Commercial kitchen gas safety certification

If you have a commercial kitchen, then you have a legal duty to ensure any gas appliances on your premises are checked and certified by a Gas Safe qualified engineer at least once a year. Commercial kitchens are subject to rigorous regulation because of the ventilation required and the risk of fire if correct guidance isn’t followed. Also, equipment can become potentially hazardous if not maintained, so needs to be regularly inspected for leaks and faults.

According to the UK gas safety regulations and British Standard BS6173, any food business operating a commercial kitchen must install a gas safety interlock system. This is designed to shut off the gas supply in the event of a fan failure, and also ensures the airflow rates achieved by commercial kitchen extraction systems meet the minimum standards as set out by the Building Engineering Services Association (BESA). Gas interlock systems operate by monitoring the operation of the fan or fans within the extraction system by one of two possible methods. Either a differential air pressure switch can be used that senses the static air pressure and shuts off at a defined level of air throughout, or an electrical current sensor monitors the electrical current to the fan to achieve the same objective.

The safety certificate that is issued annually by a registered Gas Safe engineer to cover all gas installation and appliances in your kitchen is a CP42. Certificates are valid for 12 months from date of issue and are required every year by law. They specifically cover commercial kitchen facilities, such as:

  • Restaurants, cafes and clubs
  • Take-away shops and fast food outlets
  • Catering businesses, mobile or fixed kitchens
  • Staff, schools, MOD, NHS, Government canteens
  • Care homes, nursing homes and daycare centres
  • Any food production centres
  • All kitchens in both private and public sectors

Before issuing a CP42 gas safety certificate, the engineer will inspect your equipment and any machinery that has a gas supply to it, and complete a thorough examination of your pipework, gas interlock system, plus the extraction in your kitchen. Your insurance cover will almost certainly depend on you having a current CP42 Gas Safety Certificate. And if you lease your property, don’t assume this is the responsibility of the landlord. Usually, leases include clauses that pass responsibility for gas safety to the leaseholder.

How much is a CP42 commercial catering kitchen gas safety certificate? CP42 catering gas safety certificates cost between £200-300 depending on the size of the kitchen and how much gas equipment is installed. The cost will increase for larger kitchens with multiple extraction canopies.

There are other commercial gas safety certificates to consider as well. In certain circumstances, you may need a Gas Testing and Purging inspection (CP16), or to obtain a Gas Installation Safety Report (CP17), or Gas Commissioning/Servicing Record (CP15).
