Conservation areas, listed buildings, flood zones, Article 4 directions, green belt, TPOs, local plans, title boundaries, and many other planning datasets, served via planning.data.gov.uk.

INSPIRE Index Polygons — registered freehold title boundaries for England and Wales. We host our own copy, refreshed monthly from HMLR's official monthly drop, and serve it through our own API.

Note

Title boundary data is indicative only and does not constitute a legal property boundary. Leasehold parcels and unregistered land are not included. Verify with HM Land Registry for any legally-binding decision.

Corporate ownership data — CCOD (UK companies and other corporate bodies) and OCOD (overseas companies) — for property in England and Wales, used in paid ownership features. Shown at postcode-district level only (proprietor name, country of incorporation, proprietorship category, title counts); we do not publish property addresses. The data month is displayed wherever ownership appears; the data is a monthly snapshot and can lag actual transactions.

This data is licensed to us, not open. Conditions flow down to you as an end user through our Terms: no redistribution of the data as a standalone dataset or product, no direct marketing to registered proprietors, no sub-licensing. It is a screening indicator only — not proof of ownership and not an official copy of the register.

The Welsh historic environment: listed buildings, conservation areas, scheduled monuments and their constraint areas, World Heritage Sites and essential settings, registered parks and gardens, registered historic landscapes, and protected wreck sites. Served from the DataMapWales GeoServer.

Note

Cadw, not Historic England, designates and maintains the list in Wales; the register is Cof Cymru. Grades (I, II*, II) are the same instrument under different administration.

Welsh designations and water: SSSIs, SACs, SPAs, Ramsar sites, National Nature Reserves, Local Nature Reserves, National Parks, AONBs, Heritage Coast and the Ancient Woodland Inventory 2021; the TAN15 Flood Map for Planning (rivers and sea, and surface water), TAN15 defended zones, the historic flood map, statutory main rivers, groundwater source protection zones, and the phosphate-sensitive SAC freshwater catchments. Served from the DataMapWales GeoServer.

Note

NRW is the Welsh counterpart of Natural England, the Environment Agency and the Forestry Commission combined, which is why one licence covers designations, flood and water. Its flood product is the Flood Map for Planning that TAN15 has worked from since 31 March 2025 — the Development Advice Map and its zones A, B, C1 and C2 are retired.

Predictive Agricultural Land Classification, Air Quality Management Areas, the CNOSSOS Round 4 road, rail and industrial noise grids, and unitary authority boundaries. Served from the DataMapWales GeoServer.

Note

The DataMapWales service states Fees: NONE and AccessConstraints: NONE. The Welsh noise mapping covers all roads and railways — wider than Defra's England mapping, which covers major routes only — and Wales publishes an industrial noise grid that has no English equivalent. The disused coal tip register is held on a separate "Varied / Derived" licence and is not used in this product.

The Scottish historic environment: listed buildings (categories A, B and C) and their mapped outlines, scheduled monuments, the national conservation-areas layer, gardens and designed landscapes, the Inventory of Historic Battlefields, Historic Marine Protected Areas, and World Heritage Sites with their buffer zones. Served from the HES INSPIRE server.

“Contains Historic Environment Scotland and Ordnance Survey data © Historic Environment Scotland – Scottish Charity No. SC045925 © Crown copyright and database right 2026”

Note

HES designates and maintains the Scottish list; categories A, B and C are the same instrument as England’s I, II* and II under different administration. Scheduled monument consent in Scotland is granted by HES itself, not by the planning authority and not by Scottish Ministers. The Ordnance Survey clause is required because HES digitises its designation boundaries against OS mapping.

Scottish designations: SSSIs, Special Areas of Conservation, Special Protection Areas, Ramsar sites, National Nature Reserves, Local Nature Reserves, the Ancient Woodland Inventory, Wild Land Areas 2014, and the class 1–2 extent of the Carbon and Peatland 2016 map.

Note

The Carbon and Peatland layer is co-produced with the James Hutton Institute and carries their credit alongside NatureScot’s. Only the Wind Farm Spatial Framework publication of that map — the class 1–2 extent — is OGL and used here; the fuller classification is published under the UK Non-Commercial Government Licence and is not used in this product. Wild Land Areas are not a statutory designation, but NPF4 policy 4 gives them significant weight.

Scottish flood and water: river, coastal and surface-water flood likelihood (high, medium and low), the Future Flood Maps climate-change extent, Drinking Water Protected Areas for groundwater, and the CNOSSOS Round 4 road, rail and industrial noise grids.

“© SEPA 2026. This SEPA product is licensed under the Open Government Licence v3.0”

Note

SEPA publishes flood **likelihood**, not England’s Flood Zone 2 and 3 and not Wales’s TAN15 zones: high is roughly a 1-in-10-year return period, medium 1-in-200, low 1-in-1000. Scotland has no Source Protection Zones either — the Drinking Water Protected Area is the Water Framework Directive designation and is labelled as such throughout. SEPA’s live Floodline warnings feed is key-gated and is not used.

Scottish council-supplied policy layers: green belt, Tree Preservation Orders (areas and individual trees), Article 4 directions, vacant and derelict land, and Air Quality Management Areas.

“Published under a UK Open Government Licence (OGL) v3.0. This dataset was amalgamated, optimised and published by the Improvement Service Spatial Hub using data provided by Scottish Local Authorities”

Note

These layers hold only what councils have chosen to supply — between four and thirty-two of the thirty-two, depending on the layer. Where the planning authority for a site has supplied nothing, this product reports that in as many words rather than reporting the site as clear of the designation. The covered-authority lists are derived from the data itself and re-checked on every verification run.

Note

There are thirty-four Scottish planning authorities, not thirty-two: the Cairngorms and Loch Lomond and The Trossachs National Park authorities are the planning authority inside their boundaries. National Scenic Areas are the Scottish analogue of an AONB. The James Hutton Institute’s Land Capability for Agriculture and the Prime Agricultural Land layer derived from it are not used: their licence text has not been obtainable.

Straight-line distance only — not catchment or admissions data. School admission depends on each school's and the local authority's own criteria, which change each year.

Postcode district names, centroids and population figures — derived from the ONS Postcode Directory and OS Code-Point Open — used to generate the per-district area pages under /area. We host our own copy, refreshed periodically from Doogal's postcode districts download.
