Commercial natural gas and LPG certification
Commercial Gas Certificate
Arrange a commercial gas safety inspection and written certificate for a business premises, managed property or hospitality site.
Send the full postcode, natural gas or LPG supply, appliance list, meter details, site use and access hours. We check that the engineer’s Gas Safe competence matches the work before confirming attendance.
The practical answer
What is a commercial gas certificate?
A commercial gas certificate is the written record issued after an appropriately qualified engineer completes the agreed gas safety checks at business or non-domestic premises. It should identify the site, equipment checked, test date, engineer and findings within that scope.
There is no single certificate format or inspection rule that fits every commercial premises. A restaurant kitchen, office boiler room, workshop and LPG installation can involve different fuels, appliances, risks and engineer competencies. Tell us who has requested the document—such as a landlord, facilities team, insurer or local authority—and what they expect it to cover.

| Commercial gas meter check only | From £130 + VAT£156 including VAT | A check focused on the gas meter and the agreed record. This does not include safety checks on commercial appliances. |
The VAT-inclusive figures use the standard 20% rate. All amounts are starting prices; the quotation will confirm the total for your premises.
What can change the quote?
Appliance type and number, natural gas or LPG, the inspection required and site access affect the price. Tell us about parking, travel restrictions or work needed outside normal hours when you enquire.
Work quoted separately
Servicing, repairs, replacement parts, installation work and specialist testing or purging are separate unless the written quotation includes them.
Find the right service
Which commercial gas inspection do you need?
Choose the section that best matches your equipment. If the premises has both a kitchen and a separate heating system, include both in your enquiry so we can agree the scope.
Commercial kitchens
For restaurants, takeaways, pubs and other premises with gas cooking equipment. Tell us which appliances you use and whether the supply is natural gas or LPG.
Commercial boilers and heating
If the enquiry concerns a boiler or heating plant, send the make, model and output if known. Mention any other gas equipment at the premises so we can agree what the visit should cover.
Fixed commercial LPG
For a fixed business site using LPG cylinders or a bulk tank. Describe the connected appliances and supply arrangement so we can check which parts of the installation can be included.
Mobile catering LPG
For a catering van or trailer using LPG. Send the vehicle or trailer details, appliance list and the postcode where it will be available for inspection.
Gas Safe registration alone is not a blanket qualification for every commercial job. The back of an engineer’s current ID card shows the work categories they may undertake. That is why the appliance list and fuel type must be checked before the visit.
Agreed inspection scope
What does a commercial gas safety inspection cover?
The quotation needs to identify the appliances and installation areas being inspected. The engineer selects the checks that apply to that equipment, fuel and operating arrangement; a kitchen and a boiler room do not have an identical checklist.
- Operation and condition of the listed appliances
- Safety devices and accessible isolation controls
- Combustion and flue arrangements, where relevant
- Air supply and ventilation needed for safe use
- The agreed meter and accessible pipework scope
- Connections and visible installation concerns
- Catering ventilation and gas interlocks, where applicable
- Findings, limitations and necessary safety action
An inaccessible appliance or incomplete test cannot be treated as a satisfactory result. Tell us about locked rooms, concealed pipework or equipment awaiting repair so the limits of the visit can be discussed beforehand.
Plan access and any interruption to work
Some checks require appliances to run; others may require equipment or the gas supply to be switched off. Agree the access window before the visit, including any effect on cooking, heating or hot water. Have a site contact available with the necessary keys and permissions.
UK workplace guide
Commercial gas safety is an ongoing management duty
A certificate can support your records, but it does not replace risk assessment, suitable maintenance or prompt action on defects. The responsible person should set a regime that fits the premises and equipment.
Maintain relevant appliances, flues, pipework and safety devices in a safe condition.
Check current Gas Safe registration and the categories that match the actual commercial work.
Use equipment, risk, manufacturer and industry guidance rather than assuming one timetable suits every site.
Keep the record, control unsafe equipment and arrange competent remedial work when required.
For hospitality and catering premises, HSE says inspection periods can vary with the equipment and its use and should follow manufacturer recommendations; it describes annual inspections as a reasonable minimum in general. Commercial kitchens also need adequate ventilation and suitable arrangements for gas-fired equipment.
Avoid scope gaps
Certificate, service and repair are different jobs
State the required outcome when booking. Combining the services may be possible, but the certificate price covers only the testing and record described in the quotation.
Safety check and certificate
Tests the agreed appliances and installation points for safety-related matters and produces the relevant written record.
Planned service
Maintains specified equipment using the applicable service procedure. It may involve cleaning, adjustment or service parts not included in a certificate check.
Repair or installation
Corrects a fault, replaces components or alters the installation. Parts, labour and any return attendance need separate authorisation.
