Do your home improvements need planning permission?

Aug 20, 2015

Planning permission can seem like a minefield for home owners looking to make some much-needed home improvements. Here, we look at a few of the most common home improvements and whether or not they require planning permission.

With any property, it’s always best to check with your local authority if you are in any doubt about planning permission. If you live in a listed property, you may be required to apply for planning permission for any significant works.

Sheds and garages

Most sheds and garages do not require planning permission. However, there are a number of limits and conditions, including size and height, so it’s advisable to check with your local authority before undertaking any major construction.


The need for planning permission is dependent on the size of your extension, its position in relation to the house and proximity to boundaries. Once you have decided on the size and location of your extension, it’s best to check with your local authority. However, providing you are within limits, you can extend or add to your home without the need to apply for planning permission.

Windows and doors

You do not normally need planning permission for repairs, maintenance, improvements, or the insertion of new windows and doors to your property as long as they are similar in appearance to those used in the construction of the house. If you live in a listed building, you may need consent for any significant works, including windows.


A conservatory is treated the same as an extension, so there are limits and conditions that apply, including size, location and proximity to the house.

Loft conversion

Planning permission is not normally required for a loft conversion unless you are extending the roof space so that it exceeds any specified limits and conditions. Speak to your local authority if in doubt.


Planning permission is not normally required for a new or replacement staircase, although this is not always the case in listed buildings.

Bathrooms and kitchens

Planning permission is not normally required for any improvement or replacement of bathrooms and kitchens, unless you live in a listed building.

Even if you do not need planning permission, you will still need to meet building regulations for a lot of major works. These regulations are designed to ensure that the improvements meet health, safety, welfare, convenience and sustainability standards if applicable.

For further information, contact your local authority.
