Commercial gas safety in London
Commercial Gas Safety Certificate London
Tell us what the premises uses, which gas appliances are installed and why the record is needed. We will check whether the enquiry concerns catering equipment, a boiler or plant room, commercial pipework, LPG or more than one inspection route.
Choose the correct route
What do you actually need checked?
Customers often arrive with a short instruction such as “get a commercial gas certificate”. That phrase is useful, but it does not describe the full job. A restaurant may need catering appliances and their ventilation arrangements considered. An office may only have a heating boiler. A landlord may control the plant while the tenant owns the kitchen equipment. An LPG installation can introduce storage and supplier responsibilities that do not arise with mains gas.
Send the wording exactly as it appears in the lease, insurer email, facilities schedule or previous record. If no code is stated, describe the equipment rather than guessing. We will use those facts to identify the most suitable enquiry route.
- Full site address and postcode
- Business use and opening hours
- Mains gas, LPG or mixed fuel
- Boilers, heaters, catering appliances and plant
- Previous record or requested certificate wording
- Access contact and required completion date
Commercial record routes
Use the equipment and purpose to narrow the booking
Certificate labels can vary between contractors and requesting organisations. These routes help you describe the work; the final scope should be confirmed against the actual installation.
Responsibility and maintenance
The person arranging the visit may not be the only dutyholder
HSE guidance for employers says gas pipework, appliances and flues must be regularly maintained, rooms containing gas appliances need adequate ventilation, and unsafe equipment must not be used. For workplaces such as shops, restaurants, schools and hospitals, gas fitting work must be completed by a Gas Safe registered engineer who is qualified for that work.
A commercial certificate does not transfer responsibility from the people who control the workplace, equipment or property. Identify who owns each appliance, who controls maintenance, who can authorise repairs and who will receive the report. This is particularly important at lease commencement, tenant handover and in mixed-use buildings.
Business owner or employer
Confirm the equipment used by staff, operating patterns, known faults, shutdown arrangements and the person authorised to respond if the engineer identifies a safety concern.
Commercial landlord or agent
Check the lease, appliance ownership, landlord-controlled pipework or plant, common areas, previous maintenance records and the access arrangements agreed with the occupier.
Facilities or building manager
Coordinate inductions, permits, keys, plant access, contractor rules and any residential areas served by the same system. Mixed-use premises may involve additional landlord duties.
What the appointment may cover
Agree the inspection scope before the engineer arrives
The checks depend on the appliance category and requested record. A suitable visit may consider identification and condition of the appliances, accessible pipework, flues, ventilation, safe operation, combustion performance and relevant safety controls. Commercial catering work may also require consideration of extraction, make-up air and gas interlocks. Testing or purging of commercial pipework is a specialist task and should be requested explicitly.
The resulting record should identify the site, engineer, appliances or installation covered, work completed, observations and any safety classification or recommendation that applies. Read the scope and limitations before sending the document to another party. A record that omits a landlord-controlled boiler, tenant appliance or inaccessible plant room may not answer the original request.
Ask to include
- Every relevant appliance and its location
- Fuel type and commercial work category
- Accessible pipework, ventilation and flue arrangements
- Safety devices or interlocks relevant to the installation
- The report or certificate wording requested
Confirm separately
- Routine servicing and replacement parts
- Repairs or remedial work found during inspection
- Kitchen extraction cleaning or ventilation alterations
- LPG tank or supplier-owned equipment
- Specialist pressure-system or commissioning work
Inspection intervals
Do not treat every commercial gas record as automatically valid for 12 months
Commercial gas equipment must be kept safe, but the evidence and interval are not identical for every installation. Check the manufacturer’s instructions, previous report, risk assessment, maintenance plan, lease, insurer request and any rules that apply to the premises. A recommendation for annual attendance may be sensible without making every document a statutory annual certificate.
For hospitality and catering equipment, HSE says inspection periods can vary according to the equipment and its use, should follow the manufacturer’s recommendations and, as a general rule, annual inspections are a reasonable minimum. A heavily used kitchen, an appliance with a known issue or a previous engineer instruction may justify earlier action. A business should also arrange attention when equipment is changed, relocated, damaged or suspected to be unsafe rather than waiting for a diary date.
Price and timing
Why a useful quotation needs more than the postcode
The cost is affected by what must be inspected and how the site can be accessed. One accessible boiler during normal working hours is a different job from a basement kitchen with several appliances, a roof-level flue, a locked plant room and an overnight attendance window. Fuel type, appliance quantity, commercial category, parking, induction and the need to coordinate several occupiers can all change the quotation or appointment length.
