What the warranty covers
A manufacturer warranty covers faults with the boiler itself for a set period — anywhere from 2 to 10+ years depending on the brand and whether it was fitted by an accredited installer. It doesn’t cover general wear items or problems caused by a dirty system.
Keeping it valid: the annual service
Nearly every warranty requires a documented annual service by a Gas Safe engineer. Miss one and the manufacturer can decline a claim — so the service isn’t just good practice, it’s what protects the cover.
Registration
The boiler must usually be registered with the manufacturer within a set window after installation. We handle registration as part of the job, so your warranty starts cleanly.
What voids a warranty
Common culprits: skipping the annual service, installation by a non-accredited fitter, or running the boiler on a dirty, un-flushed system. Keep the services up and the paperwork safe, and you’re covered.
