For most internal upgrades like attic or cavity wall insulation, you typically won't need planning permission in Laois. However, external wall insulation (EWI) is different. Laois County Council has previously indicated that EWI is not considered an exempted development and therefore often requires planning permission, especially if it significantly alters your home's appearance or if your property is a protected structure. Always consult with Laois County Council’s planning authority before commencing any external insulation work.
