Code for sustainable homes technical guide: Code addendum (2014) England

This publication was withdrawn on 22 April 2015

Following the technical housing standards review, the government has withdrawn the code for sustainable homes, aside from the management of legacy cases.

Legacy cases are those where residential developments are legally contracted to apply a code policy (eg. affordable housing funded through the national Affordable Housing Programme 2015 to 2018, or earlier programme), or where planning permission has been granted subject to a condition stipulating discharge of a code level, and developers are not appealing the condition or seeking to have it removed or varied. In these instances it is possible to continue to conduct code assessments.

Details of the new approach to the setting of technical housing standards in England were announced on 27 March 2015 and a new set of streamlined national technical standards were published. A planning written ministerial statement was also published which outlined the government’s policy on the application of these technical standards for plan making and decision-taking.

The code for sustainable homes webpage is available for the purposes of administering legacy cases only.

This document is an addendum to the Code for sustainable homes which brings it into line with regulatory or national guidance changes.



This addendum brings the Code into line with regulatory or national guidance changes that have occurred recently. In particular, to Part L of the building regulations, to reduce the need for Code users to duplicate work. It should be read in conjunction with the Code technical guide, November 2010.

Once the Code addendum (2014) England is implemented (this applies to England only), the following arrangements should be used to determine which scheme version new developments are registered against:

  1. For a period of 1 month following implementation of the addendum (2014) England it will be possible to register new developments under either of the November 2010 scheme, or the addendum (2014) England.

  2. Where evidence is provided showing that all dwellings are eligible to be assessed for compliance with the 2010 version of Part L of the building regulations, it will be possible to register developments against the November 2010 version of the Code.

  3. After the period of 1 month from the implementation date of the Code addendum (2014) England, it will be necessary for all developments, apart from those that meet the requirements described in point 2 above, to register against the Code addendum (2014) England.

The arrangements above are designed to allow alignment between the Part L building regulation and the appropriate Code version applied to developments. This is intended to minimise the number of instances where it is necessary to provide both SAP 2009 and SAP 2012 calculations to assess the energy performance of the same dwelling. For developments registered against the November 2010 scheme version they will be required to use SAP 2009 to assess energy performance unless there is a building control requirement to use a different building regulation.

From 6 April 2014, it is no longer possible to register new schemes against Part L version 2010, except where work has already (physically) commenced before 6 April 2014, or where a building notice, full plans, initial notice or plans certificate has been given to a local authority before 6 April 2014 and carried out in accordance with the plans or notice given, so long as the work is commenced by 6 April 2015.

Alternatively, developments registered against previous Code scheme versions can be re-registered for free against the Code addendum (2014) England, to align with latest building regulations.
