Performance rating out of 100, based on approval rate, decision speed and appeal outcomes

Lambeth is a London planning authority that covers a diverse area of the capital with a generally positive approach to householder applications. The council approves around 4 out of 5 planning applications, showing a reasonable willingness to support homeowner projects. One thing to be aware of is that decision times can be a bit slower than the target, so patience is needed when waiting for a response.

What to Expect

When you submit a planning application to Lambeth, you have a good chance of getting approval, with 83% of householder applications being granted. However, you should be prepared for the possibility that your application might take longer than the standard 8 weeks to be decided, as only 61% are processed within this timeframe. Even if your application is refused, there is still hope, as around 1 in 3 refused applications succeed on appeal. Overall, it is worth submitting if you believe your project is reasonable, but do factor in some extra waiting time to your plans.

Local Planning Considerations

London has many conservation areas and listed buildings, and Lambeth is no exception, so if your property is in a protected area you will face stricter rules about what changes you can make. You should also check whether your home is affected by any Article 4 directions, which remove certain permitted development rights and mean you need planning permission for works that would normally be allowed. Looking at your specific street and neighbourhood early on will save you time and help you understand what is and is not likely to be acceptable.

Tips for Homeowners

Start by getting clear advice about whether your project even needs planning permission, as some smaller works benefit from permitted development rights and can go ahead without an application. Take time to prepare a really thorough and professional application with good quality drawings and photographs, as this helps the council understand your proposal and can speed up decision making. Consider engaging with your neighbours early and thinking about any concerns they might raise, as this can help you refine your plans and reduce the chance of objections. Finally, given that decisions can take longer than 8 weeks here, submit your application well in advance of when you actually want to start work, rather than hoping for a quick turnaround.

About the performance rating: The score out of 100 is calculated from three factors: householder application approval rate (up to 40 points), the percentage of decisions made within the 8-week statutory target (up to 30 points), and the appeal overturn rate, where a lower rate means the authority makes sound decisions that hold up on appeal (up to 20 points). A further 10 points are available for data completeness. Source: MHCLG PS2 planning statistics and Planning Inspectorate appeal decisions, 2025 Q1-Q4.
