The green belt is a specially designated area of countryside protected from most forms of development. It is protected to help stop urban sprawl, preserve the character of existing settlements and encourage development within existing built-up areas.

The government are working on improving access to public land records, allowing you to check certain restrictions on land. You can view their progress here and see whether your land is greenbelt (note: this tool is currently under development).

You should contact your local planning authority to find out if your land is in a green belt area, and any policies or restrictions that may apply as a result.

‍

A designated area is situated within a World Heritage Site, Conservation Area, Site of Special Scientific Interest, National Park, or an Area of Outstanding Natural Beauty, the area is protected by law due to its architectural or historic interest or landscape.

Due to this protection, there will be further limits on what you can do to your property if it is within such an area, for example building an extension, changes to the roof, or work to trees. Restrictions will be put in place and permitted development rights will not apply.

If you live in a designated area, you must seek advice from your local planning authority before starting any work.

If an outdoor kitchen is not a permanent structure, then planning permission will normally not be required.

Where planning permission is required, it may be granted through permitted development rights, provided it meets the limits set out in legislation. Most outdoor kitchens fall within the set limits unless they are particularly tall or close to a boundary.

While there is no specific permitted development right for ‘outdoor kitchens’ it may be classified as an ‘outbuilding’.

You can view the limitations for outbuildings and outdoor kitchens in the relevant common project

If the structure exceeds the limits set out through permitted development rights, then it will require an application for planning permission.

Different rules may apply if you live in a listed building or conservation area. If this is the case, you may wish to consult your local planning authority.

Read about the building regulations that cover outdoor kitchens.

Significant changes to insulation and thermal elements would normally require building regulations approval. The extent to which this applies depends on the existing insulation and what it will be replaced with.

If the work is completed by a member of a competent persons scheme, then an application for approval will not be required.

Find out more about insulation and building regulations on our common projects.

The failure to obtain planning permission or comply with the details of a permission is commonly known as a 'planning breach'.

A planning breach usually occurs when:

• A development that requires planning permission is undertaken without the permission being granted - either because the planning application was refused or was never applied for
• A development that has been given permission subject to conditions breaks one or more of those conditions.

If the breach involves a previously rejected development (or the retrospective application fails) the council can issue an enforcement notice requiring you to put things back as they were.

There are statutory time limits for enforcement, these vary based on when the breach took place.

If the breach took place prior to 25 April 2024

• Change of use of a building, or part of a building, to use as a single dwelling house - Enforcement action can no longer be taken once the unauthorised use has continued for four years without any enforcement action being taken
• Operational development relating to building, engineering or mining - Enforcement action can no longer be taken from four years, beginning the date where the operations were substantially completed.

If the breach took place on or after 25 April 2024

• Change of use of a building, or part of a building, to use as a single dwelling house - Enforcement action can no longer be taken once the unauthorised use has continued for ten years without any enforcement action being taken
• Operational development relating to building, engineering or mining - Enforcement action can no longer be taken from ten years, beginning the date where the operations were substantially completed.

Other time limits:

There is no time limit for enforcement on breaches of planning control relating to relevant demolition.

For any other breach of planning control, ten years beginning with the date of the breach. This predominantly applies to changes of use.
