Housing Delivery Test: 2021 measurement technical note

Published 14 January 2022

Applies to England

Introduction

This document sets out the technical process followed in order to calculate the 2021 Housing Delivery Test measurement in line with the published Housing Delivery Test rule book.

This document should be read alongside the Housing Delivery Test rule book and aims to explain how this year’s result is calculated with a step-by-step explanation of the process as opposed to setting out the policy in detail.

All terminology in this document mirrors that contained in the Housing Delivery Test rule book.

The Housing Delivery Test measurement is published annually by the department. The Housing Delivery Test period covers the previous 3 financial years; in the case of the 2021 measurement, the years are 2018/19, 2019/20 and 2020/21.

The Housing Delivery Test compares the net homes delivered over 3 years to the homes required over the same period.

Housing Delivery Test (%) =

Total net homes delivered over 3 year period

divided by

Total number of homes required over 2 year 7 month period*

*For the 2021 measurement, there is a reduction in period for measuring total homes required – usually this would be measured over a 3-year period, but an 8-month period has been used for the 2020/21 monitoring year. This is to account for the considerable variations in levels of housing delivery as local planning authorities and construction industry faced disruption on a national, regional, and local level due to the pandemic. Additionally, an 11-month period has been used for the 2019/20 monitoring year. This was to account for disruption to housing delivery and monitoring caused by the first national lockdown in March 2020.

The calculation uses published statistics and data collected by the department from local planning authorities, National Parks, and Development Corporations for this purpose.

Calculating the homes required

To calculate the total net homes required over the 3-year monitoring period, the calculations draw on:

• Local housing need. This is calculated in line with the Housing and Economic Needs Assessment Planning Practice Guidance. For the 2021 Housing Delivery Test (HDT), the test years 2018/19, 2019/20 and 2020/21 use local housing need instead of annual average household growth^{[footnote 1]} for the calculation of the housing requirement. In order to calculate the minimum annual housing need figure using the standard method, DLUHC use the following inputs:

  • The projected average annual household growth over a 10-year period based on 2014-based household projections for all test years - 2018/19, 2019/20 and 2020/21.

  • For the 2018/19 measurement year, adjustment for affordability using the 2017 affordability ratio (affordability ratio for the previous calendar year) published 26 April 2018. For the 2019/20 measurement year, adjustment for affordability using the 2018 affordability ratio published 28 March 2019. For the 2020/21 measurement year, adjustment for affordability using the 2019 affordability ratio published 19 March 2020.

  • An appropriate cap based on the local authority’s plan status on 1 April 2018 for the 2018/19 measurement year, on 1 April 2019 for the 2019/20 measurement year, and on 1 April 2020 for the 2020/21 measurement year (where applicable).

• Local plan information^{[footnote 2]} from both the most recent local plan and the previous local plan. Only local plans that set out an authority’s housing requirement are used^{[footnote 3]}. Data collected includes: the adoption date, start date, end date, housing requirements including trajectories, joint plan requirements, traveller requirements, any unmet need which has been given to or taken from other authorities, and whether the plan has been reviewed and the outcome of this review (see Plan Reviews).

• Current London Plan annual averages 2019-2029^{[footnote 4]} and where relevant, previous London Plan annual borough annual averages 2015-2025^{[footnote 5]}.

• Plan Reviews – In order to determine whether a plan review^{[footnote 6]}, that concludes that policies do not require updating, has been satisfied for the purposes of Housing Delivery Test, the authority must have^{[footnote 7]}

  • Published an assessment of the strategic housing requirement policy (or policies) within 5 years of adoption of such policies; and
  • As part of the review concluded that such policies do not require updating.

In order to reflect the national disruption caused to housing delivery by the pandemic to starts and completions, construction, and monitoring of completions, the period for measuring the homes required in 2020/21 has been reduced by 4 months. A 1-month reduction in the period for measuring the ‘homes required’ in 2019/20 also still applies. As ‘homes required’ data (detailed above) can be calculated by the day, the 2020/21 ‘homes required’ measurement period has been reduced by a total of 122 days, and the 2019/20 measurement was reduced by 31 days.

Given the wide-ranging status and characteristics of local plans across England, the exact process to calculate results varied. The below sets out the steps taken for all authorities and then goes through individual steps taken contingent on the plan status and characteristics which affect the application of the Housing Delivery Test.

