The Hardest Councils to Get Planning Permission in the UK

Published 8 March 2026

Not all councils are created equal when it comes to planning permission. While the national average approval rate sits around 85-90%, some authorities refuse a strikingly high proportion of applications. If you're planning a project in one of these areas, you'll want to be especially well-prepared, because the margin for error is razor-thin.

The 10 Toughest Councils for Planning Permission

1. New Forest (District) - 40.2% approval rate (483 decided applications)
2. Chiltern South Bucks - 41.9% (444 decided)
3. Glasgow - 42.7% (782 decided)
4. Conwy - 56.1% (228 decided)
5. Waltham Forest - 56.5% (248 decided)
6. Epping Forest - 58.2% (634 decided)
7. Buckinghamshire - 58.2% (299 decided)
8. Leicester - 58.5% (253 decided)
9. Liverpool - 59.0% (305 decided)
10. Rushcliffe - 59.4% (202 decided)

Think about what that New Forest figure means in practice. For every ten applications submitted, six are refused. That's six sets of architect's fees, application fees, and months of waiting, all for nothing.

Why These Councils Refuse More

The pattern is revealing. Many of the toughest councils share common characteristics, and understanding them can help you avoid becoming a statistic.

Environmental Constraints

New Forest, Epping Forest, and Chiltern South Bucks are all heavily constrained by national parks, areas of outstanding natural beauty (AONBs), or green belt. These designations impose stricter planning policies that make approval harder.

In the New Forest, for example, the National Park Authority acts as the planning authority, not the district council. National park planning policies prioritise landscape conservation over development, and the bar for design quality is significantly higher. Even householder extensions face scrutiny over materials, scale, and visual impact that would be unusual elsewhere.

Epping Forest sits within the Metropolitan Green Belt, where there is a strong presumption against development that would harm openness. Many applications in this area are for projects that simply cannot overcome this policy hurdle, no matter how well-designed they are.

Conservation-Heavy Areas

Buckinghamshire and Rushcliffe contain significant numbers of conservation areas where permitted development rights are restricted and design standards are higher. In a conservation area, what might be a perfectly acceptable extension in a neighbouring street can be refused because it doesn't preserve or enhance the character of the area.

The challenge is that "character" is inherently subjective. What one planning officer considers sympathetic design, another might see as pastiche. This subjectivity, combined with strict policy, creates uncertainty for applicants.

Urban Pressure

Glasgow, Waltham Forest, Liverpool, and Leicester face intense development pressure in urban settings where neighbour impact, parking, and density concerns drive more refusals. In dense urban areas, almost every development affects someone nearby. An extension that blocks a neighbour's light, a conversion that removes parking, or a new dwelling that overlooks a garden can all trigger objections and, ultimately, refusal.

Glasgow's position in the top three is particularly notable. Scotland's planning system has its own distinct policies, and Glasgow's combination of tenement conservation, urban density, and a busy planning department creates a challenging environment for applicants.

What Happens When You Get Refused?

A refusal is not the end of the road, but it is an expensive detour. You have three main options:

• Redesign and resubmit. This is the most common approach. You address the reasons for refusal, amend your plans, and submit a fresh application. The good news: if you resubmit within 12 months, you don't pay the application fee again for a similar scheme.
• Appeal to the Planning Inspectorate. You can appeal a refusal, and a government-appointed inspector will make an independent decision. Appeals are free to submit but typically take 6-12 months, and nationally, only about a third of appeals succeed. In highly constrained areas like the New Forest, appeal success rates are even lower.
• Negotiate with the council. Sometimes a phone call to the case officer after refusal reveals that a modest change to the scheme would make it acceptable. This informal route is often quicker than a formal resubmission.

Refusal Rates Vary by Application Type

The headline approval rate for a council hides significant variation. Householder applications (extensions, loft conversions) are typically approved at higher rates than full planning applications for new dwellings. In a tough council, you might see a 75% approval rate for householder work but a 35% rate for full applications.

This matters because the experience of a homeowner applying for a kitchen extension is very different from a developer proposing three new houses on a garden plot. If your project is a straightforward domestic extension, the council's overall refusal rate may overstate the risk you face.

The Real Cost of Getting It Wrong

A refused application is not just a bureaucratic inconvenience. The typical costs include:

• Architect/designer fees: £2,000-£5,000 for detailed drawings that may need to be substantially reworked
• Application fee: £258 for householder (refunded on free resubmission within 12 months, but not if you change the scheme significantly)
• Specialist reports: tree surveys, ecology assessments, heritage statements, and flood risk assessments can cost £500-£2,000 each
• Time: three to six months wasted, sometimes longer if you need to appeal

What You Can Do in Tough Council Areas

If your project is in a high-refusal area, preparation is everything:

• Get pre-application advice. Most councils offer this, and it is invaluable in high-refusal areas. You'll get an officer's honest view on whether your scheme has any chance before you spend money on full drawings.
• Hire a local architect. Someone who knows the council's preferences, has worked with their officers before, and understands the design expectations of the area. A generic design that might work in a permissive borough can be a death sentence in a constrained one.
• Study recent decisions. Look at what has been approved and refused near your site. This is genuine intelligence. If a similar extension was refused two doors down last year, you need to know why before you submit yours.
• Don't over-develop. In constrained areas, modest, well-designed schemes win. Trying to squeeze the maximum possible floor space out of a site is the fastest route to refusal.
• Front-load the paperwork. In tough councils, incomplete applications are not just delayed. They can be refused outright. Submit every supporting document the council could possibly want.
