Insulation

Planning Permission

Planning permission is not normally required for fitting insulation.

External wall insulation

External wall insulation does not require planning permission providing it does not project from the wall of the house by more than 16cm.

However, if the building is listed or is in a conservation area you should consult your local planning authority.