For every local planning authority, the following steps were taken:

1. For every local planning authority, the standard method is used (as set out above) in all test years, 2018/19, 2019/20 and 2020/21 respectively.

2. In some cases, local housing need may be negative for one or more of the years being tested. In these instances, all 3 years (including negative values) are summed. If the 3-year summed result is a negative value, this is set to zero. If the sum of the 3 years is positive (despite one or more negative years), the figure is not changed.

3. Net unmet need is calculated for each authority by summing all the need taken (the authority becomes responsible for delivering this housing) and taking away all need given (the authority is no longer responsible for this housing).

4. To convert this into an annual figure, the number of years the plan covers is calculated by taking the difference between the start date of the plan and the end date of the plan, by classifying both the start date and end date as days the plan covers. The total net unmet need figure by authority is then divided by the total plan period.

5. The annual net unmet need for each authority is then added to local housing need in 2018/19, 2019/20 and 2020/21.

In addition to steps 1 to 5, for an authority without an ‘up to date’^{[footnote 8]} local plan, the following steps were taken:

6. The housing requirement is based on the local housing need, plus unmet need figure set out in an adopted plan (as calculated in steps 1 to 5 above) for each year. Since there is no ‘up to date’ local plan, the ‘lower of’ policy does not change the total number of homes required. The exception to this is where the authority is covered by a Spatial Development Strategy (SDS) (see ‘London Boroughs’).

In addition to steps 1 to 5, for an authority with an ‘up to date’ local plan for the entire Housing Delivery Test period, the following steps were taken:

7. The ‘homes required’ figure is based on the annual average from the most recent plan for each year. If the local plan includes a stepped requirement, then the annual average from the stepped requirement corresponding to the relevant period is used.

8. The number of homes required each year is based on the lower of the housing requirement in local plans or local housing need plus unmet need. This is carried out for each of the 3 years.

9. The final number of homes required sums each year’s lower figure to calculate the 3-year total number of homes required.

In addition to steps 1 to 5, for an authority with a plan which is partially ‘up to date’ during the Housing Delivery Test period, the following steps were taken:

10. The ‘homes required’ figure is based on the annual average from the most recent plan for each year. If the local plan includes a stepped requirement, then the annual average from the requirement corresponding to the relevant period is used, and the steps below are applied in the same way.

11. If the plan becomes ‘out of date’ then from this point onwards the housing requirement is based on local housing need plus unmet need depending on the test year.

12. If the plan becomes ‘out of date’ midway through a year, a weighted average for that year is calculated. This means that for as many days that the plan was ‘up to date’ within a test year, the annual average is used. For the remainder of the year, local housing need plus unmet need is used.

13. The number of homes required each year over the 3-year period is based on the lower of the housing requirement or local housing need plus unmet need for each year.

14. In this instance, the housing requirement in a given test year could be:

a. The annual average from the plan (if the plan is ‘up to date’ for the full year).

b. A weighted average of the annual average from the plan and local housing need (for the test years 2018/19, 2019/20 and 2020/21) plus unmet need (if the plan is only ’up to date’ for part of the year).

c. Local housing need plus unmet need, for test year 2018/19, 2019/20 and 2020/21 (if the plan is ‘out of date’ for the full year).

15. For each individual year that the annual target is greater than unmet need, or in the case of 2018/19, 2019/20 and 2020/21 the local housing need plus unmet need, the lower figure is used.

16. The final number of homes required sums each year’s lower figure to calculate the 3-year total number of homes required.

17. Similar to the above, if an authority adopts a plan which covers the latter part of the Housing Delivery Test period (then prior to the period the plan covers), local housing need plus unmet need is used. From the point following the plan start date, the housing target from this is used (using the relevant stepped requirement where appropriate). The ‘lower of’ policy is applied in the same way, comparing the housing requirement in each year to local housing need plus net unmet need.

In addition to steps 1 to 5, for an authority with a previous plan which was ’up to date’ for part of the Housing Delivery Test period and whose current plan was ‘up to date’ for part of the Housing Delivery Test period, the following steps were taken:

18. If the previous plan is ‘up to date’ for part of the Housing Delivery Test period, but the current plan start date encompasses the Housing Delivery Test period that the previous plan covered, the most recent plan is used and the previous plan is not.

