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

Merton is a London planning authority in South West London that handles planning applications for residential areas across the borough. The council has a positive approach to householder applications, approving the vast majority of what comes through. One thing that stands out is that Merton is generally supportive of residential development, though like all London boroughs it does balance this with protecting local character.

What to Expect

When you submit a planning application to Merton, you have a good chance of getting approval, with 91% of householder applications being granted. However, you should be prepared for a slightly longer wait than the standard 8 weeks, as only around 62% of applications are decided within this timeframe. Most applications will take between 8 and 13 weeks, though straightforward cases may be faster. The council is generally reasonable and communicative, so staying in touch with your case officer can help things move along.

Local Planning Considerations

Merton has several conservation areas where certain types of work require planning permission that might not need it elsewhere, such as changes to roof lines or cladding. The borough also has areas within the Green Belt where development is restricted, so check your property's location before applying. Some residential roads have Article 4 directions in place which limit certain permitted development rights, so it is worth checking with the council early on.

Tips for Homeowners

Get in touch with the planning team before submitting your application, as they can point out any local sensitivities or requirements specific to your area that will help your application succeed. Make sure your drawings and supporting documents are clear and professional because Merton officers do take time to properly assess applications, and good quality information speeds things up. If your application is refused, remember that about a quarter of appeals are successful, so don't lose heart, but do try to address the council's concerns in an appeal statement.

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.
