What Is an Article 4 Direction?

An Article 4 Direction is a legal instrument that removes some or all permitted development (PD) rights granted by the Town and Country Planning (General Permitted Development) (England) Order 2015 (GPDO 2015). Without an A4D, the GPDO grants automatic planning permission for a wide range of minor works — extensions, loft conversions, outbuildings, and more — meaning a formal application is not needed.

Where an A4D is in force, those rights are suspended. Any work that falls within the removed class requires a full planning application to the local planning authority (LPA), just as if the GPDO right had never existed.

A4Ds can be area-wide (covering an entire conservation area, ward, or borough) or site-specific (targeting a single address or building).

Legal Basis and Who Makes Them

Article 4 of the GPDO 2015 confers the power to make directions. They can be made by:

• The LPA — by far the most common route; used for conservation areas, HMO management, and suburban character protection.
• The Secretary of State — rare, but possible where a matter of national concern arises.

LPAs must follow the procedural requirements in Schedule 3 of the GPDO 2015 when making a direction, including giving notice and consulting affected parties.

Why LPAs Use Article 4 Directions

LPAs make A4Ds when they consider that the automatic grant of PD rights would be inappropriate given the character or circumstances of an area. Common reasons include:

• Conservation area protection: Preventing unsympathetic extensions, dormer windows, or material changes that would erode the uniform character of a historic streetscape.
• HMO management: Removing the Class L right (C3 dwelling to C4 HMO) to require planning permission for conversions to houses in multiple occupation, allowing the LPA to manage concentrations of HMOs.
• Agricultural land: Preventing the conversion of agricultural buildings to residential or commercial uses without scrutiny.
• Character areas: Protecting the appearance of suburban streets from front extensions or garage conversions that could affect parking and streetscene.

The Confirmation Process

Most A4Ds are made as immediate directions, taking effect on the date they are made. This prevents a rush of PD works before the direction comes into force. However, an immediate direction must be confirmed within 6 months or it lapses and PD rights are restored.

Before confirming, the LPA must:

1. Notify owners and occupiers of affected land (or publish notice for area-wide directions).
2. Allow a minimum 21-day consultation period for representations.
3. Consider any representations received before deciding whether to confirm.

Once confirmed, an A4D remains in force indefinitely unless the LPA cancels it by a subsequent direction.

Is Compensation Payable?

Compensation for the loss of PD rights through an A4D is possible under section 108 of the Town and Country Planning Act 1990, but only in limited circumstances:

• The work must have been started or completed within 12 months before the A4D was made.
• The work must have been carried out in reliance on the PD right that has since been removed.
• A subsequent planning application for the same development must have been refused or granted subject to conditions more restrictive than under the PD right.

In practice, compensation claims are rare and difficult to succeed on. The courts have interpreted the test strictly. Most A4Ds are made before any development commences, so the 12-month rule rarely applies.

How to Find Out If One Applies to You

See our companion guide: How to Check If an Article 4 Direction Applies to Your Property. In brief:

• Check your LPA’s website — most publish A4D maps and schedules.
• Search the Local Land Charges Register via GOV.UK.
• Use the Planning Portal property search.
• Submit a pre-application enquiry to the LPA.
