Landlord Gas Safety Certificate — sorted in 48 hours
Every UK rental with any gas appliance needs an annual Landlord Gas Safety Certificate (technically called a CP12). From £60 + £10 per gas appliance, issued by Gas Safe registered engineers, stored in your digital vault.
What is a Landlord Gas Safety Certificate?
A Landlord Gas Safety Certificate is the document a Gas Safe registered engineer issues after they've inspected every gas appliance, pipe and flue in your rental property. Its formal name is a CP12 — Landlord Gas Safety Record.
Under the Gas Safety (Installation and Use) Regulations 1998, every landlord in the UK must hold a current Gas Safety Certificate, renewed at least every 12 months, for any rental property fitted with a gas appliance. You then have 28 days to give a copy to existing tenants — and must hand a copy to any new tenant before they move in.
Who needs one?
- Every private rental in the UK that has any gas appliance — boiler, hob, gas fire, immersion or even a disconnected one still on the supply.
- HMOs and multi-let properties — with one CP12 per unit and shared appliances inspected separately.
- Properties you own under a limited company.
- Holiday lets, short-term lets and Airbnb properties that fall under the Regulations.
An all-electric property doesn't need a CP12. Owner-occupiers don't need one either — only landlords face the legal duty.
What's actually checked?
A Gas Safe registered engineer will:
- Visually inspect every gas appliance for safe operation, stable flame and signs of incomplete combustion.
- Test gas tightness on the supply pipework — the "tightness test".
- Check ventilation and air supply to each appliance.
- Inspect flues and chimneys for correct operation and proper sealing.
- Confirm operating pressures and heat input where measurable.
- Verify a working CO alarm in every room with a fixed combustion appliance (a legal requirement since 1 October 2022).
- Issue the CP12 — one copy for you, one for the tenant, one for our records.
What happens if I don't have one?
The Gas Safety (Installation and Use) Regulations are enforced by the Health and Safety Executive and carry serious penalties:
- HSE fines from £6,000 per appliance, per breach. Repeat or serious cases can attract unlimited fines and prosecution under criminal law.
- An invalid Section 21. You cannot legally end an assured shorthold tenancy without a valid CP12 on file at the start of the tenancy.
- Voided buildings insurance. Most landlord policies require a current CP12; without one, a claim after a gas leak, fire or explosion may be refused.
- Mortgage covenant breach. Buy-to-let lenders almost universally require compliance with letting regulations.
- Manslaughter charges in the worst cases involving carbon monoxide deaths — landlords have been jailed.
How much does a Landlord Gas Safety Certificate cost?
GetCerted prices the Landlord Gas Safety Certificate at a flat £60 plus £10 per gas appliance. So a typical 1–3 bed Fylde rental with a combi boiler and a gas hob lands at £80; a property with three appliances sits at £90. Everything's quoted up front, fixed before the engineer arrives. Read our full Gas Safety Certificate cost guide.
How long does it take?
A standard inspection on a 1–3 bed rental takes around 30–60 minutes. You'll have your Landlord Gas Safety Certificate as a PDF in your GetCerted vault the same evening — shareable with tenants, agents and lenders in one click.
How often do I need to renew it?
Every 12 months, with no exceptions. Best practice is to book the new inspection 4–6 weeks before the existing certificate expires — that gives you a buffer if the engineer finds a fault that needs a repair and a re-test. If you renew before expiry, the new 12-month clock starts from the old expiry date, so you don't lose any time.
Can I combine the inspection with a boiler service?
Yes — and we recommend it. A gas safety check confirms the appliance is safe; a boiler service goes further and keeps it efficient. Bundling the two means one visit, one tenant access window, and a cheaper overall bill than booking each separately.
