What is the Code for Sustainable Homes?

CSH drives improvement in building practice by providing a comprehensive measure of housing sustainability. The aim of the Code is to limit the environmental impact of new build dwellings, by ensuring real improvements in key areas such as carbon dioxide emissions, waste, water usage and environmental impact. The role of a CSH assessor is to accurately evaluate new build dwellings against a range of criteria in order to generate a Code rating and report.

Why join our CSH Certification scheme?

Scheme members undergo auditing at regular intervals to ensure consistency and high standards. We also provide free access to a professionally developed software to assist our Code assessor members with creating Code for Sustainable Homes reports.
