The Busiest Planning Departments in England and Wales

Published 12 March 2026

Some planning departments are processing thousands of applications while others handle just a few hundred. We've ranked the busiest councils by total application volume to show where planning teams are under the most pressure, and what that means if you're submitting an application in one of these areas.

The 15 Busiest Planning Authorities

1. Herefordshire - 38,811 applications
2. Cornwall - 7,858
3. Richmond - 6,286
4. West Northamptonshire - 5,811
5. Leeds - 5,523
6. Birmingham - 5,381
7. Bromley - 5,300
8. Dorset - 5,281
9. Wiltshire - 5,068
10. Bristol - 4,122
11. Charnwood - 3,891
12. Harrogate - 3,856
13. Westminster - 3,745
14. BCP (Bournemouth, Christchurch and Poole) - 3,705
15. Oxford - 3,358

Why Herefordshire Is So Far Ahead

The first thing you'll notice is that Herefordshire's figure dwarfs everyone else. At nearly 39,000 applications, it handles five times more than second-placed Cornwall. This is partly a data artefact of our collection method (Herefordshire's portal includes historical records going back further than most), but it also reflects the reality of a large rural authority with extensive agricultural, equestrian, and residential development activity spread across a huge geographic area.

The Unitary Council Effect

Several councils on this list exist in their current form because of local government restructuring. West Northamptonshire was created in 2021 by merging Daventry, Northampton, and South Northamptonshire. Dorset merged five district councils. BCP combined Bournemouth, Christchurch, and Poole.

These mergers consolidate application volumes under a single authority, which makes the numbers look higher than they would have been for any of the predecessor councils. But the workload is real. The planning teams that inherited these combined caseloads were not always given proportionally larger budgets or more staff. Some of the delays applicants experience in these areas trace directly back to a restructuring that was supposed to create efficiency but sometimes created strain.

Rural vs Urban: A Surprising Split

You might expect the busiest planning departments to be in major cities. In reality, it's a mix. Cornwall, Herefordshire, Dorset, and Wiltshire are large rural authorities where geographic area, rather than population density, drives volume. Agricultural buildings, barn conversions, farm diversification schemes, equestrian facilities, and rural housing generate significant application numbers.

Rural applications also tend to be more complex than urban ones. A new dwelling in a village might require a flood risk assessment, ecology survey, landscape impact assessment, highways statement, and drainage strategy. An equivalent householder application in a city might need only a basic set of drawings. More documents mean more work for planning officers, even if the number of applications is the same.

What High Volume Means for You

If your council is on this list, expect the following:

Longer Processing Times

The government's target is 8 weeks for minor and householder applications, and 13 weeks for major ones. Busy councils regularly miss these targets. When a planning officer has 80 live cases on their desk instead of the recommended 40-50, something has to give. Typically, it's the speed of assessment rather than the quality, but both can suffer.

Less Personal Attention

In a quieter council, your planning officer might visit the site proactively, phone you to discuss concerns, and negotiate amendments informally. In a busy department, you're more likely to receive a standard consultation letter and a decision notice with minimal dialogue in between. Your application is one of thousands, so it needs to speak for itself.

Stricter Validation

Overloaded teams have less patience for incomplete submissions. If your application is missing a document, it will be rejected at validation rather than progressed with a request for additional information. This is actually a good thing from the council's perspective, because it keeps the live caseload manageable, but it means more work upfront for you.

More Experienced Officers

The silver lining is that busy departments tend to have well-oiled processes and experienced officers. An officer who has assessed 500 householder extensions knows exactly what works and what doesn't, and their advice (when you can get it) tends to be practical and reliable.

Volume and Approval Rates: Is There a Link?

You might expect busy councils to approve less because they're under pressure and taking shortcuts, or to approve more because their officers are experienced and pragmatic. The truth is that volume and approval rate have a surprisingly weak relationship. Some high-volume councils like Richmond have above-average approval rates, while others like Leeds are close to the national average.

The bigger driver of approval rates is not how busy the council is, but what constraints apply to the land and how ambitious the applications are.

Seasonal Patterns in Applications

Planning application volumes are not consistent throughout the year. Most councils see a spike in submissions in January and February (people making New Year plans for building work), a dip over the summer holidays, and another surge in early autumn. If you can, submitting in a quieter month like July or August may get your application onto an officer's desk faster, simply because there's less competition.

Tips for Busy Council Areas

• Submit complete applications. Missing documents cause delays in already stretched departments. Use the council's validation checklist and double-check every item before you submit.
• Consider pre-application advice. In a busy council, a pre-app meeting is one of the few ways to get personal attention from a planning officer before your application enters the system.
• Be patient but proactive. If your target date passes, a polite follow-up email to the case officer is reasonable. Planning officers in busy departments juggle competing demands, and a reminder that your application exists can sometimes move things along.
• Use a planning agent or architect who knows the council. Local professionals often have established relationships with officers and know the informal expectations that are not written in policy documents.
• Don't assume silence means progress. If you haven't heard anything four weeks after submission, check the council's online portal to confirm your application has been validated and a case officer assigned.
