Planning appeal success rates by council, dwelling size, and housing delivery (2021- Oct 2026)
Explore planning appeal outcomes across the UK's local authorities* by dwelling size, including where councils are missing their housing delivery targets & where the new NPPF is making an impact.
The new NPPF came into force on 17 August 2026. This report uses Searchland's planning and appeal data to show how appeals for major housing schemes were decided before and since that date, council by council. Understand where planning appeals are being approved the most, which councils aren't meeting their housing delivery targets and how policy is making an impact.
Whether you're weighing up an appeal on a refused scheme, assessing risk on a site or advising a client, it shows where appeals succeed, how that varies by dwelling size, and which councils are falling short of target.
Why is the data important?
Clarity on planning risk
A planning application's outcome doesn't always end with the council's initial decision. Appeals play a critical role in unlocking development potential - but success rates vary widely between councils.
This report goes beyond headline refusal rates to highlight where appeals are most likely to succeed, giving developers, planners, and land promoters an edge in site selection, strategy, and risk assessment.
By combining planning application records, appeal outcomes, and dwelling size analysis, we provide a clear picture of how local authorities perform at appeal - and where applicants are most likely to overturn refusals.
This isn't just a dataset - it's a strategic map of where planning barriers are being successfully challenged.
