Listed building consent or planning permission: which applies

Listed building consent and planning permission are separate consents under separate Acts, and a scheme on a listed building very often needs both. Planning permission controls development, meaning building operations and material changes of use under section 55 of the Town and Country Planning Act 1990. Listed building consent controls works of demolition, alteration or extension that affect the character of the building as one of special architectural or historic interest, under section 7 of the Planning (Listed Buildings and Conservation Areas) Act 1990. The tests are different, the applications are different, and getting one does not give you the other.

Two consent regimes over one building

The practical difference is what each regime is looking at. Planning permission asks whether the development is acceptable in land use terms: scale, massing, amenity, highways, drainage, the effect on the wider area. Listed building consent asks a narrower and deeper question about the fabric and interest of the building itself.

A rear extension to a Grade II farmhouse needs both. Replacing a rotten sash window with an identical sash, using the same section and glazing, probably needs neither, because it is repair rather than alteration and it is not development. Replacing that sash with a uPVC casement of the same size needs listed building consent and no planning permission, because the external appearance of a dwellinghouse is altered but the work is not development requiring permission on a house of that kind.

That last example catches people out constantly. The work you can do without troubling the planning department is not the work you can do without troubling the conservation officer.

The duty under sections 16 and 66

Section 16(2) of the 1990 Act requires the authority, when deciding a listed building consent application, to have special regard to the desirability of preserving the building, its setting, and any features of special architectural or historic interest it possesses. Section 66(1) imposes the same duty when the authority decides a planning application for development that affects a listed building or its setting.

"Special regard" is not the ordinary planning balance. The Court of Appeal in Barnwell Manor Wind Energy Ltd v East Northamptonshire DC (2014) held that harm to a listed building or its setting must be given considerable importance and weight, and that a finding of harm creates a strong presumption against permission which the applicant has to overcome. National policy in the National Planning Policy Framework, current edition published on 17 August 2026, layers the less than substantial and substantial harm tests on top of that statutory duty.

So a scheme can be perfectly acceptable on massing, parking and drainage and still fail, because the heritage duty bites harder than the planning balance.

Works that need one, the other, or both

Two procedural points are worth knowing before you fill anything in. There is no application fee for listed building consent, which surprises most first-time applicants. And permitted development rights under the General Permitted Development Order 2015 are not removed by listing in every case, so you can hold a permitted development right and still need listed building consent for the same work.

Internal alterations and why they are caught

Section 7 catches works affecting the character of the building as a building of special interest, without any distinction between inside and out. Plan form, staircases, chimneypieces, cornices, panelling, floorboards, historic plaster and early joinery are all part of the special interest, and stripping them out is an alteration.

Listing is also whole-building. The list entry describes what the inspector saw, usually the exterior and the most obvious internal features, but the designation covers the entire structure. An entry that says nothing about the roof void does not mean the roof void is unlisted.

The routine casualties are chimney breast removal, opening up a front and back room into one, replacing lime plaster with gypsum, and inserting a bathroom into a principal first-floor room. Each of those needs consent, and each is regularly done without it.

Curtilage structures and the 1948 test

Section 1(5) of the 1990 Act extends listing to any object or structure within the curtilage of the listed building which has formed part of the land since before 1 July 1948. A pre-1948 coach house, stable block, garden wall or privy can therefore be listed in its own right without appearing anywhere in the list entry.

The courts apply a three-part test drawn from Attorney-General ex rel Sutcliffe v Calderdale Borough Council (1983): the physical layout of the building and the structure, their past and present ownership, and their past and present use or function. Skerritts of Nottingham Ltd v Secretary of State (2000) confirmed that curtilage is a question of fact and degree rather than a matter of the title plan.

This is the single most common gap in a heritage evidence base. Before you design anything involving an outbuilding, establish its date and its relationship to the principal building, and say so in your Heritage Statement. If the site also has archaeological potential, our comparison of a Heritage Statement and an Archaeological Desk-Based Assessment explains which document answers which question.

Unauthorised works and the criminal offence

Carrying out works to a listed building without consent is a criminal offence under section 9, not a planning breach. Conviction on indictment carries an unlimited fine and imprisonment of up to two years. The offence is one of strict liability in the sense that not knowing the building was listed is no defence, although section 9(3) provides a narrow defence for urgent works necessary in the interests of safety or health.

There is no immunity period. The four and ten year rules that apply to ordinary planning breaches do not apply here, so a listed building enforcement notice under section 38 can require reinstatement of work carried out decades ago.

Retrospective listed building consent is possible under section 8(3), and conservation officers do grant it where the work turns out to be acceptable. Relying on that is a poor plan.

One evidence base, two applications

The efficient way to run a listed building project is to prepare a single assessment of significance and then split it between the two applications. Historic England's advice on statements of heritage significance sets the expected structure: what the building is, why it matters, which parts carry the interest, how the proposal affects each of them, and what the residual harm is.

The planning application draws on that to answer section 66 and the wider development plan tests, supported by a Planning Statement and a Design and Access Statement. The listed building consent application draws on the same assessment to answer section 16, with drawings at a larger scale, a schedule of works room by room, and a specification for anything involving historic fabric.

Submit them together. Councils will usually validate and determine them in parallel, and a consent granted without its matching permission is worth very little.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.
