A landlord gas safety check, often called a CP12, is a legal requirement for any rented property with gas appliances. It must be carried out by a Gas Safe registered engineer to ensure that all appliances and flues are safe for tenants to use.
Gas appliances inspection:
All gas appliances—such as boilers, stoves, ovens, water heaters and fireplaces—are inspected for signs of damage, wear or malfunction that could pose safety risks.
Flue inspection:
The engineer checks that flues and ventilation systems are correctly installed, unobstructed and ventilating safely. Proper ventilation is essential for removing combustion gases like carbon monoxide.
Gas pressure and flow test:
Tests are carried out to ensure gas pressure and flow rates are within safe, manufacturer-recommended limits.
Combustion analysis:
For flued appliances (such as boilers), the engineer may carry out combustion tests to confirm efficient burning and safe levels of gases being released.
Gas safety record (CP12):
A Gas Safety Certificate is issued after the inspection. This must be given to tenants within 28 days and always before a new tenant moves in.
Repair recommendations:
If the engineer identifies any defects or safety concerns, they will outline recommended repairs. Landlords must arrange these promptly to maintain compliance and safety.
Record-keeping:
Landlords must keep CP12 certificates and gas safety check records for at least two years as proof of compliance.
A typical landlord gas safety check usually takes between 30 minutes and 1 hour. The exact duration depends on the number of appliances, how accessible they are, and whether any issues are discovered during the inspection.
Property Details:
The full address of the rental property where the inspection took place.
Landlord Information:
The landlord or property owner's name and contact details.
Engineer Details:
The Gas Safe engineer's name, registration number and contact information, confirming their accreditation.
Gas Appliances Checked:
A list of all gas appliances inspected—such as boilers, ovens, stoves, water heaters and fireplaces.
Safety Status:
Each appliance is marked as passed or failed. Any defects and recommended remedial actions are also recorded.
Date of Inspection:
The exact date the gas safety check was carried out.
Signature:
The Gas Safe engineer signs the certificate to confirm the inspection complies with regulations.
Validity Period:
The certificate is valid for 12 months. Landlords must issue an updated CP12 every year and provide it to tenants within the required timeframe.
A CP12 certificate, also known as a Gas Safety Certificate, is an official document issued to landlords after a qualified Gas Safe engineer has completed a gas safety check on a rental property. It confirms whether the appliances and flues are safe for tenants to use.
Landlords are legally required to have gas safety checks carried out every 12 months on all gas appliances and flues within their rental properties. This includes boilers, gas cookers, water heaters and fireplaces.
