Listed buildings: what listing means for planning and works

 

A listed building is a building included on the National Heritage List for England because of its special architectural or historic interest. Listing is a statutory designation under the Planning (Listed Buildings and Conservation Areas) Act 1990.

Listing does not mean a building must remain unchanged forever. It means that alterations, extensions or demolition which would affect its character as a building of special architectural or historic interest require Listed Building Consent. Planning permission may also be required, depending on the development.

The protection normally extends to the whole listed building – inside and outside – and can also extend to attached objects and structures and certain pre-1st July 1948 structures within its curtilage. The exact extent of listing can be surprisingly fact-sensitive, so do not assume the list description is a complete inventory of everything protected.

 

What part of a listed building is protected?

 

The common misconception is that only the front elevation or the features mentioned in the list description are listed. Unless the list entry expressly says otherwise, the statutory listing normally protects the whole building, including its interior and later additions.

Section 1(5) of the 1990 Act also brings within the meaning of the listed building:

• objects or structures fixed to the building; and
• objects or structures within the building’s curtilage which form part of the land and have done so since before 1st July 1948.

Modern list entries can use section 1(5A) to state expressly that specified attached or curtilage structures, objects, features or parts are not to be treated as part of the listed building, or are not of special interest. Always read the current National Heritage List entry as well as the older description.

 

Curtilage listing is not just an age test

 

A structure does not become curtilage listed simply because it is old and stands somewhere on the same property.

The statutory requirements include being within the curtilage, forming part of the land and having done so since before 1st July 1948. Whether land or a structure is within the curtilage is highly fact-specific. Historic England’s 2025 Advice Note 10: Listed Buildings and Curtilage identifies three useful starting factors drawn from the case law:

• the physical layout of the principal listed building and the structure
• their ownership, historically and at the relevant time
• their past and present use or function

R (Egerton) v Taunton Deane Borough Council [2008] EWHC 2752 (Admin) is a useful application of those factors to a farmstead. Sullivan J held that curtilage was a question of fact and upheld the conclusion that Mill Barn was outside the farmhouse curtilage where the physical layout showed a clear separation and the agricultural buildings were functionally distinct, despite common ownership at the relevant date.

The Court of Appeal revisited the wider concept in Blackbushe Airport Ltd v Hampshire County Council [2021] EWCA Civ 398. It confirmed that curtilage is a single concept across statutory contexts and that the core question is whether the land is so intimately associated with the building that it can properly be regarded as part and parcel of it. Functional convenience or being part of the same wider operational unit is not enough on its own.

Those factors are not an exhaustive formula. Farms, estates and former institutional or industrial sites can create difficult curtilage questions, especially where ownership or functional relationships have changed over time.

 

When is Listed Building Consent required?

 

Section 7 of the 1990 Act is the key provision. Consent is required for works for the demolition of a listed building or for its alteration or extension in a manner which would affect its character as a building of special architectural or historic interest.

That is why there is no reliable national list saying that every repair, repainting job or internal alteration always needs consent. The legal question is whether the proposed works fall within section 7 and affect the building’s protected character.

Works which can require LBC include changes to historic windows, doors, fireplaces, staircases, roofs, internal partitions, plasterwork, joinery or other fabric; extensions; substantial repairs which alter character; and demolition. Modern fabric can also matter where changing it would affect the character of the listed building as a whole.

If there is genuine uncertainty about proposed works, a Certificate of Lawfulness of Proposed Works can provide a statutory route to establish that the works described would not affect the building’s character and therefore do not require LBC.

 

Listed Building Consent and planning permission are separate

 

Listed Building Consent is not the same thing as planning permission. A project may need:

• only Listed Building Consent
• only planning permission
• both permissions
• neither, depending on the works

For example, an internal alteration may not amount to development requiring planning permission but can still require LBC. Conversely, development within the setting of a listed building can require planning permission without involving any works to the listed building itself.

Our detailed Listed Building Consent page explains the application process and the criminal consequences of unauthorised works.

 

What about permitted development?

 

The General Permitted Development Order grants planning permission for certain classes of development. It does not grant Listed Building Consent.

A planning operation may therefore benefit from permitted development rights but still be unlawful if it involves works to a listed building which require LBC. In addition, many GPDO classes expressly restrict development to, on or within the curtilage of listed buildings.

The safe approach is to ask two separate questions: does the development need planning permission? and do the works require Listed Building Consent? Our guide to permitted development and listed buildings deals with the common GPDO issues.

 

Grades of listed building

 

Listed buildings in England are divided into three grades:

• Grade I – buildings of exceptional interest
• Grade II* – particularly important buildings of more than special interest
• Grade II – buildings of special interest

The great majority are Grade II. Grade affects the recognised level of significance, but all three grades are statutory listed buildings and section 7 applies to them.

Under the August 2026 NPPF, Grade I and Grade II* listed buildings are expressly among the assets of the highest significance. Substantial harm or total loss to those assets should be wholly exceptional, while the same level of harm to a Grade II listed building should be exceptional.

 

How does the August 2026 NPPF treat listed buildings?

 

The current national heritage framework is set out in policies HE4 to HE6. The detailed planning balance is explained on our heritage significance and harm page.

In summary, heritage assets should be conserved in a manner appropriate to their significance. HE5 requires a proportionate assessment of significance and the potential effect of development. HE6 requires substantial weight to be given to conservation, with greater weight for more important assets, and says any harm to a designated heritage asset is a matter of considerable importance and weight.

A proposal which would have a positive effect should be supported. Harm must be clearly justified and weighed under the current HE6 framework.

 

The statutory duties: sections 16 and 66

 

National policy does not replace the statutory duties in the 1990 Act.

When determining an application for Listed Building Consent, section 16(2) requires the decision-maker to have special regard to the desirability of preserving the listed building, its setting and features of special architectural or historic interest.

When considering planning permission for development which affects a listed building or its setting, section 66(1) similarly requires special regard to the desirability of preserving the building, its setting and its features of special interest.

The Court of Appeal in Barnwell Manor Wind Energy Ltd v East Northamptonshire District Council & Others [2014] EWCA Civ 137 confirmed the importance of giving the statutory objective of preservation considerable importance and weight in the planning balance.

Jones v Mordue [2015] EWCA Civ 1243 later clarified the reasons issue: a decision-maker does not have to recite section 66 mechanically. Where the reasoning shows that the relevant heritage policies have been properly worked through, compliance with the statutory duty can be inferred unless the decision contains a positive indication to the contrary.

 

The setting of a listed building can extend beyond its boundary

 

Listing protects the building and qualifying curtilage structures, but planning can also protect the contribution made by its setting. Setting is the surroundings in which the heritage asset is experienced and is not confined to ownership, curtilage or a fixed-distance buffer.

The Court of Appeal’s decision in Catesby Estates Ltd v Steer [2018] EWCA Civ 1697 is particularly useful on this distinction. See our full guide to the setting of a heritage asset.

 

How do buildings become listed?

 

The Secretary of State for Culture, Media and Sport compiles the statutory list, with Historic England providing expert advice. Selection takes account of special architectural or historic interest, and the criteria become increasingly selective for more recent buildings.

The National Heritage List covers far more than houses and churches. It includes industrial buildings, bridges, walls, milestones, monuments and many other structures which fall within the statutory concept of a building.

If a building is not nationally listed but has genuine local heritage significance, it may instead be a non-designated heritage asset or locally listed building. That is a different planning status and does not create a separate Listed Building Consent regime.

A Certificate of Immunity from Listing can be relevant where certainty is required during a development proposal and there is a realistic risk of a building being listed.
