Do I need permission for external lighting or floodlights?

Ordinary domestic external lighting on a house does not normally require planning permission, but floodlighting that causes light spill or glare onto neighbouring property or the public road can amount to development and attract enforcement or nuisance action.

Small wall-mounted lights and security lights on a house are treated as part of normal domestic use. Larger installations — tennis court or yard floodlighting, tall columns, or commercial-scale luminaires — are more likely to need permission.

Even where permission is not required, obtrusive light can be pursued as a private nuisance, and planning conditions on newer estates sometimes restrict external lighting.

Good practice

  • Aim luminaires downwards with cut-off optics
  • Use motion sensors and timers rather than dusk-to-dawn operation
  • Keep column heights low
  • Avoid lighting that could dazzle road users
