What Happens During Your Gas Safety Check
A Gas Safe registered engineer works through every appliance methodically, exactly as required under the Gas Safety (Installation and Use) Regulations 1998.
Appliance inspection
Every gas appliance supplied by the landlord (boiler, hob, fire, cooker) is visually checked for correct installation, ventilation, and any signs of wear or damage.
Tightness testing
The whole gas installation is pressure-tested to confirm there are no leaks anywhere in the pipework before any appliance is tested individually.
Combustion & flue check
The engineer checks flue flow and spillage on each appliance, confirming combustion products are venting safely outside rather than into the property.
Safety device checks
Flame failure devices and other safety cut-offs are tested to confirm they’d actually shut an appliance down if something went wrong.
Certificate issued same day
Your CP12 Gas Safety Record is completed and emailed the same day, ready to give tenants, required within 28 days for existing tenants, before move-in for new ones.
Gas Safety FAQs
Is a Gas Safety Certificate a legal requirement?
Yes. Under the Gas Safety (Installation and Use) Regulations 1998, all landlords must have a Gas Safety check carried out annually by a Gas Safe registered engineer. A copy must be given to existing tenants within 28 days and to new tenants before they move in.
What does a Gas Safety check cover?
The engineer inspects all gas appliances supplied by the landlord, boilers, gas fires, hobs, and pipework. They check for safe operation, adequate ventilation, and any risk of carbon monoxide leaks.
How long does a Gas Safety check take?
Most checks take between 30–60 minutes depending on the number of gas appliances in the property.
How long is a Gas Safety Certificate valid?
A Gas Safety Certificate (CP12) is valid for 12 months. Landlords must arrange a new check every year.
What happens if my property fails?
If an appliance is found to be unsafe, the engineer will advise on immediate action required. Unsafe appliances must be repaired or replaced before tenants can use them.
Can I combine a Gas Safety check with other services?
