Commercial Gas Certificate Renewal Checklist London
Commercial gas certificate renewal is easier when the old record, expiry date, appliance list, fuel type and access arrangements are checked before the deadline. This is especially important for restaurants, cafes, shops, offices, landlords, managing agents and managed commercial buildings where access and paperwork can involve more than one person.
Need to renew a commercial gas certificate?
Use the main commercial gas enquiry route if the renewal involves CP42, CP17, CP15, CP16, commercial boiler paperwork, LPG, a managed site, a tenant handover or several commercial units. The correct route depends on what has changed since the last record.
When should a commercial gas certificate be renewed?
Many commercial sites renew gas records annually because landlords, insurers, managing agents, facilities teams or internal compliance files expect current paperwork. The right timing also depends on what the previous record says and whether any equipment or responsibility has changed.
Before the expiry date
Start before the old record expires where possible. This gives time to arrange access, check the correct certificate route and deal with any follow-up actions.
Before a lease or tenant handover
Commercial landlords and managing agents often need gas paperwork before a new tenant takes occupation, a lease completes or a handover pack is issued.
Before insurance renewal
If an insurer asks for current gas paperwork, copy their wording into the enquiry. The wording helps confirm whether the request is CP42, CP17, boiler, LPG or another record.
After appliance changes
New cooking appliances, boiler changes, plant room work, LPG changes or kitchen alterations can affect the renewal route. Mention what has changed since the previous certificate.
After a business change
A change from office to cafe, shop to food premises, or landlord-controlled equipment to tenant-controlled equipment can change what should be inspected.
When a local authority or agent asks
If the request came from a council, managing agent, landlord, insurer or facilities team, include their wording and deadline with the renewal enquiry.
A practical renewal timeline before the certificate expires
Commercial gas renewals are easier when the enquiry starts before the paperwork becomes urgent. A restaurant, cafe, shop, office, landlord unit or managed site may need time to confirm access, gather appliance details, check the correct certificate wording and share the completed paperwork with the right person.
If the renewal is linked to insurance, a lease, a tenant handover, a local authority request or a trading deadline, start earlier and copy the exact wording from the requester. That helps avoid booking the wrong commercial gas route.
Commercial gas renewal checklist before you enquire
- Previous gas certificate or record, if available.
- Expiry date and reason for renewal.
- Current appliance list, including boilers, water heaters, ovens, fryers, ranges, heaters, LPG equipment and plant room equipment.
- Fuel type: mains natural gas, LPG cylinders, LPG tank or mixed fuel.
- Whether the certificate wording requested is CP42, CP17, CP15, CP16, commercial boiler, LPG or not yet known.
- Any changes since the previous record, including new appliances, removed appliances, tenant changes or building works.
- Access contact, opening hours, key holder, parking/loading notes, induction requirements and plant room location.
- Who should receive the renewed paperwork: business owner, landlord, tenant, managing agent, insurer or facilities team.
Renewal depends on the commercial gas record needed
The word renewal can hide important detail. Before booking, check whether the site needs the same commercial gas record as last year or whether the insurer, landlord, agent or facilities team is asking for something more specific.
CP42 catering renewal
Restaurants, takeaways, cafes and commercial kitchens should confirm the current cooking appliance list, ventilation details, gas interlocks, trading hours and any equipment changes.
CP17 non-domestic renewal
Offices, shops, landlord units and managed buildings may need non-domestic installation or landlord-controlled equipment details, including plant-room access and facilities contacts.
CP15 or CP16 renewal
If CP15 or CP16 wording appears in an insurer, contractor, landlord or facilities request, send the wording exactly so the appointment route can be checked properly.
Commercial boiler or plant renewal
Boilers, water heaters, warm-air units, meters, flues and plant rooms may need keyholder, permit, roof or restricted-access details before a renewal appointment is confirmed.
LPG renewal
LPG cylinders, tanks, mobile catering setups and mixed-fuel premises should be identified early because the fuel type can affect competence, access and paperwork.
Combined renewal deadlines
Some businesses renew gas alongside electrical, fire, EPC or landlord compliance files. List everything needed so the enquiry can be planned around the real deadline.
What to attach before a renewal visit is confirmed
A renewal enquiry is easier to price and schedule when the key evidence is sent at the start. You do not always need the previous certificate, but it helps confirm the old wording, issue date, appliance list and any notes from the previous engineer. If it is missing, send practical site details instead.
Previous certificate or record
Attach the old CP42, CP17, CP15, CP16, LPG, boiler or site record if you have it. A clear photo is useful if the PDF is not available.
Current appliance list
List every known gas appliance, including equipment that has been added, removed, disconnected, unused or changed since the last visit.
Requester wording
Copy the wording from the insurer, landlord, managing agent, facilities team, local authority contact or lease document so the right route is checked.
Access and deadline
Send the key holder, opening hours, parking or loading notes, induction rules, plant room location and the date the renewed paperwork is needed.
What changed since the last commercial gas certificate?
The renewal is not only a date in the diary. A small change on site can affect the right certificate route, the time needed and who must provide access.
New or removed appliances
List any new, removed, disconnected or unused appliances. A previous record may not reflect the current site.
