Prepare properly so your commercial gas inspection runs smoothly
A commercial gas inspection can be delayed by simple issues: no key holder, locked plant rooms, missing appliance details, unclear certificate wording or a kitchen that cannot be accessed during service. This guide helps landlords, tenants, agents, business owners and facilities teams prepare before the engineer attends.
Send practical site details before the visit is confirmed
The most useful enquiry is not just "I need a certificate". Send the site type, appliance list, fuel type, certificate wording, access contact and deadline so the appointment can be planned around the correct commercial gas route.
Before the inspection: what to arrange
A well-prepared commercial gas inspection starts before the engineer arrives. Use this checklist if you are booking for a restaurant, shop, office, pub, hotel, warehouse, school, care setting, landlord unit or managed commercial premises.
- Confirm the exact address, postcode, unit number, trading name and site contact.
- Confirm the property type and who controls the equipment: tenant, landlord, managing agent, facilities team, shared service or business owner.
- List the gas equipment, including commercial kitchen appliances, boilers, water heaters, warm-air heaters, unit heaters, LPG equipment, plant rooms and landlord-controlled systems.
- State the fuel type: natural gas, LPG cylinders, LPG tank, mobile LPG, landlord supply or unknown.
- Send the certificate wording requested by the insurer, landlord, managing agent, buyer, lease, compliance file or facilities team.
- Confirm the deadline and reason for the inspection: annual renewal, insurance, lease, tenant handover, opening date, sale, audit or urgent compliance request.
- Tell the engineer about opening hours, trading peaks, kitchen prep times, visitor procedures, parking, loading and building management rules.
Make the right areas available before the engineer arrives
Commercial sites often have separate people responsible for keys, kitchens, plant rooms, landlord areas and tenant units. Clarify access early to avoid wasted visits.
Key holder and site contact
Make sure the person meeting the engineer can access the correct areas and knows which equipment is included in the inspection request.
Plant rooms and boiler rooms
Check keys, alarms, access codes, roof spaces, risers, locked cupboards and building management rules before the appointment time.
Commercial kitchens
Plan around preparation, service, cleaning and delivery windows so catering appliances can be accessed safely and without unnecessary disruption.
Tenant and landlord areas
If equipment sits across tenant space and landlord-controlled areas, confirm who gives access to each part of the building.
LPG and external storage
Tell the engineer where cylinders, tanks or mobile LPG equipment are kept and whether any outdoor or event-related access rules apply.
Parking and loading
Explain parking, loading bays, permits, congestion restrictions, site security and reception procedures, especially in central London locations.
Have previous records and certificate wording ready
Previous certificates, appliance lists and service records can help clarify what has been inspected before, but they should not replace a current check. If a landlord, insurer, buyer or managing agent has asked for specific wording, send that wording before the visit is confirmed.
This is especially important where customers use broad phrases such as "commercial gas certificate". A restaurant kitchen, non-domestic boiler, commercial landlord unit, LPG setup or office plant room may need a different route.
Send the wording, not just the certificate name
If the request came from an insurance renewal, lease, tenant handover or sale, copy the exact line into the enquiry. It helps avoid arranging the wrong commercial gas paperwork.
Send certificate wordingWhat helps the appointment run efficiently?
Make sure the duty contact is expecting the engineer and can stay reachable. If the building has reception, security, tenants, kitchen managers or facilities staff, tell them what has been booked and which areas may need access.
If the engineer finds missing access, changed equipment, unavailable key holders, unsafe conditions or unclear paperwork, the outcome may need further advice, remedial work, additional details or another route before final records can be completed. Good preparation reduces those avoidable delays.
What happens after you send the inspection details?
The enquiry can be checked against the site type, appliances, fuel type, access arrangements and certificate wording. This helps confirm whether the request is likely to sit under CP42, CP17, CP15, CP16, LPG, commercial boiler work or another commercial gas route.
If the details are clear, the next suitable appointment route can be confirmed by phone or email. If the wording is too broad, the access is unclear or the appliance list suggests a specialist category, those points can be clarified before the engineer attends.
Best detail to send first
Send the site postcode, business type, gas equipment list, fuel type, access contact, preferred visit window and the exact certificate wording requested by your landlord, insurer, managing agent or compliance file.
Send inspection detailsOfficial sources worth checking before inspection day
Official sources help customers understand why engineer competence, commercial categories, appliance details and workplace gas responsibilities matter. Use them alongside the practical booking checklist above.

Questions before a commercial gas inspection
Good preparation helps the appointment run more smoothly and reduces avoidable delays with paperwork.
What preparation helps a commercial gas inspection run smoothly?
Make sure appliance areas are accessible, key holders are available, previous records are ready if relevant, and the engineer knows about access restrictions, trading hours and deadlines.
Should old records be available for the visit?
Yes, if you have them. Previous certificates, appliance lists, service records and landlord or insurer wording can help clarify what paperwork has been requested.
What commonly delays commercial gas paperwork?
Missing appliance details, unclear certificate wording, restricted access, unavailable key holders, unknown fuel type and urgent deadlines given too late can all delay confirmation.
What happens if the appliance list changes before the visit?
Tell the booking contact before the appointment where possible. A changed appliance list may affect the time needed, the engineer category required or the paperwork route.
Who should be available during the inspection?
A key holder or responsible site contact should be available, reachable by phone and able to show the engineer the relevant appliances, plant areas, kitchen spaces, landlord areas and access points.
What happens if a gas safety issue is found?
The engineer should explain the immediate concern and the likely next step. Depending on the issue, the outcome may involve advice, remedial work, restricted use, further inspection or updated paperwork once the matter is resolved.
Preparing for a commercial gas inspection?
Send the postcode, site use, appliances, fuel type, access contact, requested paperwork and deadline. Call if the inspection is needed urgently.
