Guarantee support

Why service records matter for a manufacturer guarantee

Most extended manufacturer guarantees on new boilers are conditional on annual servicing, and it is the homeowner's responsibility to keep evidence that each service happened.

What we check first with service records supporting a guarantee

The record does not need to be elaborate: a dated invoice or service report naming the engineer and the work carried out is normally sufficient. Manufacturers can ask for this evidence if a warranty claim is made, and a gap in the record, particularly around the anniversary date, can weaken or void a claim even where the fault itself is unrelated to the missed service.

Get service records supporting a guarantee looked at properly

The honest position: A folder of dated service paperwork is a small habit that can make the difference at claim time if something later goes wrong.

Include the appliance make and model in your enquiry so the correct technical information can be checked.

Questions we get asked

What counts as valid proof of service?
A dated document from a Gas Safe or OFTEC registered engineer describing the work is normally what manufacturers ask for.
What if I lose a service record?
Contact whoever carried out the service, since many engineers keep their own records and can reissue a copy for your file.
