Planning Permission in New Forest National Park
National Park Authority in England · Last updated April 2026
The New Forest National Park covers 220 square miles of ancient woodland, heathland, and coastal marshes in Hampshire. The NPA handles all planning within the park boundary. With 15 conservation areas and 26 Article 4 directions, planning in the New Forest is carefully controlled to protect the park's unique landscape of commoning, ancient trees, and free-roaming ponies.
The NPA processes around 490 applications annually with a 94.1% approval rate — one of the highest among national parks. The New Forest's planning policies balance heritage protection with the needs of the park's residential communities, many of whom live in traditional forest-edge settlements.
Homeowners should consult the New Forest Local Plan before starting any work. The park's unique character and extensive Article 4 directions create specific planning requirements.

Permitted development in New Forest National Park
The New Forest has more restrictive PD rights as a national park, and the 26 Article 4 directions remove further PD rights in many residential areas. These directions typically cover changes to windows, doors, roofing, boundary fences, and painting — reflecting the sensitivity of the forest landscape. The combination of national park restrictions and Article 4 directions means that many homeowners need planning permission for changes that would be PD elsewhere.

Most solicitors will ask for one when you come to sell, remortgage, or insure your property.
New Forest National Park decided 334 householder applications in the year ending september 2025. Their 8-week performance of 78.1% is below the national average of 93%, so LDC applications may take longer than the 8-week target.
