Conservation areas in Kensington
What is a conservation area?
Conservation areas safeguard the built environment by applying additional oversight to building alterations. This means that planning controls are used to manage the changes that are allowed within the designated area, preserving its historic and architectural character. Living in a conservation area does not mean that your property can’t change, only that it must remain in keeping with its surroundings.
Why does Kensington have conservation areas?
Kensington is particularly proud of its historic character and is keen to ensure that this isn’t diluted or lost over time. Almost 75% of the borough falls under the protection of conservation areas.

Additional restrictions
Further restrictions can be applied if an Article 4 Direction is in place within a conservation area. This works by withdrawing permitted development rights and requiring property owners to seek planning permission instead. Here is a complete list of Article 4 Directions in Kensington. These measures are intended to control the small-scale alterations that can gradually impact the historic character of an area, such as:
- Changing front doors
- Replacing windows
- Altering boundary walls
- Works to the front elevation
- Roof alterations

We’re here to support Kensington residents with their applications for planning permission, using our expertise to handle the process on their behalf.

How long does it take to apply and gain approval within a conservation area?
When it comes to planning applications there are no set timelines. The time taken for approval can be influenced by a wide range of factors, including the backlog of submitted applications that the planning authority is dealing with. Nonetheless, we believe based on our experience that the following suggestions can work as rough guidelines:
Preparing the application – 2-3 weeks
The requirements within a conservation area can be complex, making preparation crucial. Allow several weeks to put your application together so you can be confident that your proposal meets the criteria.
Assessing the application – 8 weeks
The planning authority has 8 weeks to return a decision on your application, once it has been checked and marked as complete. This introduces a lot of flexibility as the planning officer can delay this countdown to their advantage. They may also extend the decision date if they request additional information. As an applicant, it’s important to accept this as part of the process as, unfortunately, these factors are out of your control.

What if my home is listed?
Listed buildings in Kensington and Chelsea need Listed Building Consent from the council for almost any change to their windows, on top of any planning permission. We don’t carry out work on listed buildings, so if your home is listed, speak to the council’s conservation officer first. If your home is in a conservation area but isn’t listed, we can prepare and submit the planning application for you.
