Old boiler worth replacing?
There's no fixed age at which a boiler must go. The sensible test is repair frequency, parts availability and how it's performing versus a modern condensing unit.
- Gas work only goes to installers who give us a Gas Safe number
- Never more than three local firms on your job
- Free to use, with no obligation to go ahead

Check these first
- How many repairs in the last two years, and what did they cost in total?
- Are parts still available from the manufacturer for that model?
- Is it a non-condensing or back-boiler unit? Replacements are usually a bigger job.
- Would you also change fuel, boiler type or position? That changes the quote a lot.
What happens next
Ask installers to quote like-for-like as well as any upgrade option, so you can compare on the same basis. Only a survey can confirm what your home needs.
What we require of installers
Gas Safe registration
Each installer gives us their Gas Safe registration number when they join. We do not check every installer on the official Gas Safe Register ourselves, so please ask to see the engineer's Gas Safe ID card and check them at gassaferegister.co.uk before work starts. A listing on BoilerMatch UK is not an endorsement or guarantee of any installer's work. Oil and electric boilers follow their own competent person routes, so ask which applies to your job.
Building regulations
Boiler work in England and Wales needs to meet Approved Documents J and L and be notified properly. Scotland and Northern Ireland have their own equivalents.
Benchmark handover
Ask for the Benchmark checklist to be filled in on the day, because most manufacturers need it before a warranty will stand.
Accreditations we look for
- GAS SAFEGas work
- TRUSTMARKQuality scheme
- OFTECOil heating
- NICEICElectrical
- NAPITElectrical
- CIPHEPlumbing body
We ask installers to hold the registration that fits the job, such as Gas Safe for gas and LPG, OFTEC for oil, and an electrical competent person scheme for electric. BoilerMatch UK is not the Gas Safe Register and is not accredited or endorsed by any of these organisations, so it is always worth checking an installer's own registration before work starts.
Up to 3 local quotes. No obligation.
Other situations
Boiler quotes by city
BoilerMatch UK introduces homeowners to local heating installers and you decide who, if anyone, you hire. We are not the Gas Safe Register, we do not fit or repair boilers ourselves, and any quote, work or warranty is agreed directly between you and the installer.
