Who Is Responsible for Gas Certificates in Commercial Properties?

Commercial landlord, tenant and operator guide

Responsibility follows ownership, provision, control and use—not one job title

A landlord can retain plant and common services, a tenant can operate workplace equipment, an employer controls day-to-day use, and an agent can arrange the work. Mixed-use, catering and LPG premises add further boundaries. Map every asset before requesting a record.

Asset ownership mappedWorkplace control checkedRecord matched to duty

The direct answer

Ask four questions for every appliance and pipework section

Ownership and provision

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.

Control

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.

Premises use

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.

Written allocation

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.

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

Commercial landlord

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.

Business tenant

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.

Employer or operator

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.

Managing agent or facilities team

Coordination and evidence

Maintain the asset list, arrange the correct engineer, coordinate permits and occupiers, retain records and escalate defects. The management agreement should define these tasks.

Engineer or contractor

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.

LPG supplier or tank owner

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

Contract wording and actual control must agree

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. Walk the site, reconcile the asset register and obtain advice where the legal allocation is uncertain.

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 or CP42-style record	Employer, kitchen operator, tenant or landlord according to equipment ownership and control.	Every catering appliance plus the agreed pipework, ventilation, extraction and interlock scope.	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

Relevant landlord fittings

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.

Workplace-only equipment

Appropriate safe-maintenance plan

Set the maintenance and inspection arrangement from the legal duty, manufacturer instructions, equipment, use, condition, risk and applicable standards.

Commercial catering

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.

LPG supply equipment

Component and ownership route

Tank, regulators, valves, service pipework and appliances can have different owners, maintenance needs and competent-person recommendations.

What Upkeepone can check from the brief

The supplied information can be used to identify the likely natural-gas, commercial boiler, catering, LPG, landlord, mobile-catering or specialist route, the engineer categories and whether the enquiry is within an available service area. Legal responsibility or a satisfactory inspection result cannot be determined from a document name alone.

Possible gas escape

Control the immediate risk before debating responsibility

HSE says that if a leak is suspected, turn off the supply if safe and immediately call 0800 111 999 for natural gas or the LPG supplier for liquefied petroleum gas. Do not turn the supply back on until the leak has been dealt with by a competent person. Evacuate and call 999 where there is fire, immediate danger or doubt.

Commercial gas responsibility questions

Commercial gas responsibility FAQs

Who is responsible for gas safety in a commercial property?

Responsibility depends on the premises use, who owns and provides each appliance, who controls the workplace and installation, the lease and any specific landlord, employer, operator or LPG duties. A landlord, tenant, employer, managing agent and contractor can each have different tasks. Map the responsibility asset by asset rather than naming one party for the whole building.

Does every commercial landlord need an annual gas safety certificate?

No single rule requires the same annual certificate for every purely non-residential commercial tenancy. Annual landlord gas-safety checks apply where the landlord duties cover relevant rented residential or guest accommodation and the gas fittings are within that regime. Retained commercial plant and common systems can still require safe maintenance, inspection and suitable records.

What gas responsibilities does a commercial tenant have?

GOV.UK says a business tenant will normally be responsible for workplace risk assessment and gas-safety arrangements, including maintaining equipment according to manufacturer instructions, subject to the lease and applicable law. The tenant should identify its own appliances, alterations and areas under its control and cooperate with the landlord over retained or shared systems.

Can a commercial lease transfer all gas-safety responsibility?

A lease can allocate repairs, maintenance, access, costs and practical tasks, but it should not be treated as removing statutory duties from a landlord, employer, tenant or person in control where those duties apply. Review the lease, ownership and actual control together, and obtain legal advice where the allocation is disputed.

Is a managing agent responsible for arranging gas checks?

An agent can be contracted to maintain the asset list, instruct competent engineers, arrange access, keep records and distribute documents. The management agreement should state those tasks clearly. Depending on the premises and legal regime, the landlord, tenant or employer can retain duties even where an agent manages the appointment.

Who pays for a commercial gas inspection—the landlord or tenant?

Payment normally depends on the lease, service-charge provisions, maintenance contract, appliance ownership and the work requested. The party paying is not automatically the only legal dutyholder. Confirm the scope, authorising party, invoice recipient and responsibility for defects or follow-up before booking.

Who is responsible where a shop has a flat above?

HSE says domestic landlord duties apply to the flat. Identify every appliance and flue serving the flat, including equipment located elsewhere in the building. Workplace-only gas equipment in the shop can follow a separate maintenance and inspection route, so the scopes should be mapped rather than combined under one generic certificate.

Who should arrange a commercial catering gas inspection?

The employer or business operator must ensure relevant catering gas appliances, flues, pipework and safety devices are maintained safely. The lease should also identify landlord-retained supplies, plant or ventilation responsibilities. The booking should cover every appliance, extraction, make-up air, interlock and connection within the agreed scope.

Who is responsible for LPG tanks and service pipework?

Responsibility can be divided between the LPG supplier, tank owner, premises owner, landlord, tenant and site operator. HSE says service pipework is often owned by the premises owner rather than the supplier, but the supply contract must be checked. Record the tank or cylinders, valves, regulators, pipework route and ownership before arranging work.

What should I send Upkeepone before booking?

Send the postcode, every premises use, lease or responsibility summary, landlord and tenant details, natural gas or LPG supply, ownership of each appliance and pipework section, complete appliance list and data plates, areas served, ventilation or extraction, previous records, known faults, access, target date and the exact record requested.
