Do I need planning permission for external wall insulation?

If the finish looks similar to the existing walls, usually not. Rendered insulation on a brick house changes its appearance, so it often does.

Can I paint my house a different colour?

Painting isn't development, so you don't need permission — unless your street is covered by an Article 4 direction that controls painting, common in conservation areas.

Cladding or rendering a house without planning permission

Cladding and renderwithout planning permission

The short answer

Only in matching materials. Re-rendering or cladding is permitted development if the finish looks similar to the existing house. Changing the look — timber cladding on brick, render over stone — needs planning permission, and in a conservation area any cladding does.
