Legal Requirement

What Is A CP12 Record?

A CP12 — Landlord Gas Safety Record is a legal document required under the Gas Safety (Installation and Use) Regulations 1998. Every landlord in England must hold a valid CP12 for every gas appliance in their rental property.

Our Gas Safe registered engineers inspect every gas appliance, check flues and ventilation, verify safety devices, and measure gas pressure — issuing your official certificate the same day.

Failure to hold a valid CP12 can result in fines up to £6,000 and criminal prosecution. Don't take the risk.
