Every SE27 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. SE27 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
