Housing Delivery Test


The Housing Delivery Test (HDT) is a monitoring tool introduced by the Ministry of Housing, Communities and Local Government (MHCLG) in 2018. It is to ensure that local authorities and other stakeholders are held accountable for their role in ensuring new homes are delivered.

The HDT assesses the number of homes built in local authority areas over the previous three years. It then compares these against the Governments housing requirement calculation for the island. The first HDT 2018 results were published by MHCLG in February 2019 and the IWC scored 71%. The 2019 HDT saw the IWC score 61% and for the 2020 HDT the IWC scored 54%.

Local Planning Authorities that fail to meet delivery targets are required to take appropriate action to address under delivery, with different measures for Councils scoring under 95%, 85% and 75%.

What we have done

In the case of the Isle of Wight Council, our Housing Delivery Test results have three impacts:

The first impact was we had to write an Action Plan to set out the issues of under-delivery and what actions we, as a council, can take to improve delivery of housing across the Island.

The Action Plan reviewed and monitored each year. It includes how the council is under-delivering on our housing requirements.

The Action Plan Monitoring Reports can be downloaded below:


The IWC Action Plan is currently being reviewed and a new plan will be published later in 2021.

The second impact is working out if we have enough land to build 5 years’ worth of houses on, we have to add a buffer of 20% to the 5 year housing number.

Finally the third impact is the application of the ‘presumption in favour of sustainable development’ when making planning decisions, as explained in paragraph 11 (d) of the National Planning Policy Framework (NPPF). The ‘presumption in favour of sustainable development’ is also applied when a council cannot show it has enough available and suitable land to build 5 years’ worth of houses on, which is something the IWC has not been able to show since 2018.
