Regularisation Risk Triage

How to use the result

Use the result as a short briefing note, not as a decision to start work. The useful part is the set of next questions: who is applying, who is certifying, what needs drawings or calculations, and what must be inspected before it is hidden by finishes.

If the result points to a competent person route, check the installer registration before the work is booked and ask what certificate will be issued. If it points to full plans or building notice, ask building control what they expect to see before the first inspection. If it points to regularisation, gather evidence before asking whether the work can be considered.

Answers that can change the route

• A small project can become higher risk if it affects structure, escape routes, flats, fire separation, public sewers or hidden drainage.
• A self-certification route can fail if the installer is not registered for the exact work being done.
• A building notice can become uncomfortable where the builder has not priced drawings, calculations, inspections or remedial work.
• A missing certificate issue is easier to discuss when you have dates, invoices, photos and installer details ready.
