Gas safety inspection and certification for catering kitchens, offices, shops and plant rooms — carried out by commercially qualified Gas Safe registered engineers, at times that don't interrupt trading.
Why it matters
Any business premises with gas — a restaurant or takeaway kitchen, an office with a gas-fired heating system, a shop, a plant room serving a larger building — needs its installation inspected and certificated by an engineer holding the right commercial Gas Safe qualifications. Domestic tickets do not cover commercial appliances, meters or pipework, however experienced the engineer.
The certificate is rarely optional in practice. Insurers make current gas certification a condition of cover; landlords write it into leases as a tenant obligation; environmental health officers expect it when inspecting food businesses; and premises licensing can turn on it. When the premises is let, the landlord's statutory duty to have appliances and flues checked every 12 months applies in the commercial world just as it does in housing.
If you also let residential property, the equivalent domestic document is the landlord gas safety certificate (CP12) — we handle both, so mixed portfolios can keep everything with one contractor.
Premises we certify
CP42-type catering inspections for restaurants, takeaways, cafés and commercial kitchens: ranges, fryers, ovens, grills and water boilers checked appliance by appliance, alongside the pipework and the ventilation system they depend on. The certificate is the document your insurer and the environmental health officer will ask for.
Gas-fired heating, warm-air units and water heaters in workplaces and retail units, inspected and certificated for the employer's health and safety file and the landlord's lease requirements. Small installations are often a single short visit — we confirm scope before quoting so there are no surprises.
Boiler plant serving blocks, schools and commercial buildings: appliance checks, flue inspection, and purge and tightness testing of larger-volume pipework carried out to commercial procedures. We coordinate with building managers so heating and hot water outages are planned, brief and communicated.
Running an HMO or mixed-use building? Commercial plant often sits alongside residential duties — see our HMO certificate management and fire risk assessments to keep the whole building compliant from one point of contact. Electrical inspection for business premises is covered by a commercial EICR.
Common questions
It depends on the type of premises, the number of appliances and the size of the pipework installation — a small café kitchen is a very different job from a plant room. Send us what the premises is, roughly what gas equipment it has and the postcode, and we'll reply with a fixed quote, usually the same working day.
Commercial appliances, meters and pipework fall outside the scope of domestic qualifications, so the engineer must hold the relevant commercial Gas Safe categories. The testing is different too: larger pipework is purged and tightness tested to commercial procedures, and catering equipment has its own checks. A domestic engineer cannot lawfully sign off commercial work.
In practice, yes. Insurers, landlords and environmental health officers all expect current certification for catering appliances, and a lease will almost always require it. We check each appliance, the ventilation interlock where fitted, and the pipework, and issue the catering certificate your insurer and licensing officer will accept.
Annually is the standard cycle — it is what insurers and leases generally require, and where the premises is let, the landlord's duty to have appliances and flues checked every 12 months applies just as it does in housing. We track your renewal date and remind you before it falls due.
Yes. Gas checks in a working kitchen or shop floor mean isolating appliances, so we schedule visits around service — early mornings before prep, closed days or after trading — and agree the timing with the site manager in advance so nothing is switched off mid-service.
