Engineer Details
☐ Engineer’s full name, Gas Safe registration number, and signature are present.
☐ Company name, address, and contact details are correct.
☐ Engineer’s registration is valid and covers the correct type of work (domestic/LPG etc.).
Date of Inspection
☐ Certificate date is within the last 12 months.
☐ Next due date diarised to avoid expiry.
Landlord / Property Details
☐ Landlord’s name and address are correct.
☐ Rental property address (including flat/apartment number) is accurate.
Appliances Tested
☐ All gas appliances in the property are listed (boiler, hob, fire, water heater, etc.).
☐ Confirmation that each appliance has been tested and is safe.
Results of Safety Checks
☐ Test results recorded for each appliance (pressure, flue, ventilation, etc.).
☐ No appliances marked as ‘At Risk’ or ‘Immediately Dangerous’.
Defects and Remedial Action
☐ Any defects identified are clearly noted.
☐ Recommended or required remedial action is recorded.
☐ Confirmation that remedial works have been completed if applicable.
Pipework & Installation Checks
☐ Gas tightness test carried out.
☐ Visible pipework inspected and condition noted.
Expiry / Validity

Common Pitfalls to Avoid
• Missing appliances (e.g. unused gas fires).
• Incorrect address (landlord’s home vs rental property).
• Expired certificates (ensure continuous cover).
• Engineer registered but not qualified for specific appliances (e.g. fires).
