If you own property in England, there may be a legal restriction affecting what you can do with it — and you'd have no way of knowing.
Article 4 Directions are one of the most powerful planning tools available to local authorities. They remove permitted development rights, meaning work that would ordinarily be allowed without planning permission suddenly requires a full application. Extensions, conversions, changes of use, alterations to appearance — all can be restricted by an Article 4 Direction.
What Is an Article 4 Direction?
Permitted development rights allow homeowners and developers to carry out certain works without needing to apply for planning permission. Article 4 Directions remove those rights in a specific area. Common examples include conservation areas where local authorities want to control changes to windows, doors, and materials, and areas where landlords have been converting family homes into houses of multiple occupation (HMOs) at rates that local authorities consider damaging to community character.
Once an Article 4 Direction is in place, any work within its scope requires a full planning application. Doing the work without one is a planning breach, regardless of whether you knew the direction existed.
The Hidden Problem
The national planning data platform, planning.data.gov.uk, maintains a dataset of Article 4 Directions published by local authorities across England. It currently holds over 7,300 records. But that figure masks a significant gap: some authorities publish nothing at all.
One of the largest unitary authorities in England — formed following the merger of several predecessor district councils — publishes zero Article 4 records to the national platform. Not one. Yet Article 4 Directions are confirmed to exist across the former district areas, documented in the predecessor councils' own planning committee records before the merger. When those predecessor websites were taken down, the records went with them — and nothing replaced them.
The result is that residents, developers, and conveyancers searching the national platform for restrictions in these areas find nothing — and may conclude, incorrectly, that no restrictions exist.
A Real Case
In August 2026, a parish council chair contacted LandLens® with a specific problem. The parish had been informed that an Article 4 Direction existed for their conservation area — but despite searching every available online source, nothing could be found.
LandLens® traced the direction through archived predecessor council planning records. Two separate archived web pages confirmed the existence of the direction, including a direct link to the order document — a PDF that had been hosted on the predecessor council's website before it was taken down. The document was never captured by any web archive.
The direction is real. It appears in the predecessor council's own register. But because the successor authority has not published it to planning.data.gov.uk or to its own website, it is effectively invisible to anyone who doesn't know exactly where to look and how to ask.
What You Can Do
If you are buying, developing, or advising on property in England, particularly in areas that have undergone local authority mergers, do not rely solely on the national planning data platform to confirm the absence of Article 4 Directions.
The most reliable route is a formal Environmental Information Regulations (EIR) request to the relevant local authority, citing the specific area and requesting confirmation of any directions in force. Article 4 Directions are also registrable as Local Land Charges, meaning an LLC1 search on any property within the affected area should reveal them.
LandLens® checks Article 4 data from planning.data.gov.uk as part of every site constraint report. Where data gaps are identified, we flag them explicitly rather than returning a false negative. A clean result is only meaningful if the underlying data is complete.
The Broader Issue
This is not an isolated case. The inconsistency of planning data publication across English local authorities is a systemic problem. Councils have a duty to maintain planning records but no enforceable obligation to publish them in machine-readable form. Until that changes, the gap between what authorities hold and what the public can access will remain a risk for anyone making decisions based on publicly available planning data alone.
