UK Listed Building Data

The WRENN Report aims to assemble every public dataset that touches a UK listed building. That includes the registers themselves, planning applications, Energy Performance Certificates, Land Registry sale prices, flood and radon risk and more, linked together at the building level.

Listed buildings — all four nations

493,181 listed buildings, collected from the official heritage registers of all four UK nations and consolidated into a single search interface.

• England — 379,840 buildings (Historic England)
• Scotland — 67,463 buildings (Historic Environment Scotland)
• Wales — 30,116 buildings (Cadw)
• Northern Ireland — 15,762 buildings (NIEA)

By statutory grade: Grade I (16,407) · Grade II* (59,665) · Grade II (399,120). Buildings span 379 Local Planning Authorities.

Almost all buildings have had their official register entry rewritten into “clean” English for clarity, while preserving all factual content. The original register text is also retained.

Planning applications and Listed Building Consent

893,402 listed building consent applications, ingested daily from PlanIt and WRENN’s own systems. 223,879 buildings (45%) have at least one matched application linked to them. Matching uses a multi-stage address pipeline to maximise the percentage of listed building consents correctly attributed.

Every application has been processed to extract structured “physical attribute” tags to enable you to search based on the type of work to which the application refers.

Energy Performance Certificates

Domestic EPCs from the Department for Levelling Up, Housing & Communities (England & Wales) and statistics.gov.scot (Scotland), plus non-domestic EPCs covering pubs, churches, museums, schools, and offices. Refreshed monthly (E&W) and quarterly (Scotland).

128,302 listed buildings have at least one EPC matched to them. Listed buildings skew strongly toward the lower energy bands: D and E are most common, only ~1.6% are rated B or above (versus ~15% nationally), and ~7% are rated G. More statistics are available on the Stats & Indices page.

Northern Ireland is not currently covered for EPC. The data is not published as open data and would require an EIR request to the Department of Finance.

HM Land Registry sale prices

Residential property transactions in England & Wales from January 1995 onwards, from HM Land Registry’s Price Paid Data (Open Government Licence). 146,849 listed buildings have at least one sale matched to them — multiple sales per building are preserved to expose a full price history. Again, statistics are available on the Stats & Indices page.

Environmental risk

Every building (where the underlying flood/radon data is openly licensed) has a flood-zone classification and a radon-risk classification:

• Flood (477,419 buildings) — Environment Agency Flood Map for Planning (England), Natural Resources Wales (Wales), SEPA v3 Flood Maps (Scotland). Northern Ireland data is commercially licensed and not included.
• Radon (493,159 buildings) — BGS/UKHSA Indicative Atlas of Radon (Great Britain) and BGS/GSNI atlas (Northern Ireland). Six-band classification from “< 1%” to “> 30%” probability.

Architect and historical-figure attributions

63,044 buildings (13%) have at least one named architect, designer, builder, or historical figure extracted from the register description. Names have been “standardised” to merge common variants (e.g. “Sir Christopher Wren” / “Christopher Wren”). 31,538 distinct names are captured in total.

The most-frequent attributions in the dataset:

• Sir Giles Gilbert Scott — 2,180 buildings
• Sir Edwin Lutyens — 403 buildings
• William Burn — 296 buildings
• Sir George Gilbert Scott — 282 buildings
• William Butterfield — 279 buildings
• Thomas Telford — 270 buildings
• G.E. Street — 270 buildings
• John Carr — 248 buildings

How to explore

• Search buildings — by name, attributes, location, grade, type, period, style, material, or architect.
• Search applications — by LPA, decision status, date, or extracted physical-attribute tag.
• Stats & Indices — visualised national-level breakdowns of the dataset.
• Or follow links into one of the country indexes above to browse by Local Planning Authority.

Licence and attribution

Source data is reused under the licences of its original publishers:

• Listed building registers — Crown Copyright / Open Government Licence v3.0 (Historic England, HES, Cadw) and Crown Copyright (NIEA).
• Planning data — sourced via PlanIt.org.uk, originating from individual UK Local Planning Authority portals.
• EPC Register — Open Government Licence v3.0 (DLUHC and statistics.gov.scot).
• HM Land Registry Price Paid Data — Open Government Licence v3.0.
• Flood and radon data — Open Government Licence v3.0 / British Geological Survey licence terms as applicable.
• ONS Postcode Directory — Open Government Licence v3.0.

Aggregated, derived, and structured outputs published on this site (attribute tags, address matching, person-name standardisation, rewritten descriptions and all linkages between data sources) are available for non-commercial research use. For commercial use or bulk data access, please get in touch.

Coverage gaps and known issues

Much is still missing or imperfect:

• Northern Ireland is not yet covered for EPCs (no open data) or for flood risk (commercially licensed data only).
• PlanIt’s decision-feed is patchy: applications are captured reliably but decision dates and outcomes can be delayed or missing on individual records. We use multiple decision-state fields to compensate, and are superseding PlanIt with our own tools in some LPAs.
• Architect attributions can occasionally pick up bibliographic mentions or witness names rather than architects themselves.

Needless to say, we are trying to improve all the time.
