Professionals reference this PDF to ensure design compliance during the RIBA stages 3 and 4. It is typically integrated into the technical design package as a primary source for specifying sanitary hardware, hot water storage, and pipework layouts. Designers should consult the document to verify that proposed bathroom and kitchen configurations align with legal requirements for water safety and consumption limits before submitting planning or building control applications for new builds or major renovations.

Engineers and architects utilize this guidance in residential developments, hotel projects, and office fit-outs across England. It is essential for specifying bathroom fixtures, kitchen drainage, and hot water systems that must pass local authority inspections. By embedding these standards into the design phase, teams avoid costly rework and ensure that sanitary facilities are both functional and compliant with the latest UK building codes. Professionals often search for this document when verifying water usage targets or designing complex hot water distribution networks.
