What is Planning Permission?

Summary

Planning permission isn’t a formality or a guessing game. It’s a structured judgement about impact, policy, and risk – and after submitting over 100 planning applications in the past two years alone, one thing is clear: outcomes become predictable when planning is treated as a strategic process rather than an administrative step.

why do you need planning permission

Planning Permission Is Not What Most People Think It Is

Planning permission is one of the most misunderstood elements of the UK property system. It is often described as a simple hurdle: something you either need or don’t need, something you submit and wait for, something that is approved or refused. That framing is not just misleading – it actively causes problems. In reality, planning permission is not a formality and it is not a box-ticking exercise. It is a decision-making framework used by local authorities to assess whether a proposal is acceptable in its specific context, when judged against planning policy and its impact on others. Once this is properly understood, planning stops feeling arbitrary and starts behaving in a far more predictable way. Having been involved in the submission of over one hundred planning applications in the past two years alone, across a wide range of residential and commercial projects, we see patterns emerge very quickly. Planning decisions are rarely random. When schemes succeed, it is usually for clear, identifiable reasons. When they fail, the causes are almost always visible in hindsight.

What Planning Permission Really Assesses

At its core, planning permission is the council answering a single question: whether a proposal is acceptable in its location, given its consequences. It is not approval of an idea in isolation. It is a judgement about impact. This distinction explains why two extensions of similar size can receive entirely different outcomes, and why a proposal that feels reasonable to a homeowner can still be refused. Planning does not assess effort, cost, or personal need. It assesses how a development affects neighbouring properties, the character of an area, safety, amenity, and compliance with adopted policy. Once this is understood, the apparent unpredictability of planning decisions largely disappears. Officers are not deciding whether they like a proposal. They are deciding whether they can defend it.

Why the Planning System Exists – and Why That Shapes Every Decision

The planning system exists to balance private ambition with public interest. Every application is assessed not only on what it provides to the applicant, but on what it takes from others. Loss of light, loss of privacy, overbearing massing, changes to character, and impacts on highways or access are all central considerations. In practice, refusals rarely occur because development is inherently unacceptable. They occur because the harm created by a proposal has not been properly controlled, acknowledged, or justified. Across a high volume of recent applications, one principle is consistent: where harm is identified and addressed through design and reasoning, approval routes open. Where harm is ignored or dismissed, refusal becomes the only defensible outcome.

When Planning Permission Is Required – and Why Context Matters More Than Labels

One of the most common misconceptions is that planning permission is determined by the type of work being proposed. In reality, context governs everything. Two rear extensions of identical depth can produce completely different outcomes depending on boundary relationships, existing additions, neighbouring window positions, plot rhythm, or local character. This is why generic online advice so often fails homeowners. It cannot account for site-specific judgement. The more useful question is not whether planning permission is required in theory, but what planning judgement a proposal will trigger in practice. That is where experience matters.

Permitted Development: A Useful Right That Is Frequently Misunderstood

Permitted development is often presented as a way to bypass the planning system altogether. In practice, it is one of the most misunderstood parts of it. While permitted development rights allow certain works to proceed without a formal application, they are conditional and highly sensitive to planning history and context. Across dozens of recent householder projects, the most common failures arise from assumption rather than fact. Previous extensions erode allowances. Conditions remove rights entirely. Designs that technically comply still generate serious neighbour conflict. Even where planning permission is not required, planning consequences remain. Enforcement action, neighbour disputes, and complications during resale are common outcomes of poorly judged permitted development schemes. Permitted development removes the application, not the responsibility.

Who Actually Makes Planning Decisions

Most planning applications are determined by planning officers rather than councillors. Their role is to assess proposals against national and local policy, taking account of material planning considerations. Neighbour comments are considered only where they raise legitimate planning issues. The number of objections carries far less weight than whether those objections identify genuine planning harm. In practice, schemes are approved every week despite strong opposition where the planning case is sound, and refused where it is not. Across a large number of submissions, a clear pattern emerges. Planning officers are not looking for perfection. They are looking for clarity. When a proposal explains its reasoning, acknowledges its impacts, and demonstrates how those impacts are controlled or justified, decisions become far less opaque.

Why Planning Applications Really Get Refused

Refusals are often perceived as subjective or political. In reality, they are usually predictable. In most cases, refusal occurs because a proposal leaves the planning officer without a defensible route to approval. Overlooking impacts are unresolved. Massing disrupts established character. Justification asserts rather than demonstrates. These are not matters of taste. They are matters of planning judgement. Importantly, many refused schemes are not unacceptable in principle. They are unresolved. In our experience, refusal is often formalised feedback – but only for those prepared to respond strategically rather than defensively.

What Experience Reveals About Successful Planning Outcomes

One of the clearest lessons from repeated exposure to planning decisions is that optimism is not a strategy. Schemes that perform well tend to be those where scale is shaped by context rather than ambition, where impact is acknowledged rather than denied, and where design decisions are explained rather than assumed. Projects that struggle are often those where the first submission is treated as a test run. The planning system does not reward trial and error. It rewards judgement.

A More Accurate Way to Think About Planning Permission

Planning permission is not about drawings, and it is not about luck. It is about managing risk early enough that approval becomes the logical outcome. When planning is treated as a strategic exercise rather than an administrative task, it stops being a barrier and starts acting as a filter – one that protects investment, reduces conflict, and brings clarity to complex decisions. Planning permission is not something you simply obtain. It is something you design for. Approached with clarity, restraint, and understanding, it becomes a powerful tool rather than an obstacle – one that brings certainty where decisions matter and structure where projects are complex.
