CP42 Commercial Catering Gas Certificate London
Arrange commercial catering gas safety paperwork for a London restaurant, cafe, takeaway, pub, hotel or workplace kitchen. This guide explains the likely CP42 scope, ventilation and interlock questions, business responsibilities, inspection timing and the details needed for a useful quotation.
CP42 is commonly used for a commercial catering gas safety record. The useful starting point is not the code alone: send the kitchen appliance list, natural gas or LPG, canopy and interlock details, business hours, previous record, known faults and the exact wording from the person requesting the certificate.
Describe the cooking line and the kitchen, not only “CP42”
A three-appliance cafe is a different visit from a high-volume takeaway, hotel banqueting kitchen or food hall unit. Send enough detail to identify the equipment, fuel, ventilation relationship, access window and evidence required. That helps the enquiry reach an engineer with the relevant commercial catering competence.
- Full address, postcode, business type and responsible kitchen contact.
- Every gas appliance, fuel type and data-plate photographs where available.
- Extraction, make-up air, interlock, recent alteration and known fault details.
- Previous records, requester wording, access restrictions and required date.
When CP42-style catering gas paperwork may be relevant
This route is intended for professional kitchens using gas-fired catering equipment. It can support routine safety management and requests from insurers, landlords, facilities teams or commercial clients, but the eventual record should identify the actual appliances and safety arrangements covered.
Restaurant or cafe
Where a fixed cooking line includes commercial ovens, ranges, fryers, grills or specialist appliances and the operator needs current gas-safety evidence.
Takeaway or dark kitchen
Where long operating hours, concentrated heat, several high-use appliances and restricted access make accurate planning especially important.
Pub, bar or hotel
Where the catering kitchen sits alongside guest areas, accommodation, events, hot-water plant or other gas equipment that may require a separate scope.
School, care or community kitchen
Where an organisation needs clear records, competent attendance and coordination around service users, safeguarding, meal times or site induction.
Landlord or tenant handover
Where the parties need to establish appliance ownership, incoming gas services, ventilation responsibility and the condition of an existing kitchen.
Food hall or managed site
Where a tenant kitchen connects with landlord systems, shared extraction, common isolation controls or access managed by a facilities team.
What a catering gas safety visit may consider
Within the agreed scope, the engineer may consider accessible commercial catering appliances, gas connections and isolation, controls, flame supervision and safety devices, appliance stability and condition, combustion or flue arrangements where relevant, and whether the available ventilation and interlock arrangements support safe operation.
The record should identify the premises, appliances checked, work completed, results, observations and any limitations. Equipment that is inaccessible, disconnected, not available for safe operation or outside the quotation should not be assumed to have passed.
The record is only as useful as its scope
A certificate label cannot compensate for a missing fryer, an unlisted tandoor, inaccessible isolation, a changed canopy or a second kitchen that was never mentioned. Compare the completed record with the current asset list before placing it in the compliance file.
The canopy, make-up air and gas supply must work as a safe system
Gas-fired catering appliances need sufficient air for combustion and a kitchen needs effective removal of heat, fumes and combustion products. HSE guidance highlights the importance of adequate make-up air and, where mechanical ventilation serves the appliances, an appropriate relationship between airflow and the gas supply.
Important: a catering gas record does not automatically certify the design, airflow rate, hygiene or fire condition of the whole ventilation system. A competent ventilation contractor or designer may be needed for separate assessment, measurement, cleaning or remedial work.
Responsibility follows control of the kitchen and its systems
The food business operator or employer normally controls daily appliance use, staff procedures and the reporting of faults. A commercial landlord may own the incoming pipework, meter position, shared isolation or building ventilation. A tenant may own the catering line, while a managing agent or facilities provider coordinates maintenance and access.
Read the lease, asset list and maintenance agreements. Agree who controls the appliances, pipework, canopy, interlock, make-up air and any shared plant. The responsible parties should exchange previous records, give the engineer safe access, retain the completed evidence and act on findings.
Before a new tenant opens
Do not assume the previous operator's record covers a changed cooking line. Record which appliances remain, what has been removed or installed, who altered the gas or extraction system, and whether commissioning, testing, servicing or ventilation work is still outstanding.
Annual inspection is a general minimum, not the whole maintenance plan
HSE says the periods between inspections may vary with the equipment and its use and should follow the manufacturer's recommendations, with annual inspection a reasonable general minimum. A busy cooking line may also need more frequent planned maintenance, cleaning or attention following faults and alterations.
Plan access around a working commercial kitchen
The engineer needs safe access to the appliances and associated controls. London kitchens often have limited loading, basement access, shared rear yards, security procedures and narrow gaps between food preparation and service, so agree the workable attendance window before booking.
- Provide a complete asset list, including make, model and location where known, plus clear data-plate photographs.
- Confirm natural gas, LPG or mixed fuel, and identify cylinders, bulk storage or mobile equipment separately.
- Make the canopy, extract controls, make-up air, gas interlock, emergency isolation and relevant plant accessible.
- Share the previous gas record, service reports, ventilation documents, warning notices and evidence of completed repairs.
- Explain new, moved, disconnected or out-of-use equipment and any recent gas, electrical or extraction alterations.
- Arrange the responsible kitchen contact, keys, induction, permits, parking or loading and access to landlord-controlled areas.
- Allow enough time before opening, insurance renewal or handover for limitations, further investigation and remedial work.
Several related tasks may need separate quotations
A CP42-style safety record should not be assumed to include full servicing or repair of every appliance, commercial pipework testing and purging, commissioning newly installed equipment, LPG storage assessment, duct cleaning, ventilation design, airflow measurement, fire-suppression work or electrical inspection.
