Commentary on Sections Part 4: Development Control Section 51: Duration of permission and consent
81.Section 51 amends sections 73, 91 and 92 of the Town and Country Planning Act 1990 and sections 18 and 19 of the Planning (Listed Buildings and Conservation Areas) Act 1990. It reduces the period of validity of a planning permission, a listed building consent and a conservation area consent from five to three years. But local planning authorities may still direct longer or shorter periods where this would be appropriate. It also prevents an extension to the agreed period of validity without the submission of a new application.