19. If the previous plan is ‘up to date’ for part of the Housing Delivery Test period and this period does not overlap with the current plan, then the previous plan is used for as long as it is valid. After this period, the most recent plan is used.

20. If there is a period where there is no plan, then local housing need plus net unmet need is used for this period.

21. Where the periods above do not align with a test year, a weighted average for that year is calculated. This means that, for as many days that the previous plan was ‘up to date’ within a test year, the annual average from that plan is used. For the remainder of the year, either the current plan or local housing need plus unmet need (depending on the status of the current plan) is used.

22. The ‘lower of’ policy for each year is applied based on the housing requirement and local housing need plus net unmet need. The final number of homes required sums each year’s lower figure to calculate the 3-year total number of homes required.

In addition to steps 1 to 5, for a London borough including Development Corporations with full plan making and decision-making powers^{[footnote 9]}, the following steps were taken:

23. London Boroughs are treated the same as other authorities except, where there is no ‘up to date’ plan, the most recent adopted London Plan annual average^{[footnote 10]} is deferred to. In the instance where the London Plan becomes over 5 years old, local housing need would be used as the basis of requirement. If a new London Plan is adopted / published, the new adopted housing requirement will apply from the start of the relevant plan period (as set out in the strategic policies for housing), which may be earlier than the adoption of the strategic policies. If a London Borough has a previous plan that was ‘up to date’ for part of the Housing Delivery Test period, then this plan is used for the period it applies.

24. If the borough plan becomes ‘out of date’ midway through the year, a weighted average for that year is calculated. This means that, for as many days that the plan was ‘up to date’ within a test year, the annual average is used. For the remainder of the year, the annual borough average from the London Plan is used.

25. Similar to step 24, if the borough plan and London plan both become ‘out of date’ part way through the year, the requirement for the remainder of the year is local housing need plus unmet need.

26. If the borough plan includes a stepped requirement, the annual average from the requirement corresponding to the relevant period is used, and the steps above are applied in the same way.

27. The number of homes required each year over the 3-year period is based on the lower of the housing requirement or local housing need plus unmet need in each year.

28. In this instance, the ‘homes required’ figure in a given test year could be one of the following:

a. The annual average from the borough plan (if the plan is ‘up to date’ for the full year).

b. Annual borough average from the ‘up to date’ London Plan (if the borough plan is not ‘up to date’ for the full year).

c. A weighted average of the average from the borough plan and annual borough average from the previous London Plan (if the plan is only ‘up to date’ for part of the year and the previous London Plan is in force for that particular year).

d. A weighted average of the average from the borough plan and annual borough average from the current London Plan (if the plan is only ‘up to date’ for part of the year).

e. A weighted average of the annual average from the previous boroughs plan and the weighted average from the current borough plan (if the previous plan is ‘up to date’ for part of the period, and the current borough plan follows directly from this, or its plan period predates the expiry of the previous plan).

f. A weighted average of the average from the previous borough plan and the annual borough average from the current London Plan (if the previous plan is ‘up to date’ for part of the year and there is no current borough plan to cover the rest of the test year period).

g. A weighted average of the annual borough average from the previous London Plan and the annual borough average from the current London Plan (if the previous London Plan is ‘up to date’ for part of the year and there is no current borough plan to cover the rest of the test year period, but there is an up-to-date London Plan).

h. A weighted average of the annual average from the previous borough plan, the borough average from the current London Plan and the average from the current borough plan (if the previous plan is ‘up to date’ for part of the period, the current borough plan follows indirectly from this meaning the London Plan is relied on in the interim period).

i. A weighted average of the borough average from the previous London Plan and the average from the current borough plan (if the previous London Plan is ‘up to date’ for part of the period, and the current borough plan follows indirectly from this meaning the London Plan is relied on in the interim period).

j. A weighted average of the average from the previous borough plan, the current borough plan, the borough average from the previous London Plan, the current London Plan and then local housing need; if the previous borough plan, current borough plan and all London Plans are all ‘out of date’ for part of the period, then local housing need is relied on to cover the rest of the test period.

29. The final number of homes required is the sum of each year’s lower figure to calculate the 3-year total number of homes required.

