E10 primarily covers Leyton in Waltham Forest.
Decisions for E10 are made by Waltham Forest Council. Standard Permitted Development rules apply for most rear extensions and loft conversions on terraced and semi-detached houses, unless the property is in a conservation area, is listed, or sits under an Article 4 Direction. Article 4 in Waltham Forest: Yes.
Building regs from £950. We do not charge hourly. Free site survey across all E10 addresses.
From first call to planning decision: typically 12–14 weeks. Site survey week 1, design weeks 2–3, validation 1–2 weeks, statutory 8-week determination. Waltham Forest Council timelines align with the national norm.
Leyton in E10 is characterised by the housing stock of Waltham Forest — broadly victorian terraces across walthamstow, leyton and leytonstone.

Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every E10 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. E10 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| E10 | Leyton | Victorian terraces | E10 covers Leyton only; Waltham Forest Council handles the drawing package. |
| E4 | Chingford / Highams Park | 1930s semi-detached, Edwardian villas | Adjoining district to E10, also inside Waltham Forest for drawing package purposes. |
| E11 | Leytonstone / Wanstead / Snaresbrook | Victorian terraces, Edwardian villas | Adjoining district to E10, also inside Waltham Forest for drawing package purposes. |
| E17 | Walthamstow | Victorian terraces | Adjoining district to E10, also inside Waltham Forest for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few E10 streets, and each one changes what a drawing package can achieve at that address.
Conservation areas covering E10 (Leyton): Waltham Forest Council runs 17, and Walthamstow Village, Lloyd Park, Leyton are the ones E10 (Leyton) owners meet most. A drawing package inside a E10 (Leyton) conservation area loses permitted development, so the E10 (Leyton) submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Walthamstow Village a drawing package is judged on the street elevation first.
What Article 4 removes near E10 (Leyton): Article 4 for HMO conversions in key residential streets. Before pricing a drawing package we check whether the E10 address is inside the mapped area, because Waltham Forest Council draws the E10 (Leyton) boundary street by street rather than across the whole of E10 (Leyton).
E10 (Leyton) housing stock: 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. Read that before choosing a drawing package route in E10 (Leyton) — construction, not postcode, sets what is achievable. Waltham Forest Council charges £548 for a householder application and has 8 weeks to determine it.
