Keystone London provides gas safety inspections and CP12 certificates across Chelsea, SW3 and SW10 for landlords, homeowners and managed residential properties.
Our Gas Safe registered engineers inspect the relevant gas appliances and installation, check safe operation and record the results clearly. If an issue is identified, we explain what has been found and what action may be required.
We work across period homes, apartments, rental properties and managed buildings, with each inspection carried out around the actual appliances and layout of the property.
The certificate is the record of the inspection. The important part is the safety check carried out before it is issued.
Relevant appliances are checked for safe operation.
Relevant flue and ventilation arrangements are inspected.
Appliance operation and relevant safety conditions are reviewed.
The results of the gas safety inspection are recorded clearly.
A gas safety inspection looks at the relevant gas appliances and parts of the installation to confirm they are operating safely. The exact checks depend on the property and appliances present, but the inspection focuses on the areas most relevant to safe operation.
Relevant gas appliances are inspected and checked for safe operation as part of the gas safety assessment.
Flue arrangements and ventilation are reviewed where relevant to the appliance and installation.
Appliances are checked to confirm they are operating safely and that there are no obvious signs of unsafe combustion or operation.
Relevant visible parts of the gas installation are reviewed for signs of damage, defects or issues that may need further attention.
If a concern is identified, we explain what has been found and whether further work or investigation may be required.
The results of the inspection are recorded clearly so landlords and property managers have a proper gas safety record for the property.
A CP12 gas safety inspection focuses on the safety of relevant gas appliances and installations. A boiler service is planned maintenance of the boiler itself and involves a different set of checks.

Our gas safety inspections are carried out around the actual property and appliances present, rather than treating every Chelsea home in the same way.
Older Chelsea properties may contain heating systems and gas installations that have been altered or upgraded over many years. Our engineers assess the appliances and relevant installation conditions found at the property.
Boilers and gas appliances in apartments are often installed in kitchens, utility cupboards or other compact spaces. Appropriate access, ventilation and flue arrangements form an important part of the inspection where relevant.
We provide gas safety checks for landlords, letting agents and managed residential properties across SW3 and SW10, with clear documentation following the inspection.
Renovated properties can combine newer boilers and appliances with existing pipework or building infrastructure. We assess the gas appliances in the context of the installation actually present.
If an issue is identified during the inspection, we explain what has been found, how serious it is and what the appropriate next step may be. The certificate records the outcome of the inspection, but any required repair work is discussed separately.

Landlords with relevant gas appliances in rental properties need to arrange appropriate gas safety checks and keep the required records. The exact responsibilities depend on the property and tenancy arrangement.
Landlord gas safety checks are generally required on a regular annual basis. Landlords should make sure inspections are arranged within the appropriate timeframe and that records are retained for the property.
The inspection can include relevant gas appliances, safe operation, flue arrangements, ventilation and other applicable safety conditions. The precise checks depend on the appliances and installation present.
The time required depends on the number and type of gas appliances, their location and access within the property. A property with several appliances may take longer than a simple single-appliance inspection.
