Summary of Errors Found

2021 Missing Breakdown: The data provided the Total number of individuals Added (205) and the Part 1/Part 2 End of Period split (45 and 160 respectively), but did not explicitly list the 'Added' or 'Start' numbers for the subgroups. Since the previous year (2020) ended with 0 entries, the 'Added' figures were derived directly from the 'End of Period' figures.
2022 Missing Breakdown: The data provided the End of Period split for Part 1 (79) and Part 2 (236) but did not provide the 'Start of Period' or 'Added' breakdown. These were derived by comparing the 2022 End figures with the 2021 End figures.

Summary of Corrections

2021 Individuals: Derived part_1_individuals_added (45) and part_2_individuals_added (160) to align with the provided End of Period totals.
2022 Individuals: Derived part_1_individuals_added (34) and part_2_individuals_added (76) by calculating the difference between the 2022 End totals and the 2021 End totals.

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 Dorset's annual returns published by the Department for Levelling Up, Housing and Communities (DLUHC), Freedom of Information requests, and published council documents. We cross-reference multiple sources to verify accuracy and flag any inconsistencies. If you spot an error, please let us know.
