IG5 primarily covers Clayhall in Redbridge.
Decisions for IG5 are made by Redbridge 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 Redbridge: No.
Building regs from £950. We do not charge hourly. Free site survey across all IG5 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. Redbridge Council timelines align with the national norm.
Clayhall in IG5 is characterised by the housing stock of Redbridge — broadly 1930s semi-detached dominates outer redbridge.

Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every IG5 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. IG5 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| IG5 | Clayhall | mixed Victorian and inter-war stock | A drawing package at an IG5 address in Clayhall is determined by Redbridge Council under its own Local Plan policies for Clayhall. |
| E18 | South Woodford | Edwardian villas, 1930s semi-detached | Adjoining district to IG5, also inside Redbridge for drawing package purposes. |
| IG1 | Ilford Central | Edwardian terraces, post-war flats | Adjoining district to IG5, also inside Redbridge for drawing package purposes. |
| IG2 | Gants Hill / Newbury Park | 1930s semi-detached | Adjoining district to IG5, also inside Redbridge for drawing package purposes. |
| IG3 | Seven Kings | mixed stock | Adjoining district to IG5, also inside Redbridge for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few IG5 streets, and each one changes what a drawing package can achieve at that address.
Conservation areas covering IG5 (Clayhall): Redbridge Council runs 14, and Wanstead Village, Snaresbrook, Aldersbrook are the ones IG5 (Clayhall) owners meet most. A drawing package inside a IG5 (Clayhall) conservation area loses permitted development, so the IG5 (Clayhall) submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Woodford Green a drawing package is judged on the street elevation first.
Article 4 and your IG5 (Clayhall) drawing package: Redbridge Council has made no borough-wide direction, so permitted development for a drawing package in IG5 (Clayhall) generally survives outside IG5 (Clayhall) conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a IG5 owner records that a drawing package was lawful.
IG5 (Clayhall) housing stock: 1930s semi-detached dominates outer Redbridge; Edwardian terraces and villas in Wanstead and South Woodford; post-war estates in Ilford central. Outer London suburban; permitted development used heavily for loft conversions and single-storey rear extensions. Read that before choosing a drawing package route in IG5 (Clayhall) — construction, not postcode, sets what is achievable. Redbridge Council charges £548 for a householder application and has 8 weeks to determine it.
