Which postcode districts around Croydon do we cover for conservation area application work?
Designation in Croydon is patchy rather than pervasive, and the patches sit at the two ends of the borough: the Victorian hill villas around Crystal Palace and Upper Norwood in the north, the older village cores at Purley, Coulsdon and Addington in the south. The table below gives, for each postcode district, the building stock the case officer will be looking at and the authority that validates the application — which on SE19, SE20 and SW16 is not always Croydon. The fees are the statutory England rates for 2026, not an estimate for the work.
| Postcode | Area | Dominant stock | What it means for a conservation area application |
|---|
| SE19 | Upper Norwood / Crystal Palace | Victorian villas, Edwardian terraces | SE19 is the awkward one. Upper Norwood and Crystal Palace addresses divide between Croydon and Lambeth, with only a little over half the district's recorded property sales on the Croydon side, so check the policies map before assuming who reads your heritage case. |
| SE25 | South Norwood / Selhurst | Victorian terraces | SE25 sits wholly in Croydon, taking in South Norwood and Selhurst, and the case officer works from the borough's own designation boundaries for that district. |
| CR0 | Croydon / Addiscombe / Shirley | Edwardian terraces, post-war flats | Croydon / Addiscombe / Shirley sits wholly inside CR0, so Croydon Council validates every conservation area application submitted from an CR0 address. |
| CR2 | South Croydon | Upper Norwood and Crystal Palace are Victorian villa country; Thornton Heath and Selhurst run to Edwardian terraces; Purley and Coulsdon are 1930s semi-detached; the centre is largely post-war. Pre-1900 dwellings account for 19.2% of the borough's 168,250 homes at 31 March 2025 (VOA CTSOP4.1). | CR2 is South Croydon and nothing else, so the borough validates every conservation-area application from it and applies the CR2 designation boundaries directly. |
| CR5 | Coulsdon | 1930s semi-detached | A conservation area application at an CR5 address in Coulsdon is determined by Croydon Council under its own Local Plan policies for Coulsdon. |
| CR7 | Thornton Heath | Edwardian terraces | CR7 covers Thornton Heath and nothing beyond it: Edwardian terrace stock, and a Croydon Council decision on each conservation-area application arising from that district. |
| CR8 | Purley | 1930s semi-detached, Edwardian villas | Purley falls entirely inside CR8, so the borough validates every conservation-area application there and reads each one against the Purley designation boundary. |
| SE20 | Anerley / Penge | Victorian and Edwardian terraces | SE20 covers Anerley and Penge and is divided between Bromley and Croydon. Both policies maps get tested against the address before a conservation-area application is drafted for it. |
Which Croydon neighbourhoods suit a conservation area application best?
Inside a designation the question stops being what the Order permits and becomes what the character appraisal for that specific area describes as its character. Croydon's appraisals are not interchangeable: the one written for a hillside of detached Victorian villas is asking about setting, boundary walls and the gaps between buildings, while the one written for a terraced village core is asking about frontage rhythm, roof line and shopfront survival. The neighbourhoods below are grouped by which of those conversations you are about to have.
- Purley (CR8) — conservation area application work in Purley means 1930s semi-detached, edwardian villas. Purley is 1930s semi-detached, Edwardian villas. Edwardian houses here typically need the same householder set plus a roof plan where a dormer is proposed throughout CR8. Croydon Council decides the Purley application, and Purley Way anchors the Purley location plan.
- Coulsdon (CR5) — 1930s semi-detached, Edwardian villas defines Coulsdon, where 1930s semi-detached set what a conservation area application can do. On these 1930s semis the prior approval route often replaces a full application across CR5. Any Coulsdon conservation area application is validated by Croydon Council, with Coulsdon South the usual Coulsdon reference point on the site plan.
- Addiscombe (CR0) — a conservation area application in Addiscombe starts from edwardian terraces, and Addiscombe reads as Edwardian terraces. Edwardian houses here typically need the same householder set plus a roof plan where a dormer is proposed in CR0. Croydon Council assesses Addiscombe conservation area applications against its own Addiscombe character guidance, and the location plan we draw for Addiscombe references Addiscombe Road.
