The UK's Most Permissive Planning Authorities in 2026

Published 4 March 2026

If you're planning a building project, the council you live in can make a significant difference to your chances of getting planning permission. We've analysed over 500,000 planning applications across the UK to identify the councils with the highest approval rates, and the results reveal some fascinating patterns about how the planning system actually works on the ground.

The Top 10 Most Permissive Councils

Based on our data covering applications with a recorded decision, here are the UK councils most likely to approve your planning application:

1. Havering - 99.7% approval rate (300 decided applications)
2. Eastbourne - 99.3% (272 decided)
3. Lisburn and Castlereagh - 99.0% (295 decided)
4. Shetland Islands - 98.6% (285 decided)
5. City of London - 98.5% (1,458 decided)
6. Fareham - 98.4% (497 decided)
7. South Ayrshire - 98.3% (300 decided)
8. Mid Ulster - 98.1% (269 decided)
9. North Lanarkshire - 98.1% (1,654 decided)
10. Copeland - 98.1% (159 decided)

The national average approval rate sits around 85-90%, so these councils are approving at rates 10-15 percentage points higher than the norm. That gap might not sound dramatic, but in a system where refusal can cost you thousands in wasted fees and architectural drawings, it matters.

Why Do These Councils Approve So Much?

High approval rates don't necessarily mean these councils are rubber-stamping everything. Several factors can push approval rates higher without lowering standards.

Strong Pre-Application Services

Councils like Fareham and Havering invest heavily in pre-application advice. When a planning officer tells you before you submit that your two-storey extension won't fly but a single-storey one will, you adjust your plans accordingly. The result: fewer hopeless applications enter the system, and approval rates climb. This is arguably the planning system working well, not poorly.

Less Constrained Land

Areas like Copeland in West Cumbria and the Shetland Islands have relatively few conservation areas, minimal green belt, and limited heritage designations. When there are fewer policy reasons to refuse, more applications get through. Compare this with somewhere like the Cotswolds or the Peak District, where almost every development triggers heritage, landscape, or ecology concerns.

Application Mix

The types of applications a council receives heavily influence its overall approval rate. Councils that handle a high proportion of householder applications (extensions, loft conversions, garden rooms) tend to have higher approval rates because these smaller projects are inherently less controversial. A council dominated by large-scale housing applications on greenfield sites will naturally refuse more.

Political and Cultural Factors

Planning committees are made up of elected councillors, and the political culture of a council influences how officers and members approach development. Some councils have an explicitly pro-growth stance. Others prioritise preservation. Neither approach is wrong, but the difference shows up clearly in the numbers.

Northern Ireland Stands Out

Several Northern Irish councils appear in the top 15. Lisburn and Castlereagh, Mid Ulster, Derry and Strabane, and Causeway Coast and Glens all exceed 97%. This likely reflects the separate planning system in Northern Ireland, which was devolved to councils in 2015 after decades of centralised control by the Department of the Environment.

The relatively recent handover means many NI councils are still building up their planning teams and developing local policies. In practice, this can mean a more collaborative approach between officers and applicants, with a focus on finding ways to approve rather than reasons to refuse.

Scotland's Quiet Success

South Ayrshire and North Lanarkshire both feature in the top 10, and they are not alone. Several Scottish councils sit comfortably above 95%. Scotland operates under a different planning framework (the Town and Country Planning (Scotland) Act 1997), with its own national planning framework and distinct policies on housing land supply. The Scottish system's emphasis on "placemaking" and early engagement may contribute to smoother outcomes.

Does High Approval Mean Fast Decisions?

Not necessarily. Approval rate and decision speed are two different measures. A council might approve 99% of applications but take 16 weeks to do it. Conversely, a tough council might refuse quickly. That said, there is a loose correlation: councils with strong pre-application services tend to validate applications faster because fewer come in incomplete or fundamentally problematic.

If speed matters to you as much as outcome, check the council's average decision time on Planning Signal's council pages alongside the approval rate.

Should You Relax If You're in a Permissive Area?

Absolutely not. Even in a council with a 99% approval rate, that remaining 1% represents real applications that were refused. And refusal costs real money: architect fees for drawings you can't use, application fees that are not refunded, and months of delay while you redesign and resubmit.

High approval rates can also breed complacency. Applicants in permissive areas sometimes skip pre-application advice or submit poorly thought-out designs, assuming the council will approve regardless. The councils on this list approve at high rates partly because applicants submit good work, not in spite of submitting poor work.

A Note on the Data

These figures are based on applications where a clear decision (approved, conditionally approved, permitted, refused, or rejected) has been recorded. Withdrawn applications are excluded. Councils with fewer than 100 decided applications are not included to ensure statistical reliability.
