Why Checking Matters

If you carry out work that falls within a class of PD rights that has been removed by an A4D, you will have carried out development without planning permission. This is an enforcement risk. The LPA can issue an enforcement notice requiring you to reverse the works, and any sale of the property may be complicated by the breach.

Before starting any PD works — particularly in or near a conservation area, an HMO management area, or an area your LPA has listed as subject to directions — confirm whether an A4D applies to your specific address.

Method 1: LPA Website

This is the fastest starting point. Most LPAs publish:

• A list or schedule of current A4Ds, with dates and the rights removed.
• An interactive GIS map showing the boundaries of each direction.
• PDFs of the A4D notices themselves, showing the exact legal wording and schedule of removed classes.

Search for “[your council name] Article 4 Direction” or look under the Planning Policy or Planning Enforcement sections of the LPA’s site. Many councils also include A4D information in their adopted Local Plans.

Method 2: Planning Portal

The Planning Portal offers a property search that returns basic information about the planning history and designations affecting an address, including whether it is in a conservation area. However, the Portal does not always return full details of site-specific A4Ds — it is a useful first check but not definitive.

Method 3: Local Land Charges Register

Article 4 Directions are registerable as local land charges under the Local Land Charges Act 1975. Searching the Local Land Charges Register (LLC1 search) will reveal any A4Ds registered against the property.

You can access this:

• Via GOV.UK’s Digital Local Land Charges service, which is progressively being rolled out across LPAs. Where available, an official search can be obtained instantly online.
• Via the LPA directly (official search or personal search) for councils not yet migrated to the digital service.

An LLC1 search is the most legally authoritative method and is routinely carried out as part of conveyancing searches when buying a property.

Method 4: Pre-Application Enquiry

You can submit a pre-application enquiry to the LPA asking whether an A4D applies to your address and, if so, which rights are removed. Many councils offer a free or low-cost basic pre-application service. A written response provides the clearest confirmation and creates a record if any dispute later arises.

Area-Wide vs Site-Specific A4Ds

Area-wide A4Ds cover a defined geographic area — typically a conservation area, an Article 4 zone for HMOs, or a designated neighbourhood. All properties within the boundary are affected equally. These are the most common type and are usually easy to identify on the LPA’s GIS maps.

Site-specific A4Ds target individual properties or small groups of buildings. They may be made to protect a locally listed building, to prevent intensification of use at a specific site, or to address a known planning concern. Site-specific A4Ds may not always appear clearly on area maps — an LLC1 search is the safest way to identify these.

HMO Article 4 Directions

Since the introduction of Class L permitted development rights (C3 to C4 HMO conversion), many LPAs have made A4Ds removing those rights across parts or all of their area. These are often borough-wide or cover specific wards with high concentrations of HMOs.

Key areas with borough-wide or near-borough-wide Class L A4Ds include many London boroughs (including Camden, Islington, Southwark, and Newham), Oxford, Cambridge, Bristol, Leeds, and several other university cities and towns.
