Listed Building Checker UK

Check consent requirements for works to listed buildings. Understand listing grades, penalties and what needs approval — free. Unlock application checklist, heritage statement outline and PDF for £7.99 one-off.

If your property is listed, you will need Listed Building Consent for most alterations — and that applies to internal works as well as external changes. Even seemingly minor jobs like replacing windows, removing an internal wall, or fitting a new kitchen can require formal approval if they affect the building's character.

Listings are graded. Grade I buildings are of exceptional interest, Grade II* are particularly important, and Grade II covers the vast majority. The grade affects the level of scrutiny your application receives, but all grades carry the same legal protection. Carrying out unauthorised work to a listed building is a criminal offence that can result in unlimited fines or imprisonment.

Historic England's National Heritage List records approximately 400,000 listed buildings in England alone (Historic England). If you are unsure whether your property is listed, this tool checks official planning constraint data by postcode.

Grade I

Exceptional interest

Buildings of exceptional interest. Only 2.5% of listed buildings are Grade I. These are of the highest significance and the most tightly controlled. Any proposed work faces intense scrutiny.

approx. 9,500 in England

Grade II*

Particularly important

Particularly important buildings of more than special interest. About 5.8% of listed buildings are Grade II*. Works require the same consent process but applications are reviewed with greater care.

approx. 22,000 in England

Grade II

Special interest

Buildings of special interest, warranting every effort to preserve them. The vast majority (91.7%) of listed buildings are Grade II. Consent is still required for alterations but there is generally more flexibility than higher grades.

Frequently asked questions

What is a listed building?▾
A listed building is one that has been placed on the Statutory List of Buildings of Special Architectural or Historic Interest by the Secretary of State. Listing covers the entire building, inside and out, plus any structures within its curtilage (boundary) that predate July 1948. There are approximately 380,000 listed buildings in England.
Do I need Listed Building Consent for internal works?▾
Yes. Unlike standard planning permission, Listed Building Consent is required for internal alterations that affect the character of the building. This includes removing or altering period features, changing room layouts, modifying staircases, and altering fireplaces. Even minor works like installing new electrical wiring routes may require consent.
What happens if I do work without consent?▾
Carrying out unauthorised works to a listed building is a criminal offence under Section 9 of the Planning (Listed Buildings and Conservation Areas) Act 1990. Penalties include unlimited fines and up to 2 years imprisonment. The local authority can also issue an enforcement notice requiring you to reverse the work at your own cost.
Is Listed Building Consent the same as planning permission?▾
No. They are separate applications to the local authority. Some works (like extensions) may need both Listed Building Consent AND planning permission. Others (like internal alterations) may only need Listed Building Consent. The two applications run in parallel but are assessed under different legislation.
How long does Listed Building Consent take?▾
The statutory determination period is 8 weeks for straightforward applications or 13 weeks for major applications. However, Grade I and Grade II* applications must also be referred to Historic England, which adds time. In practice, many applications take 10-16 weeks. Pre-application consultation can help speed up the formal process.
Can I replace windows in a listed building?▾
Window replacement almost always requires Listed Building Consent. Like-for-like repair of existing windows using identical materials and methods may be acceptable. However, replacing timber windows with uPVC is very likely to be refused. Secondary glazing (internal) is often an acceptable alternative for improving thermal performance.
Do I need a heritage statement?▾
Yes. All Listed Building Consent applications must include a Heritage Impact Assessment (also called a heritage statement). This describes the significance of the building, the proposed works, and their impact on that significance. For complex proposals, you may need to commission this from a heritage consultant.
Can a listed building be demolished?▾
Demolition of a listed building requires Listed Building Consent and is only granted in exceptional circumstances. You must demonstrate that all reasonable alternatives have been explored, that the building cannot be repaired or adapted, and that redevelopment would bring substantial benefits. Total demolition is extremely rarely approved.
Does listing affect the value of a property?▾
Listing can affect property value both positively and negatively. The prestige and character of a listed building can command a premium, particularly in desirable areas. However, the additional costs of maintenance using traditional materials, and restrictions on alterations, can deter some buyers. Overall impact depends on the specific property and market.
How do I check if my building is listed?▾
Search the National Heritage List for England at historicengland.org.uk/listing/the-list. For Wales, check Cadw. For Scotland, check Historic Environment Scotland. The listing entry includes the grade, date of listing, and a description of the building special interest. Your local authority conservation officer can also advise.
