CP12 Gas Safety for Holiday Lets: A Landlord’s Guide
What a CP12 covers on a short-term let — and how to keep the certificate in step with your changeovers.
If you let a cottage or lodge in Gwynedd, gas appliances need checking by a Gas Safe registered engineer and a landlord record kept on file. Guests keep arriving either way. This is the practical side of CP12 gas safety certificates — not a legal essay for every edge case.
What “CP12” means in practice
CP12 is the everyday name for the landlord gas safety record issued after the check. Agents ask for it. Platforms ask for it. Insurers sometimes ask for it. Your own folder should have the current one before the old one dies.
The visit is not a boiler-service brochure. The engineer identifies the gas appliances on site, checks safe operation, and assesses flues and ventilation as required. You should leave with clear notes if anything needs work before the next arrival.
Why holiday lets make the diary harder
Long tenancies give you one household and a stable calendar. Holiday lets give you cleaners, agents, key-boxes, and Friday changeovers. A certificate that dies mid-August is rarely an appliance failure — it’s a diary gap.
In Caernarfon and Porthmadog, plant rooms are often compact. Flues run through slate and thick stone. Normal here. It just means the visit needs enough time and clear access.

Don’t leave it to the expiry week
Eryri hiking weekends and coastal summers fill calendars quickly. Book annual gas safety renewals before your busiest months.
Several properties? Landlord gas safety packages keep dates staggered and paperwork consistent.
Who gets the PDF?
Say who holds keys, who should receive the certificate, and any key-box codes before the visit. Managing from afar? An agent in Barmouth or Dolgellau can usually meet the engineer or leave proper access instructions.
Problems we see most
- Expired certificate found at changeover — diary, not drama.
- Blocked cupboard — storage against the boiler panel.
- Forgotten outdoor gas point — BBQ or patio supply missing from the list.
- Three inboxes, one PDF — landlord, agent, and platform all expecting different emails.
None of that needs a crisis response. A short prep list fixes most of it.
