Registering your boiler's warranty after installation
A manufacturer's warranty on a new boiler is not automatic simply by having it installed — most require formal registration, often within a limited window after commissioning, using details specific to that installation. Missing this step can affect your cover.

What matters most with warranty registration
- Most manufacturers require formal warranty registration after installation
- Registration windows are often time-limited from the commissioning date
- Serial number and installer details are needed to complete registration
- Some manufacturers extend warranty length for accredited installer work
- Confirmation of registration should be kept alongside other paperwork
What we check first with warranty registration
Registration is typically completed online through the manufacturer's own system, using the appliance's serial number, installation date and the registered installer's details from the Gas Safe or OFTEC record. Some manufacturers extend warranty length depending on whether an accredited installer completed the work, so registration also confirms this eligibility.
Scope of work
- Domestic boiler installation
- Boiler servicing
