Understanding Planning

From validation to decision, here's what happens after you submit your application and how Planda Portal helps you navigate each stage with confidence.

What is planning permission?

Planning permission is the formal approval from your local planning authority that allows a proposed change to land or buildings. Whether that’s a home extension, a new development or a change of use - to go ahead lawfully.


Planning Permission

Required for larger projects - loft conversions, extensions, new builds, major alterations, or changing a property functionality.

Understanding Development Plans:

A Development Plan is the local authority’s official blueprint for land use and development. When you apply for planning permission, your proposals are checked against this plan - including building size, use, siting, layout, access and impact - to see if they comply with local policies and guidance.

A local plan is the key document produced by your local planning authority that sets out planning policies and land allocations for the area, identifying where new homes, businesses and infrastructure can go, while protecting important green spaces and heritage. It is prepared with public consultation, independently examined, and once adopted becomes the main basis for determining planning applications.

Please note:

Most applications are decided by planning officers, while larger or contentious cases go to a committee of councillors who make the final decision. Outcomes must follow planning policy and material considerations, not the level of public opposition.

Do I need an architect?

Once you know your project requires planning permission, the next step is preparing drawings, site plans and supporting documents that meet design, technical and planning standards.

A registered architect can guide the process, ensure work is professionally prepared, and help you meet the requirements for a successful application.

How long does it take?

From validation to decision, here's what happens after you submit your application, and how Planda Portal helps you navigate each stage with confidence.

Validation

Consultation

Permission granted

If Delayed or Refused

Validation

Once submitted, your local planning authority (LPA) checks your application is complete before formal processing begins. This prevents delays later.

What's checked:

Standard forms, mandatory national requirements, and local list items.

Timelines

3-5 working days for minor applications, up to 10 days for major ones.
Once validated, you receive confirmation, an application reference number, and your case appears on the public planning register.

Your responsibilities

Submit complete, accurate information upfront. If a non-validation decision seems unreasonable, discuss it or escalate under Article 12 (DMPO 2015). Appeals for non-determination are possible in rare cases.
