When Hertsmere Borough Council refuses an application, or does not decide it in time, the applicant can appeal to the Planning Inspectorate. An appeal that is allowed is one the council lost. Raw rates are not comparable between councils, because some kinds of appeal are allowed far more often than others, so the Inspectorate's national rate for each kind is applied to this council's own caseload to give the rate its mix predicts.
Hertsmere Borough Council, raw rate

of judged appeals were allowed, so the council's decision did not stand
Expected for this mix of appeals
30.9%
what the national rate for each kind of appeal predicts for this council's caseload
7.5 percentage points above expected. Hertsmere Borough Council's decisions are overturned more often than the national record for the same kinds of appeal predicts for its caseload.
512 appeals counted, 492 judged either way (189 allowed, 303 dismissed), 20 judged neither way. These are appeals decided 2016-07 to 2026-06.
Each kind of appeal against the national rate for the same kind. This is the comparison the headline is built from.

“Judged” counts appeals allowed or dismissed. The rest were withdrawn, invalid, split or unrecorded, and are counted but never treated as appeals the council won. A percentage is published only where at least 5 appeals were judged either way. Where it is not, the counts still are: a rate over one or two cases would claim a precision the sample cannot carry.

Developers pay into planning obligations and the Community Infrastructure Levy at Hertsmere Borough Council, each sum tied to a purpose written into the agreement. The council's own register records what has been collected, what has been spent and what is left.
That figure is the register's own Available column, reproduced rather than recalculated. It is money the council has banked against a purpose written into a signed agreement and has not paid out. It is not money the council is free to spend on something else, and it is not a sum any reader can apply for. Councils differ in whether they also deduct money already earmarked to a specific project, so read it against the Spent and Allocated columns on the register itself rather than as a single national measure.

Figures are the whole of each register as published on that date, not a recent period. Our collected totals match each register’s own published total exactly. Purposes are grouped from the council's own covenant wording, which differs between authorities. Wording that is specific to this council, such as the name of a local fund, is grouped under other local categories.
Beside what the council collected from developers, this is what central government confirmed: schemes in the area with grant agreed under the Homes England Affordable Homes Programme 2021 to 2026.

Contains public sector information licensed under the Open Government Licence v3.0. Figures are as at 31 March 2025, the publication's own cut-off, so later schemes are not in them. Grant requested is the publisher's own figure at the point grant was confirmed, not money drawn down. Schemes are placed by the local authority name in the publication, which carries no planning reference.
Hertsmere Borough Council is a local planning authority responsible for processing planning applications within its area. Applications are submitted through the council's planning portal and cover a wide range of development types, from householder extensions and change of use to large-scale residential and commercial schemes.
SiteLens tracks the Hertsmere Borough Council planning register daily and enriches every new application automatically. Each is AI-classified by category and trade, given an estimated value band and a plain-English project brief, mapped, and checked against constraint flags like flood zones, conservation areas and green belt. Where an application names an agent, SiteLens shows the firm and matches companies to Companies House. Pro adds the applicant's name, the directors and company health behind each match, and the agent's direct email and phone where the council or firm publishes them, so you know who to speak to about the scheme.
You can also browse the council's own planning register on the official Hertsmere Borough Council planning portal.
