Part 33 of Schedule 2 to the Town and Country Planning (General Permitted Development) Order 1995 grants permitted development rights for the installation, alteration or replacement on buildings or other structures (such as walls, fences or poles) of CCTV cameras for security purposes, subject to specified limits on size, numbers and positioning. Part 33 does not apply to listed buildings. Nor does it give permitted development rights to poles or other structures specially constructed to hold cameras.
