Article 4 Direction Advice in London

Article 3 of the Town and Country Planning (General Permitted Development) (England) Order 2015 grants planning permission for the classes of development described in Schedule 2. That permission is subject to the rest of the Order and to every applicable exception, limitation and condition. A project is therefore not permitted development merely because it resembles a familiar extension, roof alteration, change of use or other class. The property, use and complete operation must satisfy the current wording that applies to it.

Article 4 provides a mechanism by which the Secretary of State or a local planning authority can disapply the article 3 permission for specified Schedule 2 development on specified land or a specified site, subject to the Order’s exclusions. The direction acts on that defined permission; it does not rewrite every planning rule for a borough. This is why the investigation begins with the potential permitted-development class rather than with a map pin or a general statement that an area “has Article 4”.

The complete address is a starting reference, not the whole legal answer. Record the application-site boundary, the planning unit, current lawful use, property type and any land or building parts affected by the proposal. A postal address may contain more than one planning unit, while one planning unit may extend beyond the building named in correspondence. Flats, dwellinghouses, mixed-use premises, commercial units and land can engage different Schedule 2 provisions, so an assumption based on the street or outward appearance is unsafe.

The register should identify the responsible local planning authority and retain the records used to reach that conclusion. Borough, postcode, neighbourhood and conservation-area names do not substitute for the site boundary. A nearby house can sit inside a direction when the subject property does not, or can be affected by a different development class. A direction applying to one use or operation cannot be transferred to another merely because both sites appear on the same council webpage.

“Loft”, “windows”, “basement”, “HMO” or “change of use” is not a sufficient description for an Article 4 conclusion. Define what will physically or operationally change, where it occurs, how the elements relate and whether the proposal contains more than one operation. Drawings, dimensions, use information and photographs may be needed to distinguish the actual development from a shorthand project name.

The next step is to identify the exact Schedule 2 Part, Class and paragraph that could grant permission. Test the defined proposal against all relevant limitations and conditions and any prior-approval procedure. If it fails that baseline, it cannot become permitted merely because no Article 4 direction applies. Conversely, a direction withdrawing one named class does not silently withdraw another. Planning conditions or an earlier permission can also restrict a route and must be checked independently.

A council register is a route to evidence, not the evidence in isolation. Open and retain the actual direction, its plan or property schedule, relevant notice and any confirmation, modification or cancellation material. Record the development class or paragraph identified, the land described, the plan key, exclusions and operative wording. A search result, map layer or page heading cannot establish coverage when the underlying instrument describes something narrower or different.

Match the complete site to the plan or schedule and the proposed operation to the specified development. Do not infer that every elevation, property, building type or operation within a displayed boundary is controlled. Equally, do not treat a blank or failed map as proof that no direction applies. Where the plan is unclear, the property schedule conflicts with another record or the instrument is inaccessible, mark the result unresolved and seek authoritative clarification rather than issuing a confident negative.

Status is part of scope. Under Schedule 3, a non-immediate direction becomes operative only when it has been confirmed and on its specified effective date. An immediate direction can take effect through the notice procedure but expires after six months unless confirmed. Record made, notice, confirmation and effective dates separately, together with any modification or cancellation, instead of converting a council page’s “adoption date” into a legal conclusion.

The status check should be performed for the date relevant to the advice and proposal. A proposed, made but not yet operative, expired, modified or cancelled direction is not described as though its original text currently withdraws the right. If a future effective date may affect a project programme, state the dated evidence and dependency without promising that work can lawfully be secured merely by starting quickly.

Conservation-area designation does not itself withdraw every permitted-development right. The GPDO contains its own provisions for land and development types, and a separate Article 4 direction can withdraw only the rights it specifies. A direction may concern heritage-related alterations, basement development, changes of use or another defined subject. Conservation status, postcode, neighbourhood character or apparent age therefore cannot establish Article 4 coverage.

Check statutory listing, local heritage records, planning history and conditions as separate entries. A planning condition on an earlier permission may affect reliance on permitted development even where no direction applies. Listed-building consent follows its own statutory test. A conservation appraisal can inform the design and planning merits of an application but is not the direction itself. The register should not merge those sources into a single “heritage restriction” result.

Camden, the Royal Borough of Kensington and Chelsea and Westminster publish Article 4 information and records. They are representative London lookup routes, not a complete London register and not interchangeable sources. Each authority can organise heritage, basement, use and other directions differently. For a property in another authority, use that authority’s current official record and obtain the operative instrument rather than borrowing a conclusion from these examples.

Within each register, identify the direction relevant to the land and development, then open and save its plan or property schedule and notices. Do not report “Camden Article 4”, “RBKC Article 4” or “Westminster Article 4” as though each were one borough-wide control. A borough can hold several instruments with different purposes, boundaries, classes, dates and status. The address-led audit records the one actually tested and why.

Where an operative direction withdraws the relevant permission, the specified development needs planning permission on an application. The direction does not ban the proposal and does not mean that permission will be granted or refused. The local planning authority assesses the application against the development plan and other material considerations using the proposal and evidence before it. The route conclusion and merits case should appear as separate parts of the project record.

