Arrange a Gas Safety Certificate (CP12) for your Caernarfon rental without the ring-around: we confirm price and availability, the certificate arrives digitally, and the renewal date is tracked for you.
Straight answer
If you let a property with gas appliances in Caernarfon, the law requires a gas safety check every 12 months, carried out by a Gas Safe registered engineer. The record it produces — the CP12 — goes to your current tenants within 28 days, and to new tenants before they move in.
Booking
How it works
We're building coverage in Caernarfon through our national onboarding programme, and we won't pretend otherwise with a fake availability calendar. Send the property details and we'll confirm by email whether we can cover the job, and the price, before anything is committed.
The local picture
Letting in Caernarfon: the practical points
The gas rules themselves are national, so nothing about the check is different in Caernarfon — what's local is the housing enforcement around it. Cyngor Gwynedd is the housing authority for the area, and if your property needs an HMO licence, the current gas record is the kind of document its conditions will expect you to hold and produce on request.
Credentials
Who you're letting in
Gas work is one of the few trades where the register isn't optional: an engineer who isn't Gas Safe registered can't legally sign your record, full stop. We check registration and insurance before confirming any booking, and you can verify any engineer yourself on the public Gas Safe Register — ask to see the ID card, and check the back for the work categories it covers.
Pricing
What a CP12 costs
Two identical adverts can hide very different jobs — one boiler versus four appliances, ground-floor flat versus awkward loft access. That's why we show a guidance range rather than a headline teaser price, and confirm the real figure for your property before you commit. Bundling the annual boiler service into the same visit typically works out cheaper than booking it separately.
The inspection
What the engineer actually checks
The engineer starts at the meter, checking the gas tightness of the whole installation, then works through each appliance: the boiler, any gas fire or hob you supply, and the flues that serve them. Operating pressure, combustion performance, ventilation and flame supervision are all tested; the flue check confirms combustion products actually leave the building. Anything unsafe is classified on the spot, and the visit ends with the record itself — every appliance listed, every result written down.
The law
Your legal duty, in plain English
The Gas Safety (Installation and Use) Regulations 1998 make the annual check a hard legal duty wherever in the UK you let, Caernarfon included. The HSE prosecutes failures — penalties are unlimited fines and potentially imprisonment — and in England an expired record blocks a valid Section 21 notice. If the property is a licensed HMO, expect Cyngor Gwynedd to require the current record as a licence condition too.
Landlords must have every gas appliance and flue they provide checked by a Gas Safe registered engineer at least every 12 months, keep the record for two years, give tenants a copy within 28 days of the check, and give new tenants a copy before they move in.
Equivalent annual duty applies in Northern Ireland; engineers must be Gas Safe registered.
Penalties stated are statutory maximums or court-set; Cyngor Gwynedd is the local housing authority for Caernarfon.
FAQ
Common questions about the Landlord Gas Safety Record (commonly called a CP12)
What does the gas safety record actually include?
It lists each appliance and flue checked, the checks performed, defects found and action taken, the engineer's name, registration number and signature, the property and landlord details, and the date of the check.
How often does a landlord need a gas safety check?
Every 12 months. You can arrange the renewal check any time in the two months before the current record expires and keep the original expiry date — the MOT-style rule — so booking early never shortens your certificate.
What if an appliance fails the gas safety check?
The engineer records the defect and classifies how dangerous it is. Immediately dangerous appliances may be disconnected with your permission. You must have faults fixed by a Gas Safe engineer before the appliance is used again; the record itself lists the defects found.
What is a CP12 gas safety certificate?
CP12 is the industry nickname for the Landlord Gas Safety Record — the document a Gas Safe registered engineer issues after checking each gas appliance, flue and pipework in a rental property. Landlords letting property in Caernarfon must have this check done every 12 months.
Do I have to give tenants a copy of the gas safety record?
Yes. Existing tenants must receive a copy within 28 days of the check, and new tenants must get one before they move in. For rental periods under 28 days, displaying a copy in the property is acceptable.
