CP14 is the trade name for the Warning/Advice Notice a Gas Safe registered engineer issues when a gas appliance, flue or installation is found to be Immediately Dangerous (ID) or At Risk (AR). It is not a separate job in its own right — it is the record an engineer produces on the spot when a routine visit (most often a CP12 landlord safety check, but any gas work can turn one up) finds something unsafe.
A third classification, Not to Current Standards (NCS), is different in kind: NCS is a recommendation that an installation no longer meets current standards even though it isn't unsafe. It is noted on the record of the visit itself (for example the CP12) rather than triggering its own warning notice — only ID and AR findings are recorded on a CP14.
This describes the two classifications a CP14 covers, as public trade practice. Whether a specific finding on a specific installation is ID, AR or NCS is a judgement for the attending Gas Safe registered engineer, not something this page can determine.
The engineer asks the customer, tenant or responsible person on site to sign the CP14 to confirm they've received the notice and understood what it says. The signature confirms receipt, not agreement with the finding — and it isn't a condition of the finding standing. If someone declines to sign, the engineer records that refusal on the notice itself; the classification and whatever action was already taken (an ID appliance is made safe regardless) don't depend on a signature being obtained. What happens next at a specific property — whether the gas supplier or emergency services need notifying, what remedial work is required — is a matter for the attending engineer and outside what this page can advise on.
NexCert issues the CP14 (Warning/Advice Notice) alongside the CP12 landlord gas safety record and the other three gas certificate types it ships under GSIUR 1998: CP2 (domestic gas service record), CP17 (commercial gas installation safety report) and CP42 (commercial catering gas safety certificate). Because CP14 is issued from the same workspace as the visit that found the fault, an engineer working through a CP12 (or any other gas job) on a phone or tablet doesn't need to switch to a separate pad or app when a finding needs recording — the notice is completed on site, the customer's signature (or their recorded refusal) captured there, and the finished notice delivered with an evidence trail alongside the original job.
There are fields for your own Gas Safe registration number, at both company and individual engineer level, on every certificate NexCert issues.
Most CP14s are issued during a CP12 landlord gas safety visit — see CP12 software for the annual landlord gas safety record for the certificate that most often leads to one. The same applies on a CP2 domestic service visit, or a CP17/CP42 commercial visit: any gas job can turn up an ID or AR finding, and NexCert issues the notice from whichever job it comes from rather than treating it as a separate piece of software.
/ FAQ
Immediately Dangerous means an immediate risk to life or property — the appliance or installation is made safe on the spot and can't be used again until repaired. At Risk is a risk that isn't immediate; whether the installation stays in use pending repair is the attending engineer's judgement.
No. NCS is recorded on the visit's own record (for example the CP12) rather than on a separate warning notice; only ID and AR findings get a CP14.
They're asked to sign to confirm they've received and understood the notice. A refusal to sign is recorded on the notice; it doesn't undo the finding or the action already taken on an Immediately Dangerous appliance.
Yes — "CP14," "warning notice" and "advice notice" all refer to the same document in ordinary trade use, covering both Immediately Dangerous and At Risk findings.
