How to Verify If Your Gas Engineer Is Certified to Work on Boilers and Gas Systems

Before hiring anyone to install, repair, or service gas appliances, it is essential to confirm they are a Gas Safe registered engineer. This is not only a legal requirement in the UK—it is a critical safety measure that protects lives, properties, and your liability as a landlord or homeowner.

At Fraser Bond, we provide expert guidance to help landlords, buyers, and property managers verify engineer credentials, ensure compliance, and manage all aspects of Gas Safety Certificate (CP12) obligations.

Why Engineer Certification Matters for Gas Safety Compliance

Only engineers listed on the Gas Safe Register are legally permitted to work on gas appliances in the UK. Failure to verify a contractor’s registration can result in:

• Unsafe installations or system failures

• Gas leaks or carbon monoxide risks

• Voided building or landlord insurance

• Legal fines and prosecution under the Gas Safety (Installation and Use) Regulations 1998

Fraser Bond works exclusively with certified engineers across London to deliver fully compliant services for residential landlords, developers, and homeowners.

Three Ways to Check If Your Gas Engineer Is Certified

Before allowing any gas-related work to begin, follow these steps recommended by Fraser Bond:

1. Ask to See the Gas Safe ID Card

All registered engineers carry a Gas Safe ID card. Check:

• The engineer’s photograph

• The card’s expiry date

• The types of gas appliances and systems they are licensed to work on (e.g. boilers, cookers, fires)

• Their unique 7-digit licence number

2. Use the Gas Safe Register Online

Visit the official Gas Safe Register website and use the following tools:

• Check an Engineer: Enter their name or licence number

• Check a Business: Search the company they work for

These tools confirm whether the individual or business is currently certified and what categories of work they are authorised to perform.

3. Contact the Helpline for Verification

If you are unable to verify credentials online, call the Gas Safe Register helpline at 0800 408 5500 for confirmation. Keep the engineer’s full name and licence number ready for faster results.
