Summary of Errors Found
- 2017 Individuals Mismatch: The reported end count was 91, but start (32) + added (61) = 93. Trusted the "Added" count and corrected end of period to 93.
- 2018 Individuals Mismatch: The reported end count was 123, but start (93) + added (32) = 125. Trusted the "Added" count and corrected end of period to 125.
- 2019 Individuals Mismatch: The reported end count was 183, but start (125) + added (57) = 182. Trusted the "Added" count and corrected end of period to 182.
- 2020 Individuals Mismatch: The reported end count was 242, but start (182) + added (39) = 221. Trusted the "Added" count and corrected end of period to 221.
- 2021 Data Gap (Individuals): There was a large drop in numbers (End 152 vs Start 221 + Added 39). Derived 108 removals to reconcile the data, as no removals were reported.
- 2021 Data Gap (Groups): Groups dropped from 2 to 0 with no removals reported. Derived 2 removals.
- 2022 Individuals Inconsistency: Calculated end would be 195 (152 Start + 43 Added), but reported end was 203. Since 2023 Start is also reported as 203, adjusted 2022 "Added" from 43 to 51 to align with higher registration numbers and maintain consistency with 2023.
- 2022 Groups Inconsistency: Started with 0, ended with 1, but "Added" was 0. Adjusted "Added" to 1.
- 2024 Start of Period (Individuals): Reported start was 261, but 2023 ended with 274. Adjusted start to 274 to maintain flow. Consequently, adjusted 2024 End to 173 (Start 274 + Added 50 - Removed 151).
- 2024 Groups Inconsistency: Reported start was 2, but 2023 ended with 1. Adjusted Start to 1. Since reported End is 2, derived 1 group added (reported 0).

Frequently asked questions
Understanding self-build registers and local authority duties.
Under the Self-build and Custom Housebuilding Act 2015, all local authorities in England must maintain a register of individuals and groups who want to build their own homes. The register helps councils understand demand for self-build plots in their area and plan accordingly.
Part 1 includes everyone who meets the basic eligibility criteria (over 18, seeking to acquire land in the area, and a British citizen/EU national with right to reside). Local authorities have a legal duty to grant enough permissions to meet Part 1 demand. Part 2 is optional and councils can apply additional local eligibility tests—such as local connection requirements—to filter applicants. While Part 2 numbers still represent real demand, there's no specific legal duty attached to meeting it.
A base period runs from 31 October to 30 October the following year. The first base period began on 1 April 2016 (when the duty came into force) and ended on 30 October 2016. Councils must count how many people joined Part 1 during each base period, then grant enough "suitable" permissions within 3 years of the end of that base period.
For each base period, we compare the Part 1 demand (registrations) against suitable permissions granted within the 3-year compliance window. If permissions fall short of demand for any base period, that shortfall becomes an outstanding deficit. Importantly, surplus permissions from one period cannot be carried forward to offset deficits from later periods—each base period must be addressed independently.
The legislation refers to granting permissions for "suitable serviced plots of land"—meaning sites with access to connections for electricity, water, and sewerage (or can be provided in a reasonable time). Councils can count permissions they've granted directly, as well as those granted on appeal or through permitted development. The permission doesn't have to be for a council-owned site.
Councils must: (1) maintain the register and allow eligible people to join, (2) have regard to the register when carrying out planning and housing functions, and (3) grant enough suitable permissions to meet the Part 1 demand from each base period within 3 years.
