In order to issue a gas safety certificate (CP12) the engineer has to undertake the following gas safety checks:

  • Gas supply
  • Gas appliances
  • Gas flues
  • Ventilation

What do gas safety checks include for a gas fire?

  • Check appliance for gas tightness
  • Check the appliance is working at the correct gas pressure
  • Check that the ventilation provided is adequate
  • Gas Safety Landlords engineers also check the satisfactory operation of all the flame failure devices
  • Check to ensure the piping is rigid and not flexible hose
  • Check for signs of unsafe or irresponsible operation
  • Check flame pitcher is good- should be clear blue flame
  • The gas rate and pressure of burner against recommended values also undergo gas safety checks.
  • Smoke pellet test to ensure flue is clear
  • Check catchment place behind fire is clean
  • Verify that the appliance is safe to use


An appliance can only pass all gas safety checks for landlords and have a gas safety certificate (CP12) issued when the above have all been satisfactorily completed.

A gas safety landlords certificate (CP12) can be carried out for you by a Gas Safety Landlords engineer within 24- 48 hours.
