Commentary on Sections Part 4 — Conservation Areas Section 160 — Exercise of planning functions: general duty relating to conservation areas
601.Subsection (1) of section 160 places a duty on any person, in exercising a planning function in relation to a building or other land in a conservation area, to have special regard to the desirability of preserving or enhancing the character or appearance of the conservation area. This is a wide-ranging duty because there are many planning functions (see paragraphs 604–07 below) and the duty applies to anyone exercising them (as long as the person is doing so in relation to a building or other land in a conservation area).
602.In case law (South Lakeland District Council v Secretary of State for the Environment and another [1992] 1 ALL ER 573), “preservation” has been understood as doing no harm to a conservation area’s existing character or appearance. Enhancement will improve the character or appearance, for instance by removing a derelict building that is an eyesore and harms the character of the conservation area.
603.The duty under section 160 applies to any person, so it applies not just to planning authorities but also, for instance, to the Welsh Ministers and planning inspectors.
604.The duty applies when a person is exercising a “planning function”, defined by subsection (2) as a function conferred or imposed under or by virtue of:

607.The duty, for instance, would apply when a planning authority is deciding whether to grant planning permission to carry out a development under section 58(1) of the 1990 Planning Act. Accordingly, in deciding whether to grant the planning permission, the authority must have special regard to the desirability of preserving or enhancing the character or appearance of the conservation area in which the building is situated.
608.“Building” and “land” have the meanings given by section 210 of the Act.
