Who determines a planning application inside a National Park

Inside the boundary of an English National Park, the National Park authority is the sole local planning authority. Your application goes to it, the fee is paid to it, its officers write the report and its members or officers decide. The district or county council whose area the Park overlaps has no development control function there, which surprises a lot of landowners who have dealt with that council about everything else for twenty years.

That single transfer of function, made by section 4A of the Town and Country Planning Act 1990, is the thing to get straight before you post anything. The rest of this explains what the Park authority holds, what it does not, and how to find the right validation list.

The Park authority as local planning authority

The Environment Act 1995 reconstituted National Park authorities as free-standing bodies and handed them the planning functions for their areas. In practice that means the Park authority prepares and adopts the local plan, determines applications, serves and confirms tree preservation orders, handles listed building consent and conservation area matters, takes enforcement action and discharges conditions.

It also means the Park authority's own policies are the development plan for your land. Section 38(6) of the Planning and Compulsory Purchase Act 2004 requires the decision to be made in accordance with that plan unless material considerations indicate otherwise, so a policy in the neighbouring district's plan carries no weight on a site inside the Park.

Members are a mix of people appointed by the Secretary of State, parish representatives and councillors nominated by the constituent local authorities. The Broads is governed by its own authority under separate legislation and holds a similar, though not identical, set of functions.

The statutory purposes shape every decision. Park authorities must conserve and enhance natural beauty, wildlife and cultural heritage, and promote understanding and enjoyment of the Park's special qualities. Where those two purposes conflict, conservation prevails. That is why a scheme which would sail through in a nearby market town gets a harder reading three fields away.

Functions it holds and functions it does not

The division is cleaner than most people expect, but it is not intuitive.

Minerals and waste is the one worth dwelling on. Everywhere else in a two-tier area those are county matters, decided by the county council. Inside a National Park the Park authority takes them, so a quarry extension or a waste transfer station on Park land is determined by the same body that decides a porch.

Highways is the opposite case. The Park authority is never the highway authority, so access, visibility and adoption are all matters on which it consults the county or unitary council and then weighs the response. If the highway authority objects on safety grounds, the Park authority can still grant permission, but rarely does.

Minerals, waste and the policy test that applies to them

Because the Park authority holds minerals and waste, it also writes the minerals and waste policies for the Park area, either in its local plan or in a separate document. Those policies sit alongside the National Planning Policy Framework's treatment of major development in National Parks, which in the current edition published in August 2026 directs that such development should be refused other than in exceptional circumstances and where it is shown to be in the public interest. Check the policy reference on gov.uk before quoting it, because the Framework was reorganised into policy codes in that edition.

Whether a proposal counts as major development for that purpose is a judgement for the decision maker, taking account of its nature, scale and setting, rather than the 10 dwelling or 1,000 square metre arithmetic used for fee and determination period purposes. A single large agricultural building can be major development in this sense. A 12 unit scheme in a Park town might not be.

Consultation, and who gets a say

Parish and town councils inside a Park are consulted as a matter of course and their views carry real weight, partly because parish members sit on the authority. The overlapping district council is usually consulted too, as are the county council's highways and ecology teams, the relevant water undertaker, Historic England where designated heritage assets are affected, Natural England on protected sites and the Environment Agency on flood risk and water quality.

Getting those responses in front of you early changes how you draft. The practical mechanics of chasing them and reading the officer's file are the same as anywhere else, and the approach set out in getting consultee responses and the officer's case file works equally well with a Park authority.

Determination periods are the standard ones: eight weeks for a minor application, 13 weeks for a major, 16 weeks where environmental impact assessment applies. Park authorities are small, with fewer officers covering a very wide area, so extensions of time are common. If nothing happens, the right to appeal against non-determination still exists, and the trade-offs in appealing non-determination or waiting apply without modification.

Permitted development is narrower here

National Parks are designated land for the purposes of the General Permitted Development Order 2015, which strips out several householder rights. Side extensions under Part 1 Class A are not permitted, rear extensions are limited to single storey, roof extensions and dormers under Classes B and C are not permitted, cladding under Class C is not permitted, and an outbuilding more than 20 metres from the house is limited to 10 square metres under Class E.

Agricultural rights under Part 6 are also tighter, with prior approval requirements pitched lower than outside designated land. And the limits apply to the original dwelling as built, not the house you bought.

A Lawful Development Certificate under section 192 is the only formal way to confirm that proposed works are lawful without permission. If the margin is narrow, buy the certainty.

Fees, validation and finding the right list

Fees are set nationally and indexed annually, and they are paid to the Park authority. Some applications attract no fee or a reduced one, and the categories are the national ones rather than anything Park-specific, as covered in planning fee exemptions and reductions.

The local validation list is where Park authorities diverge most. Expect requirements that reflect the designation: a landscape and visual appraisal for anything prominent, a dark skies or external lighting statement in Parks with a dark sky designation, a tranquillity or recreational impact note, and detailed materials and boundary treatment schedules. Download the authority's current list from its own website and work through it line by line, because a missing document is the most common reason an application is returned unvalidated.

Illustrative example, not a real case: a landowner proposing a 400 square metre livestock building with a new field access inside a Park would file one application with the Park authority, which would consult the county council as highway authority on the access, the parish council on siting, and its own landscape officer on the building's colour and roof profile. Building regulations approval would come separately from the district council. Four bodies, one application, one decision maker.

A planning statement that addresses the Park's statutory purposes directly, rather than reciting generic sustainability policy, is the single most useful document you can put in front of a Park officer.
