OriginalAI Adjusted
Summary of Errors Found
- Missing Part 1/Part 2 Breakdowns (All Years): The original data did not split figures between Part 1 and Part 2. As
local_connection_testwas consistentlyfalse(or implied false in earlier years), all individuals and groups were assigned to Part 1, and Part 2 was set to 0. - 2018 Individual Totals Discrepancy: The reported Total Individuals End of Period (363) did not match the calculated flow: Start (236) + Added (118) = 354. The figure was corrected to 354 to ensure mathematical consistency with the added figures.
- 2019-2022 Cumulative Count Discrepancy: From 2019 onwards, the reported 'Total Individuals End of Period' figures dropped significantly (e.g., from 354 down to 223 in 2019) without any corresponding 'Removed' data to explain the decrease. To prioritize the 'Added' numbers and provide an accurate cumulative total, the Start and End totals for 2019, 2020, 2021, and 2022 were recalculated derived from the previous year's balance plus additions.
- 2024 Group Totals Discrepancy: The 2024 data reported 0 groups for both Start and End of period, despite the register ending with 2 groups in 2023. These were corrected to 2 to maintain the historic record.

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.
This data comes from Wiltshire's annual returns published by the Department for Levelling Up, Housing and Communities (DLUHC), Freedom of Information requests, and published council documents.
