Commercial gas safety certificate in London: what the price includes

  • 01
    Commercially qualified

    Commercial catering and heating tickets, not domestic engineers stretching their scope.

  • 02
    Out-of-hours by default

    Inspections around service and trading hours, kitchens certified between lunch and dinner if that's what the rota needs.

  • 03
    Interlock and ventilation checks

    Commercial kitchens need gas interlock systems proven, not assumed, it's the first thing EHOs ask about.

  • 04
    Compliance files

    Records kept and re-issued on demand for insurers, EHOs and licensing.

  • 05
    Commercial catering and plant are separate qualifications

    Commercial kitchens, warm-air heaters, large boilers and mobile catering each require their own competency beyond domestic registration. We hold the commercial categories, so a pub kitchen with a six-burner range and a warm-air unit is a single visit rather than three contractors.

Local conditions we work around

Commercial gas work is a different qualification from domestic, and the certificate reflects the appliance class, catering, plant or warm air, rather than being one document. In London the practical constraints are access and trading hours: kitchens that cannot close during service, plant rooms shared between leaseholders, and meters controlled by a managing agent. We schedule around trading and confirm the meter and isolation arrangements before attending so the visit is not wasted.

Commercial gas safety certificate in London, your questions

Is a commercial certificate legally required?
Yes, duty-holder obligations under the Gas Safety Regulations apply to business premises, insurers require the records, and Environmental Health will ask for them. Annual as a floor; some insurers and kitchens need more frequent checks.
What does commercial certification cost?
From £149 per appliance set for small premises (café, salon, office boiler). Full catering lines and plant rooms are scoped and quoted, no per-appliance ambushes on the day.
Our kitchen has no interlock, problem?
For a commercial kitchen, yes: current standards expect gas proving/interlock with the ventilation. We quote the installation alongside the certificate rather than failing you and leaving.
How is a commercial certificate different?
It covers appliances above domestic input ratings and is assessed against different standards, including ventilation and interlock requirements for catering. It also usually involves a gas safety interlock test on kitchen extraction, which does not exist in a domestic check.
Will you have to close my kitchen?
Not usually, and we schedule outside service hours precisely so we do not. If an appliance fails and has to be capped, we tell you immediately and prioritise getting it back rather than leaving you closed until the paperwork arrives.
Do I need a gas interlock?
If you have commercial catering appliances, almost certainly. The interlock shuts off gas if extraction fails, and environmental health and your insurer will both ask about it. We test it as part of the certificate and quote to fit one if there is not a working system.
