Planning permission vs listed building consent
Written by Ryan Nair, Founder, Vestige · Updated 18 April 2026
Planning permission and listed building consent are two distinct statutory consents under different Acts. Understanding the difference, and when both are required, is the foundation of any project involving a listed building.
Quick answer
Planning permission is required under the Town and Country Planning Act 1990 for development, broadly, building, engineering or material changes of use. Listed building consent is required under the Planning (Listed Buildings and Conservation Areas) Act 1990 for any works affecting the special interest of a listed building. The two are separate consents, with separate tests and separate decisions, and many projects need both.
Two distinct regimes
Planning permission focuses on external change, land use and amenity. The threshold is "development" as defined in section 55 of the 1990 Act. Permitted development rights remove the need for express permission for many minor works, subject to conditions and limitations.
Listed building consent focuses on the building's character as a building of special architectural or historic interest. The threshold, set by section 7 of the 1990 Act, is whether the works affect that character. There is no permitted development equivalent. Internal works that affect significance require LBC even where they would be invisible from outside.
When you need both
- External extensions to a listed building
- Replacement of windows or doors visible from the public realm
- New openings on principal elevations
- Change of use of all or part of a listed building
- Demolition (in whole or in part) of a listed building
- External alterations affecting both significance and amenity
When you only need LBC
- Internal alterations affecting historic fabric (walls, joinery, plaster, fireplaces)
- Like-for-like replacement of internal services routed through historic fabric
- Removal or reinstatement of internal historic features
- Most internal subdivision or layout changes
When you only need planning permission
- Works to a non-listed building in a conservation area (subject to Article 4 directions)
- Development on a curtilage building that pre-dates 1948 but is excluded by listing scope
- Engineering works that do not affect the listed building itself
Different tests, different decisions
Planning applications are decided against the development plan and other material considerations under section 38(6) of the Planning and Compulsory Purchase Act 2004. Heritage harm is one consideration weighed against others, including housing need, design quality and amenity.
Listed building consent applications are decided under the statutory duty in section 16(2) of the 1990 Act, special regard to the desirability of preserving the building, its setting and any features of special interest. The NPPF heritage paragraphs (200–214) apply to both consents but bite differently: in LBC, the heritage harm is the central question; in planning, it is one consideration among many.
Submitting in parallel
Where both consents are needed, they are usually submitted in parallel as separate applications with overlapping documents. The same heritage statement, drawings and photographs typically support both, with a separate planning statement addressing the planning balance. Validation, consultation and determination run in parallel, although the decisions are formally separate.
FAQs
Is listed building consent the same as planning permission?
No. They are two separate statutory consents under different Acts. Listed building consent is required under the Planning (Listed Buildings and Conservation Areas) Act 1990; planning permission under the Town and Country Planning Act 1990. Many works require both.
Do I need planning permission for internal alterations to a listed building?
Usually not, but you almost certainly need listed building consent. Planning permission generally responds to external change and use; LBC catches works affecting the special interest, internal or external.
Can a council grant planning permission but refuse listed building consent?
Yes. The two consents are determined separately and can produce different outcomes. A scheme that is acceptable in planning terms may still cause unjustified harm to a listed building's significance and be refused LBC.