30. The London Legacy Development Corporation’s housing requirement is based on its local plan or London Plan annual average in the same way as other London boroughs. Given there is no separately published local housing need, the ‘lower of’ policy is not applied. Therefore, the housing requirement from their local plan is their final number of homes required.

In addition to steps 1 to 5, for authorities covered by a joint plan with a joint requirement, the steps below were taken:

31. Where authorities have an ‘up to date’ joint plan and are being measured jointly for the purpose of the Housing Delivery Test, the housing requirement set out in the joint plan is used.

32. If the joint plan becomes ‘out of date’ during the test period, then a weighted average for the year is calculated; using the joint plan annual average housing requirement up to this point and from then onwards the total local housing need plus net unmet need across all of the component local authorities is used.

33. In all test years 2018/19, 2019/20, and 2020/21, the local housing need figure for joint plan authorities plus net unmet need is used.

34. For each individual year that the joint annual housing requirement is greater than the joint local housing need plus unmet need, the lower figure is used.

35. The final number of homes required sums each year’s lower figure to calculate the 3-year total number of homes required.

In addition to steps 1 to 5, for authorities that have recently reorganised to form new unitary or single-tier authorities, the steps below were taken:

36. Local authorities who formed new authorities (unitary or new lower-tier authorities) can now choose to have their Housing Delivery Test published using their former authority boundaries or their new unitary boundaries for the purpose of the measurement until the fifth anniversary of the new authority’s existence^{[footnote 11]}. Local authorities have the option to choose either approach over this period.

37. To calculate the ‘homes required’ for these areas, steps 1 to 5 (and as appropriate steps 6 to 35) were carried out based on the predecessor authority boundaries. The homes required for the predecessor areas was then added together to produce a ‘homes required’ for the whole of the reorganised authority. Following reorganisation, national statistics are published at the new authority level. However, affordability ratios at predecessor authority levels^{[footnote 12]} were published by the ONS; these were used to calculate Local Housing Need for the test year 2019/20 (as of 1 April 2019) and test year 2020/21 (as of 1 April 2020).

38. The exceptions to the approach set out in paragraph 36, are the unitary authorities of Dorset and Bournemouth, Christchurch & Poole, which have Housing Delivery Test results published using their predecessor authority boundaries. This is because the predecessor authorities of East Dorset and Christchurch have a joint plan with joint plan housing requirement (adopted in April 2014). Straddling the two new unitary areas, this requirement cannot be disaggregated and therefore requirements cannot be attributed to the new authorities. This means that the summing of the predecessor authority requirements, set out in step 36, has not been applied for these authorities.

The housing requirement for travellers:

In addition to steps 1 to 5 and the relevant process depending on local plan status, where applicable the requirement for traveller accommodation^{[footnote 13]} is added to the housing requirement.

This addition takes place prior to the application of the “lower of” policy which compares the housing requirement (containing the travellers housing requirement) and the local housing need plus net unmet need, choosing the lower for each year as the number of homes required for that test year.

The traveller’s housing requirement is calculated through the steps below:

39. The traveller accommodation requirement is based on the traveller’s annual average from the most recent plan for each year. If the local plan contains no traveller’s requirement, then no adjustment is made.

40. Where there is a traveller’s requirement, and the plan becomes no longer ‘up to date’, then from this point onwards the traveller’s adjustment is no longer made.

41. If the plan is no longer ‘up to date’ midway through a year, then for as many days that the plan was ‘up to date’ within a test year, the travellers annual average is used (apportioned based on how many days this was ‘up to date’). For the remainder of the year, no traveller’s housing requirement is added.

42. If the local plan includes a stepped requirement for the traveller’s requirement, then the annual average from the requirement corresponding to the relevant period is used, and the steps above are applied in the same way.

Reducing the requirement for test years 2020/21 and 2019/2020

43. Over the course of the 2020-21 measurement year, there were considerable variations in levels of housing delivery as local authorities and construction industry continued to face disruption on a national, regional, and local level due to the pandemic. As a result, the Government took the decision to apply a 4-month adjustment to the housing requirement figures for 2020-21 in order to account for these fluctuations.

44. For the purposes of the calculation, the ‘homes required’ for the months of April – July 2020 will be deducted from every result. This equates to a deduction of 122 days from the homes required figure for the 2020/21 test year.

