CP2 is the trade name for a Domestic Gas Service Record — the record of a routine annual service on a gas appliance (most commonly a boiler). Unlike CP12, a CP2 is not a statutory requirement under GSIUR 1998. GSIUR requires the annual landlord safety check (recorded as a CP12) on rented property; it does not require an owner-occupier, or a landlord beyond the CP12 check itself, to have appliances serviced annually. A CP2 is done because a manufacturer's warranty requires proof of an annual service to remain valid, an insurer's policy terms ask for it, or a homeowner or landlord simply wants a maintained service history for the appliance.
The two are easy to conflate because both come out of an annual visit by the same engineer, but they answer different questions:
A landlord property can have both a current CP12 and a current CP2 for the same boiler, issued on the same visit, recording two different things.
This describes the distinction between the two documents as public trade practice. Whether a specific warranty or insurance policy requires a CP2, and on what schedule, is a matter for the manufacturer's or insurer's own terms, not something this page can determine.
NexCert issues the CP2 (Domestic Gas Service Record) alongside the other four gas certificate types it ships under GSIUR 1998: CP12 (landlord gas safety record), CP14 (Warning/Advice Notice), CP17 (commercial gas installation safety report) and CP42 (commercial catering gas safety certificate). Where the same visit produces both a CP12 and a CP2 — common when a landlord's annual safety check and the boiler's annual service happen together — both are completed from the same job on a phone or tablet, on site, and delivered together with an evidence trail rather than as two separate pieces of paperwork.
There are fields for your own Gas Safe registration number, at both company and individual engineer level, on every certificate NexCert issues.
A CP2 service visit can turn up an Immediately Dangerous or At Risk finding just as a CP12 visit can. Where that happens, it's recorded on a CP14 Warning/Advice Notice rather than on the CP2 itself — see CP14 software for the gas Warning/Advice Notice.
/ FAQ
No. GSIUR 1998 requires the annual landlord gas safety check (CP12) on rented property. A CP2 service record is not a statutory document — it exists because a manufacturer's warranty, an insurer, or the property owner wants proof of an annual appliance service.
A CP12 records whether a landlord's gas appliances, flues and pipework are safe, and is statutory for rented property. A CP2 records that an appliance was serviced and what was found, is not statutory, and applies to owner-occupied property too.
Yes — where a landlord's annual safety check and the boiler's annual service happen on the same visit, both records can be completed from that one job.
