Check what could affect a property project
Start with the official registers we can publish: listed buildings, conservation areas, tree protection and Article 4 directions. These checks are a signpost, not a local land-charge search or planning opinion.
Area
Conservation areas
10,662 published areas. Extra controls may affect demolition, extensions, windows and trees.
Permitted development
Article 4 directions
8,005 published directions. These can remove rights that would otherwise avoid a full application.
Garden and site
Protected trees
101,726 published tree-protection zones. Work to a protected tree may require consent.
Evidence found
The current site snapshot contains 521,034 statutory-designation records across the available planning.data.gov.uk registers.
Source coverage
Local-authority contribution to the national registers is uneven. The source snapshot records coverage for 2,159 postcode districts, but coverage varies by designation type and by authority.
What this means
A matched record is a useful official signpost to investigate before design or purchase decisions.
What this does not mean
No match does not prove that a property is unconstrained. It can mean the authority has not supplied that register, the current snapshot has no match, or the project needs a property-level legal search.
Planning applications remain held
The held R2 catalogue includes planning-application data, but the Greater London Authority and council source families do not yet have a complete publication-rights record. Application descriptions, addresses and decisions are therefore not exposed on the live site.
Next step
Need help interpreting the result?
Ask for an introduction to a planning consultant, architect, surveyor, conveyancer or tradesperson. Property facts stay independent of any commercial introduction.
