Commercial LPG safety guide

Commercial LPG Gas Certificate London

Arrange commercial LPG gas safety paperwork for a London business, managed property, hospitality venue or mobile unit. This guide explains how cylinders and bulk tanks change the enquiry, what an appliance visit may cover, who controls different parts of the installation and what to send for a useful quotation.

For a useful quotation

Describe the LPG installation, not only the certificate name

A cylinder-fed catering trailer, a restaurant supplied from a bulk tank and a managed building with LPG heating are different jobs. Clear information helps match the enquiry to the right commercial LPG competence and avoids an unsuitable appointment.

  • Full London address or mobile-unit location and postcode.
  • Cylinders or bulk tank, propane or butane if known.
  • Complete appliance list and photographs of data plates.
  • Reason, requester wording, access restrictions and deadline.

Four common commercial LPG arrangements

The fuel source affects the engineer category, inspection scope and site information needed. Identify the closest arrangement below and disclose any second supply or appliance group.

Cylinder-fed fixed premises

Restaurants, pubs, workshops and rural or temporary commercial buildings may use replaceable cylinder banks. State where full and empty cylinders are kept, what they supply, how the changeover is arranged and who controls the store.

Bulk LPG tank sites

A tank may supply catering, heating, hot water or several buildings. Give the supplier, tank location, service-pipe route if known, site access, emergency number and whether the tank is owned, hired or leased.

Mobile catering and events

Vans, trailers, stalls and event kitchens need the unit type, LPG storage, appliances, hoses and regulators, pitch rules, event date and setup window. A mobile certificate request should not be treated as a fixed restaurant inspection.

Mixed-fuel or multi-use sites

Some premises use LPG outdoors and mains gas indoors, or have separate catering and heating systems. List each fuel and appliance group so commercial catering, boiler, pipework and LPG work can be scoped separately where necessary.

Agree the scope first

What a commercial LPG safety visit may cover

The quotation should name the appliances, installation section and record expected. Depending on the agreed work and the engineer's categories, a visit may consider accessible LPG appliances, isolation and emergency controls, visible pipework and connections, safety devices, combustion, flueing and ventilation, signs of deterioration and whether the equipment appears suitable for the stated gas.

The resulting record should identify the inspected scope, findings, defects, limitations and any action advised. It should not imply that an unseen or excluded tank, cylinder compound, buried pipe, pressure system or appliance has been certified.

Ask for these points in writing

  • Named appliances and supply arrangement.
  • Safety inspection, service, repair or commissioning.
  • Tank, cylinders, pipework and regulator boundaries.
  • Record or certificate wording to be issued.
  • Exclusions, access assumptions and remedial-work process.
Responsibility follows control

Supplier, site user, landlord and tenant roles can overlap

HSE says businesses operating LPG installations have duties to keep them safe and manage risks. A supplier may own and maintain a bulk tank, but the site user still controls everyday conditions and work around it. Record the division of responsibility instead of assuming the supplier or landlord covers everything.

Site operator or employer

Manage workplace risks, emergency arrangements, access, security and activities around the installation. Keep records of the supply route, assessments, maintenance, inspections and reported defects.

LPG supplier or tank owner

Often maintains the supplier-owned tank and fittings and provides delivery and emergency arrangements. Check the written agreement because ownership and responsibilities vary.

Landlord, tenant or facilities team

Define who controls appliances, plant, service yards, cylinder cages, building pipework and access. Share lease wording, supplier contracts and previous records before booking.

Competent gas business

Work only within the registered engineer's current LPG, commercial and appliance categories, explain the inspected boundary and record unsafe findings or limitations clearly.

Bulk LPG sites

The tank area and service pipework need their own attention

HSE identifies tank siting, ventilation, separation from buildings, boundaries and ignition sources, tanker access, security, impact protection and emergency planning as matters the user should manage with the supplier. Changes made after installation, such as fences, sheds, electrical equipment, parking or vegetation, can affect the original safety arrangement.

LPG vapour is heavier than air. Nearby drains, gullies, basements and other low points matter because escaped vapour may collect rather than disperse. Buried metallic service pipework also needs particular attention because corrosion can allow LPG to migrate towards buildings.

Photographs that help

  • Tank, valve cover and supplier identification.
  • Tank surroundings, barriers, access and nearby drains.
  • Visible service-pipe route and building entry point.
  • Regulators, emergency control valve and warning signs.
  • Appliance data plates and previous record pages.
Separate specialist work

A certificate visit does not cover every LPG duty

Several related requirements can exist at the same site. They should be named separately so the customer receives the right competence, time and evidence.

Tank integrity and supplier work

Tank maintenance, filling arrangements, supplier-owned fittings and emergency response normally require the supplier's involvement. Do not assume an appliance record signs off the tank.

Pressure-system examination

Certain LPG pressure systems can require a written scheme and periodic examination by a competent person under pressure-systems legislation. This is different from a routine appliance safety record.

DSEAR and fire-risk controls

Workplace fire and explosion risk assessment, hazardous-area classification, cylinder-store design and emergency planning are wider management duties and may need separate competent advice.

Repairs, conversion and commissioning

Replacing pipework, changing regulators, converting an appliance between gases, pressure testing, purging, commissioning and remedial parts are separate unless expressly quoted.

Before booking

Commercial LPG quotation checklist

Send one complete enquiry so the fuel, appliance and site-control questions can be reviewed together.

