Commercial gas safety certificates in London
Gas safety inspection for commercial premises — catering kitchens, plant rooms, workshops and offices with gas-fired equipment. The commercial regime is not the same as the domestic landlord duty behind a CP12, and this page does not restate the domestic rules.

This page does not yet state what this service covers.
Haven offers this service, and you can ask us for it. What is missing is the verified detail — scope, the legislation behind it, how often it should be repeated and what it costs. Rather than fill those in from general knowledge and present them as Haven’s position, they are left out until somebody with the relevant competence has checked them.
OUTSTANDING · The statutory basis for commercial gas work, what a CP42 record covers, the engineer registration required, and the inspection interval are all unverified. The reference describes only the domestic CP12 duty, which is a different regime and must not be restated here.
What an CP42 actually records.
This page describes what the service is called and how to ask for it. What a commercial gas safety record covers, which regulations apply to your premises, and what the inspection interval should be have not yet been confirmed by Haven.
If you are a landlord letting a home with gas appliances, the document you need is the domestic gas safety record, and that service has a confirmed price and a stated legal basis.
LEGAL BASIS
Requires technical and legal review
Haven has not yet established which legislation applies to this service, so none is stated here. That is not the same as saying none applies. If you need to know the statutory position before instructing us, ask and we will confirm it in writing rather than guess.
Who this is for, and the properties it applies to.
Commercial premises with gas-fired equipment
Catering kitchens, plant rooms, workshops and any commercial building with gas appliances or pipework.
Not the domestic landlord duty
A rented home needs a domestic gas safety record. The two regimes are separate and the domestic one is not described on this page.
