Do I need planning permission for external insulation?
Planning permission may be required for external insulation if it impacts the external appearance of the building. If materials are of a similar appearance to those used in the construction of the house, then permission will likely not be required.
Listed buildings will require listed building consent for any significant work.
If you live in a Conservation Area or other protected area you will need to apply for planning permission before making changes to the outside of your house.
