Statistics on the code for sustainable homes and average energy efficiency (SAP ratings) for homes in England, Wales and Northern Ireland.
The latest official statistics on the code for sustainable homes and average energy efficiency (SAP ratings) were released on 22 February 2011.
Statistics in this release relating to the code for sustainable homes show the number of dwellings that have been certified to the standards set out in the ‘code for sustainable homes: technical guidance’.
A number of errors were contained within these published statistics.
These errors related to the number of code certificates (at both design and post-construction stage) issued by 22 of the 25 Welsh planning authorities. Although these errors affected the number of cases for individual planning authorities, it did not affect the overall total of cases in Wales. The statistics for England and Northern Ireland remain unchanged. The cumulative and quarterly data commentary is therefore unchanged as it relates to national statistics which remain the same.
We apologise for the error, caused by an anomaly in the transfer of data, which has now been rectified. The document ‘Table of Welsh statistics changes’ sets out the data as originally published and as amended.
The published quarterly statistics have now been amended with the changes being denoted by an ‘R’ in the appropriate column. These were published 26 August 2011.
