Gas responsibilities in rented and shared business premises
Establish responsibility for each appliance and shared system
Commercial gas responsibilities can be shared between a landlord, business tenant, employer and managing agent. Start with the use of the premises, who owns and provides the equipment, and who controls its operation and maintenance. Read the lease and management agreements alongside those facts.
The person booking an inspection or receiving its invoice may be different from the person holding the legal duty. Use the matrix below to identify the equipment, the responsible parties and the evidence each needs.
The direct answer
Ask four questions for every appliance and pipework section
The HSE legal guidance used here concerns Great Britain. For Northern Ireland premises, check the applicable duties separately. The examples below help organise an enquiry; support for the actual installation must be confirmed.
Who owns and supplies it?
Record who owns each boiler, heater, catering appliance, tank, regulator, flue and pipework section and who provided it for workers, tenants, residents or guests.
Who operates the premises and equipment?
Identify the employer, tenant, business operator or person controlling access, use, shutdown, maintenance and day-to-day safety arrangements.
Workplace, accommodation or both?
Separate offices, shops, kitchens, factories, guest rooms, flats, staff accommodation, common areas, plant rooms and mobile units. Different duties can apply within one building.
What do the lease and contracts say?
Check repair clauses, service charges, retained systems, tenant alterations, agent instructions and maintenance contracts against who actually controls each asset.
Legal duty, practical task and payment are not the same question
One party may hold a statutory duty, another may arrange the appointment and a third may pay under the lease. Record all three rather than assuming the invoice recipient is the only responsible person.
Keep unresolved work visible during a handover
When a tenancy, agent or maintenance contract changes, hand over the asset list together with outstanding defects, access restrictions and work already instructed. Name the contact taking each action forward and ask them to acknowledge receipt. A folder of certificates alone may not show what remains unfinished.
For shared plant, agree how findings will reach each affected occupier and who can authorise the next visit. Record uncertainty about ownership or payment for the property adviser to resolve; do not mark a safety action complete simply because the parties are discussing responsibility.
Important: this is practical general guidance, not legal advice about a particular lease, incident or dispute.
Responsibility matrix
Start with the area, asset and person in control
| Situation | Likely starting responsibility | Evidence to check | Do not assume |
|---|---|---|---|
| Owner-occupied office, shop or workplace | The employer or self-employed person controlling the workplace must arrange safe maintenance of relevant gas appliances, pipework and flues. | Asset schedule, manufacturer information, maintenance plan, inspection, service and repair records. | That every owner-occupied workplace needs the same annual certificate. |
| Landlord-retained plant or common gas system | The lease and actual control should identify the landlord, freeholder or agent arranging maintenance and access. | Lease, service-charge provisions, plant ownership, areas served, maintenance contract and records supplied to occupiers. | That the tenant controls equipment merely because it serves the tenant’s unit. |
| Tenant-installed or tenant-controlled equipment | The business tenant or employer will commonly arrange safe operation, maintenance and suitable gas work, subject to the lease and law. | Alteration consent, installation and commissioning records, appliance ownership, maintenance history and workplace risk arrangements. | That ownership removes every landlord or building-control interest in shared supplies and fabric. |
| Relevant rented residential or guest accommodation | The landlord duties can require annual checks and records for appliances and flues owned and provided for occupants. | Tenancy or licence, areas served, appliance provision, check dates, records and distribution to relevant occupants. | That calling the building commercial removes residential landlord duties. |
| Shop or workplace with a flat or staff accommodation | Separate the landlord route for relevant accommodation from workplace-only equipment and coordinate shared systems. | Asset-to-area map, boilers serving several areas, flues, common pipework, access and distinct records. | That one CP12- or commercial-labelled document automatically covers every area. |
| Restaurant, takeaway or fixed commercial kitchen | The employer or operator must keep relevant catering appliances, flues, pipework and safety devices safe; the landlord may retain supplies or plant. | Lease boundary, appliances, extraction, make-up air, interlocks, flexible connections, operating hours and inspection records. | That a landlord or boiler record covers the cooking line. |
| Bulk-LPG or cylinder-fed commercial site | Responsibility can be split between supplier, tank owner, premises owner, landlord, tenant and operator. | Supply contract, tank or cylinders, valves, regulators, service-pipework ownership and route, appliances and maintenance records. | That the LPG supplier owns or maintains every pipe after the tank. |
| Factory, agriculture or specialist process | The employer or site operator must use the applicable competent-person and plant-safety route. | Process risk, fuel, equipment, pressure, competence evidence, site standards and maintenance or inspection scheme. | That an ordinary commercial certificate answers every industrial responsibility. |
People and organisations
Several parties can hold different parts of the work
Retained assets and relevant accommodation
Identify central plant, common supplies, landlord appliances, flues, meters, risers and systems serving flats, guests or staff accommodation. Record what the lease retains.
Workplace and tenant equipment
GOV.UK says business tenants will normally have workplace health-and-safety responsibilities, including gas-equipment maintenance, while much of the repair allocation depends on the lease.
Safe day-to-day use
Control appliance operation, trained users, ventilation, shutdown, known defects, maintenance instructions and access for competent work. Do not use equipment known or suspected to be unsafe.
Coordination and evidence
Maintain the asset list, arrange the correct engineer, coordinate permits and occupiers, retain records and escalate defects. For relevant landlord checks, HSE explains that an agent contractually assigned the maintenance and safety-check duties can have the same duties as the landlord. The landlord should obtain evidence that the work has been completed.
Defined competent work
The contractor must be competent for the fuel, appliance, premises and work. Their appointment does not replace the dutyholder’s need to define the scope and act on findings.
