When running any business premises that use gas appliances, knowing where you stand with the commercial gas safety certificate law isn’t just a good idea – it’s a legal requirement. Whether you’re running a café, office, warehouse or a large industrial site, gas safety isn’t something you can afford to ignore.

Let’s break it down in simple terms.

What is a Commercial Gas Safety Certificate?

Also known as a CP42 certificate (for catering businesses) or sometimes a gas safety record, this document is issued after a Gas Safe registered engineer inspects your commercial gas appliances, pipework, and ventilation.

The certificate confirms that everything’s safe and up to legal standards. It will highlight any issues or faults, and detail any repairs or follow-up checks that might be needed.

Yes, it absolutely is. Under UK law, all commercial premises that use gas must have annual gas safety checks carried out by a qualified Gas Safe engineer.
This requirement falls under the Gas Safety (Installation and Use) Regulations 1998, which places responsibility on employers, landlords, and business owners to make sure gas appliances are maintained properly and checked every year.

It’s not just about ticking a box – it’s about keeping staff, customers and your premises safe.

Learn the Commercial Gas Safety Certificate Law

Who Needs One?

If your business uses any gas-powered equipment – cookers, heaters, boilers – you’ll need a certificate. This includes:

  • Restaurants, cafés and takeaways
  • Offices with gas heating
  • Schools and care homes
  • Factories and warehouses
  • Rental commercial properties

Landlords of commercial units are also responsible for ensuring the certificate is in place, especially if the tenant has use of gas appliances.

What Happens During the Inspection?

A Gas Safe registered engineer will come out and do a full check. This includes:

  • Looking at all gas appliances to ensure they’re working safely
  • Checking pipework for leaks or damage
  • Making sure there’s proper ventilation and that flues are working correctly
  • Testing safety devices on appliances

If everything’s fine, they’ll issue the certificate. If not, they’ll let you know what needs to be done to put it right.

What If You Don’t Have One?

Not having a valid commercial gas safety certificate is breaking the law. If there’s an accident or gas leak and you haven’t kept up with inspections, you could face fines, legal action, or even imprisonment in serious cases.

It can also cause issues with your insurance – many providers will refuse to pay out if you’ve not followed safety regulations.

How Often Do You Need to Renew It?

The certificate lasts for 12 months, and you’ll need to get a new one each year. It’s worth setting a reminder or working with a reliable engineer who can schedule it annually so you don’t miss the deadline.

How Much Does It Cost?

Prices can vary depending on the size of your premises and the number of appliances. On average, you might pay anywhere from £250 to £650+, but it can be more for larger sites. Think of it as an investment in safety – and peace of mind.

The Bottom Line

The commercial gas safety certificate law exists for a reason – to keep people safe and businesses running smoothly. If you’re unsure about your current certificate, or you’re setting up a new business premises, it’s best to get a qualified engineer in sooner rather than later.

Stay compliant, stay safe, and keep your business on the right side of the law.
