Which postcode districts around Islington do we cover for conservation area application work?
Islington is small and dense — 1,486 hectares, 93.4% of it built on, the highest developed share of any London borough — so the district you are in tells you more about the age of the fabric than about which council you file with. Fees named below are the statutory England rates for 2026, not our charges for the drawings.
| Postcode | Area | Dominant stock | What it means for a conservation area application |
|---|
| EC1R | Clerkenwell / Exmouth Market | Georgian and early Victorian terraces | Clerkenwell / Exmouth Market sits wholly inside EC1R, so Islington Council validates every conservation area application submitted from an EC1R address. |
| EC1V | City Road / Old Street | Georgian and early Victorian terraces | A conservation area application at an EC1V address in City Road / Old Street is determined by Islington Council under its own Local Plan policies for City Road / Old Street. |
| EC1Y | Bunhill / Whitecross | Georgian and early Victorian terraces | Bunhill / Whitecross sits wholly inside EC1Y, so Islington Council validates every conservation area application submitted from an EC1Y address. |
| N4 | Finsbury Park / Stroud Green | Victorian terraces, post-war estates | Finsbury Park / Stroud Green is split at N4. Either Haringey Council or Islington Council or Hackney Council can determine a conservation area application here, so the N4 address is checked against both policies maps first. |
| N16 | Stoke Newington / Stamford Hill | Georgian and Victorian terraces | A conservation area application in Stoke Newington / Stamford Hill may land with Hackney Council or Islington Council — N16 crosses the boundary, and the N16 policies map decides it street by street. |
| WC1X | Bloomsbury / Mount Pleasant | Georgian and early Victorian terraces | Bloomsbury / Mount Pleasant is split at WC1X. Either Camden Council or Islington Council can determine a conservation area application here, so the WC1X address is checked against both policies maps first. |
| N1 | Islington / Hoxton | Georgian and early Victorian terraces | Islington / Hoxton is split at N1. Either Islington Council or Hackney Council can determine a conservation area application here, so the N1 address is checked against both policies maps first. |
| N5 | Highbury | Victorian terraces, mansion blocks | Highbury sits wholly inside N5, so Islington Council validates every conservation area application submitted from an N5 address. |
How does a conservation area application differ street by street across Islington?
Just over a third of Islington's 112,160 homes were built before 1900 and a further 7.3% before 1919 (VOA council tax stock, 31 March 2025), but the borough also carries a large post-war and 1970s stock — 9.6% of it dates from 1973 to 1982 alone. Those two halves want completely different roof solutions, and the conservation boundary does not follow the split.
- Tufnell Park (N7, N19) — Victorian villas and terraces defines Tufnell Park, where victorian villas and terraces set what a conservation area application can do.

Does Islington planning policy restrict a conservation area application?
Conservation areas covering Islington: Islington Council runs 40, and Clerkenwell, Angel, Barnsbury are the ones Islington owners meet most. A conservation area application inside a Islington conservation area loses permitted development, so the Islington submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Canonbury a conservation area application is judged on the street elevation first.
Islington and Article 4: Article 4 Direction covering the whole borough removes permitted development rights for HMO conversions (C3 to C4). Separate Article 4 for office-to-residential in key areas. A conservation area application planned at a N1 address is checked against that direction first; Islington Council publishes the Islington extent, and the N1 line rarely follows the Islington boundary you would expect.
Islington housing stock: Georgian and early Victorian terraces, Victorian bye-law housing, 1930s mansion blocks, converted industrial buildings in Clerkenwell and Farringdon. Densely terraced, gentrified; strong conservation area coverage; active planning department. Read that before choosing a conservation area application route in Islington — construction, not postcode, sets what is achievable.
Who decides a conservation area application on the edge of Islington?
- Camden — adjoining Islington, with 40 conservation areas centred on NW1. A conservation area application on the far side of the Islington line is determined by Camden Council, so the Islington quote for conservation area applications is checked against Camden guidance before it is issued.

- Haringey — the Haringey boundary runs against Islington, so a conservation area application a street from Islington is decided by Haringey Council instead. Haringey runs 29 conservation areas across N4 and its neighbours, which is why conservation area applications priced for Islington are re-checked against Haringey policy whenever the Islington address sits on that edge.
