Which postcode districts around Hackney do we cover for side return work?

Every Hackney postcode district we draw in, the stock that dominates it and the authority that validates a side return there. Hackney fees below are the statutory England rates for 2026, not side return estimates.

PostcodeAreaDominant stockWhat it means for a side return
N16Stoke Newington / Stamford HillGeorgian and Victorian terracesN16 straddles a boundary: Stoke Newington / Stamford Hill addresses fall to Hackney Council or Islington Council, so confirm which authority validates the side return before submitting N16 drawings.
E5ClaptonVictorian terraces, mansion blocksClapton sits wholly inside E5, so Hackney Council validates every side return submitted from an E5 address.
E8Hackney Central / Dalston / London FieldsVictorian terraces, post-war flatsHackney Central / Dalston / London Fields sits wholly inside E8, so Hackney Council validates every side return submitted from an E8 address.
E9Homerton / Hackney WickVictorian terraces, post-war estatesE9 covers Homerton / Hackney Wick only; Hackney Council handles the side return, and Homerton / Hackney Wick case officers apply the E9 conservation-area map.
EC2AShoreditchWarehouse conversions, modern infillShoreditch is split at EC2A. Either Hackney Council or City of London Corporation can determine a side return here, so the EC2A address is checked against both policies maps first.
N1Islington / HoxtonGeorgian and early Victorian terracesA side return in Islington / Hoxton may land with Islington Council or Hackney Council — N1 crosses the boundary, and the N1 policies map decides it street by street.
N4Finsbury Park / Stroud GreenVictorian terraces, post-war estatesFinsbury Park / Stroud Green is split at N4. Either Haringey Council or Islington Council or Hackney Council can determine a side return here, so the N4 address is checked against both policies maps first.
E2Bethnal GreenWarehouse conversions, modern infillA side return 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.

How does a side return differ street by street across Hackney?

Roof pitch, wall build-up and plot depth change every few Hackney streets, and each one changes what a side return can achieve at that address.

What local planning policy applies to a side return in Hackney?

How designation changes a Hackney side return: Hackney Council maintains 29 conservation areas, including Clapton, De Beauvoir Town, Stoke Newington. Inside any of them a Hackney side return cannot rely on permitted development, and the route becomes a £258 householder application determined in 8 weeks rather than a £120 prior approval in 6 weeks. Stoke Newington sets the tone for Hackney casework.

What Article 4 removes near Hackney: Article 4 Direction covers HMO conversions borough-wide and office-to-residential in specific commercial zones. Before pricing a side return we check whether the N16 address is inside the mapped area, because Hackney Council draws the Hackney boundary street by street rather than across the whole of Hackney.

Hackney housing stock: Victorian terraces dominate; large post-war estates around Hackney Wick; Georgian fragments in De Beauvoir and Stoke Newington; new-build around the Olympic Park. Young demographic; high design-quality bar in planning; mansards routinely approved in rear-of-terrace positions within conservation areas following the Hackney design guide. Read that before choosing a side return route in Hackney — construction, not postcode, sets what is achievable. Side returns in Hackney start at £1,225 on a fixed fee, or £1,750 for the Complete package covering both Hackney Council submissions.
