How long planning decisions take in Hertsmere
What the public record actually shows for Hertsmere. Every figure below is measured or published, with its sample and its date. Nothing here is an estimate, and none of it predicts what a particular application will do.
How long decisions took
Median weeks from validation to decision, counted from the council’s own register. A median means half of decisions took longer, so it is a middle, not a target.
| Application type | Median | Decisions counted |
|---|---|---|
| Small residential | 16.1 weeks | 66 |
| All other applications | 8 weeks | 140 |
Measured over applications decided 1 July 2024 to 13 July 2026.
Housing Delivery Test
Hertsmere measured 26% in the 2025 Housing Delivery Test — consequence: Presumption.
MHCLG records 567 homes delivered against a three-year requirement of 2,181.
It fell well short of its housing requirement. Under the August 2026 Framework that is one of the routes into policy S5(1)(j), which can support housing meeting an evidenced unmet need outside a settlement, subject to that policy’s own tests. It is a point in your favour, not a decision.
Published by MHCLG on 17 August 2026. This is the most recent measurement published, not a current-year figure.
Planning appeals in Hertsmere
49 allowed in full, 48 dismissed, from 97 planning appeals decided for Hertsmere between 1 January 2021 and 31 July 2026.
We do not turn that into a percentage: under 100 decided appeals, a rate looks like a finding and behaves like noise. The counts are the honest form. This is not a statement that no appeals succeeded. Only refused applications get appealed, so these are a self-selected minority of decisions.
What this page is not
It does not tell you what constrains a particular site in Hertsmere. Designations sit on land, not on councils. For that, run a free check on the site itself: it names every designation on or beside the boundary, states when each dataset was last collected, and says plainly where a record is not published rather than showing you a clear result.
