Restaurant and Takeaway Gas Safety Certificate London
Arrange suitable gas safety paperwork for a London restaurant, takeaway, cafe, pub, hotel or dark kitchen. This guide explains when a CP42 route may apply, what an inspection can cover, why ventilation and appliance details matter, and what to send for a useful quotation.
Describe the kitchen, not only the certificate name
A two-appliance cafe, a high-output takeaway line and a hotel kitchen with separate boiler plant are different jobs. A clear inventory helps identify the correct commercial catering, LPG, heating or pipework competence and reduces the risk of an unsuitable visit.
- Full address, postcode, business type and trading hours.
- Natural gas or LPG, plus every appliance and data plate.
- Reason for the record, requested wording and deadline.
- Extraction, interlock, access, shutdown and parking notes.
Which gas safety route does your food business need?
The wording on an insurer's checklist or lease can be helpful, but the physical installation determines the work. Use these four routes to identify the information that should accompany your enquiry.
Fixed commercial kitchen
A restaurant or takeaway with fixed fryers, ranges, ovens, grills, tandoors or water boilers will commonly need commercial catering competence. List every appliance, including equipment that is disconnected, unused or awaiting installation.
Kitchen plus heating plant
A catering record does not automatically cover a commercial boiler or plant room. Identify heating and hot-water equipment separately, including where it serves flats, hotel rooms or another part of a mixed-use building.
LPG or mixed fuel
Cylinder or bulk LPG changes the supply arrangement and required competence. State whether LPG is permanent, seasonal, external or used alongside mains gas, and include the tank or cylinder location and supplier details.
Mobile or temporary catering
Vans, trailers, stalls, pop-ups and event kitchens have different operating and access conditions from fixed premises. Give the unit type, pitch, setup date, cylinder storage, hoses, regulators and venue requirements.
What “restaurant gas safety certificate” usually means
Customers often use this phrase when they need evidence for an insurer, landlord, managing agent, licence file, opening checklist or planned maintenance record. It is a useful starting point, but it is not the name of one universal statutory document for every commercial food business.
The agreed record should identify the premises, appliances or installation section inspected, findings, defects, limitations and the engineer or registered business responsible for the work. It should be read with any service sheet, commissioning record, repair invoice or ventilation evidence relevant to the site.
If the requester has supplied a form or exact wording, send it before booking. That makes it possible to confirm whether the proposed visit can provide the evidence they expect.
CP42 is common, but not automatic
CP42 is widely used for commercial catering gas work in fixed kitchens. A request may still need another route where it includes LPG storage, mobile catering, a commercial boiler, new pipework, commissioning or equipment outside the catering category.
Read the CP42 commercial catering guideWhat the visit may cover
The actual checks depend on the equipment, accessibility, fuel and booked work. The quotation should define the scope rather than leaving the customer to infer it from a certificate name.
Appliances and safety devices
The visit may include accessible commercial cooking appliances, flame supervision, ignition, controls, stability, condition and signs of unsafe operation. Each appliance should be identified so omitted or inaccessible equipment is clear.
Gas supply and isolation
Accessible installation pipework, appliance connections, local isolation, emergency controls and signs of deterioration may form part of the agreed inspection. Extensive commercial pipework, testing, purging or alteration can require a separate scope.
Combustion and flueing
Where relevant to the appliance, the engineer may assess safe combustion, combustion products and flue arrangements. Appliances that depend on the room or extraction system for safe operation need suitable operating conditions during the visit.
Ventilation and interlocks
Make-up air, mechanical extraction and a gas interlock may be relevant to safe use. Their presence does not mean the whole extraction system, duct cleaning, fire resistance or design performance is included in the gas record.
Gas appliances, extraction and make-up air must work together
Commercial cooking produces heat, fumes and vapour. HSE guidance explains that kitchens need effective ventilation and that adequate make-up air is especially important for gas-fired appliances. Poor air supply or incorrect flueing can contribute to incomplete combustion and carbon monoxide accumulation.
