Housing Delivery Test

The Housing Delivery Test is an annual measurement of housing delivery in the area of relevant plan-making authorities and its results will be published annually in November by the Ministry for Housing, Communities and Local Government. The annual figure given for the HDT (as percentage) is calculated as follows:

HDT (%) = 

Net homes delivered over three year period


Number of homes required over three year period

Historic records




HDT (%)


Action Plan



20% buffer




None needed




* These are the potential actions:

  • If HDT < 95% - an action plan is needed

  • If HDT < 85% - a 20% buffer to housing supply is needed (in addition to the above)

  • If HDT < 75% (2020 onwards) - presumption in favour of sustainable development (in addition to the above)

** The decision includes a link to the Cabinet meeting (and associated documents) when the decision was taken. It includes a text-only version of the Action Plan.

National Planning Policy Framework

According to the NPPF, paragraph 75, ’to maintain the supply of housing, local planning authorities should monitor progress in building out sites which have permission. Where the Housing Delivery Test indicates that delivery has fallen below 95% of the local planning authority’s housing requirement over the previous three years, the authority should prepare an action plan in line with national planning guidance, to assess the causes of underdelivery and identify actions to increase delivery in future years’. Melton Borough Council has six months to prepare an Action Plan, although this ‘can be prepared at any time irrespective of where it passes or fails the HDT
