A ‘prior approval not required’ ruling means the extension may be built as notified. Ealing has uploaded no Article 4 register to the national platform, so any direction affecting an address has to be checked on the council’s own policies map.

Answers for Ealing

What can I build under PD in Ealing without planning?

Single-storey rear extension up to 3m deep (attached house) or 4m (detached); side extension up to half the original width; loft conversion up to 40m³ (terraced) or 50m³ (semi-detached); single-storey outbuilding within the curtilage; replacement windows and doors. All subject to material match, eaves setback (20cm), and not facing a highway.

Does Permitted Development apply to flats in Ealing?

No. The householder permitted development rights attach to houses, Class C3 dwellinghouses, and a flat or maisonette is excluded from them. Almost any external change to a flat in Ealing therefore starts life as a full planning application, and frequently a party wall notice as well.

Are PD rights different in a conservation area?

Yes, and the reduction is severe. Within a conservation area the side extension right disappears altogether, as does the two-storey rear extension right; cladding an elevation stops being permitted; taking down a chimney stack needs consent; and roof enlargement is restricted to the point where most dormers become a planning application. Ealing's own designation list runs to 30 areas, so the first question on any scheme is which side of a boundary line the house sits on.

What is a Lawful Development Certificate?

An LDC is a formal ruling from the council that your proposal needs no planning permission. Getting one is optional and close to essential, because a buyer's conveyancer will come looking for it years later. Ealing recorded 2,048 lawful development certificates across the twelve quarters MHCLG has published up to March 2026 — the third largest count of any London borough, behind Barnet and Redbridge, out of 36,657 recorded capital-wide. The statutory fee for a certificate of proposed use is half the householder application fee, £274 against £548, at the rates from 1 April 2026; the drawings sit on top of that. Contains public sector information licensed under the Open Government Licence v3.0

Do I need building regulations even under PD?

Yes, always. Permitted development is a planning concept and nothing more; it removes the need to ask the council for permission and removes nothing else. The work still has to satisfy building control on structure, insulation, fire escape, drainage and ventilation, signed off on a separate track. We produce the planning-route evidence and the building regs drawings from one survey.

Where in Ealing does a permitted development scheme actually get determined?

Each Ealing postcode district below, what has been built there, and which council would take the application if the permitted development route turns out to be closed. The money column is statute and not our quote: a householder application costs £548, prior approval on a larger rear extension £249, and a certificate £274.

PostcodeAreaDominant stockWhat it means for a permitted development scheme
NW10Willesden / Harlesden / Kensal GreenModern apartments, post-war estatesAn NW10 address in Willesden, Harlesden or Kensal Green can sit in Brent or in Ealing. Whichever it is decides who you would apply to once the permitted development limits are exceeded, and the two councils publish different validation lists.
W4Chiswick / Bedford ParkArts & Crafts villas (listed)Chiswick and Bedford Park share W4 between Hounslow and Ealing. Bedford Park is a conservation area as well, so a W4 scheme is worth checking twice: once for the authority, once for whether the permitted development right survives at all.
W3ActonVictorian and Edwardian terracesW3 covers Acton and crosses into Hounslow along its southern edge. Confirm the authority from the W3 policies map before drawing, because a certificate applied for at the wrong council is simply returned.
W5EalingEdwardian villas, Victorian terracesW5 covers Ealing only; Ealing Council handles the permitted development scheme.
W7HanwellEdwardian villas, 1930s semi-detachedHanwell lies wholly within W7 and wholly within Ealing's remit. The Hanwell conservation area covers part of it, and that is where the permitted development question usually turns.
W13West EalingEdwardian terracesW13 sits entirely with Ealing Council, so West Ealing schemes are judged against Ealing's Local Plan and its own householder design guidance.
UB1Southall NorthEdwardian terraces, post-war flatsSouthall North lies inside UB1 with no boundary complication, so Ealing Council handles every UB1 certificate and every UB1 application.
UB2Southall SouthEdwardian terraces, post-war flatsUB2 holds Southall South on its own. One authority, one Local Plan, and the HMO Article 4 direction to check against the specific street.

Which Ealing neighbourhoods suit a permitted development scheme best?

Two houses on neighbouring Ealing roads can get different answers, because the pitch of the roof, what the walls are made of and the length of the garden behind each bear directly on whether a scheme stays inside the permitted development limits.

Does Ealing planning policy restrict a permitted development scheme?

Ealing conservation designations: there are 30 of them, Bedford Park, Acton Green and Hanwell among them, and Ealing Broadway is the one that most often forces a redesign. Designation costs money in a specific and measurable way: it shuts off prior approval, which costs £249 and is determined in 6 weeks, and pushes the same extension onto a householder application at £548 determined in 8 weeks — usually with a heritage statement attached, and often with a different roof. Both figures are England-wide statutory fees as at 1 April 2026, identical in every borough.

What Article 4 removes near Ealing: Article 4 for HMOs in specific streets in Acton, Ealing and Southall. Before pricing a permitted development scheme we check whether the W3 address is inside the mapped area, because Ealing Council draws the Ealing boundary street by street rather than across the whole of Ealing.

The building fabric around Ealing: Victorian and Edwardian villas in Ealing central; 1930s semi-detached in Northolt and Hanwell; mansion blocks along main roads; Bedford Park is a listed Arts & Crafts garden suburb. Leafy outer-west London; Bedford Park conservation area has strict heritage controls; rest of borough generally permissive. A permitted development scheme in Ealing is scoped against that stock first.
