Article 4 directions: finding the ones covering your street

An Article 4 direction removes permitted development rights in a defined area, and the only document that tells you reliably what it covers is the direction itself. Council web pages summarise, national datasets generalise and estate agents guess. To find the directions affecting a specific street you need three sources checked against each other: the national open dataset as a first pass, the council's own published directions, and a local land charges search on the property.

Where councils publish their directions

Article 4 of the General Permitted Development Order 2015 lets a local planning authority withdraw specified permitted development rights, and Schedule 3 to the Order sets out how a direction is made, publicised and confirmed. The authority has to give notice locally and make the direction available for inspection.

In practice most councils keep their directions on a planning policy page, sometimes under conservation, sometimes under housing where the direction concerns houses in multiple occupation. A few keep them on a local land charges page and nowhere else. Search the council's site for the phrase rather than browsing the menus, and look for a schedule or register listing every direction with its date.

What you want from that page is the direction document, usually a PDF with a map or a schedule of addresses attached. A summary table with the words "parts of the town centre" in it is not a substitute.

Using the national open dataset as a first pass

The planning data service at planning.data.gov.uk publishes datasets for article 4 directions and their areas, assembled from what authorities have provided. It is the quickest way to see whether a property is likely to be affected, and it is useful for checking across a boundary where a site sits near two authorities.

Treat it as a first pass. Coverage varies by authority, geometries are sometimes approximate, and the dataset records what a council has published rather than the legal instrument. A negative result there is not evidence that no direction exists.

The same caution applies to any interactive constraints map on a council's own site. Those layers are maintained by different teams from the ones who make the directions, and they lag.

One more source helps on any purchase, which is the planning history of the property and its neighbours. A run of refusals citing an Article 4 direction on the same street tells you the direction is real and being applied, which a map layer does not.

Reading the direction rather than the web page

Open the direction and find five things.

1. Which classes are withdrawn. A direction may remove a single class, such as Part 3 Class MA for commercial to residential change, or a list, such as Part 1 Classes A to H for householder development. The difference decides whether the extension you had in mind is caught.
2. Whether any part of a class is withdrawn rather than the whole. Directions frequently remove rights only in respect of elevations fronting a highway, or only for particular alterations, and the qualifying words matter.
3. The area, defined by a map, a schedule of streets or a schedule of individual addresses. Boundaries follow property lines, and a direction can stop halfway along a terrace.
4. The date it takes effect. A direction made with immediate effect must be confirmed within a defined period or it lapses, while a direction made on notice takes effect later. Compensation provisions under section 108 of the Town and Country Planning Act 1990 are the reason authorities usually give at least twelve months' notice.
5. Whether it was confirmed. An unconfirmed immediate direction that lapsed is not in force, and the council's page may not have been updated.

Where the direction removes householder rights, the practical consequences are the ones covered in our notes on rear extension depth and the 45-degree test, on outbuildings used for business or letting and on dropped kerbs and front gardens, because those are the works most often caught.

Local land charges searches and what they show

An Article 4 direction is registrable as a local land charge, so an official search against the property should reveal it. That is why the conveyancing search picks up directions the buyer never heard of.

Two distinctions are worth knowing. An official search is carried out by the registering authority and carries a compensation remedy if it is wrong. A personal search is carried out by an agent inspecting the register and does not. For a purchase where permitted development value is part of the price, the official search is the one to rely on.

Searches also have a shelf life. A direction made after the search was carried out will not appear on it, and directions are sometimes made quickly where a council is responding to a pattern of conversions.

Directions in progress and the dates that matter

A direction that has been resolved upon but has not yet taken effect is invisible to most searches and fatal to a plan that depends on permitted development.

Check the planning committee or cabinet agendas for the last twelve months, the council's consultation page, and any local plan or supplementary document that signals an intention to make directions. Councils considering a direction on houses in multiple occupation usually consult on it publicly, and the consultation is easy to find if you look for it.

Where a direction is coming, the date it takes effect is the only thing that matters commercially. Works begun under permitted development before that date are lawful. Works begun afterwards are not, and starting early to beat the deadline is a decision to take with advice rather than optimism.

Confirming the position in writing

For anything with money attached, get it in writing. Three routes, in increasing order of certainty.

Ask the council's duty planner by email, naming the address and the works, and keep the reply. It is quick and it is not binding.

Ask for the direction document itself and read it, which removes the risk of a summary being wrong.

Apply for a certificate of lawfulness for a proposed use or development under section 192 of the 1990 Act. The council decides whether what you propose is lawful, and a certificate is conclusive for the works described. It costs half the planning application fee and takes eight weeks, and it is the only answer a lender or a buyer's solicitor will accept without argument.

What to do when sources disagree

The direction is the legal instrument. The dataset, the constraints map and the council's summary page are descriptions of it, and where they conflict the direction wins.

If the direction itself is ambiguous, for example where the map and the schedule of addresses do not match, put the ambiguity to the council in writing and ask them to confirm which governs. Keep the correspondence, because an officer's written confirmation is worth having even though it does not bind the authority. Where the money involved justifies it, a certificate of lawfulness resolves it definitively, and the supporting documents for that application are short.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it. A lawful development certificate is the only formal way to confirm that works are lawful. PlanScope provides AI-assisted draft reports for planning applications.
