Consultation description

We want to know what you think about proposed changes to Water Efficiency Standards for new homes.  

We are proposing a plan to strengthen Water Efficiency Standards in the Building Regulations 2010, Part G, to require tighter standards in new homes.  

It includes an option to revise the:  

  • Water Efficiency Standard in new homes from 125 litres per person per day to 105 litres per person per day 

  • Optional Technical Standard from 110 litres per person per day to 100 litres per person per day

We also want to gather more information on enabling water reuse systems in new developments to enable even greater water efficiency in homes.
