What is a Dropped Kerb?

A dropped kerb (also called a vehicle crossover or vehicular access) is where the kerb between the road and pavement is lowered to allow vehicles to drive over it onto a driveway. It also usually involves raising the level of the pavement or installing a hardened crossing surface to take vehicle loads.

Dropped kerbs are essential for any driveway that requires vehicles to cross a pavement. Driving over a normal kerb is illegal and can damage both the kerb and vehicle.

Do You Need Permission?

Yes. A dropped kerb always requires permission from the local highways authority — regardless of whether your driveway needs planning permission. This is because the highway (including the pavement) is public land maintained by the council.

In some areas, the council also requires a separate planning application for a vehicle crossover before they will approve the highways works. Check with your local authority — requirements vary.

The Highways Authority Application Process

The application process typically works as follows:

1. Apply online through your council’s website. You’ll need the address, details of the proposed access, and usually a site plan.
2. Assessment. The highways authority will assess the application for sight lines, proximity to junctions (crossovers within 10m of a junction are often refused), road safety, and impact on existing street infrastructure.
3. Approval or refusal. If approved, the council will carry out the works themselves or approve your use of a council-approved contractor.
4. Works carried out. The actual installation is done by the council or their approved contractor.

Planning Permission vs Highways Approval

How Much Does a Dropped Kerb Cost?

When Applications Are Refused

Common grounds for refusal: within 10m of a road junction; poor sight lines; classified road; pavement too narrow; insufficient space on property to park clear of pavement. If refused, you can appeal or modify the proposal.

Illegal Dropped Kerbs

An illegal dropped kerb is one installed without highways authority approval. If you have an existing unapproved crossover, you may be required to reinstate the kerb at your own expense. The council can also issue an enforcement notice. Check approval status when buying a property.
