Five-year supply addendum (February2025)
This addendum sets out the five-year supply calculation for Blackpool following the publication of the revised National Planning Policy Framework (NPPF) in December 2024.
This addendum uses housing supply and completion data from the Five Year Housing Land Supply 2024 (base date 01 April 2024) and applies the Local Housing Need (LHN) requirement in accordance with the revised NPPF. A full update of the five-year housing land supply document using data to the 31 March 2025 will be published in spring/summer 2025.
Paragraph 79 of the revised NPPF reintroduced the requirement to include a ‘buffer’ to the five-year supply of housing. The level of buffer required is linked to the Housing Delivery Test (HDT). Results of the HDT are published annually by government. The most recent HDT results were published in December 2024 and indicate that Blackpool passes the test. As such a 5% buffer is required to be added to the five-year housing land supply. Figure 1 sets out the calculation used to determine the five-year requirement.
Figure 1: Annual requirement calculation
Calculation of the five year requirement
| Calculation of the five-year requirement |
|---|
| Local Housing Need (LHN) annual requirement = 585 dwellings per annum. |
| Additional 5% buffer = 146 |
| Five-year requirement (585 x 5) + 146 = 3071 dwellings (614 dwellings per annum) |
Figure 2: Summary of supply of sites included within five-year calculation
| Source of supply | Number of dwellings |
|---|
| New build sites that do not involve major development and have outline planning permission and sites with detailed planning permission |
659 |
| Major conversions and changes of use with detailed planning permission |
92 |
| Source of supply | Number of dwellings |
|---|
| Minor conversions and changes of use with detailed planning permission |
67 |
| Windfall allowance for minor conversions and changes of use (490 minus 67 dwellings with permission) |
423 |
| Other deliverable sites |
367 |
| Total |
1608 |
Figure 2 provides a summary of the supply of sites which are included within the five-year supply calculation and details how the ‘net deliverable capacity’ is calculated. This uses the information set out within the Five Year Housing Land Supply 2024 paper.
The five-year supply position for Blackpool is as follows:

The current five-year supply position for Blackpool is as follows:
|
| Net deliverable capacity in five-year period ÷ annual requirement = 1608 ÷ 614 |
| Blackpool housing supply = 2.62 years |
The calculation demonstrates that there is not currently a five-year supply of housing land in Blackpool against the target established by local housing need. All the data for sites contained within the five-year supply can be found within the appendices to the Five Year Housing Land Supply 2024.