Tell us what outcome is needed, not only the certificate code. If the kitchen has a boiler or water heater outside the cooking line, a mobile catering unit, a landlord plant room or a newly modified installation, identify it separately so the correct commercial route can be considered.
Service, repair or certificate?
If an appliance is unreliable, producing unusual flames, repeatedly shutting down or showing a fault code, say so before attendance. A routine record is not a substitute for fault diagnosis or remedial work, and equipment suspected to be unsafe should not remain in use.
Read the appliance schedule, findings and limitations
Check that the record has the correct business and site address, date, engineer details, fuel, appliance schedule, work undertaken, result, observations and any limitations. Compare it with the current kitchen rather than filing it unread. An omitted or inaccessible appliance is not covered merely because the document is headed CP42.
Where action is required, identify who is responsible, arrange the appropriate competent contractor and keep completion evidence with the original record. The operator, landlord and facilities contact should each receive the findings relevant to systems they control.
Keep a connected evidence file
Store gas records with appliance services, repair invoices, commissioning documents, extraction maintenance and cleaning records, interlock work, risk assessments and staff procedures. Together they explain how the kitchen is being kept safe more clearly than one certificate in isolation.
Check the engineer's relevant commercial catering categories
Gas work in restaurants and other workplaces must be completed by a Gas Safe registered engineer qualified for the fuel, commercial catering appliances and activity involved. Check the engineer on the Register and the categories shown on the Gas Safe ID card; domestic registration does not establish competence for every commercial kitchen task.
If the enquiry includes LPG, mobile catering, large commercial pipework, testing and purging, specialist appliances or separate heating plant, disclose that before booking because additional competence or a different work scope may be needed.
Do not wait for a certificate appointment. Avoid flames and electrical switches, move people away from danger and call the National Gas Emergency Service on 0800 111 999 for mains natural gas. For LPG, contact the supplier or use the emergency number for the installation.
Use current sources for kitchen duties, ventilation and competence
These primary sources explain catering gas maintenance, inspection timing, kitchen ventilation, employer responsibilities and Gas Safe registration. The engineer and dutyholder still need to apply the current requirements to the particular installation.

CP42 commercial catering gas certificate FAQs
What is a CP42 commercial catering gas certificate?
CP42 is a name commonly used for a commercial catering gas safety record covering an agreed group of gas-fired cooking appliances and related safety arrangements. The label does not create one identical inspection for every kitchen, so the appliance list, fuel, ventilation or interlock arrangements, site use and requester wording should be confirmed before booking.
Which businesses may need CP42-style catering gas paperwork?
Restaurants, cafes, takeaways, pubs, hotels, schools, care homes, community venues, production kitchens and other workplaces using commercial gas catering appliances may need suitable safety and maintenance evidence. The responsible business, landlord, facilities team, insurer or client may ask for a CP42-style record as part of its compliance file.
What can a CP42 catering gas visit cover?
The agreed visit may consider accessible commercial catering appliances, their gas connections and controls, flame supervision and safety devices, combustion or flue arrangements where relevant, and the relationship with the kitchen ventilation or gas interlock. The record should state the actual scope, findings and limitations. Servicing, repairs, duct cleaning and ventilation design work are separate unless expressly included.
How often should commercial catering gas appliances be inspected?
HSE says inspection periods can vary with the equipment and its use and should follow manufacturer recommendations, while annual inspection is a reasonable general minimum. A suitable plan should also consider operating hours, condition, previous defects, risk assessment, insurer or lease requirements and competent advice. Do not rely on the CP42 label alone as an expiry rule.
Does a CP42 check include the kitchen extraction system?
A catering gas engineer may need to consider whether ventilation and any gas-supply interlock support safe appliance operation, but a CP42 visit does not automatically certify the design, airflow performance, cleanliness or fire safety of the whole extraction system. Tell us about the canopy, fans, make-up air, interlock and recent changes so any separate specialist work can be identified.
Is CP42 the same as CP17, CP15 or CP16?
No. CP42 normally relates to commercial catering appliances and kitchen gas safety arrangements. CP17 is commonly requested for a wider non-domestic premises or installation record, while CP15 and CP16 are associated with defined commercial pipework testing, purging or commissioning work. One site may need more than one scope.
Does CP42 include a service or repair of each appliance?
Not automatically. A safety record, planned appliance service, fault diagnosis and repair are different tasks. If an oven, fryer, range, grill, tandoor, water heater or other appliance also needs servicing or repair, list the make, model and known issue so it can be considered in the quotation.
What information should I send for a CP42 quotation?
Send the full address and postcode, type of food business, natural gas or LPG, complete appliance list, make and model where known, canopy and interlock details, previous record, known faults, alterations, kitchen access times, site contact, parking or loading restrictions, requester wording and deadline. Photographs of appliance data plates can help.
Who is responsible for catering gas safety in leased premises?
Responsibility may be shared. The operator or employer normally controls the day-to-day use of kitchen equipment, while a landlord or managing agent may retain responsibility for incoming pipework, shared plant or the building ventilation system. Check the lease, equipment ownership and maintenance agreements, then agree access and scope before attendance.
What should I do if I smell gas or an appliance appears unsafe?
Do not wait for a routine certificate visit. Stop using equipment you know or suspect is unsafe, avoid flames and electrical switches, move people away from danger and call the National Gas Emergency Service on 0800 111 999 for mains natural gas. For LPG, contact the supplier or use the emergency number for the installation.
