Need a Commercial Gas Test Certificate? We’re Just a Call Away

If you run a business that relies on gas appliances or systems—whether that’s a café with a commercial kitchen, a hotel, or an industrial site—you’ll likely need a commercial gas test certificate. But what exactly is it, and why is it important?

Let’s break it down in simple terms.

What is a Commercial Gas Test Certificate?

A commercial gas test certificate is a document issued by a qualified Gas Safe registered engineer. It confirms that your gas appliances, pipework, and systems have been inspected and tested to make sure they’re working safely and meet current UK regulations.

This isn’t just about ticking a box for compliance. It’s about protecting your staff, customers, and property from potentially dangerous gas leaks, carbon monoxide poisoning, or fire risks.

When Do You Need One?

You’ll need a valid commercial gas safety certificate if:

  • You run a business with gas appliances (e.g. cookers, boilers, heaters).
  • You’re a landlord of a commercial property.
  • You’re leasing a premises to a business that uses gas equipment.
  • You’ve installed or altered gas pipework or appliances.
  • You need to prove gas safety for insurance or regulatory purposes.

Even if the law doesn’t strictly require it in your situation, regular gas safety checks are simply good practice—and many insurers will insist on it.

How Often Should It Be Done?

Most commercial premises need annual gas safety inspections. Your engineer will carry out various checks—pressure tests, flue inspections, appliance condition—and if everything’s in good order, they’ll issue the commercial gas test certificate on the spot.

If anything needs fixing or updating, they’ll let you know and may be able to sort it during the visit.

Who Can Issue a Commercial Gas Safety Certificate?

Only engineers registered with the Gas Safe Register are legally allowed to carry out these inspections and issue certificates. Always check their ID and credentials. Commercial gas systems are more complex than domestic ones, so you’ll want someone who’s qualified specifically for commercial work.

What Does the Certificate Include?

A proper commercial gas test certificate will show:

  • The name and Gas Safe registration number of the engineer
  • Details of the business and site
  • A list of appliances and pipework tested
  • The results of safety checks
  • Any defects or recommendations
  • Confirmation the installation is safe (or not)

You should keep a copy for your records and give one to your landlord or insurer if needed.

Why It Matters

Aside from the legal and insurance requirements, having your gas systems properly tested and documented gives peace of mind. It shows your business takes safety seriously—and that can be reassuring to both staff and customers.
Faulty gas equipment can be deadly. A routine inspection and certificate could make all the difference.

FAQs

A Gas Safe engineer will check all gas appliances, pipework, flues, and ventilation. They’ll test for leaks, confirm everything’s working properly, and flag any issues. If all’s well, they’ll issue your certificate.

No – only a Gas Safe registered engineer who is qualified for commercial work can carry out the inspection and issue a certificate. Always double-check their credentials before booking.

If any appliance is found to be unsafe, the engineer may label it as ‘Immediately Dangerous’ or ‘At Risk’. They’ll disconnect it or recommend urgent repairs before issuing a certificate. Safety always comes first.

Yes. Even if you rarely use your gas appliances, they still need to be maintained and tested regularly. Gas leaks and faults can develop over time, even with low usage.

They’re similar but not exactly the same. A landlord gas safety certificate (also known as a CP12) usually applies to residential properties. A commercial gas certificate applies to business or non-domestic premises and often involves more detailed checks.
