In short: Planning applications in Southwark are submitted through the national Planning Portal and then appear on Southwark Council's online planning register, where you can track progress and comments. Policies come from the Southwark Plan and the London Plan. Many streets in Southwark are in conservation areas, which tightens what you can do without permission.
From idea to decision
| 1 | Check if you need permission Some works are permitted development, but flats, listed buildings and conservation areas have tighter rules. |
| 2 | Pre-application advice For anything significant, Southwark Council's pre-application service can save time and money. |
| 3 | Prepare and submit Drawings and supporting documents, submitted with the fee via the national Planning Portal. |
| 4 | Consultation Neighbours and consultees can comment, normally for 21 days. |
| 5 | Decision Targets are 8 weeks for most minor and householder applications, 13 weeks for major schemes. |
| Project | Likely route in Southwark |
|---|---|
| Rear extension or loft on a house | Permitted development (consider a Lawful Development Certificate) or householder planning |
| Any external change to a flat | Full planning permission |
| Works in a conservation area | More likely to need permission; check Article 4 directions |
| Converting a house into flats | Full planning; policy protects family homes |
| Small HMO conversion | Check whether permitted development rights have been removed |
| Shopfront or signage | Planning and/or advertisement consent |
Always check with the council or a planning consultant before starting work.
