Most new driveways in London don’t need planning permission. But “most” is doing a lot of work in that sentence. Whether yours does depends on three things: the surface you choose, where the rainwater goes, and how cars will get onto it from the road.
Get those right at the design stage and you usually avoid an application altogether. Get them wrong and you could be asked to rip the driveway up. This guide walks through the checks we run before any front-garden driveway in Barnet, Harrow, Brent or Camden.
The short answer
According to the Planning Portal, you don’t need planning permission for a new or replacement front-garden driveway of any size if it uses a permeable surface, or if rainwater runs off onto a lawn or border where it can soak away.
You do need permission if the driveway covers more than 5 square metres with a traditional impermeable surface and the water has nowhere to drain except the street.
The rule exists to cut flood risk. Every front garden paved with a sealed surface sends more water into drains that, in much of London, were never sized for it.
Check 1: Is the surface permeable?
This is the decision that matters most, and you control it.
Permeable options let water pass through the surface into a specially built sub-base below:
- Permeable block paving (blocks with wider joints filled with grit rather than sand)
- Resin-bound gravel laid on a porous base
- Porous asphalt
- Gravel, set in a stabilising grid so it doesn’t migrate
Impermeable options shed water off the surface:
- Standard block paving with sand joints
- Conventional tarmac
- Plain or imprinted concrete
- Most natural stone and porcelain laid on mortar
One catch people miss: a permeable surface only works if the sub-base is built for it. Lay permeable blocks on a standard compacted base and you’ve paid for a permeable driveway that doesn’t drain. Ask any contractor what goes underneath, not just on top.
Check 2: If it’s impermeable, where does the water go?
You can still use an impermeable finish without permission if the run-off is directed to a permeable area within your own property. In practice that means:
- Laying the driveway with a gentle crossfall towards a planted bed or lawn
- Adding a soakaway or drainage channel that discharges into the ground, not the public sewer
- Combining a block-paved driveway with a permeable strip or border
What you can’t do is fall the whole surface towards the pavement. Water running onto the highway is exactly what the rules are designed to stop. We cover drainage design in more detail on our drainage and features page and in our post on why drainage matters in tarmac driveway installation.
Check 3: Do the usual allowances apply to your home?
The permitted development allowances described above apply to houses. The Planning Portal is clear that they don’t automatically apply:
- To flats and maisonettes
- Where a planning condition or an Article 4 Direction removes permitted development rights
- Where other local restrictions apply
Much of North and North West London is covered by conservation areas, and some streets carry Article 4 Directions. If you’re in one, phone your council’s planning duty officer before you commit to a design. It is a quick conversation that can save months.
The front-garden rules also only cover the paved surface. New walls, fences, gates or pillars can have their own height limits and may need separate permission.
Check 4: How will the car get onto it?
This is the step people often leave until last, and it trips up a surprising number of projects.
If you need to drive over the pavement to reach your new driveway, you need a dropped kerb, also called a vehicle crossover. This is a highways matter, separate from planning.
Barnet Council is a good example of how it works in our area:
- Only the council can build the crossover. Altering the public footway yourself, or having a private contractor do it, is an offence.
- You apply online, and fees depend on things like the size of the proposed crossover.
- If the council is already planning footway works on your street, applying at that point may reduce the cost.
Other boroughs run similar schemes with their own criteria, such as minimum front-garden depth and the position of trees, lamp posts and drains. On a classified road, planning permission is often needed for the access as well.
The practical advice: apply for the crossover before you build the driveway. If it’s refused, a driveway with no legal way to drive onto it isn’t much use.
Putting it together: a simple order of work
- Check whether you’re in a conservation area or under an Article 4 Direction.
- Choose a surface and drainage approach that avoids the need for permission where possible.
- Apply for the dropped kerb and wait for approval.
- Build the driveway to the agreed design, with the right sub-base.
- Keep paperwork: product specs and drainage details are handy when you sell.
What we do for our clients
At Stonecraft Landscapes we design every driveway around these rules from the first site survey, so the surface, levels and drainage work for both the planning side and the look you want. If you’re weighing up materials, our comparison of resin, block paving and tarmac is a good next read.

FAQs
Can I replace my existing tarmac driveway without planning permission?
The same rules apply to replacements as to new driveways. A like-for-like impermeable surface over 5 m² that drains to the road would need permission, so most replacements are designed to be permeable or drain to a border.
Does a gravel driveway need planning permission?
Gravel is permeable, so it doesn’t normally need permission on a house’s front garden. Some councils restrict loose gravel close to the highway because it spreads onto the pavement, so a stabilising grid or resin-bound finish near the road is worth considering.
