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.
