Planning Permission in Forest of Dean
Non-Metropolitan District in South West · Last updated April 2026
The Forest of Dean is a distinctive district in west Gloucestershire, centred on the ancient Royal Forest between the rivers Severn and Wye. With 54 conservation areas, no Article 4 directions, and 1,486 listed buildings, the district combines the unique forest landscape with historic market towns and the Wye Valley AONB.
The council handles around 640 applications annually with a 90.5% approval rate. The Forest of Dean's planning landscape is shaped by the National Forest designation, the Wye Valley AONB, and the distinctive industrial and mining heritage that gives the area its unique character.
Homeowners should consult the Forest of Dean Core Strategy and Allocations Plan for guidance on development. The forest's unique status and heritage designations mean careful consideration is needed for many proposals.

Permitted development in Forest of Dean
The Forest of Dean has 54 conservation areas but no Article 4 directions and no Green Belt, meaning standard PD rights apply outside conservation areas. The 1,486 listed buildings are the main additional constraint. Parts of the district fall within the Wye Valley AONB, where landscape impact is a consideration. The National Forest area has its own planning considerations, but standard PD rights are not affected by forest designation alone.
What Forest of Dean expects from your project
Local Plan: Forest of Dean Local Plan Review 2026
Forest of Dean's development plan relies on saved policies from its 2005 Local Plan Review, supplemented by the Core Strategy Preferred Options. The district covers the Forest of Dean itself (a Special Area of Conservation), the Wye Valley AONB and the settlements of Cinderford, Coleford and Lydney.
Emerging / replacement plan
Forest of Dean is preparing a new Local Plan 2041. A Regulation 19 Pre-Submission plan was consulted on in 2023–2024, with submission to the Planning Inspectorate anticipated in 2025 and adoption targeted for 2026.
54 conservation areas
Forest of Dean has a high number of conservation areas. Check whether your property falls within one before starting any work — conservation area status significantly restricts what you can do without planning permission.
90.5% approval rate
Forest of Dean approves 90.5% of planning applications, above the national average of 86.9%. Well-designed residential applications in this area tend to have a good chance of success.
Conservation areas in Forest of Dean
54 designated conservation areas
The 54 conservation areas in the Forest of Dean protect a distinctive range of historic environments — from the medieval market towns of Coleford, Cinderford, and Lydney to the forest-edge villages and the Wye Valley settlements of Tintern and St Briavels. The district's industrial heritage of coal mining, iron working, and stone quarrying gives many conservation areas a unique character quite different from the typical rural Gloucestershire village.
