Gas Appliance Safety Inspection

A gas appliance safety inspection checks that a single gas appliance is operating safely and correctly. It helps identify unsafe combustion, poor flueing, inadequate ventilation, leaks, and other issues that can put people and property at risk. You’ll receive clear findings and practical next steps so you can act quickly and stay compliant where required.

Who this service is for

This inspection suits homeowners who want reassurance, landlords preparing for a tenancy or renewal, and small commercial sites with a specific appliance that needs checking. It’s also useful if you’ve noticed warning signs like sooting, staining around the appliance, pilot issues, unusual smells, or frequent shutdowns.

How the inspection is carried out

The engineer will confirm the appliance type, access requirements, and any recent issues you’ve noticed. They’ll then carry out regulated safety checks and tests, explain what they’re doing in plain terms, and document the outcome. If immediate risks are identified, you’ll be told straight away along with the safest next steps.

What happens after the inspection

You’ll receive a clear summary of results and any actions needed, prioritised by risk and urgency. If remedial work is required, you can choose to arrange repairs, servicing, or further investigation, or use the report to plan works with minimal disruption. If everything is satisfactory, you’ll have written evidence of the check for your records.

Frequently Asked Questions

What appliances can be inspected?
Most individual gas appliances can be inspected, such as boilers, gas fires and cookers. The engineer will confirm suitability based on the appliance type, location and access. If you are unsure, share the make and model when booking.
Is this the same as a landlord Gas Safety Certificate?
Not always. A landlord certificate usually covers all relevant gas appliances and associated pipework in a property and must meet specific legal requirements. A single appliance safety inspection focuses on one appliance, although documentation is still provided.
How long does a gas appliance safety inspection take?
Timing depends on the appliance type, access, and whether any issues are found. Many inspections are completed within an hour, but some take longer if additional testing is needed. You’ll be advised if more time is likely once the appliance is assessed.
What if the appliance fails the inspection?
You’ll be told what the fault is, how serious it is, and what should happen next. If the appliance is unsafe, it may need to be isolated or turned off to protect occupants. You’ll then have clear options for repair, replacement, or further diagnostics.
Can you inspect more than one appliance in the same visit?
Yes, you can book inspections for multiple appliances. This can be useful for properties with a boiler and additional appliances like a cooker or fire. Let us know what appliances you have so the visit can be planned properly.
