The Law on Gas Safety for Landlords
If you rent out a property in the UK, you have a strict legal duty under the Gas Safety (Installation and Use) Regulations 1998 to ensure that all gas appliances, fittings, and flues provided for tenants are safe.
To prove this, you must obtain an annual Gas Safety Certificate, commonly known as a CP12, carried out by a registered Gas Safe engineer.
What Does a Gas Safety Check Include?
During the annual inspection, our Gas Safe registered engineers will perform a comprehensive series of tests on your property's gas system:
- Appliance Checks: Inspecting all gas appliances (boilers, ovens, hobs, gas fires) to ensure they are burning gas correctly and operating at the right pressure.
- Flue and Chimney Tests: Checking that harmful gases (like carbon monoxide) are being safely discharged outside the property.
- Ventilation Checks: Ensuring there is adequate air supply for the appliances to burn gas safely.
- Safety Device Testing: Verifying that all safety mechanisms built into the appliances are fully functional.
- Pipework Inspection: A visual inspection of the gas pipework and a tightness test to ensure there are no gas leaks in the system.
Providing the Certificate to Tenants
Once the inspection is complete, you will be issued the CP12 certificate. By law, you must:
- Provide a copy of the new certificate to your existing tenants within 28 days of the check being completed.
- Provide a copy of the current certificate to any new tenants before they move in.
- Keep records of all safety checks for at least two years.
What if an Appliance Fails?
If an appliance fails the safety check, the engineer will record the defect on the CP12. Depending on the severity of the fault, the appliance may be classified as:
- Immediately Dangerous (ID): The appliance will be disconnected and capped off immediately with your permission. It cannot be used until the fault is repaired.
- At Risk (AR): The appliance is turned off and should not be used until the issue is fixed.
- Not to Current Standards (NCS): The appliance is safe, but does not meet modern building regulations. Advice will be given on upgrading.
The Penalties for Non-Compliance
Failing to obtain a valid CP12 is a criminal offence. The Health and Safety Executive (HSE) heavily penalises non-compliant landlords. You could face:
- Unlimited fines (routinely exceeding £20,000).
- Up to 6 months in prison.
- Invalidated building insurance.
- Inability to serve a Section 21 eviction notice to your tenants.

Frequently Asked Questions
How long is a CP12 valid for?
A Gas Safety Certificate is valid for exactly 12 months from the date of the inspection.
Can I renew early without losing time?
Yes. You can have the check carried out up to 2 months before the current certificate expires, and the new certificate will still be post-dated to the old expiry date.
Who is responsible if the tenant owns the appliance?
Landlords are only responsible for the appliances and pipework they provide. However, you are still responsible for the safety of the connecting pipework.
