Water Calculation

Demonstrating Compliance with Part G of the Building Regulations in England and Wales

Ensuring compliance with water efficiency regulations is essential for any new build, renovation, or conversion project. Part G of the Building Regulations requires that all new dwellings in England and Wales meet a calculated water consumption target to promote sustainable water use. Our expert water calculations service provides accurate assessments to ensure your project meets these requirements with ease.

What Are Water Calculations?

Water calculations assess the predicted potable water consumption of a new dwelling, expressed in litres per person per day (L/person/day). The standard requirement is a maximum of 125 L/person/day, or 110 L/person/day where stricter planning conditions apply. These calculations consider all water-consuming fittings and appliances within a property, including taps, showers, toilets, baths, washing machines, and dishwashers.
