What to Expect

When you submit a householder planning application to Lambeth, you have a good chance of approval, with around 83% of applications being granted. However, you should be prepared for decisions to take a bit longer than the standard 8 weeks, as only about 61% of applications are decided within this timeframe. The council will assess your application carefully against local planning policies, and if you're refused, there's a reasonable chance of success on appeal, with about 32% of refused applications overturned. It's worth being patient and thorough with your application to help things move smoothly.

Local Planning Considerations

Lambeth contains several conservation areas where stricter rules apply to what changes you can make to your property's appearance, particularly regarding windows, doors and external materials. Parts of the borough are also subject to Article 4 directions which remove certain permitted development rights, meaning you may need planning permission for works that would normally be allowed elsewhere. Before you start any project, it's essential to check whether your property falls within a conservation area or has any special designations.

Tips for Homeowners

Start by having a clear conversation with the planning department early on about your proposals, as they can give informal guidance before you submit and may help prevent delays later. Make sure your application is as detailed and well presented as possible, with clear drawings and a thorough planning statement explaining how your scheme fits with local policies, since this can speed up the decision making process. If your property is in a conservation area or a sensitive location, consider getting professional advice or working with a planning consultant, as these applications often need extra care and attention to detail.

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.
