Gas Safety Certificates (CP12)

A Landlord Gas Safety Record (CP12) is a legal requirement for any rental property with gas appliances. Valid for 12 months, this must be renewed annually by a Gas Safe registered engineer to ensure tenant safety.

Landlord Legal Responsibilities

Under the Gas Safety (Installation and Use) Regulations 1998, landlords are legally responsible for the safety of gas pipework, boilers, and flues. Our specialist inspections are performed by fully qualified engineers, ensuring your property remains legally compliant and insurance-valid.

Annual Cycle:
Renewal Due

28-Day Rule

Landlords must provide a copy of the CP12 to existing tenants within 28 days of the check and to new tenants before they occupy the property.

Criminal Penalties

Non-compliance is a criminal offence. It can lead to unlimited fines, imprisonment, and the total invalidation of your landlord insurance policy.

Carbon Monoxide Safety

Gas engineers perform rigorous tightness testing and flue analysis. Regular CP12 inspections are the primary line of defence against Carbon Monoxide poisoning, identifying potential leaks or combustion issues before they become life-threatening.

The Gas Safety Inspection Process

Gas Safe Registered Engineers | Flue Gas Analysis | Tightness Testing

Appliance Testing Thorough checking of boilers, hobs, and fires to ensure they are burning at the correct pressure and safety.
Flue Flow Checking the extraction of combustion products and ensuring there are no blockages or leaks in the flue system.
Ventilation Check Verifying that appliances have a sufficient permanent air supply for safe, complete combustion.
Pipework Integrity Full tightness test from the meter to ensure there are no gas leaks within the property's pipework.
Compliance Check

Have you checked your records?

Check if you already have a Gas Safety Certificate or CP12.

Before booking a new inspection, it is worth checking your existing property documents to see if a valid Landlord Gas Safety Record (CP12) is already in place. These certificates must be renewed every 12 months for rental properties.

Ensuring you have a valid record can save you from paying for a new report unnecessarily. If you still require a new inspection, you can book online with us.

Frequently Asked Questions

Q: How long does a Gas Safety Certificate inspection take?

A Gas Safety Certificate inspection typically takes between 30 minutes to an hour, depending on the complexity of the property and the number of gas appliances that need to be checked. Larger properties or those with multiple gas appliances may take a little longer.

Q: Do I need to be present during the Gas Safety Certificate inspection?

It’s not required for you to be present during the inspection, but it can be helpful if you’re available to provide access to gas appliances, such as boilers, ovens, and gas meters. The inspector will need to check these systems for safety.

Q: Is a Gas Safety Certificate required for rental properties?

Yes, landlords must ensure that all gas appliances in a rental property are inspected and have a valid Gas Safety Certificate every year. This certificate must be provided to tenants at the start of the tenancy and upon renewal of the certificate.

Q: What happens if my Gas Safety Certificate inspection reveals a problem?

If the inspection reveals any safety concerns or issues, the engineer will provide a report with details of the problems and may advise on necessary repairs or improvements. In the case of a serious safety issue, the appliance may need to be disconnected until it is properly repaired.
