Figures revealed by Treasury Minister Ian Pearson show that only a handful of new homes qualified, according to The Times.
Gordon Brown in his last Pre-Budget Report as Chancellor in November 2006 that most new zero-carbon homes would be exempt from stamp duty from 2007.
The building industry has previously raised concerns that Government’s current definition of “zero-carbon” excludes the use of off-site renewables.
This was backed up by the Callcutt Review of house building, published in November 2007 and a report published in May by the UK Green Building Council (UK-GBC).
Paul King, chief executive of the UK-GBC, said: “As Government was warned in late 2007, the definition of zero-carbon is at present too restrictive.
“This is not about dumbing down the concept of zero-carbon or the level of our ambition – far from it – it is about recognising that developers should be able to achieve the same level of carbon savings but through more flexible means.”
The UK-GBC’s report entitled The Definition of Zero Carbon, warned that up to 80% of new homes would not meet the criteria.
It recommended that off-site renewable energy should be allowed, or that developers could pay into a Community Energy Fund.
However, at a fringe meeting at the Labour Party Conference in September this year, Housing Minister Caroline Flint promised a consultation on the final definition of zero-carbon homes.
A spokesman for the UK-GBC told edie: “We hope that the consultation, when it comes out, will be based on report. It should certainly make the definition of zero-carbon more flexible for developers to hit.”
