RM10 primarily covers Dagenham in Barking and Dagenham.
Decisions for RM10 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 RM10 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.
Dagenham in RM10 is characterised by the housing stock of Barking and Dagenham — broadly becontree estate (the world's largest council estate when built, 1920s-30s) dominates.

Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every RM10 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. RM10 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| RM10 | Dagenham | 1920s-30s estate housing (Becontree) | RM10 covers Dagenham only; Barking and Dagenham Council handles the drawing package. |
| RM6 | Chadwell Heath | 1930s semi-detached | Adjoining district to RM10, also inside Barking and Dagenham for drawing package purposes. |
| RM8 | Becontree / Dagenham | 1920s-30s estate housing (Becontree) | Adjoining district to RM10, also inside Barking and Dagenham for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few RM10 streets, and each one changes what a drawing package can achieve at that address.
RM10 (Dagenham) conservation designations: there are 9 across Barking and Dagenham Council, Becontree Estate (historic), Eastbury, Valence House among them. Designation costs a RM10 (Dagenham) 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. Becontree Estate (historic) is the RM10 (Dagenham) designation that most often changes a drawing package design.
Article 4 and your RM10 (Dagenham) drawing package: Barking and Dagenham Council has made no borough-wide direction, so permitted development for a drawing package in RM10 (Dagenham) generally survives outside RM10 (Dagenham) conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a RM10 owner records that a drawing package was lawful.
RM10 (Dagenham) housing stock: Becontree Estate (the world's largest council estate when built, 1920s-30s) dominates; post-war estates around Barking town; new-build riverside. Major regeneration in Barking Riverside; mostly permissive planning outside conservation pockets. Read that before choosing a drawing package route in RM10 (Dagenham) — construction, not postcode, sets what is achievable. Barking and Dagenham Council charges £548 for a householder application and has 8 weeks to determine it.
