Check if the works are affected by an Environmental Significance Overlay

Refer to the report from Planning Maps Online to see whether the works are affected by an Environmental Significance Overlay.

You'll need Planning permission for an extension in an Environmental Significance Overlay, unless the works are:

  • Repairs and routine maintenance
  • the construction of a heating appliance, chimney or flue pipe.

Reminder: 'Repairs and routine maintenance' refers to the regular upkeep of a building or repairs to damaged building parts that do not involve the entire replacement of the building fabric.
