Critics say the costs could have been avoided if ministers had agreed to bring in low-carbon standards sooner
Householders buying brand new homes in the next four years are likely to find an unpleasant surprise awaiting them in the future: homes built today will have to be retrofitted with energy efficiency measures and low-carbon technology, at an average cost of more than £20,000.
The extra costs will amount to more than £20bn for the whole of the UK, if the government’s targets of building 300,000 new homes a year are met. Critics say the costs could have been avoided if ministers had agreed to bring in low-carbon standards sooner.