Do not block air inlets, alter canopies, move appliances, change fan speeds or bypass an interlock without competent assessment. A kitchen that operated safely before a refit may need reassessment after changes to equipment, doors, ceilings, extract fans or the layout.
A gas safety visit is not automatically an extraction-cleaning certificate, fire-risk assessment or planning approval. Ask who is responsible for each record and keep the current documents together.
Tell us before the visit if:
- The extract or supply fan is faulty, noisy or recently replaced.
- The gas shuts off when the fan stops, or the interlock has been bypassed.
- Appliances have been moved, added or converted.
- Staff report headaches, soot, unusual flames or combustion smells.
- The kitchen also uses charcoal, wood or another solid fuel.
Operator, landlord and contractor duties need a clear boundary
Food premises often involve several parties. Put the allocation in writing, share the relevant records and confirm who can authorise access, shutdowns and repairs.
Food-business operator or employer
Manage workplace risks, provide safe operating procedures, report faults, arrange maintenance for controlled equipment and ensure staff know the emergency arrangements. Keep the appliance inventory and trading constraints current.
Landlord or managing agent
Clarify responsibility for landlord-owned pipework, plant, shared services, building ventilation and access to common areas. A lease clause should be read alongside the real control of the equipment and premises.
Maintenance provider
Define which appliances and systems are under contract, the maintenance interval, attendance route, exclusions and how urgent defects are escalated. A routine service contract should not be assumed to include every certificate.
Gas engineer or registered business
Confirm the engineer is Gas Safe registered for the fuel and relevant commercial catering or other work category. Registration for one type of gas work does not prove competence for every appliance or installation.
Do not wait for an opening deadline to discover a maintenance problem
HSE says hospitality and catering employers must keep gas appliances, flues, pipework and safety devices in a safe condition. Inspection periods can vary with the equipment and its use and should follow manufacturer recommendations; HSE describes annual inspection as a reasonable general minimum.
That is not a promise that every certificate lasts for exactly twelve months or that an annual visit is always enough. High usage, grease, heat, vibration, repeated ignition problems, equipment changes or an earlier defect may justify more frequent service or inspection.
Build the renewal date into the maintenance calendar. Allow time for access, parts, repairs and any return evidence before an insurer, landlord or reopening deadline.
Keep one evidence file
- Current appliance and fuel inventory.
- Gas safety records and service sheets.
- Repair and commissioning evidence.
- Ventilation, interlock and extraction records.
- Lease or management responsibility schedule.
- Emergency contacts and staff instructions.
Use the inspection as one part of a complete handover
A certificate should not be used to fill gaps in commissioning, maintenance or responsibility records. These are the common points where a food business needs a wider evidence check.
New opening or takeover
Ask for the previous gas records, equipment manuals, service history, extraction evidence and defect status. Verify the installed appliance list instead of relying on a former operator's schedule.
Kitchen refit
Record every added, removed, moved or converted appliance and any change to pipework, fans, canopies or make-up air. New installation and commissioning work should be identified separately from a periodic safety inspection.
Lease or operator handover
Agree who owns the appliances, who controls the gas supply and ventilation, what defects remain, and who pays for repair. Keep signed inventories and records with the handover documents.
Insurer or managing-agent renewal
Send the exact request and deadline. Check whether the recipient expects a catering record, boiler evidence, LPG information, service sheets or proof that previous remedial work was completed.
Prepare the kitchen before the engineer arrives
The engineer needs safe, practical access and accurate information. A well-prepared visit is easier to scope and less likely to leave avoidable limitations.
- Choose a time outside peak service where possible.
- Make appliance fronts, isolation points and plant areas accessible.
- Have extraction and interlock systems available to operate.
- Provide previous records and details of known defects or changes.
- Ensure a responsible contact can answer questions and authorise decisions.
Read the scope, findings and limitations before filing the certificate
Check that the address, fuel and appliance list are correct. Read every defect, advisory note, limitation and action taken. If an appliance was not tested or part of the installation was inaccessible, decide how that gap will be resolved rather than treating the document as blanket approval.
