Do I Need Planning Permission for Replacement Glazing or Extensions?

Replacing Existing Windows or Doors

Replacing existing windows and doors onto your home does not usually require planning permission.

These types of works are covered by ‘Permitted Development Rights’ where the planning consent is given automatically by Parliament rather than your local building authority.

If the replacement windows and doors you require are similar to your previous design, then these are usually covered by Permitted Development rights and therefore no planning permission will be required.

Certain sizes of extensions and conservatories are also covered by Permitted Development Rights, as long as the addition to the home complies with various rules as stated by the government.

Permitted Development Rules

The Permitted Development rules include restrictions on the size of an extension. For example, to be covered by Permitted Development Rights a new extension must not extend more than 3m from the rear of the house on an attached property, or 4m on a detached property.

Planning permission is not always needed to fit bifold or sliding doors to the rear of a home but a building notice may need to be submitted.

All new build homes will require full planning permission applications to your local authority.

Local Authorities

Different rules are applied if your home is listed, within a conservation area, an area of ‘Outstanding Natural Beauty’, or a similar protected area.

If you live in these areas and are planning to replace your windows or doors you will need to consider the Local Authorities. These have the power to remove the permitted development rights in an area where the changes made to the external face of your building could damage the character of the area.

If you have any doubts as to whether you will need planning permission to install any new windows or doors always speak to your local authority.
