Sustainable code

Code for Sustainable Homes

A large proportion of the UK's carbon-dioxide emissions come from the energy used to light, heat and run our homes. The aim of the Code for Sustainable Homes is to improve the environmental sustainability of homes by setting a national standard for comparison and reduce the impacts in running them. Code rating for new homes is now mandatory and replaces the EcoHomes scheme.

The Code works by using a sustainability rating system, indicated by stars ranging from one star level to the highest which is a six star level. Six stars would achieve a zero carbon home. By 2016, the Government expects all new homes to be zero carbon.

The Code measures the sustainability of a home against the nine categories set out below:

  • Energy CO2
  • Water
  • Materials
  • Surface water run-off
  • Waste
  • Pollution
  • Health and well-being
  • Management
  • Ecology

Requirements

  • Transport
  • Water
  • Materials and Waste
  • Land use and Ecology
  • Pollution
