What is a landlord gas certificate?

“Landlord gas certificate” or “gas safety certificate” is an official document that proves that a landlord has met his/her obligations to ensure that all of the gas appliances in the property are safe to use. It is required by the law and should be renewed annually.

You might hear people referring to it as “CP12”, “gas safety record”, or “landlord gas safety record”. Don’t get confused, those are names of the same document!

Do you need a landlord gas certificate for a new boiler?

You don’t need to get another inspection before the due date if your new boiler has been installed by a Gas Safe registered engineer. A professionally installed appliance is considered safe for 12 months from the date of installation. However, your next inspection still should be performed one year after the previous one if you have other gas appliances, such as a gas oven or hobs.

Let’s say you have inspected your old boiler in January 2021 together with the rest of the gas appliances. Due to some circumstances, you get a new boiler in June. Here comes the question of whether you need to perform another inspection before the previous Gas Safety Check expires. In this situation, if other gas appliances have been checked in January 2021, then the due date for your next gas safety inspection is January 2022.

Why as a landlord you need to have one

Even though everyone is aware of how dangerous a neglected gas appliance can be, a kind reminder won’t hurt anyone. Unsafe appliances can endanger your tenants’ lives. Such unpleasant incidents as gas leaks can result in fires and even explosions. And that’s not all! Around 60 people die from carbon monoxide poisoning in the UK every year, due to a gas leak from a faulty and unmaintained gas appliance. Therefore, according to the Gas Safety (Installation and Use) Regulations 1998, an owner of a property that has gas fittings, appliances and flues has to carry out an annual check.

The landlord’s responsibility includes the following three obligations:

Maintenance of the gas appliances 

All the gas appliances have to be checked regularly following the manufacturer’s instructions. If those are not available, the minimum work should include external and internal appliance examination, pipework check, performance test, and restoration, if needed.

Gas Safety Checks

To assure the tenants that the gas appliances are suitable for continued use, landlords should order a Gas Safety Check every 10-12 months after a previous check. The same is relevant for newly installed appliances. If your appliance was installed less than a year ago, you need to have it checked within 12 months of the installation date. The inspection needs to be performed only by a Gas Safe registered engineer.


Landlords should provide their tenants with a copy of the latest safety check record within 28 days of its completion. If new tenants move into your property, you should provide them with a copy of the latest Gas Safety Check. The record must include:

  • the address of the property; 
  • the date when the check was performed; 
  • the names and locations of each gas appliance in the property;
  • information about the engineer who performed the check;
  • any identified defects

If an engineer has noticed a defect, he should provide you with the recommendations for any further work that is required. The gas safety record, together with any documents related to appliances repairs, should be kept for two years from the issue date. You can also consider the idea of investing in a landlord boiler cover plan that includes a gas safety certificate.

What Certificates Do You Need To Rent Out Your Property

Do you need to register your new boiler?

When you install a new heating appliance, you should inform your local authorities within 30 days from the installation date. It concerns not only the boiler itself but any heating appliance. 

Usually, a Gas Safe engineer reports through the Gas Safe register and within 15 days, you should receive a Building Regulations Compliance Certificate by post. 

For Scotland and Northern Ireland, the requirements may vary. You can find all the relevant information on the official Scottish government and the Building Control Northern Ireland websites.

It is in your best interest to check if your engineer has notified the authorities. Furthermore, if you need to order a replacement certificate, you should contact your Gas Safe register. The duplicate certificate costs £6.

A Building Regulations Compliance Certificate is not the same as the Gas Safety Check! A Gas Safety check serves as proof that all of your gas appliances are safe to use, whereas the Building Regulations Compliance Certificate shows that a boiler and heating appliances are installed in accordance with all regulations.