45. In line with the decision to reduce the requirement for the test year 2019/2020 because of the COVID-19 National Lockdown in March 2020, all housing requirements that utilise current local or borough plans, the London Plan and/or previous plans were only measured up until the 1st March 2020.The remaining month was discounted from the housing requirement for this test year.

46. Housing requirements that utilise local housing need plus unmet need have been weighted to account for 11 months of 2019/2020 and 8 months of 2020/21.

47. Where the requirement for the test year 2019/20 or 2020/21 is a combination of any number of local plans, borough plans, previous plan and local housing need plus unmet need, the appropriate weighting is applied as per the time of the test year each requirement represents.

Calculating the homes delivered

To calculate the total net homes delivered over the 3-year monitoring period the calculations draw on:

• Net additional dwellings^{[footnote 14]} by local authority district, England 2001-02 to 2020/21^{[footnote 15]}.
• Housing supply: communal accommodation, component flows by local authority district, England 2018/19, 2019/20 and 2020/21 (published as part of the Housing supply; net additional dwellings, England release^{[footnote 16]}).
• Number of students in student only households by the number of bedrooms where all students are aged 18 and over: Office for National Statistics based on 2011 census^{[footnote 17]}.
• Age of Household Reference Person by number of adults in household where all household reference persons are aged 16 and over: Office for National Statistics based on 2011 census^{[footnote 18]}.
• Data supplied to the department by local planning authorities and National Parks about the number of homes within a local planning authority boundary that were delivered in a National Park, 2018/19, 2019/20 and 2020/21; and
• Data supplied to the department by the Greater London Authority about housing completions in the London Legacy Development Corporation that was within different local authority boundaries, Residential Completions between 01/04/2020 and 31/03/2021 by planning authority from London Development Database.

To calculate the homes delivered, the steps taken were:

1. For each local planning authority, net additional dwellings for the test years are used as the starting point. These are then adjusted in several ways.

2. For each authority, estimate the number of net dwellings that would be freed up from the net additional student and other communal accommodation built over the 3-year period. This is calculated by dividing each authority’s student bedrooms annual net change by the national ratio (2.5) and each authority’s other communal bedrooms annual net change by the national ratio (1.8).

3. Adjust the net additional dwellings for each authority by the annual estimate of the number of dwellings which would be required in the absence of the net communal accommodation bedrooms change.

4. For the local planning authorities whose local authority boundaries overlap with a National Park^{[footnote 19]}, either:

a. Remove the net additional homes delivered in the National Park^{[footnote 20]} each year from the net additional dwellings statistics, where the local plan contains a district-specific housing requirement which excludes the National Park area; or

b. If tested against local housing need (when the plan is ‘out of date’ or by virtue of the ‘lower of’ policy), or their local plan has a joint housing requirement with the National Park, do not apply any adjustment to the net additional dwellings statistic for the local authority.

5. For those authorities who have a joint plan with a joint requirement and have chosen to have their Housing Delivery Test calculated jointly, in addition to Steps 1 to 4 above, the ‘homes delivered’ (for the individual local authorities) was summed to provide a delivery total for the whole joint plan area.

6. For the local planning authorities whose boundaries overlap with the London Legacy Development Corporation, for the periods that the local planning authority’s delivery is based on the London Plan, the net homes delivered in the London Legacy Development Corporation are removed from the net additional dwellings statistics based on the data provided to the department by the Greater London Authority.

7. For those authorities who reorganised in April 2019 steps 1 to 3 (and step 4 if appropriate) were followed:

• in years 1 and 2 of the measurement net additional dwellings statistics were published at the predecessor authority boundaries, so these were summed to give delivery for the newly formed authority in these years; and
• in year 3 the net additional dwellings statistics for the new unitary or single-tier authority was used - this was published at the new authority level.

8. For Dorset, and Bournemouth, Christchurch & Poole, the homes delivered was also published at the predecessor authority level (see homes required paragraph 38) meaning:

• For year 1, steps 1 to 3 above were followed, with net additional dwellings not being summed (maintained at former authority levels).
• For years 2 and 3, a separate data collection was provided by the local authorities to DLUHC, which disaggregated the net additional dwellings statistic (published at the unitary boundaries) for the 2019/20 and 2020/21 period; and
• For any joint plans with joint housing requirements at the predecessor authority levels (for example East Dorset and Christchurch; and West Dorset and Weymouth & Portland) Step 5 was followed (i.e., the delivery from the individual predecessor authorities was summed for those joint plan areas).

