If a building is either Grade I or II Listed, or falls within a conservation area, then exemptions apply. However, the window does still have to show an improvement in energy efficiency; providing the changes do not alter the character or appearance of the building. This means that our draught-proofing system, Ventrolla’s Perimeter Sealing System (VPSS), is the ideal solution.
As with Listed Buildings, we have a vast experience of working with all properties that have permitted development restrictions. We can offer the same level of advice and service in these instances with our window renovation service, helping to liaise with the planning officers, providing detailed quotes and specifications to support your planning case for window renovation.
