When it comes to gas appliances in your home, safety is non-negotiable. In the UK, gas work must be carried out by someone competent and correctly registered for the category of work involved. Understanding Gas Safe registration helps you protect your home, your family, and your paperwork.

What is the Gas Safe Register?

The Gas Safe Register is the official list of gas engineers and businesses registered to work on gas appliances in the United Kingdom, Isle of Man, Jersey, and Guernsey. It replaced the CORGI registration scheme in Great Britain and the Isle of Man on April 1, 2009.

Under the Gas Safety (Installation and Use) Regulations 1998, it is a criminal offence for anyone to carry out gas work unless they are competent and registered with Gas Safe for the relevant scope. This applies to gas work including boiler installation, repair, servicing, and removal.

Nimbus Gas Safe Registration

Nimbus Boilers, Heat Pumps & Renewables displays Gas Safe registration number 966812 for gas work. Before work starts, you can verify the business and the attending engineer's current work categories by:

  • Visiting gassaferegister.co.uk and checking the business registration or engineer details
  • Calling the Gas Safe Register on 0800 408 5500
  • Checking the attending engineer's Gas Safe ID card, including the work categories shown on the back of the card

The Dangers of Illegal Gas Work

Using someone who is not correctly registered for the gas work they are carrying out is a serious safety risk. Poor gas work can lead to:

  • Carbon Monoxide Poisoning: Incorrectly fitted flues or poorly commissioned boilers can leak dangerous, invisible CO gas into your home.
  • Gas Leaks and Explosions: Poorly jointed pipework can create gas leaks, fire risk and explosion risk.
  • Invalidated Warranties and Insurance Problems: Manufacturer warranties and some insurance positions can be affected if gas work is not completed and documented correctly.

How to Verify Your Engineer's Credentials

You should not rely on a logo alone. Check the engineer and the scope of work before gas work starts:

1. Check the Gas Safe ID Card

A registered engineer should have a Gas Safe ID card. Check the front and back of the card:

  • Front of the card: Check the engineer's photo, start and expiry dates, licence number, and security hologram.
  • Back of the card: Check the engineer is qualified for the specific job you need, such as domestic gas boilers, LPG, cookers, fires or other categories where relevant.

2. Verify Online

You can verify an engineer or a business on the official Gas Safe Register website.

Building Regulations Compliance Certificates

When a Gas Safe registered engineer installs a new heat-producing appliance such as a gas boiler, the installation normally needs to be notified to Local Authority Building Control within the required timescale. The Gas Safe Register route can then issue a Building Regulations Compliance Certificate. Keep this document safe because it may be needed when selling the property.

Landlord Legal Obligations

If you are a landlord, you have strict legal duties under the Gas Safety Regulations:

  • You must ensure gas appliances, pipework, and flues provided for tenants are maintained in a safe condition.
  • You must arrange an annual gas safety check by a Gas Safe registered engineer.
  • You must provide a copy of the Gas Safety Record to existing tenants within the required timescale, and to new tenants before they move in.

Frequently Asked Questions

How do I check if an engineer is Gas Safe registered?
Ask to see their Gas Safe ID card and check: the photo matches the engineer, the dates are current, and the back of the card shows they're qualified for the specific work you need. You can also verify online at gassaferegister.co.uk or by calling 0800 408 5500.
What happens if I use an unregistered gas engineer?
It is a criminal offence for anyone not on the Gas Safe Register to do gas work. Unregistered work puts you at risk of CO poisoning, gas leaks, fires, and explosions. Unregistered or undocumented gas work can also affect manufacturer warranty, compliance paperwork and some insurance positions. Check the relevant policy, warranty terms and Gas Safe record.
