What's Included in a Gas Safety Inspection
A gas safety inspection checks that your gas appliances are operating safely and that combustion gases are being discharged correctly. OnSite Contractors & Plumbing helps landlords, letting agents and property owners across London book inspections with a Gas Safe registered engineer from our team.

Gas Pressure Testing
We check gas pressure and appliance operating pressure to identify issues that could affect safe appliance operation.
Flue and Chimney Checks
Our engineers inspect flues and chimneys to ensure combustion gases are being safely discharged from the property.

Gas Safety Checks for All Major Boiler Brands
Our Gas Safe engineers carry out gas safety inspections for a wide range of boiler brands across London. Each appliance is checked according to its type and installation, including the gas supply, combustion, flue, ventilation and safety controls. Whether you need a gas safety certificate for a Vaillant, Ideal, Worcester Bosch, Baxi or other boiler, we can arrange the required inspection and checks.
Vaillant
Vaillant boilers use electronic controls, sensors and safety components that need to operate correctly during a gas safety inspection. Our Gas Safe engineers check the boiler, gas connections, burner operation and flue, while also checking for signs of unsafe operation. Where required, we can complete the relevant gas safety checks and issue the appropriate certificate.
Ideal
Ideal boilers rely on components such as ignition systems, sensors and electronic controls to regulate heating and hot water safely. During an inspection, our Gas Safe engineers assess the appliance, gas supply, combustion and flue arrangement, looking for faults or signs that could affect safe operation. Once the required checks are complete, we can provide the relevant gas safety certificate.
Worcester Bosch
Worcester Bosch boilers have several safety controls that need to work correctly to maintain safe combustion and operation. Our Gas Safe engineers check the appliance, burner, gas supply, flue and surrounding installation as part of the inspection. We can also identify issues that require attention and complete the necessary checks for a gas safety certificate.
Baxi
Baxi boilers can include electronic ignition, sensors and other safety controls that are checked as part of a proper gas safety inspection. Our engineers assess the boiler and its installation, including the gas connections, combustion, flue and ventilation where applicable. If the appliance meets the required safety checks, we can complete the gas safety certificate.
CORGI
CORGI boilers require the same careful safety checks as other gas appliances, including assessment of combustion, gas connections, flueing and overall appliance condition. Our Gas Safe engineers inspect the installation and check that the boiler is operating safely under normal conditions. Any safety concerns can be identified during the inspection before the relevant certificate is completed.
Combi Boilers
Combi boilers provide heating and hot water from a single appliance, so the boiler and its gas components need to be checked as part of the inspection. Our Gas Safe engineers assess the burner, gas supply, flue, controls and appliance condition to identify any safety concerns. We can then complete the required checks and provide a gas safety certificate where applicable.
System Boilers
System boilers work alongside separate heating and hot water components, making it important to assess the boiler and its gas installation together. Our Gas Safe engineers check the appliance, gas connections, combustion and flue, as well as relevant ventilation and safety requirements. Once the inspection is complete, we can provide the appropriate gas safety certificate.
