Do I Need Planning Permission for a Driveway?

Whether you need planning permission for a driveway depends mainly on the surface material and the drainage it provides. Permeable surfaces — and non-permeable surfaces where rainwater drains to a lawn or border — usually do not need planning permission. Non-permeable hardstanding of more than 5 square metres in the front garden does need planning permission, because of the surface water drainage impact. Rear and side driveways follow the normal outbuilding and hardstanding rules without the drainage trigger.

Since 2008, the GPDO has contained a specific rule about front garden hardstanding. Planning permission is required if you create more than 5 m² of non-permeable hardstanding in the area between the principal elevation of the house and the highway boundary, unless the surface drains rainwater to a permeable surface within the curtilage of the property.

5 m² is a very small area — roughly 2.5 m × 2 m — so most full driveways exceed this threshold. This means most new front driveways using impermeable tarmac or solid concrete need planning permission. Choosing a permeable surface avoids this requirement entirely.

Key point: if you are simply resurfacing an existing driveway with the same type of material and not increasing the hardstanding area, planning permission is generally not required.

A permeable surface allows rainwater to pass through or drain away into the ground rather than running off the surface to drains or the highway. Permeable surfaces that avoid planning permission include:

• Gravel or loose aggregate: The most straightforward permeable solution. Stabilised gravel (using honeycomb grids) prevents spread onto the road and looks neater than loose gravel.
• Permeable block paving: Block pavers with permeable jointing that allows water to drain between the blocks into a sub-base. Looks identical to standard block paving when installed correctly.
• Resin-bound aggregate: An increasingly popular option — aggregate stones bound with clear resin create a smooth, permeable surface. Highly durable and low maintenance.
• Grasscrete or grass-reinforcement grids: Plastic grids filled with topsoil and grass or gravel. Green and permeable, but less durable under heavy vehicles.

Even a non-permeable surface (concrete or tarmac) avoids the planning requirement if the surface water is directed to a lawn, flower bed or soakaway within the property boundary rather than discharging to a drain or the highway. This must be a genuine drainage provision, not a nominal gesture.

• Using a permeable surface — gravel, permeable block paving, resin-bound aggregate
• Directing rainwater from a non-permeable surface to a lawn or border for natural drainage within the curtilage
• Resurfacing an existing driveway without increasing the hardstanding area
• Creating hardstanding at the rear or side of the property (normal PD rules apply, not the 5 m² front garden trigger)
• Non-permeable hardstanding totalling 5 m² or less in the front garden

• More than 5 m² of non-permeable material (concrete, solid tarmac, solid block paving) in the front garden without drainage to a permeable area
• Property is a flat or maisonette
• Listed building — separate listed building consent may also apply
• Permitted development rights removed locally by Article 4 direction
• The works involve creating or widening a vehicle access onto a classified road (A, B or C road) — this also needs Highways Act approval from the council regardless of planning

The 5 m² non-permeable threshold applies specifically to front gardens (between the house and the highway). Hardstanding at the side or rear of a house follows the general Class F.2 permitted development rules for hard surfaces within the curtilage. Rear and side hardstanding does not trigger the same drainage requirement, though good drainage practice is always advisable.

In conservation areas, the planning rules for driveways are the same as elsewhere for the 5 m² drainage threshold. However, if planning permission is required, the materials and design must respect the character of the conservation area. Many conservation areas have local design guidance recommending natural stone setts, hoggin, or gravel in preference to tarmac or modern block paving. The council's conservation officer can advise before you apply.

Even if your driveway does not need planning permission, you will need a vehicle crossover (dropped kerb) to access the highway legally. This is a separate approval process from planning permission:

• Application to the local highways authority (usually your council's highways department, not planning department)
• The council or its contractor installs the dropped kerb and new crossing to the adoptable standard
• Cost: typically £1,000–£3,000 depending on the distance from the kerb to your boundary and ground conditions
• Approval can be refused if visibility splays are inadequate (you cannot see safely along the road) or if the crossing creates road safety risks
• Using a driveway that crosses a raised kerb without a vehicle crossover is illegal and can result in enforcement action

On A roads or classified roads, a vehicle crossover requires a separate Highways Act consent that is assessed for safety. It may also trigger a planning application for the access.

The rules about permeable driveways exist because front garden paving has been a significant contributor to urban flooding. When millions of front gardens are paved impermeable, rainwater hits the road rather than soaking into the ground, overwhelming drainage systems in heavy rainfall. Sustainable drainage (SuDS) approaches encourage rainwater to infiltrate or be held on site. Beyond planning rules, using permeable surfaces protects your own property from flood risk and is better for the environment.

Gravel driveway (supplied and installed, simple): £30–£60 per m². Resin-bound aggregate: £60–£100 per m². Permeable block paving: £50–£90 per m². Standard tarmac (non-permeable): £30–£60 per m². A typical driveway of 25 m²: £750–£2,500 (gravel) to £1,500–£2,500 (resin-bound). Dropped kerb installation: £1,000–£3,000. Planning fee if required: £258.

Can I use tarmac without planning permission? Only if you direct the surface water to a permeable area within your property (a lawn, border, or soakaway), or if the total tarmac area in the front garden is 5 m² or less. Otherwise, planning permission is required.

Does resurfacing need planning permission? Generally not, if you are simply replacing the existing surface material without increasing the area. Changing from a permeable surface to a non-permeable one may trigger the planning requirement if the new area exceeds 5 m².

Do I need planning permission to widen my driveway? If the additional area is non-permeable and more than 5 m² in the front garden without drainage to a lawn, yes. A permeable extension can avoid this.

Is a dropped kerb different from a planning application? Yes, entirely. A vehicle crossover application goes to the highways authority. A planning application goes to the planning department. You may need both, either, or neither depending on your specific situation.
