Planning Permition and
Permitted Development for Extensions

Key differences between Planning Permission
& Permitted Development

Planning Permission:

  • Requires an application to the local planning authority.

  • Involves detailed plans and often consultation with neighbors and local authorities.

  • Can be more flexible, allowing for larger or more significant changes.

  • Approval is not guaranteed and can take time (usually a few months).

  • May involve fees and potential objections from neighbors.

Permitted Development:

  • Allows certain changes/extensions without the need for a planning application.

  • Governed by a set of rules and guidelines set by the government.

  • Typically covers smaller changes/extensions, like loft conversions or rear extensions within certain size limits.

  • Can be quicker and cheaper than seeking planning permission.

  • Still subject to certain restrictions and conditions, like not being in a conservation area or affecting a listed building.

  • Neighbors generally have less say in the process, though they can still raise concerns if they feel the development doesn't meet permitted development rules.
