Water Efficiency Calculations

“We have been completely happy with the service provided and would happily use Act again, in fact, we may well be in touch some time soon!”

– Residential Homeowner, Mr Tomlinson

The Government updated Part G of the Building Regulations in April 2010. This sets a whole building standard of 125 litres per person per day for domestic buildings. This comprises internal water use of 120 litres per person per day, and in that respect is in line with Code Levels 1 and 2, plus an allowance of 5 litres per person per day for outdoor water use. This will be specified using the methodology set out in the ‘Water Efficiency Calculator for New Dwellings’ also used for the Code for Sustainable Homes.

Act Surveyors can provide bespoke Water Efficiency Calculations reports for dwellings and issue notice of Water Efficiency as required under The Code for Sustainable Homes. We also provide advice on a number of measures to help reduce indoor water use, with methods such as flow restrictors, low flow shower heads, low flush WCs etc. or efficient, practical and cost effective appliances and recycling of grey water and rainwater.
