Often Asked Questions (FAQ)1. Do I require planning consent to recondition my sash windows?
In many cases, standard repairs and draught-proofing do not require preparation consent. Nevertheless, if your property is "Listed," you need to consult your Local Planning Authority (LPA) before altering the glazing (e.g., from single to double glazing).