  • Contact name, telephone, email, business name, full address and postcode.
  • Premises type and whether the LPG system is fixed, mobile, temporary or event-based.
  • Propane or butane if known; cylinder sizes and quantity, or bulk-tank details and supplier.
  • Every gas appliance, make and model where known, purpose and approximate input rating.
  • Photographs of appliance data plates, cylinders or tank, regulators, valves and visible pipework.
  • Previous certificates, service records, supplier paperwork, risk-assessment notes and known defects.
  • Exact wording requested by the insurer, venue, council, landlord, tenant or facilities manager.
  • Access contact, gates, cages, loading or parking restrictions, trading hours and shutdown limits.
  • Reason and deadline, including opening, event, pitch approval, insurance, lease or annual review.
After the visit

Read the scope and findings before filing the record

Check the business and site details, fuel, appliance schedule, inspected installation boundary, findings, defect classification, limitations and engineer information. Send the correct record to the person who requested it, but keep a copy with supplier, maintenance and access records so future decisions are based on the same installation information.

If defects or excluded work are recorded, ask for a separate remedial quotation or the appropriate supplier or specialist route. A record that identifies a problem is not evidence that the repair has already been completed.

Before accepting the paperwork

  • Is every expected appliance listed?
  • Does it identify LPG and the installation boundary?
  • Are defects, limitations and excluded items clear?
  • Does the engineer's category match the work?
  • Who will arrange supplier or remedial follow-up?
Smell LPG or suspect an escape?

Do not wait for a certificate appointment. Keep people away, avoid flames and anything that could create a spark, follow the site and supplier emergency procedure, and use the emergency number displayed on the tank or supplier paperwork. Evacuate and call 999 if there is fire or immediate danger. Only operate isolation valves when the procedure says to do so and it is safe.

    Common customer questions

    Commercial LPG gas certificate FAQs

    What is a commercial LPG gas certificate?

    Commercial LPG gas certificate is a customer term for suitable gas safety paperwork relating to an agreed LPG installation or appliance scope. It is not one universal certificate covering every cylinder, tank, pipe, regulator and appliance. The record should identify what was inspected, the findings, any limitations and the engineer or business responsible for the gas work.

    Which London businesses may need commercial LPG gas paperwork?

    Restaurants, pubs, hotels, commercial kitchens, event caterers, market traders, workshops, offices, schools, care settings and managed premises may use LPG for cooking, heating, hot water or specialist equipment. The correct enquiry route depends on whether the setup is fixed, mobile or temporary, uses cylinders or a bulk tank, and whether the equipment is commercial catering, heating or another category.

    Does an LPG appliance check include the cylinders or bulk storage tank?

    Not automatically. An appliance visit may consider the agreed supply arrangement and accessible controls needed for safe operation, but cylinder storage, a supplier-owned tank, separation distances, filling access, pressure-system examinations or the integrity of the entire installation may sit with the LPG supplier or require a separate specialist scope. Confirm this before booking.

    Who is responsible for safety at a commercial bulk LPG site?

    Responsibility is often shared. The supplier commonly owns and maintains the tank and fittings, subject to the agreement, while the business operating the site still controls matters such as the area around the tank, access, security, impact protection, emergency arrangements and activities that could affect it. Landlords, tenants and facilities teams should record who controls each part rather than relying on assumptions.

    How often should commercial LPG appliances be checked?

    Use the manufacturer instructions, risk assessment, operating conditions and competent advice to set the interval. Gas Safe advises annual safety checks and servicing for fixed LPG appliances or following the manufacturer guidance. Other parts of a commercial installation, including a pressure system or supplier-owned tank, may follow different inspection or examination arrangements.

    Can the same engineer work on every commercial LPG system?

    No. Gas Safe registration alone does not mean an engineer is qualified for every fuel, appliance, pressure or premises category. Check the engineer or registered business for LPG and the relevant commercial appliance or work category. Catering equipment, boilers, mobile units, vessels and commercial pipework can require different competence.

    What information should I send for an LPG quotation?

    Send the full address and postcode, business type, reason and deadline, propane or butane if known, cylinder or bulk-tank arrangement, fixed or mobile status, appliance list and photographs of data plates, regulator and pipework details if available, tank or cylinder location, supplier information, previous records, known faults and site access restrictions.

    Is an LPG safety inspection the same as servicing or repair?

    No. A safety inspection records the condition and findings for an agreed scope. Cleaning, servicing, replacement parts, fault diagnosis, alterations, conversion between gases, pipework replacement, tank work, pressure testing, purging and commissioning are separate unless the quotation expressly includes them. Ask for the included work and exclusions in writing.

    Why do drains, basements and low areas matter around LPG?

    LPG vapour is heavier than air, so an escape can collect in drains, gullies, basements or other low points instead of dispersing. HSE guidance therefore treats tank siting, ventilation and nearby untrapped drains as important. Do not alter the area around a tank or cylinder store without checking how the change affects safety.

    What should I do if I smell LPG or suspect a leak?

    Treat it as an emergency, keep people away, avoid flames and anything that could create a spark, and follow the supplier emergency instructions. Bulk tanks should display the supplier emergency number. If there is fire or immediate danger, evacuate and call 999. Only close a valve when your emergency procedure says to do so and it is safe; do not restart the supply until competent advice confirms it is safe.

    Need commercial LPG gas paperwork in London?

    Send the cylinder or tank arrangement, appliance list, photographs, access notes and deadline. The enquiry can then be checked against the correct LPG and commercial work category.
