Who needs a commercial gas safety certificate

Under the Gas Safety (Installation and Use) Regulations 1998, anyone who employs staff or controls premises with gas appliances must keep those appliances, flues and pipework in a safe condition. In practice that means a yearly inspection by a Gas Safe registered engineer, with a written record you can show to an insurer, a landlord, a letting agent or an environmental health officer. KB Heating & Plumbing inspects:

  • Offices and business units with gas boilers or warm air heaters.
  • Shops and retail units.
  • Restaurants, cafes, takeaways and pubs (see commercial kitchen gas).
  • Landlords of commercial and mixed-use buildings.
  • Managed buildings, churches, community halls and clubs.

When you need an inspection

  • Every 12 months, as part of routine compliance.
  • Before a new commercial lease starts or when you take over a premises.
  • After new gas work, such as a new boiler, cooker line or appliance.
  • When your insurer, landlord or a building inspector asks for a current record.

What the inspection covers

The engineer checks every gas appliance on the premises and the installation that serves it:

  • A tightness test on the gas installation.
  • Burner pressure and gas rate on each appliance.
  • Flue flow and spillage tests, so fumes are cleared safely.
  • Ventilation for each appliance and any plant room.
  • Safety devices, such as flame failure devices and, in kitchens, the gas interlock.
  • Isolation valves and emergency controls, which must be accessible and labelled.

The record is completed and handed over on the day of the inspection. Inspections can be booked before opening, after closing or at weekends so you do not lose trade.

If something fails

If an appliance is unsafe, the engineer explains the fault, makes it safe and gives you a price to put it right. Many faults can be fixed on the same visit. For heating plant, see commercial heating services.

Commercial gas safety certificate cost in Cardiff

The price depends on the number of appliances and the size of the premises, and it is confirmed before the inspection. Businesses with several sites or landlords with several units can book their inspections together.

Commercial gas safety FAQs

Is a commercial gas certificate a legal requirement?

The law requires gas appliances at work to be kept safe, and an annual inspection with a written record is how most businesses show that. Insurers and commercial landlords usually ask for one.

Is it the same as a landlord CP12?

No. A CP12 is the landlord gas safety record for homes that are let. For rented homes, see landlord gas safety certificates.

Can you service the boiler on the same visit?

Yes. A commercial boiler service can be done at the same visit as the gas safety inspection.
