UK commercial-kitchen gas decision guide
A commercial kitchen needs evidence that its gas system is safely maintained—not a certificate name without a defined scope
If the kitchen uses natural gas or LPG, identify the dutyholder, every appliance, the supply and pipework, ventilation, extraction and interlocks. Upkeepone can then check the suitable fixed-kitchen, mobile-catering, service, repair or commissioning route before quoting.
The short answer
Gas-using kitchens need safe maintenance and suitable evidence; CP42 is a common record name
Keep gas equipment in a safe condition
HSE says employers in hospitality and catering must ensure applicable gas appliances, flues, pipework and safety devices are safely maintained and competently inspected.
Record the kitchen that was actually checked
A CP42-style record can help demonstrate maintenance, but it should name the fuel, supply, appliances, scope, tests, findings, limitations and responsible engineer.
Annual is guidance, not a blanket expiry rule
HSE says intervals vary with equipment and use and should follow manufacturer recommendations, with annual inspection a reasonable general minimum.
Match the exact Gas Safe categories
Restaurants and similar premises need a Gas Safe registered engineer qualified for the fuel, commercial catering equipment and work involved.
Choose the closest route
The right visit depends on the kitchen, fuel, recent changes and requested evidence
| Your situation | Likely route to discuss | Evidence to send first | Do not assume |
|---|---|---|---|
| Fixed restaurant, pub, hotel, school or takeaway using gas | Commercial catering inspection and CP42-style gas-safety record, with service added if required. | Postcode, fuel, appliance list, pipework, ventilation, interlock and previous records. | That every appliance is covered simply because one certificate exists. |
| Food truck, trailer, horsebox, stall or mobile bar using LPG | Mobile catering LPG or CP44 route with the complete unit and supply arrangement. | Unit, cylinders, regulators, hoses, pipework, every appliance, movement and organiser wording. | That a fixed-kitchen CP42 record covers the vehicle or event. |
| New, replaced, moved or converted appliance | Installation or commissioning checks, followed by the appropriate wider inspection record. | Appliance data, fuel, input, layout, extraction, make-up air, pipework and commissioning history. | That an older kitchen record remains suitable after the change. |
| Known fault, unsafe notice, failed flame or smell of gas | Emergency action where appropriate, then diagnosis, repair and separately scoped return checks. | Do not delay the emergency route; provide the notice, appliance and fault information when safe. | That a routine certificate appointment is an emergency-response service. |
| Landlord, council, insurer, franchise, venue or contract asks for evidence | Forward the exact request so the inspection and record can be matched to it. | Requester wording, deadline, dutyholder, kitchen scope, fuel and complete equipment list. | That the words "gas certificate" identify one universal document. |
What CP42 should mean in practice
A record is useful only when the scope can be understood later
CP42 is widely used as shorthand for a commercial catering gas-safety record, particularly for fixed kitchens. It should not be sold as a universal licence to trade or as proof that every legal, fire, electrical, food-hygiene, landlord or building duty has been met.
The premises, natural-gas or LPG supply, every included appliance, accessible pipework, ventilation, extraction, interlocks, checks, findings, defects and limitations should be identifiable. Omitted or inaccessible equipment should not be silently treated as covered.
Potential inspection scope
Show the complete gas path, kitchen airflow and appliance load
Natural gas, cylinders or bulk LPG
Identify the meter or LPG storage, regulators, supply pressure, isolation, emergency controls and any landlord or supplier boundary.
Accessible routes, joints and appliance inlets
Show visible pipework, valves, supports, flexible connectors, quick-release devices, restraints and damage or alterations.
Cookers, ovens, grills, fryers and water heaters
Provide make, model, fuel, input and data-plate photographs for installed, movable, spare or externally used equipment.
Safe operation and products of combustion
Applicable combustion, flame supervision, flues, clearances and signs of heat damage or incomplete combustion are considered.
Canopy, fans and make-up air
HSE highlights adequate make-up air and ventilation because poor airflow can contribute to carbon-monoxide accumulation.
Match the arrangement to the appliances
The gas and ventilation relationship, proving arrangement, shut-off controls and relevant appliance or flue requirements need competent assessment.
Inspection and maintenance frequency
Use the earliest applicable maintenance requirement
HSE says catering gas inspection periods may vary depending on the equipment and its use, and should follow manufacturer recommendations. Annual inspection is described as a reasonable general minimum—not a guarantee that every kitchen is safe until the same date next year.
High use, heat, grease, movement, outdoor exposure, recurring faults, appliance changes, hose condition, ventilation problems or an unsafe finding can justify earlier checks or repairs. Stop using equipment that is known or suspected to be unsafe.
Choose what the appointment must achieve
Inspection, servicing, repair and commissioning are not interchangeable
Prepare a quotation without avoidable delay
Send six groups of information before requesting attendance
Postcode, kitchen type and access
Give the address, restaurant, takeaway, school, hotel or other setting, parking, opening hours and shutdown restrictions.
Fuel, meter or LPG arrangement
Send photographs of the supply, regulator, isolation, visible pipework and any bulk tank or cylinder storage.
Every item and data plate
List make, model, serial, input and fuel for each appliance, including movable, spare or disconnected equipment.
Extraction, make-up air and interlock
Provide canopy, fan, permanent ventilation, interlock-panel and previous airflow or commissioning information.
Records, faults and alterations
Attach the last gas record, service sheets, unsafe notices, repairs, new equipment and any access limitation.
Exact words and deadline
Forward the landlord, insurer, council, franchise, venue or contract requirement so the proposed record can be checked.
If gas may be escaping
Use the emergency route for the actual fuel
Do not operate electrical switches or use flames. For mains gas in Great Britain call the National Gas Emergency Service on 0800 111 999. For LPG, follow the supplier's emergency instructions for the cylinders, tank and installation.
If there is fire, an uncontrolled release, immediate danger or any doubt, evacuate and call 999. Upkeepone's routine enquiry numbers are not emergency reporting services.
Postcode-qualified commercial catering enquiries
Where Upkeepone can consider commercial-kitchen gas work
Regular work covers London, Essex and Kent. Hertfordshire, Surrey, Buckinghamshire, Berkshire and Sussex can be considered when the right commercial catering gas or LPG trade is available. Other UK areas are considered by request after the postcode, kitchen or unit, fuel, appliances, ventilation, work and engineer categories have been checked.
