When Three Rivers District 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.
Three Rivers District Council, raw rate
31.2%
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
0.3 percentage points above expected. Three Rivers District Council's decisions are overturned more often than the national record for the same kinds of appeal predicts for its caseload.
546 appeals counted, 529 judged either way (165 allowed, 364 dismissed), 17 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.
| Appeal type | Cases | Judged | Allowed | This council | National |

| Planning Appeal | 238 | 232 | 76 | 32.8% | 28.8% |

| Listed Building Consent & Conservation Area Consent Appeal | 11 | 9 | 2 | 22.2% | 25% |
| Lawful Development Certificate | 8 | 8 | 1 | 12.5% | 36.9% |
| Tree Preservation Order | 8 | 7 | 2 | 28.6% | 20.6% |

“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 The rest were withdrawn, invalid, split or unrecorded, and are counted but never treated as appeals the council won.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.

Three Rivers District Council collects contributions from developers under planning obligations, but we do not yet hold its register in a form we can publish figures from. Only a minority of authorities publish one we can read, and this is not one of them, so we show nothing rather than a figure we cannot stand behind.
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.
Three Rivers District 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 Three Rivers District 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 Three Rivers District Council planning portal.
