Planning history, in plain sight.

What the planning register actually contains

Section 69 of the Town and Country Planning Act 1990 places a duty on every local planning authority in England to maintain a register of all planning applications made in its area, together with the decisions taken on each. The register is a public document, available for inspection during normal office hours and — for the vast majority of LPAs — online via their planning portal (TCPA 1990, section 69).

The register records: the application reference number, the address, the description of the development proposed, the date of application, the decision (granted, refused, or withdrawn), any conditions attached to a grant, and the date of determination. For appeals, the Planning Inspectorate maintains a separate database of all appeal decisions (appeal type, inspector's decision, appeal date, and the reasoning in the decision letter).

Since 2021, the government has been publishing planning application data nationally through planning.data.gov.uk — a centralised dataset aggregating decisions from all LPAs that have contributed data. As of 2025, coverage across all English LPAs is substantial but not complete; Eavesdrop cross-references both the national dataset and the relevant LPA's own register to maximise coverage (DLUHC, planning.data.gov.uk, 2025).

How to find planning history for a UK property

The primary route is the local planning authority's public-facing search tool, accessible through the authority's website or through the Planning Portal (planningportal.co.uk), which aggregates links to all 337 LPAs in England. Search by full address or postcode. Most portals display the application reference, the description, and the decision; the full decision notice and any conditions can typically be downloaded as a PDF.

For historical applications decided before digital records were kept — generally pre-1990 for most LPAs — paper records may exist at the LPA offices. A solicitor's local search (conducted through the LLC1 and Con 29 forms) will reveal planning decisions affecting the property within the authority's records, including any outstanding enforcement notices, Article 4 directions, and Tree Preservation Orders (Land Charges Act 1975; Law of Property Act 1922).

Enforcement notices and breach of condition

Where development has taken place without permission, or in breach of planning conditions, the local planning authority may issue an enforcement notice under section 172 of the Town and Country Planning Act 1990. The notice specifies the breach, the steps required to remedy it, and the compliance period. A breach of condition notice may also be issued separately under section 187A (TCPA 1990, section 187A).

An outstanding enforcement notice is a registerable local land charge and must be disclosed in a solicitor's search. However, 'immune' breaches — those more than four years old for operational development, or more than ten years old for a change of use — can no longer be enforced (TCPA 1990, section 171B). Solicitors routinely advise buyers to obtain indemnity insurance for immune but undocumented breaches where retrospective planning permission cannot be obtained.

A planning enforcement notice that has not been complied with can affect mortgage availability. Some lenders will decline a property with an outstanding enforcement notice; others will lend subject to solicitor's advice that compliance is not required (e.g. on immunity grounds). Check with your broker before proceeding on any property where an active enforcement notice exists (UK Finance Lenders' Handbook, Part 1, section 5.10, 2024).

Article 4 directions — when permitted development is removed

Permitted development rights allow many common types of building work — single-storey extensions, loft conversions, outbuildings, certain changes of use — without the need for a planning application. These rights are defined in the Town and Country Planning (General Permitted Development) Order 2015 (GPDO 2015). However, a local planning authority may make an Article 4 direction to withdraw some or all of these rights from a defined area, requiring a planning application before work that would otherwise be permitted can proceed.

Article 4 directions are commonly used in conservation areas, historic town centres, and areas of high-density housing where the cumulative effect of permitted development is considered harmful. They can also be used to prevent the conversion of dwellings to Houses in Multiple Occupation (HMO) without consent. An Article 4 direction affecting your property may have a significant impact on what alterations you can make and whether future planning applications will be required (GPDO 2015, article 4).

Conservation areas and Listed Building Consent

Conservation areas are designated by local planning authorities under section 69 of the Planning (Listed Buildings and Conservation Areas) Act 1990. Within a conservation area, additional restrictions apply to permitted development — for example, permitted development rights for certain types of cladding or extensions may be withdrawn, and demolition of a building requires Conservation Area Consent (Planning (Listed Buildings and Conservation Areas) Act 1990, section 74).

A listed building is one included on the National Heritage List for England, maintained by Historic England. Listed buildings are graded Grade I (highest significance), Grade II*, or Grade II. Any works to a listed building that would affect its character require Listed Building Consent, separate from and additional to any planning permission required. Carrying out unauthorised works to a listed building is a criminal offence under section 7 of the 1990 Act, and the offence does not run the same limitation periods as planning enforcement (Planning (Listed Buildings and Conservation Areas) Act 1990, sections 7 and 9).

Pending applications and neighbouring development

A buyer's solicitor's local search (the Con 29 enquiry) reveals planning decisions already made — but it does not necessarily capture pending applications that have been submitted but not yet determined. A pending application for a large development on an adjacent site may not appear on a search result if it was submitted after the search date. Checking the LPA's online register directly at the time of exchange, rather than relying solely on search results from an earlier date, is advisable for any property where a significant neighbouring development would affect your decision (TCPA 1990, section 69).

The Planning Inspectorate's appeal database (appeals.planninginspectorate.gov.uk) also records all appeals against LPA decisions, and major infrastructure proposals are subject to separate National Infrastructure Planning through the Planning Inspectorate under the Planning Act 2008. Eavesdrop checks both sources as part of the planning history review.

What Eavesdrop checks for planning history

Every Eavesdrop report queries the following named public registers for the specific property address and UPRN:

• planning.data.gov.uk — the national planning decision dataset aggregated from contributing English LPAs, searched by UPRN and surrounding polygon
• Local authority planning register— the relevant LPA's public planning search, queried by address for the property and adjacent addresses
• Planning Inspectorate appeal database — appeal decisions related to the property address or UPRN
• Historic England National Heritage List — listed building status (grade and description) for the property
• Conservation area boundaries— from the local authority's published GIS data and the Historic England national conservation area dataset
• Article 4 direction register— LPA-published Article 4 directions in force for the property's location

Each result is presented with the register source, the date of the record, and the decision or designation status. No planning history data in the Eavesdrop report is produced by LLM inference — every result is a deterministic lookup from the named register.
