A landlord gas safety check by Hollis Plumbing and Gas is £75 and covers the boiler, gas hob and gas fire in one visit, with the CP12 certificate emailed the same day. Landlords in the UK are legally required to arrange this check every 12 months on every rental property with a gas appliance.
Every landlord letting a property with a gas appliance in the UK has a legal obligation to arrange an annual gas safety check. The certificate that comes out of that check is called a CP12. This guide covers what actually gets checked, how the fixed £75 all-in price with Hollis Plumbing and Gas works, and what happens when something fails.
What the CP12 is
The CP12 is a Landlord Gas Safety Record. It is issued by a Gas Safe registered engineer after they have inspected every gas appliance and gas flue in the property. Once the check passes, the certificate is valid for 12 months and must be renewed before it expires.
As a landlord you must:
- Arrange the check every 12 months on every gas appliance you own in the property.
- Give a copy of the certificate to your tenant within 28 days of the check (or before they move in, if it is a new tenancy).
- Keep the record for at least two years.
Failing to keep a valid CP12 in place is a criminal offence. The Health and Safety Executive can prosecute, and if something goes wrong you are personally liable.
What actually gets checked
The inspection covers every gas appliance and every gas flue in the property. On a typical Cardiff rental that usually means the boiler, a gas hob and (sometimes) a gas fire. For each one, we check:
- The appliance is on the manufacturer's operating pressure and burning cleanly.
- The flue or chimney is drawing correctly and safely.
- Ventilation to the appliance is adequate.
- All safety devices (flame supervision, thermostats, seals) work as designed.
- There are no gas leaks on any joint between the meter and the appliance.
The inspection is a check, not a service. If you also want the boiler serviced (a full clean and tune) that is a separate £90 job. Most landlords book both at the same time so it is one visit.

Call to BookHow the £75 all-in price works
The £75 is a fixed price for the boiler, the gas hob and the gas fire in the same property, all inspected together in one visit. That is what a typical rental has, and it is the price most landlords pay.
If the property has a different combination (say, two boilers, or an additional gas appliance in an outbuilding), tell us when you book and we will confirm the price before we arrive. There are no surprise extras added on the day.
If an appliance fails the check
If we find a fault that makes an appliance unsafe, we will:
- Explain in plain English what is wrong and why it is a safety issue.
- Isolate the appliance if needed, so it cannot be used until it is repaired.
- Quote separately for the repair, so you can either give us the go-ahead or arrange it elsewhere.
The certificate is only issued once every appliance in the property is safe. That is a legal requirement, not a discretionary call.
Working with lettings agents
We work with several lettings agents across Cardiff and the Vale of Glamorgan. If your agent handles the booking, we can liaise directly with them and with the tenant to arrange access, and we email the CP12 straight to the agent as soon as the inspection is signed off. That keeps the paperwork clean and takes the coordination off your plate.
Frequently asked questions
About 45 to 60 minutes for a standard boiler, hob and fire. Longer if there are more appliances or the property has awkward pipework.
No. The CP12 only applies to gas appliances. All-electric properties do not need one, though you still have obligations under the electrical safety regulations.
Yes. You can arrange the next check up to two months before the current certificate expires and the new expiry date still runs from the old one. That is useful for keeping the annual rhythm predictable.
You still have the legal obligation to make reasonable attempts to arrange access. Keep a written record of every attempt and give the tenant reasonable notice. If access is repeatedly refused, seek advice from a landlord association or your lettings agent.
