Landlord Gas Safety Certificates: What the Law Actually Requires

CP12, annual checks, access disputes and record keeping - a plain-English guide to your obligations as a landlord, and the mistakes that most often catch people out.

If you let a property with gas appliances in England, the Gas Safety (Installation and Use) Regulations 1998 place three duties on you. They are not complicated, but the detail of how they are enforced catches a lot of landlords out.

The three core duties

• Have every gas appliance and flue you own checked for safety every 12 months by a Gas Safe registered engineer
• Provide the tenant with a copy of the record within 28 days of the check, or before a new tenant moves in
• Keep a copy of each record for at least two years

The certificate is commonly called a CP12, which is simply the old form number and has stuck. Officially it is a Landlord Gas Safety Record. Either name refers to the same document.

The twelve month rule is not quite what people think

You can have the check carried out up to two months before the current certificate expires without losing the original renewal date. This matters more than it sounds - it means you can book early to avoid a lapse without effectively shortening your cycle each year, which is what happens if you renew late and reset the clock.

When a tenant will not grant access

This is the most common practical problem and the one that generates the most anxiety. The regulations expect you to take reasonable steps, and to be able to evidence them. That means writing to the tenant, explaining the legal obligation and the safety rationale, offering appointment options, and keeping a record of every attempt.

Repeated documented attempts are your defence. Forcing entry is not - that risks breaching the tenancy. If access is genuinely being refused over a sustained period, take legal advice before acting rather than after.

What happens if you do not comply

Enforcement sits with the HSE, and penalties range from improvement notices through to unlimited fines and, in the most serious cases involving harm, custodial sentences. Just as significantly, most landlord insurance policies are void where a valid gas safety record is not in place - which tends to surface at precisely the worst moment.
