The Code for Sustainable Homes was launched in December 2006. It replaced EcoHomes in England since April 2007. The aim is to make the Code for Sustainable Homes as a single standard to achieve sustainable building for new build homes in UK.
The Code for Sustainable Homes set 6 levels of efficiency, with level 6 being zero carbon. By 2010, UK aims to achieve 25% improvement, which is Level 3, according to Building Regulations. By 2013, 44% improvement, equalling Level 4, in energy performance will be achieved. Further, all new houses are aimed to achieve zero carbon by 2016.
