What can be built here without applying for permission, from single-storey rear extensions to loft conversions and side extensions, and where those rights run out. Of 736 larger householder prior approvals determined here over those same three reporting years, 280 were refused: a 38.0% refusal share, where London averages 24.9%, so the exceptions here repay knowing about early.
Yes, but check the Article 4 register first. Waltham Forest holds 807 Article 4 areas, more than any other London borough by a wide margin, against only 15 conservation areas. It still issued 1,804 lawful development certificates in three years.

Sources: registers from the MHCLG Planning Data Platform, retrieved 1 September 2026, excluding revoked entries; decision figures from MHCLG PS1 and PS2, twelve quarters to March 2026; fees from the Town and Country Planning (Fees for Applications) (England) Regulations 2012 as amended, 2026 rates. The 1,804 certificates against 807 Article 4 areas is the honest picture: rights survive on most streets and are gone on a great many.
In detailSingle-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.
No. Permitted development belongs to houses alone, meaning Class C3 dwellinghouses under Schedule 2, Part 1 of the Town and Country Planning (General Permitted Development) (England) Order 2015. A flat or maisonette needs a full planning application for very nearly every external alteration, including ones a neighbouring house could carry out freely.
Yes, and sharply. Inside a conservation area you lose side extensions and two-storey rear extensions from permitted development, cladding goes, removing a chimney needs consent, and enlarging a roof is out altogether. This council runs 17 designated areas, so establishing whether the address falls inside one is the first job of any feasibility check.
An LDC is a written finding by the council that what you built needed no planning permission. Holding one is voluntary, right up to the day a buyer's solicitor asks for it. Waltham Forest logged 1,804 lawful development certificates over the three MHCLG reporting years that close at March 2026. The fee for a lawful development certificate is £274, on top of the drawings.
Yes, and they are an entirely separate system. Permitted development removes the need for planning permission and removes nothing whatever from the building control duty over structure, insulation, fire safety, drainage and ventilation. We produce the planning drawings and the building regs drawings together, so the two sets agree with one another.

Each postcode district the borough reaches into, its prevailing housing, and whichever council will determine an application sent from there. Two of the districts cross a borough boundary. The fees listed are 2026 statutory amounts due to the council, not what this practice charges.
| Postcode | Area | Dominant stock | What it means for a permitted development scheme |
|---|---|---|---|
| E4 | Chingford / Highams Park | 1930s semi-detached, Edwardian villas | E4 covers Chingford and Highams Park and sits wholly inside the borough, so a single council determines everything submitted from it, with no boundary check and no second policies map to consult. |
| E10 | Leyton | Victorian terraces | A permitted development scheme at an E10 address in Leyton is determined by Waltham Forest Council under its own Local Plan policies for Leyton. |
| E11 | Leytonstone / Wanstead / Snaresbrook | Victorian terraces, Edwardian villas | E11 straddles the line between Waltham Forest and Redbridge across Leytonstone, Wanstead and Snaresbrook, so an address there is tested against both councils' policies maps before anything is submitted to either of them. |
| E17 | Walthamstow | Victorian terraces | E17 is Walthamstow and lies entirely within the borough. Walthamstow Village sits inside the district, so an address here needs its conservation boundary checked before permitted development is assumed for anything visible from the street. |
Plot depth, roof pitch and flood zone all change street by street here. Flood Zone 2 covers 12.47% of the borough's 38.81 square kilometres and Zone 3 a further 5.72%. Permitted development is untouched by that, but the moment a scheme falls outside it and becomes a planning application, anything in Zone 2 or Zone 3 has to carry a Flood Risk Assessment into the council with it.
Conservation areas in this borough: the council runs 17, of which Walthamstow Village, Lloyd Park and Leyton are the three owners run into most. Nothing inside those boundaries is permitted development, which pushes the work onto a householder application with an 8-week clock in place of a prior approval running to 6. The householder application fee in England is £548. The fee for a larger householder prior approval is £249. In Lloyd Park the street elevation is what a scheme gets judged on first.
Article 4 and your Waltham Forest permitted development scheme: Article 4 for HMO conversions in key residential streets. At a E4 address that matters twice over, because Waltham Forest Council applies the direction unevenly across Waltham Forest — we read the Waltham Forest policies map for the exact E4 address before quoting permitted development schemes.
The building fabric around Waltham Forest: Victorian terraces across Walthamstow, Leyton and Leytonstone; 1930s semi-detached in Chingford and Highams Park; post-war flats around Walthamstow Central. Walthamstow Village is a designated conservation area with tight design controls; rest of borough is generally permissive with active side-return extension approvals. A permitted development scheme in Waltham Forest is scoped against that stock first.
