Code for Sustainable Homes Training (CSH)

Stroma Certification is approved by the Department for Communities and Local Government (DCLG) to provide the required certification to become a Code for Sustainable Homes (CSH) assessor.

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.

Course Information

Stroma Certification offers two courses.

Code for Sustainable Homes Designer Awareness

A 2-day training course only.

This 2-day course provides candidates with a detailed overview of the requirements of the Code and its technical guide. This knowledge can be applied throughout the design process to assist in the achievement of the required rating.

The Designer Awareness course does not include an examination and candidates will not be qualified to conduct CSH assessments.
