The housing delivery test aims to measure how effectively each local authority is delivering housing. It works by comparing each councils' level of housing delivery - using the the net additional dwelling figures - over a three-year period to the total number of homes required.
The test results for the 2016-19 period were published by the Ministry of Housing, Communities and Local Government (MHCLG) last week, having been postponed for three months following the December general election. They are the second annual test results that the MHCLG has published.
Under the test, allauthorities delivering under 95 per cent of their housing requirement are penalised, which means they will have to at minimum produce an action plan showing how they will improve their housing delivery performance over the next year.
The test results show that 109 authorities - exactly 33 per cent - scored under 95 per cent, meaning two-thirds escaped any penalty.
The penalties take effect from the moment the results are published, according to the 2018 National Planning Policy Framework (NPPF).
In February last year's 2018 delivery test results, 219 councils escaped any penalty by delivering over 95 per cent of their requirement.
But of this 219, our study found that 22 councils would in the 2019 test drop under 95 per cent and thefore have to produce an action plan for the first time.
Planning's December 2019 research estimating the 2019 test results predicted that 23 councils would drop under 95 per cent and thefore have to produce an action plan for the first time.
The first test results for the 2015-18 period were published in February last year, three months late.
