The Broads and its own planning authority
Sites in the Broads executive area are decided by the Broads Authority, not the district council. Here is what its navigation duty, restricted permitted development rights and tidal flood risk mean for an application.
If your site sits inside the Broads executive area, the Broads Authority is your local planning authority. Not Broadland District Council, not Great Yarmouth, not South Norfolk, not East Suffolk. Those councils still empty your bins and run building control, but Broads Authority planning decisions are taken by a body created by its own Act of Parliament, working to its own local plan, with a statutory duty to protect navigation that no other planning authority in England carries.
That split catches people out. An agent who has worked across Norfolk for years will still occasionally lodge a householder application with the district and lose three weeks finding out.
Why the Broads sits outside the National Park framework
The Broads Authority was set up by the Norfolk and Suffolk Broads Act 1988 and took up its functions the following year. It is not a National Park authority. The 1988 Act gave it a distinct set of purposes: conserving and enhancing the natural beauty, wildlife and cultural heritage of the Broads, promoting public understanding and enjoyment of the area's special qualities, and protecting the interests of navigation.
The area is usually described as having a status equivalent to a National Park, and national policy treats it that way for landscape protection. The National Planning Policy Framework names the Broads alongside National Parks and National Landscapes when it directs great weight to conserving landscape and scenic beauty. The Framework was re-issued on 17 August 2026 with policy-coded chapters, so check the current code on gov.uk before you quote it in a planning statement rather than copying a paragraph number from an older document.
The practical difference from a National Park is the third purpose. Navigation is not a background consideration here. It is written into the Authority's remit, and it shapes decisions on moorings, boatyards, bank treatment and anything built at the water's edge. If you have read about the statutory purposes test that applies in a National Park, the Broads version has an extra limb.
What the navigation duty adds to an application
Planning permission is not the only consent a waterside scheme needs. Works in or over the water, to banks and to moorings can require separate consent from the Authority in its navigation role, and that runs on its own timetable. Two consents, one body, different teams.
Applicants who assume the planning permission carries the navigation works with it end up applying twice anyway, in sequence rather than in parallel. Ask early which regime bites.
The duty also colours how officers read a proposal. A quay heading rebuilt in sheet piling reads differently from one rebuilt in timber, because the Authority is weighing bank stability, habitat, the character of the reach and whether a boat can still get alongside safely.
Permitted development is narrower than it looks
The Broads is article 2(3) land under the Town and Country Planning (General Permitted Development) (England) Order 2015. That single definition removes or shrinks a long list of householder rights that apply elsewhere in England.
| Right elsewhere in England | Position on Broads land |
|---|---|
| Class A side extension to a house | Not permitted development |
| Larger home extension prior approval (up to 6m or 8m) | Not available |
| Class AA additional storey on a house | Not permitted development |
| Cladding to an external wall | Not permitted development |
| Class E outbuildings more than 20m from the house | Limited to 10 m² in total |
Agricultural rights under Part 6 and telecommunications rights under Part 16 also carry tighter conditions. And an Article 4 direction may remove more on top, so check the constraint layers for the specific holding rather than assuming the standard position.
None of this makes the works unlawful. It makes them an application rather than an assumption. A Lawful Development Certificate is the only formal way to confirm that works are lawful, and it is worth the fee when a sale or a mortgage will later depend on the answer.
Flood risk in a landscape at or below sea level
Large parts of the executive area sit in Flood Zone 3, much of it tidal, behind embankments that are managed rather than guaranteed. A Flood Risk Assessment is expected for sites in Flood Zone 2 or 3 and for sites of one hectare or more anywhere, and on most Broads sites the assessment does real work rather than filling a validation box.
Expect the Authority and the Environment Agency to look at four things in particular: finished floor levels set against a modelled level plus a climate change allowance, safe access and egress during a design event, whether the development displaces floodplain storage, and what happens in the residual case when a defence is overtopped. Raising ground levels to lift a building out of the flood zone is the move that most often fails, because the water that no longer sits on your plot has to sit somewhere else.
Where the sequential approach applies, the Sequential Test comes first and the Exception Test only afterwards. Climate change allowances are revised periodically, so take the current figures from the Environment Agency rather than from a neighbouring scheme's report.
