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

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.
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.
