What is planning law?

Planning law governs the development and use of land and buildings. It covers matters such as planning permissions, enforcement, development control, local plans, environmental considerations, and legal agreements like Section 106 obligations. Planning law ensures that developments align with national and local planning policies.

Do I always need planning permission for development?

Not always. Some minor works fall under permitted development rights, meaning they don’t require planning permission. However, larger developments, changes of use, or work in conservation areas usually require approval. It’s best to get legal advice early to avoid enforcement action.

What is a Section 106 agreement?

A Section 106 agreement is a legally binding planning obligation between a developer and a local authority. It ensures that a development contributes to local infrastructure, affordable housing, or community services. These agreements are often necessary to make a development acceptable in planning terms.

What is the Community Infrastructure Levy (CIL)?

CIL is a charge that local authorities can levy on new developments to fund infrastructure such as roads, schools, and healthcare. It is separate from Section 106 and applies to certain developments based on floor space created. Not all councils have adopted a CIL charging schedule.

Can I appeal a refused planning application?

Yes. If your planning application is refused or not decided within the required timeframe, you can appeal to the Planning Inspectorate. Appeals must be made within specific time limits and should be supported by clear planning and legal arguments.

What is a judicial review in planning law?

A judicial review is a legal challenge in the High Court where a claimant argues that a planning decision was unlawful—e.g., due to procedural error or irrationality. It does not re-argue the merits of a planning decision but examines whether the correct legal process was followed.
