County Directory
Norfolk Planning & Building Contacts
Norfolk County Council, 7 district and borough councils, plus the Broads Authority - covering Norwich, King's Lynn, Great Yarmouth, the Broads, Sandringham and the North Sea coast.
Local planning authorities and key consenting bodies for Norfolk
Norfolk operates a two-tier planning system. Norfolk County Council handles minerals, waste and county matters. Seven district and borough councils are the local planning authorities (LPAs) for development in their areas. The Broads Authority is the LPA for the Norfolk and Suffolk Broads - a nationally protected area equivalent to a national park covering 303 sq km. Any development within the Broads Executive Area requires planning permission from the Broads Authority, not the relevant district council.
Norfolk County Council
County-wide - minerals, waste and county matters; strategic transport and highways
Norfolk County Council determines planning applications for minerals extraction and waste facilities, and is the statutory consultee on highway matters for all district planning applications. Development requiring a new or altered access onto a county road requires Norfolk Highways approval.
Norwich City Council
Norwich city - one of England's finest medieval cities with over 1,500 listed buildings and 32 medieval churches
Development affecting the setting of Norwich Cathedral (Grade I), Norwich Castle (Grade I) or the medieval street pattern requires careful design justification and Historic England consultation. The Cathedral Close, Elm Hill and Tombland are among the most sensitive conservation areas.
Broadland District Council
Broadland - Aylsham, Wroxham, Reepham, Acle, Blofield; Broads area covered by Broads Authority
North Norfolk includes a significant stretch of the Norfolk Coast National Landscape. Most of the north coastline carries SSSI designation. Coastal change management and Shoreline Management Plans govern most of the northern and eastern coast. Development within 150m of the coastal SSSI requires Natural England consultation.
South Norfolk Council
South Norfolk - Wymondham, Diss, Harleston, Long Stratton, Loddon; Broads areas covered by Broads Authority
Great Yarmouth is a nationally significant base for the offshore wind industry. The South Denes energy zone accommodates operations and maintenance facilities for North Sea wind farms. Planning applications for cable-landing infrastructure, port-related energy development and offshore logistics bases are common here.
King's Lynn and West Norfolk Borough Council
West Norfolk - King's Lynn, Downham Market, Hunstanton, Swaffham; Sandringham Estate within this borough
King's Lynn has a designated Conservation Area and numerous Grade I and II* listed buildings including St Margaret's Church and the Custom House (both Grade I). The wider setting of Sandringham Estate is a material planning consideration for development in the surrounding area.
Breckland District Council
Breckland - Thetford, Attleborough, Dereham, Swaffham, Watton; adjacent to Breckland SPA and Thetford Forest
Breckland SPA/SAC: Development within the SPA zone or within 5km of known stone curlew nesting areas requires Habitats Regulations Assessment. Natural England operates a 400m buffer zone policy around nesting sites. Thetford Forest is the UK's largest lowland pine forest - extensive areas carry SSSI designation.
The Broads Authority
Norfolk and Suffolk Broads Executive Area - 303 sq km; the LPA for all development within the Broads
The Broads Authority has a unique third statutory purpose alongside nature and public enjoyment: protecting the interests of navigation. Boathouse construction, waterside development and moorings all require Broads Authority consent. The Broads Executive Area straddles both Norfolk and Suffolk district boundaries - check jurisdiction carefully for any waterside site.
Building Control
Building Regulations approval and inspections across Norfolk
Norfolk Building Control Partnership
Joint service covering Broadland, Breckland, Great Yarmouth, North Norfolk and South Norfolk districts
Norwich City Council and King's Lynn and West Norfolk operate their own separate building control services. Registered Building Control Approvers (private inspectors) also operate across Norfolk for Building Regulations approval.
Norwich City Council Building Control
Norwich city area - historic buildings, listed structures and conservation area works
Norfolk has approximately 4,700 listed buildings and 140 conservation areas. Norwich has one of the highest concentrations of listed buildings in England. The Norfolk Historic Environment Record (maintained by the County Council) is the primary archaeological reference for planning applications.
Norwich Cathedral
Cathedral Close Conservation Area, Norwich - Grade I listed Norman cathedral, completed 1145
Works to Norwich Cathedral or within the Cathedral Close Conservation Area require Listed Building Consent from Norwich City Council, and early engagement with the Cathedral Architect is essential. The Close contains numerous further listed buildings including the Bishop's Palace (Grade I).
