Permitted development

What is a permitted development?

Permitted development refers to the permission to carry out certain forms of development without the need to make an application to a local planning authority, as set by the Government.

This does not affect the need for building regulations approval.

Changes to the system

On 1 October 2008 changes to the Town and Country Planning (General Permitted Development) Order 1995 (GPDO) came into force. The legislation represents a significant change to the previous system, including:

  • a new permitted development regime for householders (Part 1 of Schedule 2 - amendment) and
  • World Heritage Sites now have same levels of protection from permitted development as other designated areas such as conservation areas (Part 2 of Schedule 1 - addition).

In view of the extent of the changes to the "permitted development" regime, we will no longer be able to respond to letters enquiring as to whether or not planning permission is required. If you wish to gain a formal decision as to whether or not planning permission is required you will need to submit for a Lawful Development Certificate for a Proposed use or development. There is a fee for this service.

Overview of changes

The new regulations govern the types of extensions to dwelling houses which can be carried out without the need for planning permission. The new system includes:

  • more focus the dimensions of the proposed addition or outbuilding, e.g. height and floor area (not volume), its position and its proximity to boundaries
  • restrictions to the paving of front gardens and
  • the inclusion of chimneys/flues and soil/vent pipes.

In general this means that more house extensions will not require the submission of a planning application, but also that some types of development, including hard surfaced driveways and new side windows, are subject to greater control.

The changes are intended to reduce the need for people to apply for planning permission for straightforward home improvements such as loft conversions or extensions while still protecting the interests of neighbours, the wider community and the environment. The new restrictions on hard surfacing are intended to reduce the potential contribution to flood risk from surface water run-off.

In some local areas permitted development rights are more restricted. If you live in a Conservation Area, a National Park, or an Area of Outstanding Natural Beauty you will still need to apply for planning permission for certain types of work which do not need an application in other areas. There are also different requirements if the property is a listed building.
