Planning & regulations

Do I need planning permission for a driveway?

The 5m² rule, permeable surfaces and soakaways, and where the exceptions bite.

The short answer

For most homes you don't normally need planning permission to lay a driveway — but a key rule applies to the surface. If your new or replacement front driveway is over 5 square metres and you lay an impermeable surface like standard tarmac that drains to the road, planning permission is usually required. You can stay within permitted development by using a permeable surface (such as porous asphalt, gravel, permeable block paving or resin-bound) or by draining the run-off to a soakaway, border or lawn within your own boundary. The big exceptions are listed buildings and conservation areas, national parks and AONBs, where you should check with your local planning authority first.

Driveways are usually permitted development, so the question is rarely 'do I need permission to have a drive' — it's 'does my surface and drainage keep me within the rules'. Here's what the GOV.UK guidance actually says.

The rules in brief

The 5m² permeable-surfacing rule

Government guidance is clear: you can lay a hard surface in your front garden without planning permission as long as the surface is permeable, or the rainwater drains to a permeable area within your property. If the new or replacement surface is over five square metres and made of an impermeable material like standard tarmac that lets water run off onto the road, then planning permission is normally required. In practice you have two compliant routes: choose a permeable surface, or keep solid tarmac and direct the run-off to a soakaway, gravel border or lawn on your own land. Done either way, the drive stays permitted development.

SituationPermission needed?
Driveway 5m² or underNo
Over 5m², permeable surfaceNo (permitted)
Over 5m², drains to plot soakaway/borderNo (permitted)
Over 5m², impermeable, drains to roadYes — usually required

When the exceptions apply

Even where a driveway is normally permitted, some properties have tighter rules. If your home is listed, external works usually need listed building consent, and in a conservation area, national park or AONB permitted development rights can be restricted — so check with your local planning authority before starting. A dropped kerb to cross the footpath is a separate consent from the highways authority, whatever surface you choose. And remember the drainage rule applies to replacing a surface too, not just laying a brand-new one, so swapping an old impermeable drive for fresh solid tarmac can bring the SUDS rule into play.

A practical point: the rule is really about where the water goes, not the material itself. Solid tarmac is fine if the run-off drains to a soakaway or permeable border on your own land. If you'd otherwise be sending water to the road, plan that drainage in — or choose a permeable surface — to stay within permitted development.

Frequently asked questions

Do I need planning permission for a tarmac driveway?

Usually not, provided you handle drainage. If the new or replacement front driveway is over 5 square metres and uses an impermeable surface like standard tarmac that drains to the road, planning permission is normally required. Using a permeable surface, or draining run-off to a soakaway or border on your own land, keeps you within permitted development.

What is the 5 square metre driveway rule?

Under GOV.UK guidance, a new or replacement front-garden hard surface over 5m² needs planning permission if it is impermeable and drains to the road. Keep it permeable, or drain the water to a permeable area within your property, and no permission is normally needed.

Is solid tarmac allowed without permission?

Yes, as long as the rainwater drains to a soakaway, gravel border or lawn within your own boundary rather than running onto the road. If solid tarmac over 5m² would drain to the road, you'll usually need permission or a permeable alternative.