Holkham Hall - Grade I Registered Park
Holkham, Wells-next-the-Sea - Palladian mansion, 25,000-acre estate on the Norfolk Coast National Landscape
Development within or adjacent to the Holkham registered landscape requires Historic England consultation and assessment of impact on the park's Grade I registered setting. The Holkham Estate fronts the Norfolk Coast National Landscape and the Holkham NNR.
English Heritage - Castle Acre Priory and Burgh Castle
Multiple Scheduled Monuments across Norfolk - Castle Acre, Binham Priory, Burgh Castle Roman fort
Scheduled Monument Consent from Historic England is required for any works affecting a Scheduled Monument. Norfolk has a large number of scheduled sites including Castle Acre Priory and Castle, Binham Priory, Burgh Castle Roman shore fort, Caister Roman fort and Baconsthorpe Castle.
Environment & Flood Risk
Coastal erosion, Broads ecology, Breckland SPA and flood risk in Norfolk
Environment Agency - Anglian Region
Flood risk, water quality, abstraction licensing and environmental permitting across Norfolk
Large areas of Norfolk are at significant flood risk - the Broads, the Fens in the south-west and the coastal strip are particularly vulnerable. Tidal flooding from the Wash and the North Sea affects much of the coast. The Shoreline Management Plan governs long-term coastal defence policy, including areas of managed retreat.
Natural England - East of England
SSSIs, SPAs, SACs, Broads ecology, Breckland SPA and Norfolk Coast National Landscape
Norfolk's ecological designations include the Norfolk Coast SAC/SPA/Ramsar, Breckland SPA (stone curlew), the Broads SAC, the Wash SPA/Ramsar and numerous SSSIs. Development proposals within or near these areas require Habitats Regulations Assessment. Happisburgh on the north-east coast has some of the fastest rates of coastal erosion in Europe.
Norfolk Coast National Landscape
451 sq km from the Wash to Sea Palling - coast, marshes, saltmarsh, dunes and heathland
Development within the Norfolk Coast National Landscape must conserve and enhance natural beauty. The coastal strip from Holkham to Cley is particularly sensitive with multiple overlapping international ecological designations. The NL Partnership is hosted by North Norfolk District Council.
Utilities & Infrastructure
Water, gas, electricity and road infrastructure serving Norfolk
Norfolk faces significant water stress - groundwater abstraction from the chalk aquifer is a key constraint on development, particularly where sensitive chalk stream ecology is present. Developers must consult Anglian Water's development services team for capacity assessments and connection approvals.
UK Power Networks (UKPN)
Electricity distribution across Norfolk - Eastern distribution zone; offshore wind grid reinforcement
Norfolk is at the forefront of the UK's offshore wind energy boom. Significant grid reinforcement works are ongoing to accommodate offshore wind cable landings from the southern North Sea. Large-scale grid connection projects require consultation with both UKPN and National Grid Electricity Transmission.
Cadent Gas
Gas distribution network across Norfolk - East of England network
Norfolk has no motorways. The A11 (London to Norwich), A47 (Peterborough to Great Yarmouth) and A17 (King's Lynn to Newark) are the principal trunk roads. Development generating significant additional traffic on these routes requires a Transport Assessment and National Highways consultation.
Trade Bodies
Key construction industry organisations serving Norfolk
Federation of Master Builders - East of England
Representing SME builders across Norfolk and the wider East of England region
RAF Marham, home of the UK's F-35B Lightning II fleet, has a substantial aviation safeguarding zone. Development including tall structures, wind turbines, solar farms, communications masts and any works that could affect radar or low-flying operations requires consultation with the Defence Infrastructure Organisation (DIO) Safeguarding team.
Marine Management Organisation (MMO)
North Sea offshore wind, marine licences and intertidal development along the Norfolk coast
Any development affecting the intertidal zone or within 200m of the coast requires a Marine Licence from the MMO. Norfolk's coast is a key corridor for offshore wind cable landings - offshore wind farm applications are typically decided by the Planning Inspectorate as Nationally Significant Infrastructure Projects.
Sandringham Estate
Sandringham, West Norfolk - Royal residence; 8,000-hectare private estate open to the public
Development affecting views towards Sandringham, or within the wider parkland setting, is a material planning consideration for King's Lynn and West Norfolk Borough Council. The Estate is a private Royal property but the grounds include Sandringham Country Park which is open to the public.
