The Government’s online service for planning, the planning portal, includes advice and guidance on how to implement the new planning regulations which allow surfacing of driveways with permeable paving materials. Similar advice together with the regulations is also on the departmental website. Ultimately it is for local authorities to encourage householders to make use of permeable materials, especially where there are particular risks of surface water run off leading to flooding. Local authorities are also responsible for enforcement where the new regulations are not observed.
