Use this checklist at concept and detailed-design stages. It is a coordination prompt, not a substitute for the Approved Documents or a project assessment.

1. Confirm the route. Record each building, the building-control application and evidence of commencement. Do not assume a whole phase has the same transition status.
2. Set the geometry. Coordinate site plan, floor plans, elevations, sections, orientation and dwelling types. Keep a revision register.
3. Agree the fabric. Identify wall, roof and floor build-ups, junction strategy, windows and doors. Flag provisional choices.
4. Coordinate ventilation and overheating. Reserve space and routes early; consider glazing and shading alongside daylight.
5. Choose services together. Heating, hot water, controls and renewable electricity affect space, roof and electrical design.
6. Check performance early. Assess while design options can still change, then update the model as specifications firm up.
7. Keep an as-built trail. Collect final specifications, commissioning information and changes for completion-stage assessment.

The government circular highlights low-carbon heating, high efficiency and on-site renewable electricity. Request a quotation, then email your drawings to info@uksaps.co.uk and tell UKSAPS which decisions remain open.
