Article 4 directions that restrict changes of use
An article 4 direction moves a permitted change of use back into the application process. How to check whether one covers a property, what the notice period means, and what the application needs.
An article 4 direction for a change of use does one thing: it withdraws a permitted development right in a defined area, so that a change which would otherwise happen automatically now needs a planning application. It does not make the change unlawful, and it does not tell you the application will be refused. It moves the decision from the Order to the council.
For anyone buying to convert, this is the search that gets missed. A house bought for a small house in multiple occupation in a university city, or an office bought for flats in a town centre, can be covered by a direction that was confirmed years earlier and sits on a map most conveyancers never open.
The power comes from article 4 of the Town and Country Planning (General Permitted Development) (England) Order 2015, and the procedure sits in Schedule 3 to the same Order.
Directions that remove the C3 to C4 change
Class L of Part 3 allows movement between use Class C3, a dwellinghouse, and Class C4, a small house in multiple occupation for between three and six unrelated people sharing facilities. The change runs in both directions without an application.
Councils in university towns and in areas with concentrated private renting routinely withdraw the C3 to C4 direction of travel, leaving the reverse change permitted. The direction usually covers named wards rather than the whole district, and it is often paired with a supplementary planning document setting a concentration threshold, expressed as a percentage of properties within a radius of the application site.
Two things follow for an investor. First, a house already in lawful C4 use before the direction took effect keeps that use, which is why the planning history and the evidence of use matter so much. Second, anything above six occupiers is a large house in multiple occupation and falls outside Class C4 altogether into sui generis, where no permitted change has ever existed. Growing an existing house in multiple occupation is not a neutral act, and the question of when doing more of the same needs consent is decided on the facts of the planning unit rather than on the licence position.
Directions aimed at commercial to residential change
Class MA of Part 3 permits change from Class E commercial, business and service use to Class C3 dwellinghouses, subject to prior approval on a defined list of matters. Councils have used article 4 to switch that off across primary shopping frontages, town centres and designated employment areas.
National policy in the current Framework, published on 17 August 2026, holds directions of this kind to a tighter test than others. A direction withdrawing a change from non-residential to residential use is expected to be limited to cases where it is necessary to avoid wholly unacceptable adverse impacts, based on clear evidence and covering the smallest area that works. Councils that drew a line around an entire town centre have had directions modified for that reason.
Retail units with flats above are a particular trap, because the upper floors may sit in a different planning unit from the shop. Our note on retail to residential above a shop works through the sequence, and the underlying question of how the planning unit is identified decides which rights attach to which part of the building.
Checking whether a property is covered
| Where to look | What it tells you |
|---|---|
| Planning data service, article 4 direction datasets | The direction, its area boundary and the date it took effect |
| The council's policies map or local plan interactive map | The definitive local boundary, ward by ward |
| The council's planning policy pages | The direction notice, the confirming report and any accompanying guidance |
| Local land charges search | Whether the property is recorded as affected |
Do not rely on a single source. The national dataset is only as current as the council's last submission, and a direction confirmed three months ago may not be there yet. Ring the planning policy team and ask for the confirmed direction and its plan in writing, then keep the email.
Read the direction itself rather than a paraphrase of it. Directions name the classes they withdraw, and a direction that removes Part 1 householder rights in a conservation area has nothing to do with use class changes.
Notice, confirmation and compensation
Most directions are made in draft, advertised locally, notified to owners and occupiers where practicable, and open to representations for a stated period of at least 21 days before the council decides whether to confirm. Immediate directions are available in limited circumstances and take effect straight away, but still require confirmation within a fixed period or they lapse.
Compensation is the part landlords misunderstand. Section 108 of the Town and Country Planning Act 1990 allows a claim for abortive expenditure and other loss where a right is withdrawn and permission is later refused. The liability disappears if the council gives at least 12 months' notice before the direction takes effect, which is why almost every modern direction is made with a year's delay built in.
That notice period is a window. If the direction is confirmed in March to take effect the following March, a change of use begun and completed before the effective date is lawful. Begun means actually begun, and for a change of use that means the new use has actually started, not that the builders have been booked.
Applying where a direction is in force
The application is an ordinary full application for change of use. One point is worth having in front of you at the counter: no fee is payable where planning permission is required only because a direction has withdrawn a permitted development right. Councils sometimes invoice anyway, and the fee regulations are the answer.
What the application needs depends on the reason the direction exists. For a house in multiple occupation, expect to address the concentration policy, room sizes against the nationally described space standard where the council applies it, refuse and cycle storage, sound insulation between rooms, and on-street parking pressure. A Parking Survey carried out to the established overnight and weekend methodology is the usual way to answer the highway objection with evidence rather than assertion.
For a commercial to residential change, the case turns on the vitality of the frontage, the loss of employment floorspace, residential amenity in a mixed setting, and daylight to the proposed flats. A Planning Statement that sets out the marketing history of the unit, the policy conflict and the reasons the direction's underlying concern is not engaged on this site does more work than any other document in the pack.
Commenting on a direction before it is confirmed
The consultation stage is the least costly point at which to influence the outcome. Representations that work are specific: they identify a street or a block where the evidence does not support the concern, they point to the vacancy record, or they argue for a smaller boundary rather than opposing the direction outright.
After confirmation, the routes are narrow. The Secretary of State can modify or cancel a direction, and judicial review is available on ordinary public law grounds within the usual time limit. Neither is a quick answer to a purchase that has already completed.
So run the check before exchange, not after. Ask the council for the confirmed direction, the plan and the date it took effect, and price a planning application into the deal if the answer comes back positive. PlanScope can draft the supporting statement for that application in minutes, with the site facts it does not hold flagged for you to fill in. PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval.
This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.
Frequently asked questions
How do I check whether an article 4 direction applies to a property?
Use the planning data service article 4 datasets, the council's policies map and the council's planning policy pages together, then ask the planning policy team for the confirmed direction and its plan in writing. The national dataset lags behind recent confirmations, so a direction made in the last few months may not appear there yet.
Does an article 4 direction make a change of use unlawful?
No. It withdraws the permitted development right so that the change needs planning permission instead of happening automatically. The council then decides the application on its merits against the development plan. A use that was already lawfully established before the direction took effect is unaffected by it.
Is there a fee for an application needed only because of a direction?
No fee is payable where planning permission is required solely because an article 4 direction has withdrawn a permitted development right. The same applies where a condition on an earlier permission removed the right. Councils occasionally raise an invoice in error, so quote the fee regulations when you submit.
Why do directions usually take effect a year after confirmation?
Section 108 of the Town and Country Planning Act 1990 allows compensation claims for loss caused by withdrawing a permitted development right. That liability does not arise if the council gives at least twelve months notice before the direction takes effect, so councils build the delay in. The gap is a window in which the change can still be made.
Can I still convert a house to a small HMO in a direction area?
You can apply. The council will assess the application against its concentration policy, amenity standards, refuse and cycle storage and on-street parking pressure. A parking survey carried out to the recognised overnight and weekend methodology is the usual evidence on highways. Six occupiers is the ceiling for Class C4; above that the use is sui generis.
