Driveway planning permission: what homeowners actually need to know

Most driveways in England do not need planning permission. The ones that do are usually the ones where somebody laid an impermeable surface at the front of a house and let the water run onto the road — and that is avoidable at no extra cost if it is designed in from the start.

The rule, in plain terms

Since October 2008, laying more than five square metres of impermeable surface between the front of a house and the highway requires planning permission — unless the surface water is directed to a permeable area or a soakaway within the property boundary.

Three things follow from that, and they are the three most commonly misunderstood points about driveways in England.

• It only applies at the front

  The rule concerns the area between the principal elevation and the highway. A rear or side driveway is not covered by it, though other permitted development limits may apply.

• Five square metres is small

  That is roughly 2.2 metres square. Almost any real driveway exceeds it, so in practice the question is not whether you are over the threshold but whether your surface is permeable or drains to your own land.

• Draining to your own land counts

  You do not have to lay a permeable surface. A conventional surface falling to a soakaway, a border, or a gravel margin within your boundary is equally compliant.

What counts as permeable

• Gravel

  Permeable by default, with or without a stabilising grid. The simplest way to stay outside the rules entirely.

• Permeable block paving

  A specific system — wider joints filled with angular grit, over an open-graded stone sub-base. Standard block paving on sand is not permeable in this sense.

• Porous asphalt

  Open-graded macadam. Less common domestically but used as the base under resin.

• Resin bound

  Porous, provided the base beneath it drains too.

• Not permeable

  Standard block paving on sand, standard tarmac, concrete, pattern imprinted concrete, and natural stone bedded on mortar over concrete.

Choosing something from the second list is completely fine. It just means the drainage has to be designed — a soakaway, a channel drain to a soakaway, or a permeable margin along the low edge.

The dropped kerb is a separate thing

This causes more confusion than the planning rule itself. If your car crosses a public footway or verge to reach the driveway, you need a vehicle crossing, commonly called a dropped kerb. That is a highways matter, applied for through your local highway authority, and it is completely separate from planning permission.

In our area that means West Northamptonshire Council, North Northamptonshire Council, Milton Keynes City Council, Buckinghamshire Council, Bedford Borough Council, Central Bedfordshire Council or Luton Borough Council depending on where you are.

Do this first. Laying the driveway and then discovering the crossing is refused — because of a street tree, a lamp post, a bus stop, sight lines or a service chamber — is a genuinely expensive way to find out. Applications are typically assessed on road safety and on what is physically in the footway, and a refusal is not unusual.

Where extra restrictions apply

• Listed buildings

  Work affecting a listed building or its setting may need listed building consent. This includes what you lay at the front.

• Conservation areas

  Permitted development rights are often more limited. Check before ordering materials — several of the towns we cover have conservation areas covering a good share of the older housing.

• Article 4 directions

  These remove specific permitted development rights in a defined area. They are local and easy to be unaware of.

• Flats and maisonettes

  Householder permitted development rights generally do not apply, so the front-garden exemptions may not be available at all.

• New-build estates

  Planning conditions or estate covenants frequently restrict alterations, including driveways and hardstanding, regardless of national rules.

What happens if you get it wrong

Laying an impermeable driveway that drains to the highway without permission is a planning breach, and a local authority can take enforcement action requiring it to be put right. In practice enforcement is usually complaint-driven rather than proactive, but a neighbour reporting standing water or winter ice on the footway is exactly the sort of complaint that gets acted on.

There is also the practical side: run-off onto a public footway freezes, and it puts your rainwater into a highway drainage system that was not designed for it.

The straightforward route

For most homeowners the sequence is simple. Decide whether you need a dropped kerb and apply for it early. Then either choose a permeable surface, or choose whatever surface you like and put a soakaway or permeable margin on the quote. Either way you need no planning application, and the drainage costs far less designed in than retrofitted.

This is general guidance on the national rules rather than advice on your property. Local restrictions vary, and your council's planning team will confirm the position for a specific address.
