Summary of Errors Found

No arithmetic inconsistencies were found in the provided 'Total' counts across the dataset. The flow of data from year to year (2016 through 2023) is mathematically perfect for both individuals and groups.

Summary of Corrections

Derived Part 1 / Part 2 Split (All Years): The specific breakdowns for Part 1 and Part 2 were missing. Since the local_connection_test was either null or false for every year, it was derived that all entrants belong to Part 1 of the register. Consequently, all Part 1 values were adjusted to match the Totals, and all Part 2 values were set to 0.
2019 Groups: The total_groups_added field was missing (null). It was derived as 0 to maintain consistency between the 2018 end count (2) and the 2019 end count (2).

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 Mendip'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.