Where remedial work is required, use a suitably qualified Gas Safe registered engineer for the relevant category. Keep repair invoices, parts information and any return inspection or updated record. Provide the final evidence to the insurer, landlord or other requester only when it accurately reflects the completed work.
Five questions to ask
- Exactly what was inspected?
- What was excluded or inaccessible?
- Can every appliance remain in use?
- What repair or maintenance is advised?
- Is a return visit or revised record needed?
Stop normal work, keep people away, avoid flames and electrical switches, leave the affected area and follow the premises emergency plan. For a mains-gas or carbon monoxide emergency, call the National Gas Emergency Service on 0800 111 999. For LPG, call the supplier emergency number. Call 999 if there is a fire or immediate danger. Do not use this enquiry form for an emergency.

Restaurant and takeaway gas safety FAQs
What is a restaurant or takeaway gas safety certificate?
It is a customer term for suitable gas safety paperwork covering an agreed part of a commercial food premises. The record may relate to catering appliances, pipework, controls, flues and ventilation considerations, but there is no single certificate that automatically covers every gas, extraction, fire-safety and maintenance duty. The quotation should state the exact scope and record to be issued.
Do restaurants and takeaways need a CP42 certificate?
CP42 is commonly requested for commercial catering gas appliances in fixed kitchens, but the right record depends on the equipment, fuel and reason for the request. A boiler, LPG cylinder installation, mobile catering unit or new pipework may need a different or additional work category. Send the wording from your insurer, landlord, managing agent or opening checklist before booking.
How often should commercial kitchen gas equipment be inspected?
The interval should follow the manufacturer instructions, the equipment, its level of use, operating conditions, previous findings and competent advice. HSE says annual inspection is a reasonable general minimum for hospitality and catering gas equipment, while recognising that intervals may vary. A heavily used kitchen or a fault may require earlier attention.
Does the gas safety visit include servicing and repairs?
Not unless the quotation says so. A safety inspection records findings for the agreed scope. Cleaning, servicing, fault diagnosis, replacement parts, alteration, commissioning, testing and purging of new pipework, and return visits after remedial work are separate tasks. Ask for the included work, exclusions and remedial process in writing.
Will the certificate cover the kitchen extraction system?
Not automatically. The engineer may consider ventilation, make-up air and any relevant gas interlock when assessing safe appliance operation, but that does not certify the full extraction design, cleaning condition, fire risk, duct route or planning compliance. Extraction design, cleaning and fire-safety evidence may require separate competent contractors and records.
Who is responsible for gas safety in a leased restaurant?
Responsibility can be shared between the food-business operator, employer, landlord, managing agent and maintenance provider. The lease and management agreement should identify who controls the appliances, installation pipework, plant, ventilation, access and repairs. The operator still needs to manage workplace risks and should not assume that a landlord-arranged visit covers tenant-owned catering equipment.
What information should I send for a restaurant gas quotation?
Send the full address and postcode, business type, opening or renewal deadline, reason for the request, fuel type, complete appliance list, photographs of data plates, ventilation and interlock details if known, previous records, recent changes or faults, kitchen access, parking or loading restrictions, and the contact who can authorise work.
Can the inspection be completed while the kitchen is trading?
Sometimes, but safe access and appliance testing may interrupt cooking or require equipment to be available in a particular condition. A crowded service period is rarely the best time for a complete visit. Give trading, prep and cleaning hours in advance so access, shutdowns and the person meeting the engineer can be planned.
What happens if the engineer finds a defect?
The record should identify the finding, affected equipment, action taken and any limitation. Do not treat the visit as a pass label if remedial work is listed. Ask what must remain out of use, arrange repair by a suitably qualified Gas Safe registered engineer, keep the repair evidence and confirm whether a return inspection or revised record is needed.
What should I do if I smell gas in a restaurant or takeaway?
Treat it as an emergency. Keep people away, avoid flames and electrical switches, leave the area and follow the premises emergency procedure. For a mains-gas or carbon monoxide emergency, call the National Gas Emergency Service on 0800 111 999. For LPG, use the supplier emergency number. Call 999 where there is fire or immediate danger, and do not restart equipment until competent advice confirms it is safe.
