Replacement Windows

For many years it has not been necessary to apply for Building Regulation consent when replacing windows in existing dwellings, unless a structural alteration was involved. Since the 1 April 2002, all owners replacing windows need to make an application and the new windows themselves will have to fully meet the requirements of the Building regulations. So even if you are replacing only one window with one bought from a local DIY centre you still need to follow the guidance.

A guidance note on replacement windows is available to view (see below) which provides full details. The guidance note is published in PDF format and will open in a new window.
