What Is Included in a Water Efficiency Calculation?
The calculation uses the flow rates, flush volumes and capacities of the proposed fittings and appliances to estimate daily water consumption per person.
Accurate product information allows the assessor to determine whether the dwelling meets the applicable Part G target before installation.
WC flush volumes
Basin tap flow rates
Kitchen tap flow rates
Shower flow rates
Bath capacities
Washing machine consumption
Dishwasher consumption
Alternative water supplies where applicable
Complete the Calculation Before Ordering Sanitaryware
Completing the assessment at design stage allows non-compliant fittings to be identified before they are purchased or installed.
Where the proposed specification exceeds the water-consumption target, the assessor can suggest suitable changes to flow rates, flush volumes or appliance usage figures.
Early assessment helps avoid replacement costs, Building Control delays and last-minute specification changes.

Important Water Calculation Information
Water efficiency results depend on the accuracy of the sanitaryware, appliance and manufacturer information provided. Product substitutions or specification changes can affect compliance and should be referred back to the assessor. The report demonstrates predicted water consumption for the proposed dwelling and does not replace correct product installation or Building Control approval. One Stop Consult provides consultancy and coordination support through experienced water-efficiency assessors.
