Code for Sustainable Homes, July-September 2010
Code for Sustainable Homes
Statistics relating to the Code for Sustainable Homes (the Code) show the number of dwellings that have been certified to the standards set out in the Code Technical Guide. Code certificates are issued at two stages, the design stage and post construction stage.
Dwellings are awarded a star rating (one star being the lowest achievable level and six stars being a zero carbon home). If a dwelling does not achieve the mandatory standards and/or does not reach the minimum score for a one star rating, it will receive a certificate with no stars. The assessment and certification of Code homes is undertaken by the 1372 assessors, who are licensed by BRE Global Ltd or Stroma Accreditation Ltd.
Between April 2007 and September 2010:
- Across England, Wales and Northern Ireland, 31,469 dwellings have received a three star rating at the design stage and 287 dwellings have received a six star rating (i.e. zero carbon home).
- Across England, Wales and Northern Ireland, 11,361 dwellings have received a three star rating at post-construction stage and 19 dwellings have received a six star rating (i.e. zero carbon home).
- A total of 87 per cent of the certificates at design stage and 88 per cent of those at post-construction stage have been awarded at Code level 3 since April 2007.
- Of the 36,099 certificates issued at the design phase, 516 were issued in Wales, whilst 84 of the 12,876 post-construction certificates were issued in Wales.
Average energy efficiency (SAP) rating of new homes
SAP refers to the Government’s ‘Standard Assessment Procedure’ for assessing the energy performance of dwellings. The SAP rating is expressed on a scale of 1 to 100 – the higher the number, the lower the running costs.
The energy efficiency rating, on a quarterly basis, is volatile due to a number of factors including the mix of dwelling types, the mix of heating systems used in new developments and the location of those developments where there are a small number of new homes being assessed in some of these categories.
The key points for April to September 2010 are:
- The average energy efficiency, SAP rating, of new homes in Wales was 79.4 compared to 79.3 in England.
- Across England and Wales, the average energy efficiency (SAP rating) of new homes varied from 76.8 in the East to 81.5 in the North East.
- In Wales, the average energy (SAP rating) by dwelling type, ranged from 76.8 for bungalows to 79.9 for houses.
- Overall, England had higher average SAP ratings than Wales for houses, but lower average SAP ratings than Wales for flats, bungalows and maisonettes.
Please note these figures are not classed as National Statistics.
