RM6 primarily covers Chadwell Heath in Barking and Dagenham. It also touches Redbridge.
Decisions for RM6 are made by Barking and Dagenham 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 Barking and Dagenham: No.
Building regs from £950. We do not charge hourly. Free site survey across all RM6 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. Barking and Dagenham Council timelines align with the national norm.

Every RM6 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. RM6 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| RM6 | Chadwell Heath | 1930s semi-detached | A drawing package in Chadwell Heath may land with Barking and Dagenham Council or Redbridge Council — RM6 crosses the boundary, and the RM6 policies map decides it street by street. |
| RM6 | Marks Gate | Post-war estate | Marks Gate sits inside RM6; drawing package proposals here are determined by Barking and Dagenham Council. |
| RM8 | Becontree / Dagenham | 1920s-30s estate housing (Becontree) | Adjoining district to RM6, also inside Barking and Dagenham for drawing package purposes. |

Roof pitch, wall build-up and plot depth change every few RM6 streets, and each one changes what a drawing package can achieve at that address.
