Before you use this sheet
Use this as a project file prompt, not as proof that the work is compliant. Fill it in before speaking to building control, your designer, your builder or a registered installer so the conversation starts with the evidence that matters.
- Write down the project address, proposed work and whether the work has already started.
- Record who is responsible for drawings, calculations, applications, inspections and certificates.
- Keep copies of source checks, installer registrations, inspection dates, photographs and completion paperwork.
- Re-check the official source links if the project scope changes or work starts later than expected.

- Confirm whether the work involves a flat, common part, fire separation, structural element, public sewer, party wall or higher-risk-building route.
- Keep certificates and inspection records because they may matter when selling the home.
