Commercial gas certificate expired or near expiry? Start here
If a landlord, insurer, managing agent, tenant or compliance team says your commercial gas paperwork has expired, first confirm which document they mean. “Commercial gas certificate” is an informal umbrella term, not one universal record with one expiry rule.
The right next step depends on the premises, gas equipment, fuel, purpose of the previous visit and the evidence now being requested. A restaurant kitchen, office boiler, LPG installation and commercial pipework test may require different engineer competencies, checks and records.
Need to renew or identify the right commercial gas record?
Send the Greater London site postcode, business use, fuel type, appliance list, wording from the person requesting the document, access restrictions and deadline. London Landlord Certifications can review the enquiry and confirm the appropriate booking route by phone or email.
What to do when commercial gas paperwork has expired
1. Read the document and the request
Check the exact title, inspection date, equipment listed, site address, findings and any stated review or renewal date. Then compare it with the wording in the insurer’s email, lease clause, landlord request, tender requirement or internal compliance schedule. Do not assume that the last document is automatically the document now required.
2. Check what has changed at the premises
Commercial gas paperwork records an agreed scope at a point in time. It may no longer answer the current question if appliances have been added, replaced, moved or removed; the fuel has changed; a new tenant has taken occupation; the business use has changed; repairs followed an unsafe finding; or responsibility has moved between landlord and tenant.
3. Separate an expired document from an unsafe appliance
An old or disputed record does not, by itself, establish the condition of every appliance today. Equally, a recent record should not be used to dismiss warning signs or a known defect. HSE guidance says not to use an appliance that is known or suspected to be unsafe. If you suspect a natural-gas leak, turn off the supply if it is safe to do so and call the National Gas Emergency Service on 0800 111 999; for LPG, contact the LPG supplier.
Read HSE gas safety guidance for employers.
4. Identify the likely inspection or record route
Describe the site and equipment if you do not know the form name. Commercial catering equipment may lead to CP42-style catering documentation; a non-domestic installation request may refer to CP17; commercial testing, purging or commissioning may involve CP15 or CP16; and boiler plant, LPG or mobile catering equipment can require a different scope. These names are not interchangeable and one visit does not automatically include every possible appliance, control, ventilation assessment or specialist test.
- CP42 commercial catering gas certificate
- CP17 commercial gas safety certificate
- CP15 and CP16 commercial gas records
- Commercial boiler servicing and plant enquiries
- Commercial LPG gas certification enquiries
5. Arrange access around the agreed scope
Tell the provider about locked plant rooms, landlord-controlled areas, roof or basement access, security procedures, permits, inductions, parking or loading restrictions and the person authorised to provide access. For kitchens and other trading premises, explain opening hours and periods when equipment can be isolated. The likely disruption depends on the agreed work, site layout and findings, so it should be discussed rather than promised in advance.
6. Keep the new record with its scope and findings
When the visit is complete, check that the document identifies the premises, date, equipment or work covered and any observations or limitations. Keep related remedial invoices, follow-up records and the requester’s original wording together. A new date is useful only when the record actually addresses the requirement.
Does every commercial gas certificate expire after 12 months?
No single 12-month rule applies to every document described as a commercial gas certificate. The relevant duty, inspection frequency and evidence depend on the installation, premises and purpose of the work. Many businesses plan annual inspections because of manufacturer guidance, industry practice, an insurer, a lease or an internal compliance schedule.
For hospitality and catering equipment, HSE says inspection periods may vary with the equipment and its use and should follow manufacturer recommendations, while annual inspection is a reasonable general minimum. That guidance should not be turned into a claim that every commercial record is a universal statutory annual certificate.
For the detailed validity question, use the separate commercial gas certificate validity guide.
What can make paperwork unsuitable before the planned renewal date?
- A new, moved or replacement gas appliance.
- A change between natural gas and LPG, or a mixed-fuel arrangement.
- A new tenant, lease, managing agent or person controlling the equipment.
- A change of business use, kitchen layout, extraction or ventilation arrangement.
- A defect, disconnection, repair or follow-up visit after the last record.
- An insurer, landlord, buyer or compliance team asking for different evidence.
- The previous inspection excluding equipment now included in the request.
What information helps with a commercial gas renewal enquiry?
A clear first enquiry reduces the risk of arranging the wrong attendance or discovering an access problem when the deadline is close. Provide:
- the full site address and postcode;
- the business or premises type;
- the exact certificate or report wording requested;
- the previous record type and date, if known;
- natural gas, LPG or mixed fuel;
- an appliance and plant list, including catering equipment, boilers, heaters and water heaters;
- anything changed, repaired or added since the previous visit;
- the site contact, trading hours and access restrictions;
- the deadline and reason for it; and
- the number of sites if the enquiry covers a portfolio.
If you hold a previous record, written request or data-plate photographs, mention them in the enquiry and ask how to send supporting files securely. The website enquiry form does not accept uploads.

Commercial gas certificate expiry FAQs
Can a business keep trading after commercial gas paperwork expires?
An expiry date alone does not decide whether every business can trade. Check the equipment condition, the document requested, lease, insurance and risk-control requirements. Do not use an appliance known or suspected to be unsafe, and obtain competent advice where safety or continued operation is uncertain.
Can an expired commercial gas certificate be extended?
A date should not simply be changed to extend old evidence. Confirm what record is required now and arrange the appropriate current inspection, service, test or other work for the agreed scope.
Do I need the same record if the equipment has changed?
Not necessarily. New, replaced, moved or removed equipment can change the suitable scope and documentation. Send an up-to-date appliance list and explain what changed before the visit is booked.
Is a commercial gas safety inspection the same as servicing?
No. An inspection or safety record and planned servicing have different purposes, even where some checks overlap. Confirm whether the request is for evidence of an inspection, maintenance, repair, testing, commissioning or a combination of work.
What should I send when I do not know the certificate name?
Send the postcode, business type, fuel, appliance list, previous record date, reason for the request, deadline and access details. Include the exact wording used by the landlord, insurer, agent or compliance team.
Arrange the right next step
Do not wait for a generic “certificate” appointment to discover that the site needs a different record or specialist scope. Send the premises and equipment details first so the enquiry can be reviewed.
