How to Price a Dropped Kerb: Highway Authority Fees, Groundworks and Reinstatement

Quick Answer: A dropped kerb (vehicle crossover) installation in the UK costs £900–£2,800 typical for a single-width crossover, comprising local authority highway licence application (£100–£500), highway authority works fee (£600–£1,800), and the contractor's groundworks (£600–£1,800 for a typical 4–6m wide crossover). Only contractors approved by the local highway authority can carry out the works on the public highway — DIY or unapproved contractors cannot legally lower the kerb. Some councils carry out the works themselves; others approve specialist contractors for the work.

Summary

A dropped kerb is one of the few jobs that involves both private property contractor and a local authority highways permit at the same time, which makes pricing variable across UK councils and confusing for customers. The customer-facing cost typically splits into three distinct payments — the planning/licence application fee to the council, the works fee for the highway portion (paid to the council or to a council-approved contractor), and the private-side works on the customer's property (driveway construction, threshold drainage). Understanding each component lets the contractor quote accurately and avoids the customer feeling like extra costs are being added.

This guide covers the typical UK cost ranges for each component, the planning permission requirement (depending on whether the property fronts a classified road), the highway authority approval process, and the technical specification for the dropped kerb construction itself (concrete sub-base, kerb stones, surface reinstatement). It includes worked examples for single-width and double-width crossovers, and the cases where a "no" from the highway authority can be appealed or alternative routes (private vehicle access) considered.

The pricing trap most customers don't realise: planning permission and highway licensing are separate processes with separate fees. Planning permission is needed if the property fronts a classified road (A or B road); highway authority works permit is always needed regardless. A typical pricing miscommunication: contractor quotes the works fee but excludes the planning application — customer is then surprised by a £200–£400 unrelated council fee from the planning department weeks later. Better practice: itemise all fees on the quote with clear "this is collected by the council, not by us" labelling.

Key Facts

• Highway works permit — required from local authority for any work on the public highway; £100–£500 typical application fee
• Highway works fee — for the highway portion of the works (lowering the kerb, modifying the footpath); £600–£1,800 typical
• Planning permission — required if property fronts a classified road (A or B road) or if access is over a verge; £258 fee in England (2026)
• Highway authority — typically the County Council in non-unitary areas, the District/Borough/Unitary in unitary areas
• Approved contractor list — most highway authorities maintain a list of approved contractors for crossover works; using non-approved contractors is unlawful
• Council-undertaken works — some councils do the highway works themselves rather than approve contractors; cost typically similar
• Section 184 Highways Act 1980 — primary legislation for vehicle crossings
• Crossover width — typically 3.6–4.5m for single-width, 5.5–7.0m for double-width
• Dropped kerb height — flush at base, rising to typically 25mm above carriageway at edges
• Private side construction — driveway sub-base + surface to design (block paving, concrete, tarmac, gravel)
• Drainage requirement — surface water from drive cannot discharge onto highway (Highway Act 1980); requires soakaway, attenuation, or surface water sewer
• Permeable paving exemption — fully permeable paving may not require separate drainage if infiltration is adequate
• Highway closure or traffic management — required during the works; usually included in highway works fee
• Footpath reinstatement — flagstone or paviour to match existing; included in highway works
• Statutory utilities check — services in the highway must be located and protected (LinesearchBeforeUDig, free)

Detailed Guidance

When you need a dropped kerb

A dropped kerb (also called vehicle crossover, VXO, or vehicular crossing) is required wherever a vehicle is intended to cross the public footpath to access a private driveway. Driving over a non-dropped kerb is:

• Damaging to the kerb stones and footpath
• Unlawful under Highway Act 1980 (potential £1,000 fine)
• Often spotted by neighbours or council officers
• A frequent cause of disputes and enforcement notices

If your customer is paving a driveway and there isn't already a dropped kerb at the access point, the dropped kerb must be done as part of the project — or the customer cannot legally drive over the new driveway.

The application process

Process varies slightly by council but typically:

1. Initial enquiry — customer or contractor contacts council Highways department
2. Planning permission check — does the property front a classified road? If yes, planning consent required first (£258 fee, 8-week determination period)
3. Highway licence application — formal application with site plans showing crossover width, threshold detail, drainage proposal
4. Site survey by council officer — typically 2–4 weeks after application; checks visibility splays, road safety, sight lines for vehicles emerging
5. Approval or refusal — if approved, the council issues either a quote for council-delivered works or directs the customer to use an approved contractor list
6. Works carried out — typically 1–2 days for a standard single-width crossover including footpath reinstatement
7. Inspection and sign-off — council inspector verifies completed works meet specification

Total elapsed time: typically 8–16 weeks from initial enquiry to completion.

