Yes, because external insulation often changes the visual appearance of the facade and the volume of the building. It is strongly recommended to contact local planning authorities before starting work to check specific requirements.
The grant application must be submitted before the renovation work begins. It is important to follow this rule to ensure your eligibility for available financial aid.
