Article 4 Directions explained

The General Permitted Development Order 2015 gives homeowners default rights to carry out certain types of work without applying for planning permission — rear extensions, loft conversions, porches, window replacements, painting brickwork, and so on. Article 4 of the GPDO gives councils a tool to withdraw some of those default rights in a specific area.

In practice this means: if you’re inside an Article 4 Direction and you want to do a type of work the direction covers, you need to apply for planning permission even though a neighbour two streets over wouldn’t. The council then decides whether to approve or refuse based on normal planning policy, usually with a strong presumption in favour of preserving the character of the area.

Article 4 Directions are most commonly used in conservation areas where the council wants tighter control over cosmetic changes, but they can exist anywhere. They’re also used in some areas to restrict the conversion of houses to flats, or offices to homes, where the government’s national permitted development rights are felt to be inappropriate locally.

Each direction is different — the council defines exactly which rights are removed and over which geographic area. But the most common targets across UK councils are:

• Windows. The right to replace original windows without permission (under Part 1 Class A). In practice, this means you can’t switch timber sash windows for UPVC double glazing without a planning application, even though that’s normally permitted development.
• Front doors. Replacing an original front door with a modern one can be restricted, to preserve the streetscape character.
• External painting of brickwork. Many London Article 4 Directions prohibit painting exposed brickwork, which would otherwise be permitted.
• Front garden paving. Removing garden boundaries and adding dropped kerbs for off-street parking is a common Article 4 target, because it changes the character of whole streets at once.
• Dormer windows on loft conversions. Even where Class B would normally allow a rear dormer, an Article 4 Direction can remove that right specifically.
• Cladding, rendering, and external finishes. Changes to the visible surface of a house.
• Satellite dishes. On front elevations in particular.
• Chimney removal. In some conservation areas.
• Change of use from house to HMO (house in multiple occupation). Used in areas with high student or rental density to preserve family housing.

1. 1. Our free postcode check (fastest). Enter your postcode on our free checker. We query the live Article 4 Direction boundaries from planning.data.gov.uk and tell you immediately which direction (if any) covers your address, along with a summary of what it restricts.
2. 2. planning.data.gov.uk directly. The government’s planning data portal publishes most Article 4 Directions as map layers. Search for “Article 4 direction area” and navigate to your borough.
3. 3. Your council’s planning portal. Every council maintains a page listing Article 4 Directions in their area, usually with downloadable PDFs of the boundary maps and the exact rights removed. Search “[council name] Article 4 Direction”.

Being inside an Article 4 Direction isn’t the end of the world. It just means you need to apply for planning permission for the specific types of work the direction covers. The practical steps:

1. 1. Read the exact direction. It will list the specific permitted development rights withdrawn. Don’t assume it covers everything — Article 4 Directions are often narrow.
2. 2. Check whether your project is affected. If your project is for a type of work the direction covers, you need to apply. If not (e.g. you’re building a rear extension but the direction only removes window rights), you can proceed as permitted development.
3. 3. Apply for planning permission. Householder application fee is currently £548. Eight-week target decision. Your application will be assessed against the council’s design guidance for the area.
4. 4. Consider pre-application advice. In areas with Article 4 Directions, councils usually offer paid pre-app advice. It’s often worth taking — the direction exists because the council cares about these details.
