Islington
Average
Performance rating out of 100, based on approval rate, decision speed and appeal outcomes
Islington is a London borough with a good track record of approving householder planning applications, with 93% of applications getting the green light. The council takes a generally supportive approach to home improvements and extensions, though like all London authorities it needs to balance growth with protecting the character of its neighbourhoods. What makes Islington distinctive is its large number of conservation areas and listed buildings, which means many homeowners need to think carefully about how their plans fit with local heritage.

What to Expect
When you submit a planning application to Islington, you have a strong chance of approval: 93% of householder applications are granted. However, you should be prepared for a longer wait than the standard 8 weeks, as only 43% of applications are decided within this target timeframe. This doesn't mean your application is at risk, just that the council may need extra time to assess your plans properly. If your application is refused, you have a reasonable chance of success on appeal, with 23% of refused applications overturned at appeal, so it's not necessarily the end of the road.
Local Planning Considerations
Islington has extensive conservation areas across the borough, and many properties are listed buildings, which means any external changes or alterations may need conservation area consent or listed building consent on top of planning permission. You should check whether your property falls within a conservation area or is listed before you design your project, as this will significantly affect what you can do. The council is also protective of green space and trees, so any plans that involve removing mature vegetation or affecting gardens may face closer scrutiny.
Tips for Homeowners
Start by finding out whether your property is in a conservation area or listed, as this will shape your entire approach and may mean you need specialist advice alongside your planning application. Take time to understand the character of your street and neighbourhood, then design your extension or alteration to complement what's already there rather than stand out from it, as this approach tends to sit well with Islington's planning officers. Because the council takes longer than average to make decisions, submit your application well in advance of any deadlines you have in mind, and consider asking an agent to help navigate the process, particularly if your property has heritage restrictions.