- Shirley (CR0) — a conservation area application in Shirley starts from 1930s semi-detached, and Shirley reads as 1930s semi-detached. On these 1930s semis the prior approval route often replaces a full application in CR0. Croydon Council assesses Shirley conservation area applications against its own Shirley character guidance, and the location plan we draw for Shirley references Shirley Park.
- Selhurst (SE25) — a conservation area application in Selhurst starts from edwardian terraces, and Selhurst reads as Edwardian terraces. Edwardian houses here typically need the same householder set plus a roof plan where a dormer is proposed in SE25. Croydon Council assesses Selhurst conservation area applications against its own Selhurst character guidance, and the location plan we draw for Selhurst references Selhurst Park.
- Croydon (CR0) — conservation area application work in Croydon means edwardian terraces, post-war flats. Croydon is post-war centre, Edwardian residential ring. Edwardian houses here typically need the same householder set plus a roof plan where a dormer is proposed throughout CR0. Croydon Council decides the Croydon application, and Whitgift Centre anchors the Croydon location plan.
- Crystal Palace (SE19) — Victorian villas, hill character defines Crystal Palace, where victorian villas, edwardian terraces set what a conservation area application can do. Most applications on these Victorian streets are householder applications validated on existing and proposed plans across SE19. Any Crystal Palace conservation area application is validated by Croydon Council, with Crystal Palace Park the usual Crystal Palace reference point on the site plan.
What local planning policy applies to a conservation area application in Croydon?
How many, and how much ground they cover: the national register at planning.data.gov.uk lists 20 conservation areas in Croydon covering roughly 422 hectares of a borough of 8,650 — about five per cent of the land. Croydon Council publishes a higher figure of 24. Both were retrieved on 1 September 2026 and the divergence is normal, since councils count amendments and extensions differently from the register. Worth knowing that no Croydon designation in the register carries a designation date, so if you need to establish when a boundary was drawn — which matters when an alteration predates it — the council's own records are the only source.
What designation actually removes: article 2(3) of the General Permitted Development Order withdraws Class A side extensions, cladding and Class B roof enlargement inside a conservation area. So a project that would have been a £249 prior approval in six weeks becomes a £548 householder application in eight, with a heritage statement written against the relevant appraisal attached to it. Outside the designations Croydon has made no borough-wide Article 4 direction, and a lawful development certificate at £274 is the way to put that beyond argument at the point of sale.
How the council handles heritage work: Croydon decided 38 applications to alter or extend a listed building in the twelve quarters to March 2026 and granted 28 (MHCLG planning statistics, retrieved 1 September 2026). That is a small caseload for a borough this size, which reflects how little of Croydon is listed rather than any reluctance to consent. One column on the same return needs care: Croydon reported zero applications for demolition in a conservation area in every one of the twelve quarters. A blanket zero across three years is a recording convention on this form far more often than it is a measurement, and it should not be read as evidence that consent for demolition is never sought here.
Which neighbouring authorities border Croydon?
- Bromley — the sharpest contrast of the four. Bromley holds 69 conservation areas in the national register against Croydon's 20 (retrieved 1 September 2026), so an identical Victorian villa either side of the Anerley boundary can be designated on one plot and undesignated on the other. Establish the authority before the design, not after.
- Lambeth — the boundary crosses the middle of SE19 at Crystal Palace, splitting a single hillside of comparable villas between two heritage regimes with separate appraisals. Where a scheme sits close to that line we check the address on both policies maps before quoting, because the applicable appraisal is the document the application argues against.
- Sutton — runs along Croydon's western edge past Wallington and Beddington. Similar interwar and Edwardian stock to south Croydon, so the survey and drawing work matches, but the local plan and design guidance a heritage application is assessed under are Sutton's own.
- Merton — meets Croydon at Norbury and Pollards Hill inside SW16, a district that also touches Lambeth and Wandsworth. Four authorities can take an application from that postcode, and the map settles it street by street rather than by prefix.