Supply boundary and emergency route
Confirm tank, valves, regulators, service pipework and emergency responsibilities in the supply contract. Do not infer ownership from who originally installed the pipe.
Read the lease—but also inspect reality
Read the lease alongside the installation and its use
A commercial lease may allocate repairs, maintenance, service charges, tenant alterations, access and common services. GOV.UK notes that business-property responsibilities are partly legal and partly dependent on the lease.
A lease does not by itself identify an undocumented appliance, a shared boiler, an LPG pipe route or which system serves guest accommodation. Reconcile the asset register with the premises and obtain advice where the legal allocation is uncertain. A full repairing and insuring lease should not be treated as transferring the relevant residential landlord gas duties to the tenant. HSE distinguishes these duties from those applying to exclusively non-residential equipment.
Responsibility before record name
A “commercial gas certificate” is not one universal legal document
| Work or record | Who commonly arranges it? | What it should identify | Important boundary |
|---|---|---|---|
| Planned service or maintenance | Party controlling or contractually maintaining the equipment. | Appliance, tasks, condition, settings, findings, parts and next action. | A service is not automatically a safety certificate. |
| Workplace safety inspection | Employer, operator, tenant, landlord or facilities team responsible for the defined system. | Assets, accessible checks, tests, limitations, defects and engineer competence. | There is no single annual record for every purely commercial workplace. |
| Landlord Gas Safety Record | Landlord or contracted agent where the relevant residential or guest duties apply. | Covered appliances and flues, checks, results, engineer, date and recipient requirements. | It does not automatically cover workplace-only plant or catering equipment. |
| Commercial catering inspection record, such as CP42 | Employer, kitchen operator, tenant or landlord according to equipment ownership and control. | Appliances checked, relevant gas-safety checks of the catering environment and controls, findings, limitations and any incomplete work. | CP42 is not a universal certificate for all commercial gas systems. |
| LPG inspection record | Owner or operator responsible for the defined tank, cylinder, pipework or appliance scope. | Fuel, supply components, pipework, appliances, findings, limits and ownership boundary. | An appliance record does not prove the complete LPG supply was inspected. |
| Repair or commissioning report | Party authorising the installation, alteration or remedial work. | Work completed, tests, parts, settings, safety actions and outstanding items. | It should not be represented as an unrelated annual certificate. |
Inspection frequency
Do not assign “every 12 months” to every commercial asset
Annual check where Regulation 36 applies
Covered landlord appliances and flues serving relevant rented residential or guest accommodation follow the annual-check and record regime.
Appropriate safe-maintenance plan
Set the maintenance and inspection arrangement from the legal duty, manufacturer instructions, equipment, use, condition, risk and applicable standards.
Equipment- and use-based interval
HSE says intervals may vary and should follow manufacturer recommendations and industry practice; annual inspection is a reasonable general minimum.
Component and ownership route
Tank, regulators, valves, service pipework and appliances can have different owners, maintenance needs and competent-person recommendations.
Request a scoped quotation
Send the responsibility and asset brief together
Landlord, tenant, employer and agent
Name the property owner, occupiers, business operator, person authorising work, managing agent and the recipient of the record.
Every use and occupied area
List shops, offices, kitchens, hotels, guest rooms, flats, staff accommodation, factories, plant rooms, common areas and mobile units.
Natural gas, LPG or both
Identify meters, tank or cylinders, regulators, known isolation, pressure where available, pipework route and who owns each section.
Ownership and areas served
Send makes, models, data plates and locations for every boiler, heater, cooker, water heater or plant item, including who provided it and what it serves.
Lease, records and recipient request
Attach the relevant lease summary, asset schedule, previous certificates, service reports, unsafe notices, alterations and exact document request.
Access, shutdowns and target date
Describe keys, permits, roof or plant access, parking, escorts, trading constraints, known faults and the required appointment window.
What Upkeepone can check from the brief
Upkeepone can assess the declared fuel, equipment, proposed work and postcode before confirming whether it can support the inspection, the suitable engineer availability and quotation terms. A brief summary of the relevant responsibilities is useful for an initial enquiry; a disputed lease allocation needs appropriate legal advice. A satisfactory inspection result depends on the findings.
Before booking, agree access and any interruption of gas use, who receives the report, and who can authorise action on defects or incomplete checks. Servicing, repairs, parts, commissioning, testing or purging beyond the agreed inspection, and extraction maintenance or specialist assessment need their own terms. Necessary gas-safety checks remain part of completing the agreed work safely.
Possible gas escape
Control the immediate risk before debating responsibility
A suspected gas leak needs emergency action while ownership or payment is being resolved. Contact the emergency service from a safe place: 0800 111 999 for natural gas in Great Britain, or the LPG supplier for LPG. Avoid ignition sources; only isolate the supply if safe. Evacuate if there is doubt about safety and call 999 for fire or immediate danger. The supply must remain off until a competent person has dealt with the leak.
Service areas
Service areas for inspection enquiries
For LPG enquiries and commercial natural-gas inspections, London, Essex and Kent are our priority areas. Hertfordshire, Surrey, Buckinghamshire, Berkshire and Sussex are also covered. Other UK locations are considered by request.
Attendance is subject to the full postcode, installation, access, travel and availability of an appropriately qualified engineer. For shared premises, identify the systems involved and coordinate access with the affected occupiers before an appointment is agreed.
Acceptance of each installation must be checked. Servicing, repairs, installations and specialist work need their scope, coverage and engineer availability confirmed separately.