9. Local authorities who form new authorities (unitary or new lower-tier authorities) can now choose to have their Housing Delivery Test published using their former authority boundaries or their new unitary boundaries for the purpose of the measurement until the fifth anniversary of the new authority’s existence.

10. Borough plans which pre-date the formation of the London Legacy Development Corporation do not give a requirement broken down into dwellings in the borough and dwellings in the London Legacy Development Corporation. However, the London Plan does give separate plan numbers. This means, where the borough’s requirement is based on the London Plan, this will not include the homes to be delivered in the London Legacy Development Corporation. However, when the requirement is based on their own plan, it will include these homes. Therefore, for the adjustment to net additional dwellings, removing those homes delivered in the London Legacy Development Corporation should only be applied for the period where the requirement is based on the London Plan. For these periods, neither the housing requirement nor the net additional dwellings include the homes in the London Legacy Development Corporation.

11. If the borough’s requirement is based on different sources within a test year (for example, the borough plan and then the borough average from the London Plan) then the removal of net additional dwellings each year is scaled to the proportion of the year that the London Plan is relied upon for the housing requirement.

12. The final measure of the homes delivered is the sum of the annual net additional dwellings adjusted for National Park and Development Corporation delivery and the estimated net change in the dwelling stock due to the change in communal accommodation bedrooms.

Calculating the results

The final result for each authority is based on their number of homes required over the 3-year period and the adjusted net additional homes delivered over the same period.

In all cases, the requirement for the number of homes is based on the lower of their annual housing requirement (based on the local plan status and characteristics) the local housing need adjusted for net unmet need (for tests years 2018/19 and onwards). The lower figures in all years are summed to calculate the number of homes required over the total 3-year period for the purpose of the Housing Delivery Test.

However, in order for the 2021 Housing Delivery Test to reflect the disruption caused to housing delivery by the pandemic, the period for measuring the homes required in 2020/21 has been reduced by 4 months. For last year’s 2020 Housing Delivery Test measurement, the period for measuring the homes required in 2019/20 was reduced by 1 month for a similar reason. As ‘homes required’ data (detailed above) can be calculated by the day, the 2020/21 ‘homes required’ measurement period has been reduced by 122 days. The reduced requirement means that each authority’s requirement this year (2021) will be calculated using a 31-month requirement (because of the 5-month COVID-19 adjustment), in contrast to the 36-month requirement used to calculate the 2019 Housing Delivery Test and 35-month requirement used to calculate the 2020 Housing Delivery Test.

The annual net additional dwellings statistic adjusted for National Park and Development Corporation delivery, and the change in communal accommodation bedrooms are summed to calculate the total number of homes delivered over the 3 years for the purpose of the Housing Delivery Test.

Comparing these two totals gives the individual Housing Delivery test for a given authority, joint plan, merged authority or development corporation:

Housing Delivery Test (%) =

Total net homes delivered over 3 year period

divided by

Total number of homes required over 2 year 7 month period

In cases where the total number of homes required is zero (or less), the Housing Delivery Test result is undefined, and no consequences apply.

2. The department collected local plan information from authorities using DELTA webform. In some instances, the information as submitted was adapted for the 2021 Housing Delivery Test measurement and decisions about what information to use were decided on a case-by-case basis. For example, where plans were adopted following the submission of data from local planning authorities, information has been sourced from the published plans. ↩

3. To note, local plan information will be used across all test years, where applicable. For example, local plan information that informs the 2018/19 year may not be applicable for the 2020/21 year if the relevant plan is no longer up to date but may still inform the calculation for the 2018/19 year. ↩

8. An ‘up to date plan’ for the purposes of the Housing Delivery Test is a plan with an adopted housing requirement which is less than 5 years old or is older than 5 years old and has been reviewed and found not to require updating. ‘Out of date’ for the purpose of the Housing Delivery Test, is a plan with an adopted housing requirement which is 5 years old or older and: has not been reviewed or a review has been carried out after the 5-year deadline or a plan review has found that the strategic housing policies require updating. ↩
