeding a radiator or topping up pressure via the filling loop is fine to do yourself.
Are your boiler repairs engineers Gas Safe registered?
Yes — every engineer working on boiler repairs in South West London is Gas Safe registered, manufacturer-trained and fully insured to £5m public liability. We'll show our ID on arrival.
