What is a Water Efficiency Calculation?

A water efficiency calculation can help building owners to work out the total water consumption, per person, per day in a property.  Following guidelines set by Approved Document G under government Building Regulations – Sanitation, hot water safety and water efficiency, all new build projects whether it be new build or conversion must calculate how much water is likely to be used each day.

Using Compliant EPC Ltd’s bespoke water usage calculator, it is now easier than ever to make sure your building is fully compliant with UK regulations.

Why is It Important?

UK Building Regulations state that all new builds need to ensure a specific level of water efficiency.  In line with Approved Document G, building control must make sure that each person in a property receives a maximum of 125 litres of water.

A calculation is crucial for new builds to legally prove that they are compliant.  Without it, a home or building may not pass approval.  Therefore, it is extremely important for project managers to seek calculation as soon as possible.

Approved Document G offers guidelines relating to water efficiency, hot water safety and sanitation.  To safely welcome people into a building, you need to be sure that your water systems are acting efficiently enough!
