CIOB have responded to the Department for Environment Food & Rural Affairs (DEFRA) Review of Water Efficiency Standards in the Building Regulations 2010.

DEFRA is exploring whether the Building Regulations 2010 could be amended to tighten water efficiency standards and enable consumers to use less water and save on their water and energy bills.

This public consultation includes an option to revise the minimum Water Efficiency Standard in new houses through fittings from 125 l/p/d to 105 l/p/d, and the optional technical standard from 110 l/p/d to 100 l/p/d. It includes a call for evidence on water reuse systems in new developments, to enable even greater water efficiency. 

CIOB's response, which can be downloaded below, was informed by the Sustainability Advisory Panel and expert member input. We are broadly supportive of amending the minimum water efficiency standard in new homes through fittings from 125 l/p/d to 105 l/p/d, noting many are already reaching this standard and going beyond.
