Verifying that a gas engineer is Gas Safe registered is a legal and safety-critical responsibility for landlords, tenants, property buyers, and investors across the UK. Only engineers listed on the Gas Safe Register are legally permitted to carry out gas work in residential properties—and only their inspections can issue a valid CP12 Gas Safety Certificate.
This guide from Fraser Bond, a leading property advisory and compliance expert, explains how to confirm an engineer’s registration, what information is accessible through the Gas Safe Register, and why verification is essential for compliance and peace of mind—especially in the highly regulated London rental market.
Under the Gas Safety (Installation and Use) Regulations 1998, all gas work in rented or tenanted properties must be carried out by engineers who are officially registered with the Gas Safe Register.
Failure to verify an engineer’s status can result in:
Invalid CP12 Gas Safety Certificates
Insurance claim disputes and policy breaches
Fines or prosecution from local authorities
Unsafe or non-compliant gas installations
Whether you are preparing a property for new tenants, purchasing a tenanted investment property, or reviewing historical compliance documentation, engineer verification is a non-negotiable step.
Fraser Bond recommends using the Gas Safe Register’s public search tool to confirm an engineer’s registration quickly and accurately.
Access the UK’s government-recognised gas engineer database at www.gassaferegister.co.uk. This is the sole legal authority for checking gas credentials nationwide.
Select the “Check an Engineer” function from the homepage or navigation menu. You may search using:
The engineer’s Gas Safe ID number (found on their ID card or CP12 certificate)
The engineer’s full name
The registered business name or company number
Once submitted, your search will confirm:
Whether the engineer is currently registered
The expiry date of their Gas Safe registration
The types of gas work they are certified to perform (e.g. boilers, fires, cookers)
Their associated business details
Whether they were active at the time of the inspection
This verification process ensures the engineer responsible for your CP12 certificate was legally qualified and appropriately certified at the time of service.
While the Gas Safe Register is the official verification tool, it does not provide access to actual Gas Safety Certificates or inspection records. Specifically, the register:
Does not store or issue past CP12 certificates
Cannot verify a CP12 by property address or postcode
Cannot confirm whether an inspection occurred at a specific property
Gas certificates are considered private compliance documents. They are typically retained by the issuing engineer, the managing agent, or the property owner. Buyers, tenants, or solicitors requiring proof must request it directly from the responsible party.
