Special Protection Area (SPA)
Habitat for rare and migratory birds
A Special Protection Area (SPA) safeguards rare, vulnerable and migratory wild birds and their habitats. Estuaries, heathland, wetland and coastline are typical. SPAs and Special Areas of Conservation form the UK national site network, and Ramsar sites carry equivalent protection. Each UK nation's conservation body classifies its own sites, and the Joint Nature Conservation Committee holds the UK register.
What This Means
An SPA reaches the habitat, not the house. Nothing about it touches everyday use, upkeep or internal work. It gives nobody a right to walk across your garden either; access rights come from separate footpath and open-access designations. New building is the pressure point, especially anything that adds visitors to the birds' habitat. In England a new dwelling inside a site's zone of influence usually funds alternative greenspace or a recreation levy. An extension to this house rarely triggers that, though the planning authority will still screen it. This does not normally affect mortgage approval, buildings insurance or resale.
Practical Advice
- Ask your conveyancer to confirm whether this plot sits inside the SPA or inside its wider zone of influence.
- Ask the local planning authority what mitigation a new dwelling here would owe, since the tariff is set site by site.
- Check the local search for an Article 4 direction, which would remove permitted development rights that are otherwise automatic.
- Ask the seller's solicitor for evidence that any past extensions received planning consent.
- Apply for a Lawful Development Certificate where the consent history for past works is doubtful.
Key Points
- Around the Thames Basin Heaths SPA no net new home is permitted within 400 metres, while homes between 400 metres and 5 kilometres must fund alternative greenspace and access management.
- Around the Solent, Natural England's 2019 nitrogen advice stopped councils permitting new homes until each scheme could buy nutrient mitigation.
Additional Information
A zone of influence is set locally, not nationally. The local plan or a habitats supplementary planning document maps it, so the distance that matters differs from one SPA to the next, and some carry no zone at all.