Different certificate wording
If this year’s request mentions CP42, CP17, CP15, CP16, LPG or boiler paperwork differently, include that wording.
Different tenant or site use
A new occupier, new food use, added kitchen equipment or changed landlord responsibility can alter the enquiry route.
Access restrictions
Restaurants, offices, schools, care settings, warehouses and managed buildings may all have different best attendance times and access rules.
Old remedial notes
If the previous record mentioned issues, send those notes. They help identify whether follow-up work or further information may be needed.
Multiple certificates
Commercial gas renewal may sit alongside electrical, EPC, fire alarm, emergency lighting or fire risk paperwork. List everything needed together.
If the commercial gas certificate has expired
If the record has already expired, do not hide that detail. State the expiry date, who is asking for the renewal, whether the site is trading and what deadline applies. An expired certificate may be linked to insurance, landlord paperwork, a facilities file, local authority contact or a tenant handover, so the urgency needs to be clear.
- Call if the business cannot wait for a normal response cycle.
- Send the old certificate or a photo of the paperwork if you have it.
- Explain whether the site is occupied, trading, vacant or due to open.
- Confirm who can provide access and whether any out-of-hours attendance is required.
- List any safety concerns or known appliance issues separately from the certificate request.
Renewing several commercial gas certificates
Letting agents, facilities managers, commercial landlords and property managers should send a structured renewal list. This avoids missed sites, unclear access and repeated back-and-forth.
Send a site list
Include each address, postcode, tenant or business name, old record date, expiry date and certificate type requested.
Group similar access
Separate sites with business-owner access from managed buildings, keys, reception access, security checks or plant room inductions.
Flag the deadlines
Mark which renewals are urgent, which are routine and which depend on tenant move-in, lease completion or insurance renewal.
Confirm who needs the renewed certificate
Renewed commercial gas paperwork is often needed by more than one person. A restaurant manager may need it for insurance, a commercial landlord may need it for a lease file, a managing agent may need it for a tenant handover and a facilities team may need it for their compliance records.
Send the right contact details before the visit if the paperwork needs to go to a business owner, landlord, tenant, property manager, insurer, contractor portal, facilities team or accounts contact. This avoids delays after the appointment.
Check the right competence for the renewal
Commercial gas renewal should be matched to the correct equipment, fuel type and commercial setting. Gas Safe Register is the official list for gas businesses and engineers, and HSE guidance explains why employers and catering operators must treat gas appliances, maintenance and ventilation seriously.
Before booking, check that the renewal route matches the site: catering appliances, non-domestic installations, LPG, boilers and plant rooms are not all the same.
Send the renewal details once
Use the form to send the postcode, old certificate date, certificate requested, business setting, fuel type, appliance changes, access notes and renewal deadline. We will confirm the next suitable route by phone or email.
Commercial gas certificate renewal FAQs
How early should I start a commercial gas certificate renewal?
Start around 30 days before expiry where possible. If the certificate is needed for insurance, trading, lease completion, tenant handover or a managing-agent deadline, send the details earlier and call if the date is close.
Can a commercial gas certificate be renewed before it expires?
Yes. Renewing before expiry gives more time to arrange access, check the correct certificate route and deal with any follow-up actions if issues are found.
What if the old commercial gas certificate is missing?
You can still send an enquiry. Provide the site address, business type, appliance list, fuel type, certificate wording requested and any known expiry or deadline.
Is a commercial gas certificate renewal the same as a boiler service?
No. A boiler service and a commercial gas certificate or record are not automatically the same thing. If you need both, say so in the enquiry and list the boiler, plant or appliance details.
Do I need to send the old certificate before renewing?
It is helpful but not always essential. The old certificate can show the previous route, issue date, appliance list and notes. If you cannot find it, send the site address, equipment list, fuel type, requester wording and deadline instead.
Should I mention changes since the last commercial gas certificate?
Yes. New appliances, removed appliances, changed tenants, different opening hours, LPG changes, kitchen alterations, boiler work or new landlord wording can all affect the renewal route and appointment planning.
Does renewal always mean the same certificate as last year?
No. The correct record can change if appliances, fuel type, site use, tenant responsibility, insurer wording or landlord requirements have changed since the previous visit.
Can portfolio renewals be grouped?
Yes. Send a structured list of sites, old certificate dates, appliance notes, access contacts and deadlines. This helps plan renewals for landlords, agents, facilities teams and property managers.
Who should receive the renewed commercial gas paperwork?
Confirm whether the paperwork should go to the business owner, landlord, tenant, managing agent, insurer, facilities team, accounts contact or contractor portal. Include any site reference or trading name that must appear on the record.
Do restaurants and takeaways need to renew before insurance renewal?
If an insurer has asked for current commercial gas paperwork, send their wording and deadline early. Restaurants and takeaways may need catering gas details checked, especially where the request mentions CP42 or commercial kitchen equipment.
What should I do if the certificate has already expired?
State the expiry date, site status, business use and deadline clearly. Call if the renewal is linked to trading, insurance, local authority contact, lease completion or a tenant handover.
Can renewal be combined with other compliance certificates?
Yes. If the same site also needs electrical, EPC, fire alarm, emergency lighting or fire risk assessment paperwork, include those requirements at the start of the enquiry.
