How to Verify a Gas Engineer

Ensuring that gas work is carried out by a properly registered professional is not only a legal obligation—it is a vital safety measure. For landlords, property buyers, and homeowners, verifying gas engineers and businesses through the Gas Safe Register is the most reliable way to confirm compliance.

At Fraser Bond, we ensure that every gas-related service conducted in our managed properties meets the highest safety and legal standards. Here is our step-by-step guide to using the Gas Safe Register to verify gas engineers and businesses across the UK.


What Is the Gas Safe Register?

The Gas Safe Register is the official list of engineers and businesses legally permitted to carry out gas work in the UK. It replaced the former CORGI registration system in 2009 and is now the national standard for gas safety compliance.

Anyone conducting gas installations, servicing, or repairs must be registered. The register confirms that individuals and companies have the required qualifications, certifications, and competencies for safe, legal work on appliances such as boilers, cookers, gas fires, and LPG systems.


How to Verify a Gas Engineer

Before allowing an engineer to begin work, complete the following checks:

1. Obtain the Engineer’s Gas Safe Licence Number

Each registered engineer is issued a unique seven-digit licence number, which appears on their Gas Safe ID card. This number is essential for digital verification.

2. Use the 'Check an Engineer' Tool Online

Visit the official Gas Safe Register website (www.gassaferegister.co.uk) and navigate to the Check an Engineer section. Enter the engineer’s licence number to verify:

  • Their registration status

  • The types of gas appliances they are qualified to work on

  • Whether their licence is currently active

3. Inspect the Gas Safe ID Card on Arrival

When the engineer arrives at your property, request their Gas Safe ID card. Ensure the following:

  • The photograph matches the individual

  • The card has not expired

  • The scope of certified work includes your specific requirements (e.g. boiler, LPG, gas fire)


How to Verify a Gas Business

Verifying the business that employs or contracts the engineer is equally important. Follow these steps:

1. Collect Key Business Information

Obtain the business name and, if available, their Gas Safe registration number.

2. Use the 'Check a Business' Tool Online

On the Gas Safe Register website, go to the Check a Business section and search using the business name or registration number. You will be able to confirm:

  • The business's registration status

  • Whether it is currently active

  • Its list of associated Gas Safe engineers

3. Confirm the Assigned Engineer Is Listed

Review the list of registered engineers under the business name. Confirm that the engineer scheduled to perform the work is included and qualified for the relevant appliance or system type.


Alternative Verification Methods

If online access is unavailable, you can contact the Gas Safe Register helpline on 0800 408 5500. Provide the engineer’s or business’s name and licence number to confirm their registration status with a representative.
