The Department for Communities and Local Government (DCLG) has finally unveiled changes to Part L of the building regulations will come into effect in April 2014.

Under proposals announced last month new build homes will have to be six per cent more efficient than under current regulations, two per cent below the eight per cent target set out in the government’s original proposals to tighten carbon emission standards.

Dr Ali Arasteh, business unit technical manager for Siniat, said: “We’re still going in the right direction.  Now, the onus must be on showing the value and importance of delivering energy efficient homes and buildings to force energy efficiency higher up the political agenda in future.”

The changes will introduce an uplift in efficiency standards of nine per cent for non-domestic buildings, lower than the 20 per cent improvement proposed in the consultation which closed in April 2012.
