Every Tower Hamlets postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Tower Hamlets fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| E1 | Whitechapel / Spitalfields | Warehouse conversions, modern infill | A drawing package at an E1 address in Whitechapel / Spitalfields is determined by Tower Hamlets Council under its own Local Plan policies for Whitechapel / Spitalfields. |
| E1W | Wapping | Georgian terraces, warehouse conversions | E1W covers Wapping only; Tower Hamlets Council handles the drawing package, and Wapping case officers apply the E1W conservation-area map. |
| E2 | Bethnal Green | Warehouse conversions, modern infill | A drawing package in Bethnal Green may land with Tower Hamlets Council or Hackney Council — E2 crosses the boundary, and the E2 policies map decides it street by street. |
| E3 | Bow | Victorian terraces, Georgian fragments | E3 covers Bow only; Tower Hamlets Council handles the drawing package, and Bow case officers apply the E3 conservation-area map. |
| E14 | Canary Wharf / Poplar / Limehouse | Modern apartments | E14 covers Canary Wharf / Poplar / Limehouse only; Tower Hamlets Council handles the drawing package, and Canary Wharf / Poplar / Limehouse case officers apply the E14 conservation-area map. |
Roof pitch, wall build-up and plot depth change every few Tower Hamlets streets, and each one changes what a drawing package can achieve at that address.
How designation changes a Tower Hamlets drawing package: Tower Hamlets Council maintains 58 conservation areas, including Whitechapel Market, Fournier Street, Tredegar Square. Inside any of them a Tower Hamlets drawing package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Whitechapel Market sets the tone for Tower Hamlets casework.
What Article 4 removes near Tower Hamlets: Article 4 for HMOs borough-wide; additional Article 4 covering office-to-residential in Canary Wharf and City Fringe. Before pricing a drawing package we check whether the E1 address is inside the mapped area, because Tower Hamlets Council draws the Tower Hamlets boundary street by street rather than across the whole of Tower Hamlets.
The building fabric around Tower Hamlets: Georgian in Spitalfields and Wapping; Victorian industrial conversions; extensive post-war social housing; modern high-density towers in Canary Wharf and Aldgate. High heritage value in pockets (Spitalfields, Wapping), mixed with substantial regeneration areas; active planning committee. A drawing package in Tower Hamlets 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 Tower Hamlets Council.

Over the 12 quarters from 2023 Q2 to 2026 Q1, Tower Hamlets decided 563 householder planning applications and approved 87.0% of them — 4.0 percentage points above the London average of 83%. That places Tower Hamlets 10th of 32 London boroughs on householder approval rate. These are decisions the council reported to MHCLG, not our own sample.
| Measure | Tower Hamlets | Context |
|---|---|---|
| Householder applications decided | 563 | 77,680 across London |
| Householder approval rate | 87.0% | 83% London average |
| Decided within 8 weeks | 90.9% | 23rd fastest of 32 boroughs |
| Took longer than 13 weeks | 2.7% | the applications that overran the statutory target |
| Minor dwellings approval rate | 53.9% | new-build and conversion schemes under 10 units |
| All application types | 81.5% | across 2,873 decisions |
| Certificates of lawfulness issued | 399 | confirmations that work was permitted development |
Speed matters as much as the odds. Tower Hamlets decided 90.9% of householder applications inside the eight-week statutory period and let 2.7% 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.
