What counts as a listed building?

A building of special architectural or historic interest, designated by statute. The listing protects the whole building, including its interior and any structures within its curtilage.

Which nations are covered?

All four. England, Scotland, Wales and Northern Ireland, taken from four separate national registers and reconciled into one schema with a single stable id per building.

How are the different grade systems handled?

We keep them distinct. Historic England uses I, II* and II. Scotland uses A, B and C. Cadw uses the same I, II* and II labels as England. Northern Ireland uses A, B+, B1 and B2. They are mapped into one closed listed_grade vocabulary that preserves each nation's meaning, so grades are never falsely equated across borders.

Open Government Licence v3.0 throughout. The product deliberately excludes non-OGL sources, and per-custodian attribution is returned on every record, so commercial reuse stays clean.

Is the geometry polygons or points?

England is supplied as polygons. Scotland, Wales and Northern Ireland are largely point references. Every feature carries valid EPSG:4326 geometry, reprojected server-side from each source's native grid.

How do I link a listed building to a property?

Where a building can be matched to a property, the record includes a UPRN, which you can join to your own address records. Query the data by point, radius, bounding box or polygon, or fetch a single building by its stable id over REST.

Overview

About this dataset

A listed building is protected for its special architectural or historic interest. The listing covers the whole building, including its interior and any structures within its curtilage. This dataset holds 472,342 listed buildings across England, Scotland, Wales and Northern Ireland in one schema.

Listing is a statutory designation. England and Wales sit under the Planning (Listed Buildings and Conservation Areas) Act 1990 s.1, Scotland under the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997, and Northern Ireland under the Planning Act (Northern Ireland) 2011. We take the register from each named custodian: Historic England's National Heritage List for England, Historic Environment Scotland, Cadw via DataMapWales, and the Department for Communities Historic Environment Division.

Each nation grades differently and we do not pretend otherwise. Historic England uses I, II* and II. Scotland uses categories A, B and C. Cadw uses the same I, II* and II labels as England. Northern Ireland uses A, B+, B1 and B2. We map all of them into one closed listed_grade vocabulary that keeps each meaning intact, so a Scottish category B is never served as an English Grade II. Welsh records carry their bilingual name.

Query by point, radius, bounding box or polygon, or fetch one building by its stable id over REST. England is supplied as polygons. Scotland, Wales and Northern Ireland are point references. Every record carries valid EPSG:4326 geometry, the source URL, and per-custodian attribution under the Open Government Licence v3.0. Where a building matches a property, the record links to its UPRN.

What's included

Everything in the box

Four registers, one schema

England, Scotland, Wales and Northern Ireland reconciled into a single record shape, with one stable id per building.

Grades kept honest

A closed listed_grade vocabulary preserves each nation's grades. A Scottish category B is never equated with an English Grade II.

Spatial query built in

Query by point, radius, bounding box or polygon. England arrives as polygons, Scotland, Wales and NI as point references, all in EPSG:4326.

Clean OGL provenance

Every record is sourced from a named public custodian under the Open Government Licence v3.0, with per-custodian attribution returned inline.

Bilingual Welsh names

Welsh records carry name_cy alongside the English name, taken from Cadw via DataMapWales.

Links to property

Where a listed building matches a property, the record carries its UPRN so you can join it to your own address data.

Data fields

What each record carries

schema14 fields

reference: string// The building's native reference in its national register.

nation: enum// The UK nation the building sits in: ENG, SCO, WAL or NIR.

source: string// The named public custodian that maintains the record.

name: string// The listed building's name as recorded by the custodian.

name_cy: string// The Welsh-language name, present on Welsh records.

designation_type: string// The designation type for this product.

listed_grade: enum// Harmonised grade from a closed vocabulary that preserves each nation's meaning and is never equated across nations.

Use cases

What people build with it

Site due diligence

Check whether a target site holds a listed building, and at what grade, before committing to a scheme that would need listed building consent.

Developers

Collateral and valuation risk

Flag listed status on a property at origination, since alterations and repairs to a listed building carry consent obligations that affect value and cost.

Lenders

Conveyancing checks

Confirm listed status and grade against the address for a property search, with the source URL and custodian attribution on every record.

Conveyancers

Planning constraint layers

Build a listed building constraint layer for an authority area using polygon and point geometry in EPSG:4326.

Planners

Survey scoping

Identify listed status and grade ahead of a building survey so the inspection accounts for protected fabric and curtilage structures.
