IG7 primarily covers Chigwell in Redbridge.
Decisions for IG7 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 IG7 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.
Chigwell in IG7 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 IG7 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. IG7 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| IG7 | Chigwell | mixed Victorian and inter-war stock | IG7 is split between two counties. Chigwell and Chigwell Row are in Essex, where Epping Forest District Council is the planning authority; the Hainault end of the district is in the London Borough of Redbridge. The postcode itself decides none of this, and the difference is real — an Essex application is judged against the Epping Forest local plan, with Essex County Council handling highways. |
| E18 | South Woodford | Edwardian villas, 1930s semi-detached | Adjoining district to IG7, also inside Redbridge for drawing package purposes. |
| IG1 | Ilford Central | Edwardian terraces, post-war flats | Adjoining district to IG7, also inside Redbridge for drawing package purposes. |
| IG2 | Gants Hill / Newbury Park | 1930s semi-detached | Adjoining district to IG7, also inside Redbridge for drawing package purposes. |
| IG3 | Seven Kings | mixed stock | Adjoining district to IG7, also inside Redbridge for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few IG7 streets, and each one changes what a drawing package can achieve at that address.
IG7 (Chigwell) conservation designations: there are 14 across Redbridge Council, Wanstead Village, Snaresbrook, Aldersbrook among them. Designation costs a IG7 (Chigwell) owner the permitted-development route: a drawing package then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Woodford Green is the IG7 (Chigwell) designation that most often changes a drawing package design.
Article 4 and your IG7 (Chigwell) drawing package: Redbridge Council has made no borough-wide direction, so permitted development for a drawing package in IG7 (Chigwell) generally survives outside IG7 (Chigwell) conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a IG7 owner records that a drawing package was lawful.
IG7 (Chigwell) 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 IG7 (Chigwell) — construction, not postcode, sets what is achievable. Redbridge Council charges £548 for a householder application and has 8 weeks to determine it.
