Comprehensive Gas Safety Certificates (CP12)
A Gas Safety Certificate (CP12) is a legal requirement for all rental properties with gas appliances, including boilers and cookers. Our inspection ensures all appliances are safe, efficient, and fully compliant.
We check boilers, cookers, and hobs, making sure your entire gas system is tested and certified.
All landlords in the UK are legally required to obtain a valid Gas Safety Certificate (CP12) every 12 months to ensure all gas appliances are safe and compliant.

What’s Included in a Gas Safety Inspection?
Appliance Checks
Each gas appliance is inspected to ensure it is correctly installed, properly adjusted, and burning gas safely. We carry out these checks for properties throughout Surrey and London to ensure full compliance.
Ventilation Verification
Proper ventilation is essential for safe operation. All air vents and airflow routes are checked to ensure they are clear and functioning correctly in line with UK safety standards.
Flue and Chimney Testing
Flues and chimneys are tested to confirm that harmful gases are safely removed from the property and discharged externally, ensuring safety for properties across Surrey and London.
Safety Device Inspection
All safety devices are tested to ensure they are working correctly and will respond in case of a fault, helping landlords meet legal obligations.
Gas Leak Checks
The entire system is checked for gas leaks to ensure there are no risks to occupants or the property.
What if the engineer identifies any problem with the boiler?
All Gas Safe registered engineers must follow the Gas Industry Unsafe Situations Procedure when identifying safety risks. If an issue is found, the engineer assesses the hazard, labels it appropriately, and takes action to keep the property safe and compliant. After major repairs or alterations, a new Gas Safety Certificate (CP12) is issued to confirm continued safety.
