Step-by-step

How to obtain a commercial gas safety certificate

Use these steps if you need paperwork for a shop, restaurant, office, warehouse, managed unit, commercial landlord property, hospitality site or other non-domestic premises.

1. Confirm why the certificate is needed

State whether it is for annual renewal, insurance, lease completion, tenant handover, sale, opening date, landlord file, managing agent request or urgent compliance query.

2. List the gas equipment

Include boilers, water heaters, catering equipment, warm-air heaters, unit heaters, LPG appliances, commercial kitchen equipment, plant rooms and landlord-controlled systems.

3. Check the likely route

A catering kitchen, non-domestic boiler, LPG setup, landlord-controlled system or industrial unit may each need a different commercial gas record or certificate route.

4. Send access details

Give the site contact, opening hours, key-holder, plant-room location, parking, loading, reception process, alarm details, tenant contact and any restricted access rules.

5. Confirm engineer suitability

Commercial gas work should be carried out by a Gas Safe registered engineer with the correct commercial category for the appliance, fuel and setting.

6. Keep the paperwork with the property file

After the visit, keep the certificate, report or remedial notes with your lease, insurance, landlord, managing agent or compliance records.

Before booking

Information to send before you request a commercial gas certificate

You do not need to know every technical term before contacting an engineer, but the following details help the booking start in the right place.

  • Full property address, postcode, unit number, business name and site contact.
  • Property type: restaurant, cafe, takeaway, shop, office, warehouse, school, care home, hotel, pub, managed unit, landlord property or mixed-use premises.
  • Gas appliances and systems: catering equipment, boilers, plant, water heaters, warm-air heaters, unit heaters, LPG equipment, cylinders, tanks or shared building services.
  • Fuel type: natural gas, LPG cylinders, LPG tank, mobile LPG, landlord supply or unknown.
  • Exact wording requested by the insurer, landlord, managing agent, buyer, lease, tenant, council, facilities team or compliance file.
  • Access notes: opening hours, preferred appointment window, key-holder, duty manager, reception, parking, loading, plant-room location, alarm and tenant restrictions.
  • Deadline and reason for the paperwork, especially where lease completion, insurance renewal or opening date is close.
Competence check

Who can issue commercial gas paperwork?

Commercial gas work should be handled by a Gas Safe registered engineer with the correct category for the type of gas work being carried out. A domestic-only registration does not automatically cover commercial catering equipment, commercial boilers, LPG systems, plant rooms or other non-domestic gas work.

Before an appointment is confirmed, the appliance type and site use should be clear enough to check the likely competence route. That is why the first enquiry should include the equipment list, fuel type and certificate wording rather than only asking for a generic commercial gas certificate.

Important

If you are acting for a landlord, tenant, agent or facilities team, send the wording from the person requesting the certificate. It helps avoid booking a domestic landlord certificate when the property needs non-domestic commercial gas paperwork.

Send wording for checking
Inspection day

What happens after the appointment is arranged?

The engineer will need suitable access to the relevant appliances, isolation points, flues, plant rooms, kitchen areas, boiler rooms, landlord-controlled spaces or LPG storage areas. The exact checks depend on the equipment and certificate route.

If defects, unsafe conditions, blocked access or missing appliance information are found, the next step may involve remedial advice, additional details, access rearrangement or a follow-up route before final paperwork can be completed. Keep any notes with the property file so the responsible person can act quickly.

After enquiry

What happens after you send the certificate request?

The enquiry is checked against the property type, appliance list, fuel type, certificate wording, access notes and deadline. This helps identify whether the request is likely to involve CP42, CP17, CP15, CP16, LPG, commercial boiler or plant paperwork, or another commercial gas route.

If the request is urgent, explain why the paperwork is needed: insurance renewal, lease completion, tenant handover, buyer request, opening date, managing agent file or annual compliance record. The next suitable appointment route can then be confirmed by phone or email.

Avoid the wrong certificate route

Do not rely on the certificate name alone. Send the appliance list and the exact wording requested so the enquiry can be checked before a visit is agreed.

Official checks

Official sources to check before you obtain paperwork

Use official sources to understand engineer registration, commercial categories and workplace gas duties. They help confirm why the appliance type, fuel type and setting must be clear before a commercial gas appointment is booked.
