Gas Safety Check Checklist | What a CP12 Covers

This is everything a Gas Safe engineer checks and records on your landlord gas safety record. It follows the Gas Safety (Installation and Use) Regulations 1998.

For each gas appliance

Check	What it means
Owner	Whether the landlord or the tenant owns the appliance
Make, model, type and location	Which appliance it is and where it is
Flue type	Room sealed (RS), open flued (OF) or flueless (FL)
Operating pressure or heat input	Proof the appliance is burning the right amount of gas
Safety device correct operation	Flame failure devices and other safety controls work
Ventilation adequate	The appliance gets the air it needs to burn safely
Flue flow test	Fumes go up and out of the flue
Spillage test	Fumes do not spill back into the room (open flued appliances)
Visual condition of flue and termination	The flue is intact and ends in a safe place
Appliance serviced	Whether a service was carried out on the visit
Safe to use	The engineer’s verdict for each appliance
Warning label affixed	Whether an unsafe appliance has been labelled

For the installation

Gas pipework tightness test
Installation mechanically sound
Emergency control valve accessible, correctly positioned and labelled
Gas meter present, and working pressure checked
Protective equipotential bonding

Alarms

Number of smoke alarms, and whether they were tested
Carbon monoxide alarm tested

Defects and actions

Any defect is written down with the action taken. If an appliance is unsafe, the engineer follows the Gas Industry Unsafe Situations Procedure, which may mean turning it off and labelling it. See failed gas safety checks.

The record

The record lists the property, landlord, date of the check, the number of appliances tested, the next check due date and the engineer’s Gas Safe number. See a sample landlord gas safety record.
