Checking whether an Article 4 direction applies to a property

To check article 4 direction coverage at a specific address, you need three things: the direction document itself, the map or schedule that defines the area it covers, and the date it came into force. A tick on a map layer is not enough. The direction is a legal instrument and its wording decides exactly which permitted development rights have gone, which is rarely the whole class and is sometimes only part of one.

This matters most to anyone converting a house to a small house in multiple occupation, where the right relied on is Class L of Part 3 of Schedule 2 to the General Permitted Development Order 2015, and where many authorities have removed it across whole wards.

Where directions are published

Start with the local planning authority's own website. Authorities are required to keep and publish a list of directions in force, usually under a heading such as article 4 directions or permitted development rights removed.

Then cross-check against the national planning data platform, which carries article 4 direction and article 4 direction area datasets contributed by authorities. It is useful and it is incomplete, because publication depends on each authority supplying and updating its data.

Where the two disagree, the authority's own document governs. The national dataset is a finding aid.

A third route is the local land charges search on the property, which should reveal a direction affecting it. That comes late in a purchase, which is precisely why it is worth doing the free checks first.

Reading the direction to see what has actually gone

Open the direction itself rather than the summary page. You are looking for four things.

• The classes and parts of Schedule 2 withdrawn, quoted exactly. A direction may remove Class A of Part 1 alone, or several classes, or a single class in part.
• The area, defined by a map, a schedule of streets, a schedule of addresses, or a combination.
• The date the direction was made, the date it was confirmed, and the date it took effect.
• Any exclusions written into it, such as listed buildings or a stated use.

Precision pays here. A householder direction removing Class A of Part 1 stops rear extensions under permitted development but leaves outbuildings under Class E alone unless the direction says otherwise. A direction aimed at shopfronts may remove only Class M of Part 3. Assuming a blanket removal leads to unnecessary applications, and assuming a narrow one leads to enforcement.

Boundaries and properties on the edge

Mapped areas and address schedules do not always agree, and the mapped line is often drawn at a scale that leaves individual properties ambiguous.

Where the property sits on or near the boundary, treat the position as unresolved until the authority confirms it in writing. Corner plots, properties with land extending beyond a defined line, and flats within a building that straddles a boundary are the recurring cases.

Ask the question in a form that produces a useful answer. Give the full address, the title number if you have it, a plan with the property outlined, the specific right you intend to rely on with its class and part, and the date you intend to rely on it. Then ask whether that right is withdrawn at that address. A vague enquiry produces a vague reply, and a vague reply protects nobody.

Confirmation dates and directions not yet in force

Timing decides whether a right still exists today.

Directions take effect in one of two ways. A direction can be made to come into force immediately, in which case it must be confirmed within a set period or it lapses. Alternatively, the authority gives at least 12 months notice before it takes effect, which avoids the compensation liability that can otherwise arise under section 108 of the Town and Country Planning Act 1990.

The practical consequence for an investor is a window. A direction announced with 12 months notice leaves a period in which the permitted development right still exists. Using it within that window is lawful, provided the development is genuinely begun and, where relevant, completed in accordance with the class conditions.

National policy asks authorities to limit directions to cases where they are necessary to avoid unacceptable impacts, and to apply them to the smallest area that will do the job. That does not stop wide directions being made, and it is not a reason to assume one will be narrow.

When the right has already been exercised

A direction does not undo development that was lawfully carried out before it came into force.

If the conversion, extension or change of use was completed while the right existed, it is lawful and stays lawful. The evidential burden is yours, though, and years later the file is what settles it. Keep dated photographs, invoices, tenancy agreements, council tax records and building control paperwork.

Where a use began before the direction and the position may be questioned, a lawful development certificate under section 191 of the Town and Country Planning Act 1990 is the formal way to put it beyond doubt. For a proposed use, section 192 does the same job in advance. That certificate is the only way to confirm the position with certainty, and it is worth its fee before a purchase or a refinancing.

Part-completed works are the difficult case. Whether a right has been implemented in time is fact-specific, and the answer usually needs advice rather than optimism.

An illustrative example. A landlord buys a three-bedroom terrace intending a five-bedroom small HMO, relying on Class L. The council made a direction covering the ward, confirmed it, and it took effect two months before completion of the purchase. The right has gone, so the route is a planning application addressing the concentration policy, and the purchase price should have reflected that. The dates here are illustrative.

Where a direction applies, and what follows

Losing the permitted development right does not mean the development is unacceptable. It means you apply for planning permission and the proposal is judged on its merits against the development plan.

For small HMO conversions in an area with a C3 to C4 direction, expect the authority to look at concentration of similar uses in the locality, amenity for neighbours, bin and cycle storage, and parking. Many authorities apply a threshold policy based on the proportion of HMOs within a stated radius, and they will have the data.

Parking is where applications are often won or lost, and a properly conducted Parking Survey carried out to a recognised methodology carries far more weight than an assertion that the street has capacity. The case for the scheme belongs in a Planning Statement that addresses the concentration policy directly rather than avoiding it. Designation checks around the property are a separate exercise, covered in the note on using MAGIC to check designations around a site.

This is general guidance, not legal advice. A lawful development certificate is the only formal way to confirm that works or a use are lawful, so check the position with your local planning authority or a qualified professional before relying on it.
