Do I Need Planning Permission to Replace Windows?
The short answer
Usually not, for an unlisted house replacing windows with ones of similar appearance. You may need permission for flats, where an Article 4 direction applies, for new or larger openings, or where earlier planning conditions control windows. Listed buildings need listed building consent.
