Every Croydon postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Croydon fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| CR8 | Purley | 1930s semi-detached, Edwardian villas | A drawing package at an CR8 address in Purley is determined by Croydon Council under its own Local Plan policies for Purley. |
| SE20 | Anerley / Penge | Victorian and Edwardian terraces | A drawing package in Anerley / Penge may land with Bromley Council or Croydon Council — SE20 crosses the boundary, and the SE20 policies map decides it street by street. |
| SW16 | Streatham / Norbury | Edwardian terraces, post-war flats | SW16 straddles a boundary: Streatham / Norbury addresses fall to Lambeth Council or Wandsworth Council or Merton Council or Croydon Council, so confirm which authority validates the drawing package before submitting SW16 drawings. |
| SE19 | Upper Norwood / Crystal Palace | Victorian villas, Edwardian terraces | Upper Norwood / Crystal Palace is split at SE19. Either Croydon Council or Lambeth Council can determine a drawing package here, so the SE19 address is checked against both policies maps first. |
| SE25 | South Norwood / Selhurst | Victorian terraces | South Norwood / Selhurst sits wholly inside SE25, so Croydon Council validates every drawing package submitted from an SE25 address. |
| CR0 | Croydon / Addiscombe / Shirley | Edwardian terraces, post-war flats | CR0 covers Croydon / Addiscombe / Shirley only; Croydon Council handles the drawing package, and Croydon / Addiscombe / Shirley case officers apply the CR0 conservation-area map. |
| CR2 | South Croydon | Victorian villas in Upper Norwood and Crystal Palace; Edwardian terraces in Thornton Heath and Selhurst; 1930s semi-detached in Purley and Coulsdon; post-war in Croydon central | CR2 covers South Croydon only; Croydon Council handles the drawing package, and South Croydon case officers apply the CR2 conservation-area map. |
| CR5 | Coulsdon | 1930s semi-detached | A drawing package at an CR5 address in Coulsdon is determined by Croydon Council under its own Local Plan policies for Coulsdon. |
Roof pitch, wall build-up and plot depth change every few Croydon streets, and each one changes what a drawing package can achieve at that address.
Croydon conservation designations: there are 24 across Croydon Council, Old Coulsdon, Purley, Shirley Park among them. Designation costs a Croydon owner the permitted-development route: a drawing package then needs a £258 householder application over 8 weeks, in place of the £120 prior approval route that takes 6 weeks. Crystal Palace is the Croydon designation that most often changes a drawing package design.
Article 4 and your Croydon drawing package: Croydon Council has made no borough-wide direction, so permitted development for a drawing package in Croydon generally survives outside Croydon conservation areas and listed curtilages. A Lawful Development Certificate at £129 is how a SE19 owner records that a drawing package was lawful.
