Part G Compliance

Water Use Calculations

Water Use Calculations

To comply with Part G of Building Regulations, all new dwellings need calculations to show that water use per person per day does not exceed 125 litres.

Energise can check your dwelling design and produce water use calculations to show the maximum flowrate of taps and showers, capacities of baths, dishwashers, washing machines, and the flush volumes of dual flush and single flush WCs.

This specification can then be used to select sanitary ware, taps, showers, baths and appliances to ensure compliance with Part G.
