If an appliance isn't safe, the certificate needs to say so, and the responsible person needs a Gas Warning Notice. Mucka joins those two things up so you don't fill the same details in twice.
Marking an appliance unsafe
On a CP12 or a Boiler Service Record, each appliance has a result. Three of them flag a problem, following the Gas Industry Unsafe Situations Procedure:
- Immediately Dangerous (ID): a danger to life or property right now.
- At Risk (AR): one or more recognised faults that could make it dangerous.
- Not to Current Standards (NCS): safe to use, but it wouldn't be installed that way today.
Pick the result, add a note, and a photo if it helps. The certificate's overall outcome updates on its own: an ID or AR appliance makes it a fail, an NCS makes it a pass with defects.
The warning notice draft
When you mark an appliance ID, AR or NCS, a defects panel appears on the certificate with a Draft a Warning Notice button. Tap it and Mucka opens a new Gas Warning Notice already filled in with:
- The unsafe appliances carried across from the certificate.
- Each one's classification (ID, AR or NCS) set from the result you recorded.
- The property, client and date.
You then add the bits only you can confirm: what you did about it (made safe, disconnected, or permission refused), the warning label serial, and whether it's reportable under RIDDOR. Approve and send it the same way as any other certificate.
The two records stay linked. The certificate lists the warning notice's serial, and the warning notice shows which certificate it came from, so the paper trail reads both ways.
Good to know
- Mucka never raises the notice on its own. It prepares the draft from what you recorded; approving and sending are your call.
- One notice can cover several appliances. If more than one failed, they all carry across.
- The certificate is still the certificate. The warning notice sits alongside it, it doesn't replace it.
