What is planning permission for driveways?
Planning permission is required in England when a new impermeable driveway or front garden surface exceeds 5 square metres, unless porous alternatives like permeable paving are used instead.
UK planning law treats front garden driveway resurfacing differently depending on the finished surface area and permeability. Homeowners can lay or replace an impermeable surface (concrete, asphalt, tarmac, or solid paving) up to 5 square metres without planning consent under permitted development rights. This means a typical small driveway replacement does not automatically require a formal application to the local council.
Once a proposed impermeable surface exceeds 5 square metres, planning permission becomes mandatory. This threshold exists because large, hard surfaces contribute to surface water runoff, which increases flood risk and can overwhelm drainage systems. Councils use this rule to manage environmental impact in residential areas.
The rule has an important exception: if the surface is porous or permeable (water can drain through it), the 5 square metre limit does not apply. Many driveway paving contractors now offer permeable alternatives like gravel, permeable asphalt, or porous block paving specifically to avoid triggering the planning requirement. The same rules apply to front forecourts, parking areas, and similar hard surfaces in domestic front gardens.
Local planning authorities in areas like Cheltenham enforce this rule, and breaching it by laying an unauthorised surface can result in enforcement action. It is worth checking with your local council whether any additional local policies apply, as some areas have stricter requirements.
