Landlord Gas Safety Certificate Brentwood

The CP12 — properly called the Landlord Gas Safety Record — is the document proving that the gas appliances, flues and pipework in a let property have been checked and are safe. It is a legal obligation, not an optional extra. Under the Gas Safety (Installation and Use) Regulations 1998, every landlord must arrange a gas safety check at least once every 12 months, carried out by a Gas Safe registered engineer, on each gas appliance and flue they are responsible for.

It applies to almost all rented residential property — houses, flats, HMOs, rooms in shared houses, and holiday lets. If you're a landlord, a managing agent, or you've inherited a let property and aren't sure where the last certificate is, the safest move is to book a check. A valid, in-date record protects your tenants, satisfies your legal duty, and is routinely requested by letting agents, insurers and the courts. Being without one is a false economy that can carry serious consequences.

We make it simple: a fixed price quoted up front, no call-out fee in our coverage area, an engineer you can verify on the Gas Safe Register, and the record issued promptly so you can pass a copy to your tenant inside the legal window.

The legal requirements

What the law actually requires.

The headline rules every landlord with gas in a let property needs to know.

Frequency: A check at least every 12 months on each gas appliance and flue
Who can do it: A Gas Safe registered engineer — nobody else, by law
Who needs one: Landlords of rented residential property — houses, flats, HMOs, rooms, holiday lets
Tenant copy: Within 28 days of the check; to new tenants before they move in
Record retention: Keep the record for at least 2 years
Governing law: Gas Safety (Installation and Use) Regulations 1998 (as amended)

What the engineer checks

Each gas appliance the landlord owns — boiler, fire, hob, cooker
That appliances are burning correctly and at the right operating pressure
Flues and chimneys — that combustion products vent safely outside
Adequate ventilation and air supply for each appliance
A tightness test on the gas pipework to confirm there are no leaks
Safety devices are working — any defect logged and remedial action noted

A useful detail from the 2018 amendment: you can have the check done up to two months before the current record expires without losing the original renewal date — so you can't accidentally shorten your annual cycle by booking early.

Brentwood landlords

CP12 in a commuter-belt lettings market.

Brentwood is a strong lettings market — the Elizabeth Line out of Brentwood and Shenfield stations puts central London within easy reach, which keeps demand high among commuting tenants. That means a lot of let flats, family homes and period conversions changing hands on the rental market, and a lot of landlords who need their gas paperwork in order between tenancies.

We see the full range: buy-to-let flats near the stations, larger HMOs split into rooms, and Victorian and Edwardian conversions around the town with older flues and pipework that warrant a careful eye. Whether you hold a single flat in Shenfield (CM15) or a portfolio across Brentwood, Hutton, Billericay and Ingatestone, we can fit checks around tenancy changeovers and turn the record around quickly so you stay compliant and your tenants get their copy on time.

How it works

Booking your CP12.

01

Book the check

Call with the property address, the gas appliances present, and tenant access details. We give you a fixed price and arrange a slot — ideally inside the two-month early window so your renewal date stays put.

A Gas Safe registered engineer inspects each appliance, flue, ventilation and the pipework, and runs a tightness test. If anything fails we tell you straight away and explain what needs doing.

03

Record issued

You receive the Landlord Gas Safety Record promptly — ready to pass to your tenant within 28 days, or to a new tenant before move-in. Keep your copy for at least two years.

CP12 FAQ

Landlord gas safety questions.

How often do I need a CP12?

At least once every 12 months. Each gas appliance and flue the landlord is responsible for must be checked at intervals of no more than 12 months. You can book the check up to two months before the current record expires without losing your original renewal date, thanks to the 2018 amendment to the regulations.

Is a CP12 a legal requirement?

Yes. Under the Gas Safety (Installation and Use) Regulations 1998, landlords of rented residential property have a legal duty to arrange an annual gas safety check by a Gas Safe registered engineer and to keep a record of it. It applies to houses, flats, HMOs, rooms in shared houses and holiday lets.

What are the penalties for not having one?

Gas safety duties are enforced by the Health and Safety Executive (HSE). Failure to comply can lead to enforcement action, fines and, in serious cases, prosecution. A missing or invalid record can also affect your landlord insurance and your ability to regain possession of the property. The far more important risk is to your tenants' safety — that's the reason the duty exists.

When does my tenant need a copy?

Existing tenants must receive a copy within 28 days of the check being completed. New tenants must be given a copy before they move in. An electronic copy is acceptable if the tenant agrees, but you must provide a paper copy on request. You must keep the record for at least two years.

What happens if an appliance fails the check?

If an appliance is unsafe, the engineer will explain the fault and, with your permission, may turn it off and label it so it isn't used until repaired. The defect and any action taken is recorded. We'll quote the repair so you can get the appliance safe and the property back into a compliant state quickly.

The tenant won't give access — what do I do?

You still have a duty to make every reasonable effort to complete the check. Keep a clear, dated record of your attempts — letters, calls and proposed appointments. We'll work with you and the tenant to find a workable time. Document everything; it shows you took the duty seriously if your compliance is ever questioned.