The application scope may require drawings, a site description and proportionate supporting material suited to the development and authority’s current validation requirements. Conservation, design, amenity, use, transport, heritage or technical evidence may be relevant depending on the actual proposal; none is assumed from the words “Article 4” alone. A neighbouring decision can provide context but does not settle different land, facts, policy, design or evidence.

Section 191 of the Town and Country Planning Act 1990 provides the certificate route for a defined existing use, operation or other matter. The application must identify the land and matter whose lawfulness is asserted and provide evidence capable of supporting that conclusion. Planning merits are not the test. An existing certificate is not an abstract declaration that a property has “remaining rights”, and it does not decide work or uses outside the matter described.

For past work near an Article 4 change, assemble the operative direction material, relevant dates, plans, photographs, invoices, contracts, correspondence and other reliable evidence. Record what each item proves and where a gap remains. Do not conclude that work is lawful merely because it appears older than an online register date, because a neighbour says it was started, or because enforcement action has not been observed.

Section 192 provides the certificate route for a proposed use or operation. The proposal must be described with enough precision for its lawfulness to be assessed on the facts and law applying to it. Planning merits are irrelevant to that statutory question. The certificate does not authorise a different, larger or materially changed scheme and should not be marketed as a general confirmation that unspecified permitted-development rights survive.

The supporting record should connect the drawings and description to the exact Schedule 2 class, every relevant limitation and condition, any prior-approval question, planning history and conditions, and the Article 4 result. If the conclusion depends on dimensions, use or a site boundary, those facts must remain consistent. An unresolved assumption is identified before submission rather than hidden beneath a broad project label.

The relevant planning issue is development carried out without the required planning permission, as described by section 171A, rather than “breaching an Article 4 direction”. The direction identifies a permission that cannot be relied on for its specified scope. Whether a planning breach has occurred depends on the development, land, timing, permission and evidence. Avoid describing all unauthorised work as automatically criminal or assuming the direction itself creates that result.

Planning enforcement is discretionary. Government guidance frames action around expediency and proportionality. A council may investigate the facts and decide what response, if any, is appropriate; the existence of a direction does not make enforcement, removal or a particular outcome certain. Generic content should not speculate about limitation periods, immunity, retrospective outcomes, compensation or appeals.

National policy changed on 17 August 2026, when the Ministry of Housing, Communities and Local Government published a fully revised National Planning Policy Framework. It replaces the December 2024 edition and every earlier version back to March 2012, and it applies to England only. Any note prepared before that date is quoting superseded national policy and needs re-reading against the current Framework before it is relied on.

The 2026 Framework is also structured differently from the editions it replaces: it separates plan-making policy from national decision-making policy and identifies policies by named codes rather than the paragraph numbering earlier versions used. A paragraph number carried over from a pre-2026 article or template therefore no longer points where the writer intended, and any national-policy citation for an Article 4 direction should be taken from the current Framework text rather than copied from an older source.

The London Plan 2021 remains the current adopted strategic plan. The Draft London Plan published on 16 July 2026 is emerging consultation material, with consultation open to 15 October 2026; it is not adopted. Neither London plan proves that an Article 4 direction applies. The site-specific route still comes from the GPDO, planning history and conditions, and the exact operative direction for the land and development.

An Article 4 result changes the permission route for specified development; it does not supply the design response. Once the route is understood, test the proposal against the actual building, surroundings, adopted policy and the matters relevant to that application. Drawings should describe the complete operation consistently so that the route note, application form and merits material do not refer to different work.

Where heritage character is relevant, use the applicable designation and evidence rather than assuming every direction protects public-facing fabric. Where the direction concerns a use, basement or another subject, prepare material suited to that issue. Design quality may support a planning case, but no material, roof form, window detail, boundary treatment or precedent guarantees permission. Advice should distinguish what the direction controls from what the authority will assess on the merits.

A permitted-development conclusion, planning permission or lawful-development certificate does not provide Building Regulations approval. It also does not grant listed-building consent, landlord or freeholder approval, a Party Wall agreement, licensing approval, tree consent or notice, estate consent or another statutory or private permission. Each route has its own subject, evidence, decision-maker and programme.

The project register should list the proposed operation against every potentially relevant route, the responsible adviser, information required, status and dependency. A flat may not have the householder permitted-development rights being discussed but can still need planning and landlord checks. A listed building can need listed-building consent even where a separate planning conclusion is reached. A change of use can raise licensing or other operational requirements beyond planning.

The useful output is a short, traceable decision register. It identifies the complete site and planning unit, current use and property type, proposed operations, candidate Schedule 2 provisions, limitations and conditions, planning history, any direction documents, mapped or scheduled coverage, status dates, unresolved evidence and recommended next route. Copies or stable links to the documents reviewed sit behind the conclusion.

State the evidence date and the boundary of the instruction. A route review of one proposed roof alteration does not answer a later basement or use change. Advice based on a sketch should say so; advice based on certificate-ready measured drawings should identify them. If the council record is ambiguous, the conclusion remains conditional until authoritative evidence resolves it.
