Code for Sustainable Homes: Guidance

The guidance which set out the current assessment process and the performance standards required for the Code is: The Code for Sustainable Homes: Setting the Sustainability Standards for new homes that was published on 27 February 2008.

Technical Guidance

The Code for Sustainable Homes: Technical guide sets out the requirements for the Code, and the process by which a Code assessment is reached. It aims to make gaining a Code assessment as simple, transparent and rigorous as possible.

The latest version is the ' 2010 ' Technical Guidance (see downloads section below) which comes into effect  from the 11 November 2010. It replaces the 'May 2009 Version 2' of the Code Technical Guidance (see Archived publications section below). A summary of the main changes made to the Code are provided in The Code for Sustainable Homes: Summary of the changes to the Technical Guidance - 2010  publication (see downloads section below).

In order to establish whether the previous or the new version of the Code applies for you, please see The Code for Sustainable Homes:Transitional Arrangements (PDF 30Kb) guidance document

The Code for Sustainable Homes now also uses the 'Water Efficiency Calculator for New Dwellings' (see downloads section below) as the Assessment Methodology for WAT1. The Water Calculator tool (Excel, spreadsheet) is available below to download and use.

Note:  The Calculator is not a design tool for water supply and drainage systems. It is also not capable of calculating the actual potable water consumption of a new dwelling. Behaviour and changing behaviour can also have an effect on the amount of potable water used throughout a home.
