Every Enfield postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Enfield fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| N21 | Winchmore Hill | Edwardian villas, 1930s semi-detached | Winchmore Hill sits wholly inside N21, so Enfield Council validates every drawing package submitted from an N21 address. |
| 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. |
| EN2 | Enfield / Forty Hill | Georgian fragments, 1930s semi-detached | EN2 covers Enfield / Forty Hill only; Enfield Council handles the drawing package, and Enfield / Forty Hill case officers apply the EN2 conservation-area map. |
| EN3 | Ponders End / Brimsdown | Post-war estates, Victorian terraces | A drawing package at an EN3 address in Ponders End / Brimsdown is determined by Enfield Council under its own Local Plan policies for Ponders End / Brimsdown. |
| N11 | New Southgate / Bounds Green | Edwardian villas in Palmers Green and Winchmore Hill; 1930s semi-detached in Southgate; Victorian terraces in Edmonton; Metropolitan Green Belt north of the borough | New Southgate / Bounds Green is split at N11. Either Barnet Council or Enfield Council can determine a drawing package here, so the N11 address is checked against both policies maps first. |
| EN4 | East Barnet / Cockfosters | Edwardian villas in Palmers Green and Winchmore Hill; 1930s semi-detached in Southgate; Victorian terraces in Edmonton; Metropolitan Green Belt north of the borough | EN4 straddles a boundary: East Barnet / Cockfosters addresses fall to Barnet Council or Enfield Council, so confirm which authority validates the drawing package before submitting EN4 drawings. |
| N9 | Lower Edmonton | Victorian terraces, post-war estates | Lower Edmonton sits wholly inside N9, so Enfield Council validates every drawing package submitted from an N9 address. |
| N13 | Palmers Green | Edwardian villas, 1930s semi-detached | Palmers Green sits wholly inside N13, so Enfield Council validates every drawing package submitted from an N13 address. |
Roof pitch, wall build-up and plot depth change every few Enfield streets, and each one changes what a drawing package can achieve at that address.
Conservation areas covering Enfield: Enfield Council runs 22, and Bush Hill Park, Forty Hill, Enfield Town are the ones Enfield owners meet most. A drawing package inside a Enfield conservation area loses permitted development, so the Enfield submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Forty Hill a drawing package is judged on the street elevation first.
No blanket Article 4 over Enfield: Enfield Council has not withdrawn permitted development across Enfield, so a drawing package outside a Enfield conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a N9 owner wants on file.
The building fabric around Enfield: Edwardian villas in Palmers Green and Winchmore Hill; 1930s semi-detached in Southgate; Victorian terraces in Edmonton; Metropolitan Green Belt north of the borough. Outer north London; Metropolitan Green Belt affects north; generally permissive elsewhere. A drawing package in Enfield is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Enfield Council.

Over the 12 quarters from 2023 Q2 to 2026 Q1, Enfield decided 2,814 householder planning applications and approved 77.8% of them — 5.2 percentage points below the London average of 83%. That places Enfield 27th of 32 London boroughs on householder approval rate. These are decisions the council reported to MHCLG, not our own sample.
| Measure | Enfield | Context |
|---|---|---|
| Householder applications decided | 2,814 | 77,680 across London |
| Householder approval rate | 77.8% | 83% London average |
| Decided within 8 weeks | 91.0% | 21st fastest of 32 boroughs |
| Took longer than 13 weeks | 2.6% | the applications that overran the statutory target |
| Minor dwellings approval rate | 55.9% | new-build and conversion schemes under 10 units |
| All application types | 73.4% | across 5,493 decisions |
| Certificates of lawfulness issued | 1,810 | confirmations that work was permitted development |
Speed matters as much as the odds. Enfield decided 91.0% of householder applications inside the eight-week statutory period and let 2.6% run past thirteen weeks. A drawing package that is complete and correctly described at validation is the part of that timeline you control; the rest belongs to the council's caseload.
