Why Do You Need a Gas Certificate?

Safety isn’t the only reason you need a valid gas certificate. Failing to have a current CP12 certificate can result in:

Legal penalties and fines

Voided landlord insurance

Risk to tenant safety and wellbeing

Difficulty renting or selling your property

Our qualified engineers handle everything from the inspection to issuing your official gas certificate, so you stay compliant and worry-free.

What is a CP12 Certificate?

A CP12 certificate, also known as a landlord gas certificate, is a legal requirement for all rental properties in the UK. It proves that all gas appliances, pipework, and flues in your property have been inspected and declared safe by a qualified Gas Safe engineer.

Our team issues CP12 certificates after a thorough inspection of your property. We test boilers, cookers, and other gas appliances to ensure they’re operating safely and efficiently.

If you’re a landlord searching for “gas safe register check” or “gas certificate Cardiff,” KB Heating & Plumbing is the trusted name to call.
