Every EN1 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. EN1 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| EN1 | Enfield Town / Bush Hill Park | Georgian fragments, 1930s semi-detached | Enfield Town / Bush Hill Park sits wholly inside EN1, so Enfield Council validates every drawing package submitted from an EN1 address. |

No blanket Article 4 over EN1 (Enfield Town / Bush Hill Park): Enfield Council has not withdrawn permitted development across EN1 (Enfield Town / Bush Hill Park), so a drawing package outside a EN1 (Enfield Town / Bush Hill Park) conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a EN1 owner wants on file.
