For landlords in London, gas safety is not just good practice. It is an essential part of responsible property management. Annual gas safety checks help protect tenants, reduce risk, and support legal compliance for rented properties.
At Trava GAS, we provide professional Landlord Gas Safety Certificates (CP12) and gas inspections across London, helping landlords stay compliant with confidence.
What is a Gas Safety Certificate?
A Gas Safety Certificate, often called a CP12, is a document issued after a qualified Gas Safe registered engineer checks the gas appliances, fittings, and flues in a property. The certificate confirms whether these items are operating safely at the time of inspection.
Why landlords need one every year
Annual gas safety checks are important because gas appliances can develop faults over time. Boilers, cookers, pipework, and flues all need regular inspection to ensure they are working safely and efficiently.
For landlords, an annual inspection helps to:
- Protect tenants from gas-related risks
- Identify faults early
- Keep heating systems in safe working condition
- Show professional responsibility
- Avoid last-minute compliance stress
What is checked during the inspection?
During a landlord gas safety inspection, a Gas Safe engineer may check:
- The boiler and gas appliances
- Ventilation and air supply
- Pipework condition
- Flue performance
- Safe combustion
- Signs of leaks or unsafe operation
If any issues are found, the engineer can explain the next steps and recommend repairs if needed.

Why regular checks matter for landlords
A rental property should be safe, reliable, and properly maintained. An annual gas safety check gives landlords peace of mind while helping tenants feel secure in the property they live in.
Regular checks can also help reduce unexpected breakdowns and spot maintenance needs before they turn into bigger problems.
