Tell us about the gas appliances on site and we'll match you with Gas Safe registered commercial engineers. Compare no-obligation quotes in about a minute, and get the inspection and safety record your insurer, landlord and the law expect.
If there are gas appliances at a place of work you control, you have a legal duty to keep them, the pipework and the flues maintained in a safe condition. An annual inspection by a Gas Safe registered engineer qualified for commercial work, recorded on a non-domestic gas safety record (commonly a CP17, or a CP42 for catering equipment), is the recognised way to meet and evidence that duty.
Maintained by the ComSurv team and checked against UK government, HSE and professional-body sources. ComSurv is a matching service, not a firm of surveyors or contractors. General information, not legal advice.
A record, issued by a Gas Safe registered commercial engineer after inspecting and testing the gas installation, confirming whether the appliances, pipework and flues are safe to use. For non-domestic premises it is usually a CP17, with a CP42 for commercial catering equipment.
Gas appliances, pipework and flues at work must be kept in a safe condition.

Compare no-obligation quotes and book the provider that's right for you.
The engineer inspects each gas appliance, the installation pipework and the flues, checks operating pressures, ventilation, flue performance and safety devices, and carries out a tightness test where appropriate. Anything unsafe is classified and made safe. You receive a gas safety record listing every appliance checked, the results and any defects or remedial work required.
A domestic engineer cannot sign off your commercial boiler.
Gas Safe registration is specific to the type of work. Commercial heating plant and catering equipment need an engineer whose card lists those non-domestic categories, and a record issued by anyone else is not worth the paper it is printed on. We match you with engineers registered for the appliances you actually have.
