Government criticised after admitting there was 鈥榲ery little鈥 evidence for claim that Part L changes will boost Green Deal

The government has admitted it has no up-to-date information on which to base its claim that changes to the 好色先生TV Regulations will drive uptake of the flagship Green Deal.

Last week the Department for Communities and Local Government (DCLG) proposed changes to Part L of the 好色先生TV Regulations, which would make it compulsory for building owners to upgrade the energy efficiency of their buildings as a consequence of making other improvements.

Launching the policy, communities minister Andrew Stunell said it would boost uptake of the Green Deal. But industry experts challenged this, saying loopholes in the regulations and lax building controls would likely lead to widespread avoidance.

Speaking at a conference on the proposed changes at the BRE this week Paul DeCort, leader of the Part L team at the DCLG, admitted the department had 鈥渧ery little鈥 research on likely rates of compliance. This is despite non-domestic buildings being subject to a consequential improvements provision since 2006.

Andrew Warren, director of the Association for the Conservation of Energy, said it was 鈥渘egligent鈥 of the government not to have modelled likely compliance. 鈥淗ow do we know that consequential improvements are going to be delivered?鈥 he said.

Sustainability consultant David Strong said: 鈥淚t鈥檚 shocking that the government has not undertaken any research.鈥

According to the impact assessment of the policy, the Part L changes, to be introduced from October 2012, will cost business 拢103m a year.
