Water Efficiency

eco friendly building

Since April 6th 2010, all residential houses and conversions are required to meet specific water usage and efficiency targets in order to satisfy Part G of the Building Regulations. In simple terms this means that you will need to demonstrate to building control that water usage within the property does not exceed 125 litres per person per day.

With our in-house team of fully trained assessors, ATSPACE can provide you with a fast turnaround service for all your Water Efficiency Calculations, including submission of the calculations direct to your relevant building control authority.

As part of our calculation service, we take into account of all aspects of water usage within the property including, flow rates of taps and showers, washing machine and dishwasher usage along with WC flush rates. Our assessors can even make recommendations that will help you in achieving that required water consumption target.

When linked to our Residential Air Pressure Testing and Sound Testing services, ATSPACE are able to offer a full one-stop-shop service that is comprehensive, price-competitive and, above all, focussed upon you achieving success.
