CLG Part L and F consultations, summer 2009 - A summary of the significant proposed changes (Version 2)

TRADA image

CLG forewarned us some years ago that there would be significant amendments in 2010, 2013 plus our final goal of so called 'zero carbon' by 2016.

A reduction of permitted carbon emissions by 2010 was expected and is proposed for 2010. In broad terms the target is 25% lower than at present.

This Construction Briefing summarises the proposed changes to Parts L and F (which will take effect in October 2010) following the CLG consultation.

This briefing explains how the changes will effect buildings both new and existing and what the practical implications to the UK construction industry are likely to be.
