No Gas Safety Certificate? Here’s What Happens

If you’re a landlord in the UK, having a valid Gas Safety Certificate (CP12) isn’t just good practice – it’s a legal requirement. Failing to comply can lead to severe penalties, legal action, and even imprisonment. Let’s break down exactly what happens if you don’t have one.

What Is a Gas Safety Certificate?

A Gas Safety Certificate, often called a CP12, is a document issued by a Gas Safe registered engineer confirming that gas appliances, fittings, and flues in your rental property meet safety standards.

Landlords must:

• Arrange a gas safety check annually.
• Provide tenants with a copy of the certificate within 28 days of the check.
• Keep records for at least two years.

What Happens If You Don’t Have One?

1. You’ll Be Breaking the Law

The Gas Safety (Installation and Use) Regulations 1998 make it a criminal offence to let a property without a valid gas safety record.

2. Hefty Fines

Landlords can be fined unlimited amounts by the courts. Even a short delay in renewing your CP12 can lead to penalties.

3. Possible Prison Sentence

If a tenant is harmed due to unsafe gas appliances, you could face up to six months in prison – and in extreme cases, a longer custodial sentence.

4. Invalid Landlord Insurance

Many insurers require an up-to-date CP12. Without one, you risk your policy being void, leaving you financially exposed.

5. Tenant Safety Risks

Gas leaks and carbon monoxide poisoning are life-threatening hazards. Without annual checks, you’re putting lives in danger.

What to Do If Your CP12 Has Expired

• Book a Gas Safe engineer immediately – you can find one via the Gas Safe Register.
• Inform your tenants that you’re arranging the inspection.
• Don’t delay – enforcement action can start the moment your certificate lapses.

How to Avoid Penalties in the Future

• Set annual reminders at least a month before expiry.
• Work with a reliable Gas Safe engineer who keeps records.
• Keep digital and paper copies of your CP12 for proof.

Key Takeaways

• A valid CP12 is a legal requirement for all UK rental properties with gas appliances.
• Penalties for non-compliance include unlimited fines, prison time, and void insurance.
• Annual checks protect both your tenants and your legal standing as a landlord.