Water quality is the other half of the picture. Parts of Norfolk and Suffolk fall within catchments where Natural England has advised that nutrient loading must be neutralised before permission can be granted, and the arithmetic is closer to the one used to prove water neutrality than to anything in a standard drainage strategy. Check the current catchment position for your parish before you programme the application.
Landscape, habitat and waterside design
The Broads is one of the flattest developed landscapes in England, which means roof lines, chimneys and even a row of solar panels read across long distances. Officers look hard at the skyline, at boundary treatment and at whether a building sits below or above the tree line when seen from the water.
Habitat designations overlay most of it. The Broads carries European site designations, wetland designations of international importance and a dense pattern of Sites of Special Scientific Interest. Where a proposal could have a likely significant effect on a European site, the Authority must carry out an appropriate assessment under the habitats regulations before it can grant permission, and that assessment needs evidence from the applicant to be workable.
Reed, fen and open water habitats also make biodiversity net gain arithmetic unusual. Watercourse units and the condition assessment of fen habitat are not things a general practitioner should attempt from a desk. Get a suitably qualified ecologist onto the site in the right season.
Many of the drainage mills, staithes and boat sheds are listed or sit within conservation areas, and the reasoning that applies in a National Landscape to the duty on decision makers is a useful comparison for how much weight designation attracts.
Consultation and how decisions are taken
Applications are publicised in the usual way, with a consultation period of at least 21 days, and parish and town councils are consulted as they would be anywhere. The difference is the range of bodies with a standing interest: the navigation function inside the Authority, the Environment Agency, Natural England, the internal drainage board for the relevant level, and the district council for matters that remain with it.
Decisions are taken by officers under delegated powers or by the Authority's planning committee. Committee reports are published in advance, and reading two or three recent ones for a comparable site tells you more about how a policy is being applied than the policy text does.
The documents a Broads site usually needs
Most applications here run heavier than an equivalent inland site. A typical waterside residential scheme ends up with a planning statement, a design and access statement, a flood risk assessment, a drainage strategy, a preliminary ecological appraisal and a biodiversity net gain assessment, with a heritage statement and a landscape and visual assessment added where designations bite. You can see how those fit together across the full set of report types and which of them a constrained site tends to trigger.
Start with the constraint check, not the drawings. On a Broads site the constraints decide the footprint, the levels and often the roof form before an architect puts a pen down.

Frequently asked questions
Which council decides a planning application in the Broads?
The Broads Authority is the local planning authority for the Broads executive area, even though the site also sits inside a district such as Broadland, Great Yarmouth, South Norfolk or East Suffolk. Those district councils keep other functions, including building control and waste collection. Check the executive area boundary before you submit, because an application sent to the wrong authority will simply be returned.
Is the Broads a National Park?
No. It was created by the Norfolk and Suffolk Broads Act 1988 as a separate authority with its own purposes, one of which is protecting the interests of navigation. National policy gives the Broads landscape protection comparable to a National Park, and the National Planning Policy Framework names it alongside National Parks and National Landscapes when directing weight to landscape and scenic beauty.
Do normal permitted development rights apply in the Broads?
Only in part. The Broads is article 2(3) land under the General Permitted Development Order 2015, which removes side extensions and additional storeys on houses, blocks cladding, withdraws the larger home extension prior approval route and caps outbuildings more than 20 metres from the house at 10 square metres in total. An Article 4 direction can remove more.
Will I need a flood risk assessment for a Broads site?
Almost certainly, because much of the area lies in tidal Flood Zone 3. An assessment is expected for any site in Flood Zone 2 or 3 and for sites of one hectare or more. It needs to set finished floor levels against a modelled level plus a current climate change allowance, show safe access during a design event and demonstrate no loss of floodplain storage.
Do I need separate consent for works to a bank or mooring?
Possibly. The Broads Authority holds navigation functions as well as planning functions, and works in or over the water, to banks and to moorings can need consent under that separate regime. Planning permission does not carry it. Ask the Authority which consents apply at the earliest stage so the two applications can run together rather than one after the other.
