Every W10 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. W10 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| W10 | North Kensington / Ladbroke Grove | Victorian terraces, post-war estates | A drawing package at an W10 address in North Kensington / Ladbroke Grove is determined by RBKC Planning under its own Local Plan policies for North Kensington / Ladbroke Grove. |
