Water Calculations (New Service by EAL)
Why do I need water calculations?
They are required as Part G of the Building regulations.
On applying for planning permission applications require a water calculation.
What is Part G of the Building regulations?
The 2010 edition of Approved Document G (sanitation, hot water safety and water efficiency) mandates to have a predicted water consumption of 125 litres/person/day using the methodology outlined in the “Water Efficiency Calculator of New Dwellings”. The 'Water efficiency calculator for new dwellings' is the Government's national calculation methodology for assessing water efficiency in new dwellings in support of The Code for Sustainable Homes and the Building Regulations.
When do I need to do a water calculation?
