Water Efficiency Calculations

If your building control officer requires a water efficiency calculation to satisfy Part G of the building regulations, give us a call. We can do this for a fixed fee of just £20 + VAT. Turnaround is within 24 hours, usually the same day.

What is Part G of the Building Regulations?

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.

What does Part G of the Building Regulations mean for me?

If you are building a new home, you must ensure that it will have a predicted water consumption of less than 125 litres/person/day. We can prove compliance, usually within a 24 hour period.
