Front Garden Driveways: The Permeable Paving Rules (UK)
The short version
Since 2008, paving over more than 5m² of your front garden with an impermeable surface needs planning permission — unless rainwater drains to a permeable area on your own land. Choose a permeable surface and you can usually just get on with it.
Why the rule exists
Front gardens used to soak up rain; paved, they dump it into drains designed for a greener Britain. The rule pushes new driveways to shed water on their own plot — into soil, gravel or a soakaway — rather than the street.
Surfaces that comply
Gravel is the cheapest compliant option by far. Permeable block paving (wider joints filled with graded grit over an open sub-base), resin-bound gravel, porous asphalt and grass-reinforcement grids all qualify too — at higher cost.
Gravel done right
A compliant gravel drive is more than stones on soil: compacted MOT type 1 sub-base, heavy-duty membrane, then 10cm of gravel — or 3–4cm over stabilising grids for a firmer feel. Our gravel driveway calculator works out the full list, grids and membrane included.
If you want impermeable anyway
You can still lay concrete or standard block paving without permission if the run-off drains to a lawn, border or soakaway within your boundary. Only when water heads to the public drain does the 5m² rule bite. When in doubt, a quick call to your local planning office settles it.
