Guide to replacing windows in a conservation area

You’ve decided that it’s time to replace the windows in your home. But before you go ahead, you need to know if you live in a conservation area; it could mean your house is affected by special controls (called ‘Article 4 Directions’) restricting any work that you can normally do without planning permission from your local planning authority, such as replacing a door or window.

These restrictions could also limit the style of your new windows, and the materials used, all adding to the expense.    

What is a conservation area?

Conservation areas exist to protect and retain the special architectural and historic characteristics of a unique area of historical significance. They restrict the scope of permitted development rights, either in relation to a particular area or site, or a particular type of development anywhere in the local authority’s area

What is the purpose of a conservation area?

Having somewhere designated a conservation area is to prevent anyone from developing a modern building, or altering an existing one, so it’s out of character with the surrounding structures.

Windows are the defining feature and focal point of any building and the type of window installed can improve or completely ruin the look of a building, which is important in conservation areas or listed buildings.

You may be surprised to learn that there are over 10,000 conservation areas in England, and every local authority has at least one conservation area in its care.

Is my house in a conservation area? 

To find out if you live in a conservation area and what, if any, restrictions exist that could affect you, you’ll need to contact your local planning authority (LPA), who will be able to tell you when your particular conservation area was created, how far it extends, why it was created, and the level of legal protection it has in place.
