Which Barking and Dagenham postcodes does this structural calculation package service cover?
Below are the Barking and Dagenham postcode districts we work in, the housing each is built from, and the council that validates a submission there. Worth knowing where you are submitting: on MHCLG's returns for the twelve quarters to March 2026, the borough granted 863 of 1,239 householder applications and refused 376 - 69.7% approved, against 83.0% for the 33 boroughs pooled. That is thirteen points harder than the London average, and it is an argument for calculations and drawings that leave a case officer nothing to query. Where a pound figure appears in the table it is the nationally set 2026 planning application fee, and it has nothing to do with what calculations cost. Source: MHCLG live planning statistics.
| 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) | Becontree and Dagenham, RM8. Barking and Dagenham Council applies its own Local Plan here. The Becontree estate is the dominant stock, and cottage-estate construction of that period behaves predictably - which makes the calculations straightforward and the assumptions worth verifying anyway. |
| RM10 | Dagenham | 1920s-30s estate housing (Becontree) | RM10, covering Dagenham. Barking and Dagenham Council validates everything submitted from the district. Inter-war housing predominates, meaning shallow foundations and cavity walls are the usual starting point for a rear opening. |
| IG11 | Barking | Victorian terraces, post-war flats, new-build | Barking itself, IG11. The council determines applications from IG11 under its Local Plan. Stock is more mixed here than on the estates, so the survey does more work before the engineer starts. |
