Exclusive: Lib Dems analysis shows scrapped zero carbon standard would have saved owners 200 a year

The UK government's decision to allow homes to be built to low standards of energy efficiency cost owners of newly built homes about 234m last year, analysis shows.

The zero carbon homes standard was supposed to come into force in 2016, but the measure, which was introduced under Labour, was scrapped by the Conservative government in 2015.
