Special Areas of Conservation.

Europe’s strictest habitat protection, retained in domestic law. A scheme that could affect one — even from some distance — needs a habitats regulations assessment before permission can be granted.

The assessment applies to effects, not adjacency, so sites well outside the boundary can be caught.

the test that applies
What is and isn’t allowed
Generally workable
  • Development outside any zone of influence
  • Schemes contributing to a strategic mitigation tariff
  • Proposals with secured alternative recreational space
Needs careful handling
  • Housing within a recreational pressure zone
  • Schemes affecting water quality or abstraction
  • Anything requiring in-combination assessment
Rarely acceptable
  • Development causing adverse effect on integrity
  • Schemes relying on unsecured mitigation
The statutory test

A competent authority may only grant permission after ascertaining that the scheme will not adversely affect the integrity of the site, alone or in combination with other plans and projects. Where that cannot be ascertained, permission must be refused unless there are imperative reasons of overriding public interest and compensatory measures.

The trigger is likely significant effect, not location. Recreational pressure from new housing, water abstraction and air quality from traffic all reach beyond the boundary, which is why authorities operate zones of influence and, in some places, mitigation tariffs.

Before you submit

The in-combination test catches schemes that look harmless alone. Check whether the authority operates a tariff or a strategic mitigation strategy — where one exists, joining it is usually faster and cheaper than arguing the point scheme by scheme.

What isn’t here yet

How schemes actually fare inside this designation — approval rates, appeal survival, which authorities apply it hardest — needs the designation joined to the decision record. That join isn’t built, so those figures aren’t published here. We won’t estimate them.

Check the zone of influence, not just the boundary — a site kilometres away can still trigger assessment.