Specialist work needs its own agreed scope
- Testing and purging: the quote must allow for any tightness testing needed to complete the selected inspection. A separate installation tightness test, purging or commissioning job needs assessment and a quotation for that work.
- Kitchen extraction: ventilation and interlocks affecting appliance safety must be considered where relevant. Duct cleaning, extraction design, airflow commissioning and electrical alterations are not automatically included.
- LPG supply: an appliance inspection does not automatically assess the whole bulk tank, buried pipework or supplier equipment. Confirm the inspection boundary and who is responsible for each part of the system.
For bulk LPG premises, see HSE guidance on tanks, pipework and valves.
Booking process
From appliance list to completed commercial gas record
Describe the site
Send the postcode, business use, fuel, appliance list, meter position, access hours and deadline.
Confirm scope and price
We confirm the engineer category, equipment list, inspection limits, price and document to be supplied.
Engineer attends
The engineer carries out the agreed checks, records the results and explains any immediate safety action.
Receive the record
Keep the report and any warning notice. If faults need attention, agree the remedial work and any checks needed afterwards.
Inspection records and findings
Which commercial gas report will you receive?
Confirm the document needed when the inspection is quoted. If a landlord, insurer or facilities team has specified a form, send their request with your enquiry. The following references describe different records; none is a certificate for every commercial gas installation.
| Form | What it relates to |
|---|---|
| CP42 | A commercial catering inspection covering the kitchen environment and its gas appliances. |
| CP17 | A non-domestic gas installation safety report, where appropriate to the inspection being arranged. |
| CP44 | A mobile catering vehicle or trailer safety check. It is not a general name for fixed-premises LPG paperwork. |
Reference names can be checked in the CORGI non-domestic form catalogue. We confirm the appropriate documentation for the booked installation before attendance.
What to look for in the record
Check the site, inspection date, engineer details, fuel, equipment covered and recorded results. Read any exclusions, incomplete checks, defects and recommended action. Keep the report with your service history and evidence of subsequent repairs.

Common questions
Commercial gas certificate FAQs
Answers to common questions about booking, prices, gas safety duties and inspection outcomes.
How much does a commercial gas certificate cost?
The starting price is £155 + VAT (£186 including VAT) for one commercial gas appliance, a meter check and the agreed record. The final quote depends on the equipment, fuel, premises and access.
What is included in the £155 + VAT starting price?
It covers safety testing for one commercial gas appliance, the meter check and completion of the agreed record. Servicing, repairs and replacement parts are included only if they are listed in your quotation.
How much is each additional commercial gas appliance?
Each appliance beyond the one included in the commercial gas certificate price starts from £45 + VAT (£54 including VAT). The appliance type and any additional work still need to be confirmed.
How much is a commercial gas meter check only?
A meter-only check starts from £130 + VAT (£156 including VAT). It does not cover the safety of commercial gas appliances, so tell us which document has been requested before booking.
Do you provide commercial LPG certificates?
Commercial LPG inspections start from £155 + VAT (£186 including VAT), with the scope agreed for the installation. Send details of the cylinders or bulk supply and connected appliances so we can confirm the required competence and availability.
Does every business need an annual commercial gas certificate?
There is no single certificate rule that applies identically to every commercial site. Businesses must manage workplace gas safety and keep relevant equipment in a safe condition. The inspection and maintenance schedule should reflect the equipment, its use, the risk assessment, manufacturer guidance and any landlord, insurer or industry requirement. HSE says annual inspection will generally be a reasonable minimum for hospitality and catering equipment, while the correct interval still depends on the equipment and use.
Why do you need the appliance type before confirming the booking?
Commercial gas work is divided into competence categories. The engineer must be Gas Safe registered and qualified for the particular fuel and equipment, such as commercial heating, commercial catering or LPG. Appliance data-plate photographs help us check the required category before attendance.
Is a commercial gas safety check the same as a service or repair?
A safety inspection records the condition of the agreed equipment at the time of the visit. Servicing follows a maintenance procedure, while repairs address identified faults. Ask for any combined work to be itemised in the quotation, including specialist testing or extraction work where needed.
What happens if a commercial gas appliance is unsafe?
Unsafe findings are recorded and explained; a warning notice may also be issued. Follow the engineer’s instructions and do not use equipment identified as unsafe. Repairs and any return checks need to be agreed separately. Receiving inspection paperwork is not confirmation that an unsafe appliance can be used.
What should I send for an accurate commercial gas quote?
Send the premises type and full postcode, natural gas or LPG, every appliance and its location, data-plate photographs where possible, meter details, opening hours, access or parking restrictions, the last certificate or service record and the deadline. Also explain who needs the document and why.
