What is an AONB?
An Area of Outstanding Natural Beauty (AONB) is an area of countryside in England, Wales (Ardaloedd o Harddwch Naturiol Eithriadol) or Northern Ireland which has been designated for conservation due to its significant landscape value. Areas are designated in recognition of their national importance, by the relevant public body: Natural England, Natural Resources Wales, or the Northern Ireland Environment Agency. In place of AONB, Scotland uses the similar national scenic area designation. Areas of Outstanding Natural Beauty enjoy levels of protection from development similar to those of UK national parks, but unlike with national parks the responsible bodies do not have their own planning powers.
An AONB is a statutory designation stemming from the Countryside and Rights of Way Act 2000, which applies to England and Wales. The designation means that local authorities have: “a permissive power to take action to conserve and enhance the natural beauty of the AONBs in their areas.”
An AONB may straddle a number of local planning authority areas and as such, to ensure a consistent approach and continuity of advice, there is often an AONB Board that will be consulted with regards to planning applications. These applications will also be considered against the specific AONB policies in a local development plan. Some permitted development rights still exist in AONBs
AONBs sit between International designated areas and local designated areas.
There are 46 AONBs around the UK of which 33 are in England.
