Code for Sustainable Homes

Code for Sustainable Homes logo

From 1 May 2008 it is now mandatory for all new homes to be rated against the Code and include a Code or nil-rated certificate within the Home Information Pack.

The Code measures the sustainability of a new home against categories of sustainable design, rating the ‘whole home’ as a complete package.  The Code uses a 1 to 6 star rating system to communicate the overall sustainability performance of a new home.  The Code sets minimum standards for energy and water use at each level and, within England, replaces the EcoHomes scheme, developed by the Building Research Establishment (BRE).

The Code also gives new homebuyers better information about the environmental impact of their new home and its potential running costs, and offer builders a tool with which to differentiate themselves in sustainability terms.

Since April 2007 the developer of any new home in England can choose to be assessed against the Code.

Communities and Local Government have published a Greener Homes for the Future Leaflet which highlights what the Code is, how it works and what it means to have a mandatory rating for new homes.
