Everything you need to know about professional Gas Safety Certificates for properties across all London boroughs.
A Gas Safety Certificate, or CP12, is the official record issued after a comprehensive safety inspection of your gas appliances. It proves your boiler, pipework, and flues comply with current UK safety regulations.
Landlords are legally obligated to have gas appliances inspected annually by a Gas Safe registered engineer. Homeowners in London are also encouraged to maintain this cycle to ensure optimal efficiency and insurance compliance.
Ensuring that gas appliances are properly ventilated and free from leaks is a critical safety measure. Failure to comply can lead to dangerous carbon monoxide leaks and severe legal consequences for property owners.
First Certify coordinates with a trusted network of local professionals. Every engineer we dispatch across London is Gas Safe registered, fully insured, and highly experienced in local property requirements.
All inspections follow rigorous safety protocols, ensuring your certificate is fully recognised by local authorities, letting agents, and property insurance providers throughout the capital.

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.
