Every RM8 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. RM8 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| RM8 | Becontree / Dagenham | 1920s-30s estate housing (Becontree) | Becontree / Dagenham sits wholly inside RM8, so Barking and Dagenham Council validates every drawing package submitted from an RM8 address. |
| RM8 | Dagenham | 1920s-30s estate housing (Becontree) | Dagenham sits inside RM8; drawing package proposals here are determined by Barking and Dagenham Council. |
| RM8 | Becontree | 1920s-30s estate housing | Becontree sits inside RM8; drawing package proposals here are determined by Barking and Dagenham Council. |
| RM6 | Chadwell Heath | 1930s semi-detached | Adjoining district to RM8, also inside Barking and Dagenham for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few RM8 streets, and each one changes what a drawing package can achieve at that address.
RM8 (Becontree / Dagenham) conservation designations: there are 9 across Barking and Dagenham Council, Becontree Estate (historic), Eastbury, Valence House among them.
