Planning in Croydon
Checked October 2026. Planning policy changes, so we confirm the position for your address before you commit.
The Suburban Design Guide SPD (SPD2, 2019) was revoked and has not been used to decide planning applications since 26 July 2022, so extensions are assessed against Local Plan policy rather than its design rules.
SourceA borough-wide Article 4 direction has removed permitted development rights for converting a house or flat to a small HMO since 28 January 2020, so this change of use needs planning permission.
SourceThere are 21 conservation areas in Croydon.
SourceNew licensing schemes started on 1 September 2026 for five years: selective licensing in 14 of the borough's 28 wards and additional HMO licensing across the whole borough.
SourceA partial review of the Croydon Local Plan (2018) was submitted for examination on 29 November 2024; hearings ended in October 2025 and further main modifications are to go to public consultation.
