What Is a Landlord Gas Safety Certificate?
If you rent out a property with gas appliances, a landlord gas safety certificate — officially known as a CP12 certificate — is not optional. It is a legal requirement under the Gas Safety (Installation and Use) Regulations 1998. Failing to hold a valid certificate can result in fines of up to £6,000 per offence, invalidation of your landlord insurance, and — most critically — real danger to your tenants.
At Cathedral Gas Services, we carry out hundreds of landlord gas safety checks across Coventry and the wider West Midlands every year. This guide covers everything you need to know: what the CP12 certificate includes, how often you need one, what the law says, and how to book your annual gas inspection quickly and affordably.
Our Gas Safe registered engineers offer same-week appointments across Coventry and the West Midlands.
What Does a Gas Safety Check on a Rental Property Include?
A gas safety check for a rental property is a thorough inspection of every gas appliance, fitting, and flue within the property. It must be performed by a Gas Safe registered engineer — no exceptions. During the annual gas inspection, the engineer will:
Once the inspection is complete, the engineer issues the CP12 certificate, which records the results for each appliance, the date of inspection, and the engineer’s Gas Safe registration number. If any appliance is found to be immediately dangerous (ID) or at risk (AR), it will be disconnected and cannot be used until repaired by a qualified engineer.
Legal Requirements for Landlords: Gas Safety
The legal requirements for landlord gas safety are set out clearly in UK law, and ignorance is not a defence. Here is what you are obligated to do as a landlord:
You must arrange an annual gas inspection of all gas appliances and flues in your rental property. The check must be carried out by a Gas Safe registered engineer, and a new CP12 certificate must be issued every 12 months. You cannot simply renew the existing certificate — a fresh inspection is required each time.
You are legally required to give your tenants a copy of the gas safety record within 28 days of the inspection being completed. For new tenants, the certificate must be provided before they move in. Keeping records for at least two years is also a statutory obligation.
Beyond the annual inspection, you have an ongoing duty to ensure all gas appliances, flues, and associated pipework are maintained in a safe condition throughout the tenancy. This means responding promptly to reported faults and scheduling repairs through qualified engineers.
Since 1 October 2022, landlords in England are required to fit a carbon monoxide alarm in any room with a fixed combustion appliance — which includes gas boilers. While this is separate from the CP12 certificate, our engineers can check your alarms are properly installed during your annual gas safety check.
Our team can advise on all aspects of landlord gas safety in Coventry and ensure your property meets every legal requirement.
How Often Do You Need a Landlord Gas Safety Certificate?
The CP12 certificate must be renewed every 12 months without exception. There is no ‘grace period’ built into the law — if your certificate expires and something goes wrong, you are personally liable. Many landlords set up a standing reminder with their letting agent or directly with their gas engineer to ensure the annual gas inspection never lapses.
A useful tip: if your current certificate has fewer than two months left to run, you can book the next inspection early without losing any time from your renewal date. Your new certificate will simply be dated 12 months from the expiry of the old one, not from the early inspection date.
Why Coventry Landlords Choose Cathedral Gas Services
As a Coventry-based gas safety specialist, Cathedral Gas Services understands the pressures that local landlords face — tight turnarounds between tenancies, remote management, and the ever-present risk of non-compliance. That’s why we’ve built our service around making the landlord gas safety certificate process as seamless as possible.
What Happens if You Don’t Have a Valid CP12 Certificate?
The consequences of failing to hold a current landlord gas safety certificate in Coventry — or anywhere in the UK — are severe. The Health and Safety Executive (HSE) actively enforces gas safety regulations, and landlords found to be non-compliant face:
Beyond legal consequences, the human cost of gas incidents cannot be overstated. Carbon monoxide poisoning is often called the ‘silent killer’ because it is odourless and invisible. An annual gas inspection is a small investment that can genuinely save lives.

No. A landlord gas safety certificate can only be issued by a Gas Safe registered engineer. It is illegal for an unregistered person to carry out gas work on a property. Always check your engineer's credentials on the Gas Safe Register website before booking.
A CP12 (gas safety check) is a legal requirement that checks all gas appliances for safe operation. A boiler service is a more detailed maintenance procedure that cleans and services the internal components of the boiler. Both are recommended annually, but they are separate tasks. Cathedral Gas Services can carry out both in a single visit to save you time and cost.
If an appliance is found to be immediately dangerous (ID), the engineer is legally required to disconnect it. If it is 'at risk' (AR), you will be advised to have it repaired before further use. The CP12 certificate will still be issued, but the failed appliance will be clearly noted. We can advise on repair or replacement options for any appliances that don't pass.
If the property has any gas appliances — including a gas hob, fire, or meter — a gas safety check is required. If the property is entirely electric with no gas supply, you do not need a CP12 certificate. However, you should still ensure electrical safety certification is in order. If you're unsure, our team can advise during a quick consultation.
Don’t wait until your boiler fails. Our Gas Safe registered engineers provide professional power flush services with honest advice and competitive pricing.