A low headline price is not helpful if it covers the wrong record or excludes equipment named in the request. Compare quotations against the same appliance list and scope. Ask whether attendance, inspection, record issue and any return visit are included. Repairs, replacement parts and remedial work should be separated unless the quotation expressly includes them.
For an insurer, lease, opening or handover deadline, send the date at the beginning of the enquiry. Do not assume that a same-day visit means the final document can be released immediately: access limitations, unsafe findings, missing information or specialist follow-up can affect completion. Booking early leaves time to resolve those issues without presenting an incomplete record to the requesting organisation.
After the visit
Read the record before filing or forwarding it
Check that the address, business name, fuel, appliance details and inspection scope are correct. Note any item recorded as inaccessible, not tested or outside the agreed work. If the engineer identifies a defect or gives an instruction about continued use, make sure it reaches the person who can control the equipment and arrange the required action.
Keep the record with previous certificates, service reports, repair invoices, appliance manuals and any ventilation or interlock information. That history helps the next engineer understand changes and gives landlords, tenants and facilities teams a clearer account of how the installation has been managed. Record the next review point from the applicable guidance, maintenance plan or engineer recommendation rather than relying only on a filename marked “annual”.
Prepare for the visit
Avoid a failed or incomplete appointment
Do not conceal a known fault or continue using an appliance that is suspected to be unsafe. Tell the engineer about smells of gas, unexplained shutdowns, damaged controls, poor combustion, ventilation changes or previous warning labels before the visit.
Suspected gas leak
This enquiry form is not an emergency service
If you suspect a natural-gas leak, turn off the supply where it is safe to do so and call the National Gas Emergency Service immediately on 0800 111 999. For LPG, contact the LPG supplier. HSE advises evacuation when in doubt and says the supply must not be turned back on until the leak has been dealt with by a competent person.

Common questions
Commercial gas safety certificate FAQs
What is a commercial gas safety certificate?
It is a commonly used description for the inspection record produced after agreed commercial gas safety work. There is no single record that suits every business. The correct scope depends on the premises, fuel, appliances, pipework and the wording requested by a landlord, insurer, managing agent or other responsible party.
Does every business need the same commercial gas certificate?
No. A restaurant kitchen, office boiler room, warehouse heater and LPG catering unit involve different equipment and competencies. Employers and people controlling workplaces must manage gas risks and keep relevant systems safe, but the inspection and record should be matched to the actual installation rather than selected from the business name alone.
How often should commercial gas equipment be inspected?
There is no universal expiry period for every commercial gas record. The interval can depend on legislation, the appliance manufacturer, equipment use, a previous engineer recommendation, risk assessment, lease or insurance terms. HSE says annual inspection is a reasonable minimum general rule for hospitality and catering equipment, while recognising that intervals may vary.
Who can carry out commercial gas work?
For workplaces such as shops, restaurants, schools and hospitals, HSE says gas fitting work must be carried out by a Gas Safe registered engineer who is qualified for that work. Check both the registration and the categories shown on the engineer's Gas Safe ID card, because domestic registration alone does not confirm competence for every commercial appliance or fuel.
What information should I send before booking?
Send the full postcode, business use, exact certificate or report wording, fuel type, appliance list, any plant or catering equipment, site contact, access restrictions and deadline. Attach the previous record or the request from your landlord, insurer or managing agent when available. Photographs of appliance data plates can also help identify the right route.
Is a commercial gas safety inspection the same as a boiler service?
Not necessarily. A safety inspection and a service have different purposes, although some checks may overlap. Servicing, repairs, replacement parts, catering ventilation work, LPG tank work and specialist testing should be confirmed separately. Ask for the scope in writing so you know what the appointment and resulting record will cover.
Who is responsible in a rented commercial property?
Responsibility may be divided between the property owner, commercial tenant, employer and managing agent by the lease and by who controls the equipment or workplace. A contract can allocate tasks, but it should not be assumed to remove statutory duties. Review the lease, appliance ownership and maintenance arrangements before booking.
Can I book one visit for several commercial gas records?
Possibly, provided the engineer holds the relevant competencies and the full scope is agreed before the visit. List every appliance, fuel and record requested rather than booking one generic certificate. We can review the enquiry and confirm whether it can follow one appointment route or needs separate specialist attendance.
