Listed Buildings: What Needs Consent and What Doesn’t (2025)
Listed building consent is required for any works that affect the character of a listed building — but the rules are more nuanced than a blanket prohibition. Here’s what you can and can’t do.
Quick Answer
Listed building consent required for most internal and external works
A listed building is protected under the Planning (Listed Buildings and Conservation Areas) Act 1990. Listed building consent (LBC) is required for any works that would affect the character of the building as a building of special architectural or historic interest — including most internal alterations, external alterations, and works within the curtilage. Permitted development rights under the GPDO 2015 are significantly restricted for listed buildings: many PD rights that apply to ordinary houses simply don’t apply to listed buildings. Extensions, outbuildings, and many other works that would be PD for a normal house require both planning permission and listed building consent for a listed building.
What Is a Listed Building?
A listed building is a building, structure, or object included on the National Heritage List for England (NHLE) because of its special architectural or historic interest. There are approximately 400,000 listed buildings in England.
Listed buildings are classified in three grades:
- Grade I: Buildings of exceptional interest (around 2% of all listed buildings)
- Grade II*: Particularly important buildings of more than special interest (around 6%)
- Grade II: Nationally important and of special interest (around 92%)
All three grades carry the same legal protections — the grade affects how Historic England and councils approach consent applications, not whether consent is required.
When Is Listed Building Consent Required?
Listed building consent is required for works that would affect the character of the listed building as a building of special architectural or historic interest. This is a broad test and covers:
- External alterations: Replacing windows, changing doors, re-roofing, re-pointing, cladding, painting (where paint has not previously been used)
- Internal alterations: Removing walls, altering fireplaces, removing period features (panelling, cornices, staircases), changing floor finishes
- Extensions: Any extension to a listed building requires LBC (and usually planning permission)
- Outbuildings and structures: Any structure within the curtilage of the listed building may require LBC if it affects the setting
- Demolition: Any demolition of a listed building or part of it
Permitted Development Rights for Listed Buildings
Most of the permitted development rights that apply to ordinary houses do not apply to listed buildings. The GPDO 2015 explicitly excludes listed buildings from many PD classes:
| PD class | Applies to listed buildings? |
|---|---|
| Part 1 Class A (rear extensions) | No — planning permission needed |
| Part 1 Class B (roof alterations) | No — planning permission needed |
| Part 1 Class C (roof coverings) | No — LBC required |
| Part 1 Class D (porches) | No — planning permission needed |
| Part 1 Class E (outbuildings) | No — planning permission needed |
| Part 2 Class A (gates, fences, walls) | No — planning permission needed |
| Part 2 Class C (painting) | Not applicable where painting affects character |
In practice, most works that would be PD for a non-listed house require both planning permission and listed building consent for a listed building.
What Doesn’t Need Consent
Some works to listed buildings don’t require consent:
- Like-for-like repairs: Repairing the building using the same materials and methods (replacing a rotten timber window with an identical timber window, re-pointing with lime mortar to match the original) is generally considered maintenance rather than alteration
- Decoration: Decorating rooms with paint (where the building has previously been painted internally) is generally not development
- Non-intrusive work to unlisted structures: Work to clearly modern structures within the curtilage that have no connection to the historic building may not require LBC
How to Apply for Listed Building Consent
Listed building consent applications are made to the local planning authority, usually alongside a planning application where one is also needed. LBC applications are free of charge. The council has 8 weeks to determine the application. For significant works, Historic England is a statutory consultee.
A well-prepared application typically includes existing and proposed drawings, a heritage statement explaining how the works preserve or enhance the significance of the building, and a method statement for the proposed works (materials, fixings, reversibility).
Conservation officers value reversibility — works that can be undone without damaging the fabric of the building are looked on more favourably. Where modern interventions are needed (damp-proofing, insulation), breathable and reversible methods are preferred over impermeable modern materials.
