Areas of outstanding natural beauty

What are AONBs?

Areas of outstanding natural beauty (AONBs) are areas of countryside in England and Wales outside national parks which are designated in recognition of their significant landscape value. The primary purpose of AONB designation is 'to conserve and enhance the natural beauty of the landscape'.

Two secondary aims complement this purpose:

•
to meet the need for quiet enjoyment of the countryside
•
to have regard for the interests of those who live and work there

On 22 November 2023, all designated AONBs in England and Wales were rebranded as ‘National Landscapes’, although they are still referred to as AONBs in legislation and policy.

See Practice Notes: Areas of outstanding natural beauty (National Landscapes), Biodiversity and nature—protected sites and Non-statutory designated areas.

Responsible authorities

Natural England, Natural Resources Wales, Department of the Environment, Food and Rural Affairs (Defra), and local planning authorities (LPAs) all play a role in designating and enforcing AONBs.

Court confirms a breach of planning control need not be ‘live’ when an enforcement notice is issued (Paton and Paton v SoSLUHC)

Planning analysis: The court held that an inspector had correctly applied section 174(2)(b) of the Town and Country Planning Act 1990 (TCPA 1990) in an appeal against an enforcement notice (EN). The inspector had identified that to make out a ground (b) appeal, an appellant is required to demonstrate that the alleged breach of planning control had not occurred within an enforceable period. The appellants had argued that a ground (b) appeal should succeed if, at the date of the issue of the EN, the alleged breach of planning control was no longer ongoing. The court agreed that, giving the statutory wording its ordinary and natural meaning supported the inspector’s analysis and adopting this approach could not support the appellant’s proposed construction of ground (b). This conclusion was buttressed by a contextual and purposive interpretation of the enforcement regime. Written by Rowan Clapp, a barrister at Cornerstone Barristers.
