East London splits cleanly in two. Inner east — Hackney and Tower Hamlets — is dense, conversion-heavy and tightly designated. Outer east — Redbridge, Havering, Barking and Dagenham — is interwar suburbia where permitted development still does most of the work.
Seven boroughs, and the contrast across them is the widest in London. A Hackney project is usually a flat conversion or a mansard in a conservation area with an Article 4 direction attached. A Havering project twelve miles east is usually a hip-to-gable loft on a 1930s semi that needs nothing more than a £274 certificate.
Hackney and Tower Hamlets are among the most heavily designated authorities in the country. Between them they hold dozens of conservation areas covering the Georgian terraces of Spitalfields and the early Victorian streets of De Beauvoir, London Fields and Clapton, and both operate Article 4 directions that remove permitted development rights for roof alterations and front-elevation changes across defined areas.
A second inner-east factor is tenure. Much of the housing stock is flats and maisonettes rather than houses, either purpose-built or converted. Flats have no permitted development rights whatsoever, so every alteration is a full application at £548, and a leasehold or shared-freehold property also needs the correct ownership certificate and notice served on the freeholder — a routine cause of invalidation.
Waltham Forest sits on the boundary, with Article 4 controls across parts of Walthamstow and Leyton. Beyond it, Redbridge, Havering and Barking and Dagenham are dominated by interwar and early post-war semi-detached and terraced housing on generous plots, where the 40 and 50 cubic metre loft allowances and the 3 metre rear extension depth are genuinely available and the prior approval route to 6 metres is worth using.

We cover seven: Hackney, Tower Hamlets, Newham, Waltham Forest, Redbridge, Havering and Barking and Dagenham. Each is a separate planning authority, and the difference between inner and outer east is the single biggest variable in how your project is handled.
You will need a full planning application at £548, because flats and maisonettes have no permitted development rights. You will also need freeholder consent in parallel, and the correct ownership certificate on the application — Certificate B with notice served, not Certificate A.
Generally yes. Redbridge, Havering and Barking and Dagenham are dominated by interwar semi-detached and terraced houses outside designated areas, where the 40 and 50 cubic metre loft allowances and the 3 metre rear extension depth apply, and the prior approval route extends that to 6 metres.
A habitat mitigation payment sought on development that adds bedrooms within the zone of influence around Epping Forest, which reaches into Waltham Forest and Redbridge. It is separate from the application fee and is calculated by the council on a per-dwelling basis.
Eight weeks from validation for a householder application, plus one to three weeks for registration. Hackney and Tower Hamlets carry high caseloads, so allow the longer end of that range when planning a build programme.
