Vehicle crossovers and section 184 consent

Dropping the kerb outside your house always needs the highway authority's consent under section 184 of the Highways Act 1980. It sometimes needs planning permission as well. Those are two separate applications to two parts of the council, decided on different tests, and getting one does not get you the other. The planning question turns almost entirely on whether the road is classified.

Driving a car over a footway or verge without a properly constructed crossing is not simply frowned upon, either. The highway authority can serve notice requiring the crossing to be built, carry out the work itself and recover the cost from the householder.

The consent you always need

Section 184 covers the physical alteration of the highway: lowering the kerb, reconstructing the footway to take vehicle loading, adjusting drainage gullies and relocating any street furniture in the way. The footway belongs to the highway authority, which is the county council in two tier areas and the unitary or borough council elsewhere.

The authority controls both the design and the execution. Some carry out all crossing works with their own contractor. Some operate an approved contractor list and inspect afterwards. Very few will let a general builder cut a kerb line unsupervised, and doing so anyway invites the authority to reinstate the footway at your expense.

Apply on the authority's own form, which will ask for the frontage dimensions, the proposed crossing width, photographs and a location plan. Expect a site inspection.

When planning permission is also needed

The formation of a means of access to a highway is development. Part 2 Class B of the General Permitted Development Order grants permission for it, but only where the access serves a highway that is not a trunk road or a classified road, and only where the access is required in connection with development that is itself permitted.

The practical translation is short.

Authorities publish their classified road network, and the classification is not always what the road looks like. A quiet residential street can be a C road. Check before assuming.

Permitted development rights can also be removed by an Article 4 direction, and they are restricted for listed buildings and within their curtilage. A conservation area does not by itself remove the access right, although it changes what the authority will accept in design terms. The only formal way to confirm that works are lawful is a lawful development certificate, and on a boundary case it is worth the fee.

Front garden surfacing and the drainage rule

The crossing is only half the job. The hardstanding behind it is separate development, permitted under Part 1 Class F as a hard surface incidental to the enjoyment of the dwellinghouse, with one condition that catches almost everyone.

Where the new surface between the house and the highway exceeds five square metres, it must be made of porous material, or it must be laid so that surface water runs to a permeable area within the curtilage. Otherwise planning permission is required. A block-paved drive draining onto the footway is the classic breach, and it is visible from the street.

Permeable block paving, gravel over a permeable sub-base, or a conventional surface falling to a soakaway or a planted strip all comply. On a small plot where infiltration is poor, the reasoning behind a Drainage Strategy applies in miniature: work down the hierarchy and record why the chosen method was chosen.

What the highway authority checks

The technical assessment is about whether a driver can enter and leave safely, and it is unforgiving because the authority carries the safety liability.

• Visibility in both directions along the footway and the carriageway, measured from a set-back point behind the boundary. The distances required rise with traffic speed, and the authority will use the recorded speed rather than the posted limit where the two differ.
• Space to park clear of the footway. A depth of about five metres between the back of footway and any garage door or wall is a common minimum, because a car overhanging the footway defeats the purpose.
• Gradient, so that a vehicle does not ground on the kerb line or run water back onto the highway.
• Width, usually a stated minimum at the kerb line with splayed edges.
• Proximity to a junction, a pedestrian crossing, a bus stop or a traffic island, any of which can rule out the position entirely.

None of this is negotiable by argument. Where the frontage fails on visibility, the answer is a different position or a redesigned boundary treatment, and a low front wall rebuilt at 600 millimetres often solves it.

Trees, utilities and parking bays

Three things routinely stop an otherwise straightforward application.

A street tree in the crossing line will not normally be removed, and the authority will offer a position to one side or refuse. Where a tree in your own front garden is protected, a tree survey showing the root protection area is the first step, since excavation for the hardstanding can be more damaging than the crossing itself.

Utility apparatus under the footway, particularly a gas governor, a fire hydrant, a chamber cover or a lighting column, may need diverting at the applicant's cost, which can exceed the cost of the crossing several times over. Ask the authority to identify apparatus at the inspection stage.

In a controlled parking zone, removing a residents' bay to make room for the crossing requires a change to the traffic regulation order, with its own advertisement and objection period. That process runs in months rather than weeks and is often the reason a crossing takes a year.

Cost and who carries out the work

Highway authorities publish their charges, and the figure depends on the crossing width, the footway construction, whether the verge is grassed and whether any apparatus needs adjusting. Treat any number you find online for another area as indicative and take the current published schedule from your own authority.

Budget separately for the hardstanding, any boundary wall alterations, and drainage. Where planning permission is needed, a short Planning Statement addressing highway safety and the character of the frontage is worth including, because these applications are often refused on the appearance of the frontage rather than on the access itself.

The order to do it in

1. Identify the road classification and check for an Article 4 direction or a listing.
2. Ask the highway authority informally whether the frontage can achieve the visibility and set-back standards, before spending anything.
3. Apply for planning permission if the road is classified, or for a lawful development certificate if you want the permitted development position confirmed.
4. Apply under section 184 once the planning position is settled.
5. Book the works, and arrange the hardstanding and drainage to be completed at the same time.

Doing steps three and four in the other order is the usual mistake. A section 184 consent for a crossing that planning then refuses is money spent twice.
