What is a gas appliance inspection?
A gas appliance inspection checks that an appliance, its pipework and its flue are safe — covering combustion, ventilation, flue performance and the condition of the installation.

</figure>Flue and ventilation are the parts that cause harm. An appliance can burn cleanly and still be dangerous if what it produces is not getting out or if the air it needs is not getting in.
Classifications for unsafe situations exist and mean specific things about whether an appliance may continue in use. Those outcomes need recording and acting on rather than treating the certificate as the end of it.
Ventilation is the one that changes without anyone touching the appliance — a blocked air brick or a new partition can make a safe installation unsafe.
In practice
An engineer attending with a registration the FM team has never checked.
He is competent and the card is genuine. His registration category may or may not cover the appliance type in a commercial kitchen.
Registration is by category, and a domestic registration does not cover commercial catering work however capable the individual is.
The check is against the register, and it is about scope as much as validity.
What goes wrong in practice
- Ventilation changed by building work with no reassessment.
- Unsafe classifications recorded and the appliance left in use.
- Flue routes in voids never inspected because access is difficult.
