Industry sources suggest that there could be delays in the publication of revisions to Part L – the regulations that govern the energy efficiency of buildings.
In March, the government said it would publish a detailed plan, setting out its response to its 2012 consultation on changes to Part L.
The Part L regulations set out the energy efficiency requirements for buildings and are critical to the introduction of the zero-carbon homes requirement in 2016.
The government’s preferred option in its consultation, which closed in April 2012, would see an eight per cent rise in carbon efficiency standards for new homes and 20 per cent for commercial buildings.
