Code for Sustainable Homes

The Code for Sustainable Homes (CSH) is an environmental assessment method for rating and certifying the performance of new homes based on BRE Global's EcoHomes scheme. It is a Government owned national standard intended to encourage continuous improvement in sustainable home building.

See the FAQs on our housing standards update page on the BRE website for an update on the Government's recent annoucement on the Code.


In March 2015, BRE unveiled the Home Quality Mark. Click here for details 

This national quality mark will give people the confidence that the new homes they are choosing to buy or rent are well designed and built and cost effective to run. It will also allow house builders to demonstrate the high quality of their homes and to differentiate them in the marketplace.




BRE Global act as advisors on issues related to maintenance and development of the technical contents of the CSH standard and manage implementation of the scheme under contract to the Department of Communities and Local Government (DCLG).

Scope and Scoring

 The CSH covers nine categories of sustainable design:

  • Energy and CO2 emissions (M),
  • Water (M),
  • Materials (M),
  • Surface Water Run-off (M),
  • Waste (M),
  • Pollution,
  • Health and Wellbeing (M),
  • Management,
  • Ecology.

There are mandatory performance requirements in 6 catergories (denoted by an M above). All other performance requirements are flexible. It is possible to achieve an overall level of between zero and six depending on the mandatory standards and proportion of flexible standards achieved.


Assessments are carried out in two phases:

  1. An initial assessment is carried out at the design stage. This is based on detailed documentary evidence and commitments which results in an interim certificate of compliance.
  2. Final assessment and certification is carried out at the post construction stage. Based on the design stage review, this includes a confirmation of compliance, including site records and visual inspection, and results in a final certificate of compliance.
