National Park authorities: how they differ as your council

If your land sits inside an English National Park, the National Park authority is your local planning authority, not the district or county council. It writes the local plan, validates and determines applications, handles listed building consent and enforcement, and answers pre-application enquiries. The district still collects your bins and runs building control, and the county is still the highway authority. That split catches out owners who send an application to the wrong address and lose three weeks.

Which functions the authority holds and which stay elsewhere

National Park authorities were established as free-standing bodies under Part III of the Environment Act 1995. They took the planning function wholesale, so within the park boundary the authority does development plan making, development management, listed building and conservation area consent, tree preservation, and enforcement.

Almost everything else stayed put.

The practical effect is that a single project can involve three organisations. A barn conversion needs permission from the park authority, building regulations approval from the district, and a section 184 licence from the county for any new vehicle crossing. Sequence those, because each has its own clock.

Statutory purposes and how they steer decisions

National Park authorities carry two statutory purposes, set out in the National Parks and Access to the Countryside Act 1949 as amended by the Environment Act 1995. The first is to conserve and enhance the natural beauty, wildlife and cultural heritage of the area. The second is to promote opportunities for public understanding and enjoyment of the park's special qualities.

Where the two conflict and the conflict cannot be reconciled, conservation takes priority. That principle shapes decisions on visitor attractions, holiday accommodation and access improvements far more than most applicants expect.

Alongside the purposes sits a duty to seek to foster the economic and social well-being of local communities within the park. It is a duty rather than a purpose, which is a real distinction. It supports a farm diversification case. It will not outweigh conservation harm on its own.

The Levelling-up and Regeneration Act 2023 strengthened the duty on relevant public bodies from having regard to the purposes to seeking to further them. Check the commencement position for the specific provision before relying on the stronger wording in a submission.

Restricted permitted development inside the park

National Parks are article 2(3) land under the General Permitted Development Order 2015, along with conservation areas, National Landscapes and the Broads. That designation strips out several householder rights that apply elsewhere.

• No cladding of the exterior with stone, timber, tiles or render under Class A.
• No side extensions under Class A, and no roof extensions or dormers under Class B.
• No larger home extension prior approval route, so a deep rear extension needs full permission.
• Outbuildings over 10 m² in total are not permitted more than 20 m from any wall of the house.
• Tighter limits on solar installations, and additional restrictions on agricultural development under Part 6.

Agricultural permitted development is where rural owners meet the difference most often. Inside a park, more agricultural building work needs prior approval or full permission than outside it, and the sizes allowed are smaller. Check the current text of Part 6 rather than relying on what a neighbour did on land outside the boundary.

Because the boundary matters this much, confirm it before you design anything. A holding that straddles the line can have two authorities and two sets of rights on the same farm. A Lawful Development Certificate is the only formal way to confirm that works are lawful, and inside a park that certainty is usually worth the fee.

Local plan and design guidance you must cite

Each park authority adopts its own local plan, and those plans tend to carry unusually specific design and materials policies: local stone, slate roofs, limits on rooflights, dark skies lighting policies, restrictions on domestic curtilage extending into open moorland.

Most authorities also publish design guidance as supplementary planning documents, covering conversions of traditional farm buildings, boundary treatments and the treatment of new dwellings in the open countryside. Quote them by name and date in your supporting statement, exactly as you would quote a development plan policy, and the approach in our note on local plan policy references for a rear extension transfers directly.

National policy adds weight on top. The National Planning Policy Framework (August 2026 edition) gives great weight to conserving and enhancing landscape and scenic beauty in National Parks, and applies a restrictive test to major development in them, permitting it only in exceptional circumstances and where it is in the public interest. Verify the current policy code and wording on gov.uk before quoting it, because the August 2026 edition replaced paragraph numbers with codes.

Conservation areas exist inside parks as well, and their appraisals are just as usable as evidence. Our guide to using conservation area appraisals to justify a design covers how to mine them for the character features an officer will test your scheme against.

Committee structures and parish involvement

Park authority membership is drawn from three sources: members appointed by the constituent county, unitary and district councils, members appointed by parish councils within the park, and members appointed by the Secretary of State. That mix produces a planning committee with a stronger landscape orientation than a typical district committee.

Delegation schemes vary. Some authorities delegate almost all householder decisions to officers, others refer more to committee, particularly where the parish has objected. Find the authority's scheme of delegation on its website and read the trigger for committee referral before you assume a straightforward application will be decided by an officer.

Parish and town councils inside parks are consulted as a matter of course, and their views carry practical weight because their appointees sit on the authority. Speaking to the parish before you submit is worth more here than in most places.

Fees, obligations and levies inside a park

Planning application fees are set nationally by regulations and are the same inside a park as outside it, and they are indexed, so use the current schedule rather than an old figure. Pre-application charges are set locally by each authority and vary widely, so check the published fee list. Our note on working out the fee before you submit sets out how the national scale is structured.

National Park authorities can be Community Infrastructure Levy charging authorities and some have adopted a charging schedule. Where a park authority has not, the district's schedule does not apply inside the park boundary. Ask the authority directly, and confirm whether any self-build or residential extension exemption applies to your project before you start work, because those exemptions must be claimed in advance.

Section 106 obligations inside parks often deal with local occupancy restrictions on new dwellings, and those restrictions run with the land. Read the draft heads of terms carefully before you agree them.
