Answers before you book

Certificate names can be confusing, particularly when a property is changing tenant, applying for a licence, renewing insurance or being managed on behalf of an owner. These guides explain the practical starting point, the information an engineer may need and when a combined enquiry is more sensible than separate bookings.

They are general guidance, not a substitute for an inspection or a site-specific decision. Send the address, property use, equipment details and deadline so the correct route can be checked.