Reasons for refusal

A highway authority can refuse a dropped kerb application for:

• Inadequate visibility splay — sight lines too short for safe vehicle emergence (usually 2.4m × 33–43m measurement)
• Highway tree or street furniture — a lamp column, bus stop, or mature street tree at the access point
• Adjacent junction — too close to a road junction (typically <10m)
• Bus route or red route — Transport for London or council restrictions on certain roads
• Service apparatus — unmoveable utility chambers or cables
• Conservation Area — local planning officer objections
• Insufficient on-property turning space — if driver would need to reverse onto highway

Refusals can be appealed via the council's Highways committee or, in some cases, via the Planning Inspectorate (where planning permission was refused).

Highway works specification

The technical specification for the dropped kerb portion is council-specified, broadly following:

Council inspectors check specifically:

• Kerb line aligns with adjacent kerbs (no waves or steps)
• Threshold height correct (vehicles can mount without scraping or air-bouncing)
• Footpath finished level matches surrounding (no trip hazards)
• Highway gully connections preserved
• Visibility splay clear of obstruction

Private-side construction

The driveway from the dropped kerb threshold to the customer's property is the customer's responsibility and the contractor's main scope of work. Typically:

A typical 4×8m driveway = 32m². Using premium block paving = £3,200–£4,800 supply and fit, plus dropped kerb works £900–£2,800.

Drainage — the often-missed compliance issue

Surface water from the new driveway must NOT discharge onto the highway. Highway Act 1980 makes this unlawful — and councils enforce. Three compliant options:

1. Soakaway: in front garden, sized per BRE Digest 365; typical cost £1,000–£2,500
2. Linear drainage channel + soakaway: channel at threshold, soakaway behind; £1,800–£3,500
3. Permeable paving: porous surface allows water to drain through paving into sub-base; no separate channel needed; £100–£170/m² fitted

For most domestic drives in clay soil (low infiltration), permeable paving is the easiest compliance route — the build-up has a deeper aggregate sub-base that stores and slowly releases water without needing a soakaway.

For the homeowner — practical advice

Three things to do early:

1. Check road classification — call the council or look up online. If your road is "A" or "B" classified, you need planning permission first
2. Check the visibility splay — stand at the proposed access point and check what you can see in each direction at 2.4m back from the kerb. Inadequate visibility = automatic refusal
3. Talk to neighbours — neighbour objections rarely block a dropped kerb but a co-operative neighbour relationship matters

Don't pay any contractor in full upfront for crossover works — councils have been known to refuse approval after work commenced, leaving customer with non-compliant access. Pay a deposit, milestone payment after council approval, balance on completion.

Ask the contractor to show evidence of being on the council's approved list — contractors not on the list cannot legally do the highway portion.

Frequently Asked Questions

Can I do the dropped kerb work myself?

No. Work on the public highway requires either the council to do it or a contractor approved by the council. DIY work on the highway is unlawful under Highway Act 1980 and can result in the work being removed at your cost (£1,500–£3,000) plus fines. The private-side driveway work can be done by any competent contractor (or DIY); only the highway portion is restricted.

How long does the application process take?

8–16 weeks typically from initial enquiry to completion. Planning permission (if needed) adds 8 weeks. Some councils are faster; some are slower (especially London boroughs and counties with high application volume). Build the timeline into your project programme — don't book paving works until you have the highway permit in hand.

Why are highway works so expensive compared to private-side work?

Several reasons: traffic management costs (cones, signage, sometimes traffic light hire); footpath reinstatement to council specification; statutory utilities checks and protection; council inspection fees; the council's own administrative overhead; and the limited approved-contractor competition that pushes prices up. The £1,000+ for a 4m kerb feels high until you see the kit involved — most jobs require excavator, traffic management, kerb breakers, mini roller, and a 2-3 person crew for a day.

Can I appeal a refusal?

Yes. First step is informal discussion with the council Highways officer — sometimes refusals are based on misunderstandings or fixable issues. Formal appeal goes to the council's Highways committee or, where planning permission was the issue, the Planning Inspectorate (£0 fee for householder appeals). Success rates are moderate — visibility splay refusals are particularly hard to appeal.

Do I need a dropped kerb to park on my own driveway?

Yes — driving over a non-dropped kerb to access your driveway is unlawful even if the driveway itself is legal. Many older properties have parking spaces with no formal dropped kerb because the access pre-dates current regulations or the kerb was never properly lowered. Resolving this often requires retrospective dropped kerb application and works.
