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.

A useful quotation starts with a clear project picture. You can approach UKSAPS before every specification is final, provided assumptions and drawing revisions are labelled.

At quotation stage

Send the site address and brief, site/location plan, current floor plans, elevations and sections with dimensions, dwelling count and type, planning/building-control stage and expected programme. For a multi-plot site, add a plot or house-type schedule.

For the assessment

The assessor may need construction build-ups, window and door schedules, glazing, thermal-bridge strategy, ventilation design, heating and hot-water system, controls and renewable generation proposals. Ask which details are needed now and which can follow. Send revisions when the design changes.

If your drawings are incomplete

Share what you have and list the open decisions. UKSAPS can say whether it can quote now or needs more information. Submit your project details through the quotation form, then email your drawings to info@uksaps.co.uk with your name and project postcode. Drawing upload on this site is temporarily unavailable.

New practical draft for UKSAPS review, 21 October 2026.

For a multi-plot scheme, the important question is often which requirements apply to each building. Government Circular 01/2026 describes transitional protection for non-higher-risk work where a qualifying building-control notice or application was given before 24 March 2027 and work on the relevant building commenced before 24 March 2028. One start on site does not automatically settle the status of every plot.

Build a plot schedule

Record each building identity, house type, application/notice reference and date, planned and evidenced commencement, drawings and proposed specification. Confirm with building control how the provisions apply; higher-risk building work follows separate rules.

Keep the assessment aligned

Reused house types can share design information, but orientation, fabric or services may vary by plot. Track revisions centrally and flag changes before they are built.

UKSAPS can discuss assessment scope if you supply the plot schedule and current drawings. Send scheme details. This guide does not decide transitional eligibility.

The 2026 requirements put low-carbon heating, high energy efficiency and on-site renewable electricity at the centre of new-home design. The applicable Approved Document and individual project determine the technical solution.

Heat pump planning

Coordinate plant position, access, distribution temperatures, hot-water storage, controls and commissioning responsibilities. The approved guidance addresses building-services efficiency, heat-pump controls and heat loss from low-carbon heating systems.

Solar PV planning

Consider usable roof geometry, shading, structure, electrical coordination, inverter location and a realistic system specification. The 2026 amendments add a functional requirement for on-site renewable electricity in new dwellings and buildings containing dwellings; guidance describes compliance routes and exceptions.

Assess the whole dwelling

Fabric, glazing, ventilation, heating and renewable generation interact. Share the proposed package with an assessor before ordering equipment, then update the calculation if the installed specification changes.
