What is a Water Efficiency Assessment? 

Water efficiency assessments help ensure that new homes use water responsibly by limiting the amount of water used per person each day. We calculate this using details such as the flow rates of taps, showers, and toilets to ensure your project meets the current standards for Building Regulations compliance.

Why iS WATER EFFICiency important?

In the UK, water efficiency in new buildings is regulated by Approved Document G of the Building Regulations, focusing on sanitation, hot water safety, and water efficiency. This document sets standards for the design and construction of buildings to minimize water consumption in new dwellings. The regulations aim to ensure that new homes do not exceed a certain water consumption threshold, which is generally 125 litres per person per day, but can be stricter (e.g., 110 litres) based on planning permission or local authority requirements. 

Key aspects of water efficiency regulations:

Water Efficiency Calculator:This method is used to calculate the water consumption of a new dwelling, taking into account various factors like fixtures, appliances, and occupancy levels. 

Fittings and Appliances:The regulations emphasize the importance of using water-efficient fittings and appliances in new homes, such as low-flow showers, toilets, and washing machines. 

Water Harvesting:While not mandatory, rainwater harvesting is encouraged as a way to reduce reliance on potable water and can contribute to meeting water efficiency targets.
