Every Barking and Dagenham postcode district we draw in, the stock that dominates it and the authority that validates a structural calculation package there. Barking and Dagenham fees below are the statutory England rates for 2026, not structural calculation package estimates.
| Postcode | Area | Dominant stock | What it means for a structural calculation package |
|---|---|---|---|
| RM6 | Chadwell Heath | 1930s semi-detached | RM6 straddles a boundary: Chadwell Heath addresses fall to Barking and Dagenham Council or Redbridge Council, so confirm which authority validates the structural calculation package before submitting RM6 drawings. |
| RM8 | Becontree / Dagenham | 1920s-30s estate housing (Becontree) | A structural calculation package at an RM8 address in Becontree / Dagenham is determined by Barking and Dagenham Council under its own Local Plan policies for Becontree / Dagenham. |
| RM10 | Dagenham | 1920s-30s estate housing (Becontree) | Dagenham sits wholly inside RM10, so Barking and Dagenham Council validates every structural calculation package submitted from an RM10 address. |
| IG11 | Barking | Victorian terraces, post-war flats, new-build | A structural calculation package at an IG11 address in Barking is determined by Barking and Dagenham Council under its own Local Plan policies for Barking. |
Roof pitch, wall build-up and plot depth change every few Barking and Dagenham streets, and each one changes what a structural calculation package can achieve at that address.
