Gas Safe Register in Wales

If you live in Wales and use gas in your home or rental property, it’s essential to understand your responsibilities under the Gas Safety (Installation and Use) Regulations 1998. This includes ensuring that all gas appliances are checked annually by a Gas Safe registered engineer.

In this guide, we’ll explain what the Gas Safe Register means for residents and landlords in Wales, how to find local engineers, and why regional compliance matters.

The Gas Safe Register is the UK’s official gas registration body. It replaced CORGI in 2009 and is responsible for regulating engineers who work on gas appliances such as boilers, cookers, and fires.

In Wales, as in the rest of the UK, it is a legal requirement for anyone working on gas appliances to be on the Gas Safe Register.

Wales follows the same national regulations as England and Scotland. However, housing and tenant enforcement may fall under Welsh local authorities, particularly in relation to:

• Social housing compliance.
• Tenant rights and landlord obligations.
• Licensing under Rent Smart Wales.

Landlords in Wales must:

• Ensure all gas appliances and flues are checked once every 12 months.
• Provide a valid Gas Safety Certificate (CP12) to tenants.
• Use a Gas Safe registered engineer for all gas work.
• Comply with Rent Smart Wales licensing (if renting out residential property).

You can easily check if an engineer or business is on the register:

1. Visit the Gas Safe Register website.
2. Click on “Find an Engineer”.
3. Enter your postcode, town, or “Wales” to filter results.
4. Confirm their credentials by asking for their Gas Safe ID card.

When checking, make sure:

• The engineer is qualified for the specific appliance (e.g. boilers, cookers, LPG, etc.).
• They have a valid license number and visible contact details.
• Their qualifications are up-to-date on the register.

• Gas Safe Register Customer Support: 0800 408 5500.
• Rent Smart Wales: rentsmart.gov.wales.
• Local Authority Housing Teams: Responsible for landlord enforcement and tenant safety.
  

While the Gas Safe Register is a UK-wide system, working with local Welsh engineers offers benefits:

• Better availability for urgent jobs.
• Familiarity with local council requirements.
• Easier coordination with Rent Smart Wales obligations.
  

• Gas Safe registration is legally required for gas engineers in Wales.
• Landlords must arrange annual safety checks and issue certificates to tenants.
• Use the Gas Safe Register to find and verify qualified engineers.
• Local knowledge and compliance with Welsh housing rules matter.

Staying compliant in Wales means keeping up with UK-wide gas regulations while also understanding local landlord requirements. Whether you’re a homeowner in Cardiff or a landlord in Swansea, checking the register and using qualified professionals ensures safety and peace of mind.

While you’re making sure your property is gas safe, it’s also worth checking your Energy Performance Certificate (EPC) rating. Not sure what your EPC rating is?
