Bristol Gas Safety
A gas safety certificate (CP12) is a legal requirement for every rental property with gas appliances. It must be renewed every 12 months. Gas Safe registered engineers covering all Bristol postcodes from £60.
Book Your Gas Safety Check — from £60 →A gas safety certificate — officially called a Landlord Gas Safety Record, or CP12 — confirms that all gas appliances, fittings and flues in a rental property have been checked and are safe. If your property has a gas supply, this check is a legal requirement that must be renewed every 12 months, without exception. Our Gas Safe registered engineers carry out gas safety checks across all Bristol postcodes BS1–BS16, and we issue the certificate the same day as the inspection.
A gas safety certificate is the written record produced after a Gas Safe registered engineer has inspected all the gas appliances, pipework and flues in a property and confirmed they are safe to use. For landlords, it is formally known as the Landlord Gas Safety Record — commonly called a CP12 after the form number historically used for the check.
Only Gas Safe registered engineers are legally permitted to work on gas appliances in the UK. When you book with us, every engineer is Gas Safe registered — you can verify their registration number at gassaferegister.co.uk.
It depends on your situation and whether the property has a gas supply.
Under the Gas Safety (Installation and Use) Regulations 1998, every landlord who lets a property with a gas supply is legally required to have all gas appliances, fittings and flues checked annually by a Gas Safe registered engineer. There are no exceptions for older properties, properties with newer appliances, or properties where tenants look after their own maintenance.
An annual gas safety check is not a legal requirement for owner-occupied homes, but it is strongly recommended. Gas appliances can degrade over time and develop faults that are not obvious — including producing carbon monoxide, which is odourless and can be fatal.
If your property has no gas meter, no gas appliances and no live gas supply, you don't need a gas safety certificate. However, confirm this is definitely the case: some properties have a capped gas supply on a live meter — in which case the supply still technically exists and a check may be required. If in doubt, check with your gas network provider or ask us.

The engineer needs access to every gas appliance in the property — boiler, gas fires, hobs, ovens, and any other gas-powered equipment. They'll also need to locate the gas meter and any isolating valves. For tenanted properties, arrange access in advance so the engineer can complete the check in one visit.
The engineer checks the entire gas supply system for leaks. If a leak is detected, the supply will be isolated and the leak must be repaired before the check can continue.
Each appliance is tested individually: the engineer checks the flame picture, ventilation, flue draw, safety device operation, and combustion readings on boilers. Any appliance with a problem is classified — see the section below on what happens if an appliance fails.
The engineer completes the Landlord Gas Safety Record (CP12) listing every appliance checked, its condition, and any action required. We aim to issue the certificate on the day of the check so you can give a copy to your tenants promptly.
If the engineer identifies a problem with an appliance, they will classify it using one of three designations. Here is what each one means.
The appliance poses an immediate risk to life. The engineer is legally required to disconnect it on the spot. It cannot be used until it has been repaired or replaced and reinspected.
The appliance has a fault that could become dangerous. It should be repaired as soon as possible. The engineer will advise on urgency and the tenant should be made aware.
The appliance doesn't meet current installation standards but isn't immediately unsafe. The certificate can still be issued — improvement is recommended but not urgently required.
If an appliance is classified as Immediately Dangerous, the engineer is legally required to disconnect it — this is non-negotiable and is done to protect your tenants. Most ID classifications can be resolved by repairing or replacing the appliance. We can advise on the quickest route forward once you have your report.
From £60
Covering all Bristol postcodes BS1–BS16. Price confirmed before booking — no surprises on the day.
The main factor affecting price is the number of gas appliances. The check on a single boiler takes far less time than inspecting a boiler, a gas fire, a gas hob and a gas oven — all of which need individual testing and recording on the certificate.
Need your gas safety, EPC and EICR done at the same time? Most Bristol landlords need all three. Ask about our landlord compliance package when you request a quote — combining services for the same property simplifies scheduling and is often more convenient. See our full pricing guide for an overview of all our services.
Tell us your property address and number of gas appliances, and we'll confirm your price and a convenient appointment date.

Unlike an EICR (5 years) or EPC (10 years), there is no long window in which to forget. If your certificate expires while tenants are in the property, you are immediately in breach of the law.
There is no grace period. The day after your certificate expires, if a tenant is in the property, you are in breach. Don't rely on tenants to remind you — keep the renewal date in your calendar and book ahead.
If you book your renewal within the 2 months before the current certificate's expiry date, the new certificate will run from the old expiry date — not from the date of the new check. You don't lose any time on your certificate by renewing slightly early, and you won't have to worry about a last-minute scramble.
Providing tenants with a current gas safety certificate is a precondition for serving a valid Section 21 notice. If you haven't given your tenants a copy of the most recent certificate, any notice you serve will be invalid. Keep your paperwork in order.
Gas safety is just one of several annual and periodic obligations for Bristol landlords. You also need a valid EPC — check whether your situation requires one. See our Bristol landlord compliance checklist for a complete overview of what you need and when each certificate needs renewing.
From £60. The exact price depends on the number of gas appliances in the property. We provide a confirmed quote before booking. For a full comparison of our service prices, see the Bristol pricing guide.
Typically 30 to 60 minutes, depending on the number of appliances. A property with a single boiler will usually take around 30 minutes. A property with a boiler, gas fire, gas hob and gas oven will take longer. We'll give you a realistic estimate when you request a quote.
Every 12 months for rental properties — no exceptions. Annual checks are also recommended for owner-occupied homes. Don't let it lapse: there is no grace period, and an expired certificate puts you immediately in breach as a landlord. If you also need an EICR or EPC, ask about combining services.
Yes — if you have the check done within the 2 months before your current certificate's expiry date, the new certificate runs from the old expiry date, not from the date of the new check. So renewing early doesn't cost you any coverage time.
A gas safety check is a legal safety inspection confirming all gas appliances, fittings and flues are safe. It produces a CP12 certificate. A boiler service is a maintenance procedure — cleaning, adjusting and optimising the boiler — that doesn't produce a legal certificate. Some engineers offer both in a single visit, but they are different things. The CP12 is what landlords are legally required to provide to tenants.
The penalties are serious: an unlimited fine and/or up to 6 months' imprisonment. You also cannot serve a valid Section 21 (no-fault eviction) notice without having provided tenants with a current certificate. In the most serious cases — where a tenant is harmed by a faulty appliance — landlords have faced manslaughter charges. A £60 annual check is a straightforward way to stay compliant and keep your tenants safe.
