Consultation on creating more water-efficient homes

The government has launched a consultation that will propose changes to Building Regulations that could see new homes fitted with water-saving features such as aerated taps and showerheads, and dual flush toilets.

The change to the design standard will make new build housing more water efficient, equivalent to 20 litres per person per day.  The small measures will also help the environment by reducing the amount that needs to be taken from rivers, lakes, and delicate chalk streams for public supply.

The 12-week consultation looks to amend the current Building Regulations 2010 Part G2, which are insufficient to meet the parallel challenges of housing delivery and water conservation.

A reduction of 20 litres per person per day could see an additional 1,000 new homes unlocked for every 5,250 homes built.  

The measures will support the government’s commitment to reduce water usage in England by 20% per person per day by 2038. It also puts us on track to use just 110 litres per head of the population by 2050.

Future innovations, such as using harvested rainwater to flush home toilets, are also being considered in a call to evidence that is running alongside the consultation.

England has seen seven consecutive months of below-average rainfall, with five areas in drought and more expected to follow soon despite the recent rain. Climate change and increased water demand means the nation needs to become more efficient with the water it has.  

Defra has worked closely with the Ministry for Housing, Communities and Local Government (MHCLG) to develop the consultation and ensure it supports housebuilding goals.

Dr. Tom Dollard, Chair, Good Homes Alliance welcomed the consultation saying: 
Our membership is facing real challenges in delivering new homes due to a lack of water capacity in their areas.  

"If we are to meet the Government housing delivery targets and unlock economic growth then we must start building more ‘water smart’ homes and neighbourhoods."
