What is a planning application?

In simple terms, it's a formal request to build on and/or extend your property or land. In the UK any type of change or development that surpasses a certain size must be looked into and approved by your local council or planning authority.

The main goal of doing a planning application is to ensure that all new developments are safe, suitable, and built in line with local and national planning policies.

Some common reasons to apply for planning:

  • Building a new house or structure.
  • Extending an existing property.
  • Changing the use of a building (e.g., from residential to commercial).
  • Major alterations that affect the external appearance.
  • Significant landscaping or engineering works.

What is normally included in a planning application:

  • The application forms with detailed information about the project.
  • Site plans and elevation drawings.
  • A design and access statement (for certain applications).
  • Supporting reports (e.g., environmental, transport, or heritage reports).

After you submit your planning application (and pay the fee) the process of getting approval usually follow these steps,

  1. Validation – The local authority checks all necessary documents are included.
  2. Consultation – Neighbours, relevant agencies, and the public may be invited to comment.
  3. Assessment – Planning officers review the proposal against planning policies.
  4. Decision – The application is approved or refused, typically within 8–13 weeks.

Do I need a planning application?

In most cases, yes — if you're building something new, making big changes to your home, or changing how a building is used, you'll probably need planning permission. In some cases, smaller changes would come under permitted development. Planda uses real planning data and local policy insights to give you a straight answer, so you can plan with confidence — not crossed fingers.

Navigating planning policies:

Making sense of the UK’s planning system can feel like a guessing game. Local planning policies are complex, vary between councils, and are often hard to interpret unless you’re a professional. Even then, advice can be subjective; one consultant’s “should be fine” might be another’s “probably not.” For homeowners, architects, and developers alike, this creates uncertainty, delays, and unnecessary costs.

Instead of relying on vague opinion, Planda uses data-driven insights to assess your planning application. By analysing local authority decisions, policy documents, and historical outcomes, it offers evidence-backed advice tailored to your location and project. 

How can I increase my chances to get my application approved?

The traditional planning process can be full of questions marks, weeks of waiting and disappointing results. How can you improve your chances of getting your planning application through the first time?

Typically the options were fairly costly, paying for a professional consultation before starting any drawings, then the option to double down with preapplication advice on the done plans to highlight any suggested amendments - coming in at around £300 per consultation.

This is where Planda comes in; it removes the need to pay high fees for planning consultants and get the answers you need in seconds. Planda breaks down your likelihood of the major residential project instantly, and instead of giving opinion based advice, it will look into all the similar plans to give you data backed direction.

Additionally, it removes the possibility of any amendment fees incurred if the planning application gets refused. Submitting confidently means no paying the architect second time to redo those drawings, and no waiting around for a second review.
