Summary

Gravel is the cheapest driveway surface to install and one of the easiest to get wrong. The material itself is inexpensive — the job is priced on groundworks, edge restraints and the sub-base that stops the whole thing migrating into the road or sinking into the ground within a couple of winters. A lot of gravel driveway complaints and comebacks trace back to skipping or underspecifying one of those three things to hit a cheap headline price, not to the gravel itself.

This guide covers pricing a gravel driveway from both ends: a straightforward "top up an existing compacted base" resurfacing job, and a full new-build driveway with excavation, sub-base, geotextile membrane and edge restraints. The two scenarios have very different cost profiles, and being clear with the customer about which one they're actually asking for avoids the classic mismatch between a cheap per-m² figure they've seen quoted online and the real cost of a durable new driveway.

For the wider material comparison against block paving, resin bound and tarmac, see driveway types. This guide focuses specifically on the pricing detail for gravel.

Driveway size Resurface/top-up over existing base Full new installation (excavation + sub-base)
20m² (small, off-street parking) £500–£1,100 £1,200–£2,200
35m² (average 3-bed semi) £900–£1,900 £2,100–£3,900
50m² (larger semi/detached) £1,300–£2,700 £3,000–£5,500
70m² (large detached) £1,750–£3,850 £4,200–£7,700
100m² (long driveway/multiple vehicles) £2,500–£5,500 £6,000–£11,000

Detailed Guidance

Why "£20–40/m²" and "£3,000 for a 35m² driveway" Are Both Correct

Supply-and-lay-only rates commonly quoted for gravel (roughly £20–50/m²) assume an existing, adequately compacted sub-base is already in place — a resurfacing job. Add the excavation, a proper MOT Type 1 sub-base, geotextile membrane and edge restraints needed for a genuinely new driveway, and the realistic all-in cost is closer to £60–110/m². Both figures are accurate; they're pricing different scopes. Establish which one the customer actually needs at the survey stage — most people asking for "a gravel driveway" on a patch of lawn or an old, failed surface are asking for the full new-build scope, whether they realise it or not.

Price Drivers

Self-Binding Gravel vs Loose Decorative Gravel

Self-binding gravel (crushed limestone, granite or sandstone dust with a graded particle mix) compacts into a firm, relatively stable surface when rolled — closer in feel to a hoggin path than loose stones. It's a popular choice where a neater, less "crunchy underfoot" finish is wanted, and it migrates less than loose gravel. It still needs periodic maintenance (occasional re-rolling, topping up worn areas) but holds its surface for longer between full top-ups than loose gravel.

Loose decorative gravel (20mm shingle, slate chips, pea gravel) is the cheaper, more common choice, particularly for driveways where aesthetics matter as much as function. It drains excellently and is genuinely maintenance-free in the sense that it never needs resurfacing — but it migrates over time (onto pavements, into the sub-base if there's no membrane, kicked out by tyres at the entrance), and most driveways need a top-up delivery every 5–10 years.

Sub-Base and Membrane — Not Optional Extras

A gravel driveway without a proper sub-base will rut, pond and sink under vehicle weight within a season or two, regardless of how good the gravel itself is. The construction, bottom to top:

  1. Excavate to accommodate the full build-up (sub-base + membrane + gravel depth), typically 150–250mm total depending on ground conditions
  2. Compact the sub-grade (the exposed ground) before adding anything
  3. MOT Type 1 sub-base, minimum 100mm compacted (150mm on clay or for frequent heavy vehicle use), laid in layers and compacted with a vibrating plate or roller
  4. Geotextile membrane over the compacted sub-base — this is the layer most often skipped to save cost, and its absence is the single biggest cause of gravel disappearing into the sub-base and weeds coming through
  5. Gravel dressing, 40–75mm depth, raked level and to the required fall

Skipping the membrane to save £70–£140 on a typical driveway is a false economy that shows up as a comeback complaint within a year.

SuDS and Drainage Compliance

Because gravel is inherently permeable, it does not trigger the planning permission requirement that applies to impermeable front-garden surfaces over 5m² under the GPDO rules (see driveway types and permeable paving). This is a genuine selling point against tarmac, concrete or standard block paving for customers who want to avoid a planning application — worth mentioning explicitly when quoting against those alternatives. It's also consistent with SuDS (Sustainable Drainage Systems) principles under current NPPF guidance, which favour infiltration over piped surface water disposal (see suds regulations driveways for the fuller compliance picture across driveway surface types).

Worked Example: 35m² New-Build Gravel Driveway

Property: 3-bed semi, existing front garden lawn being converted, standard access for a tipper lorry, moderately draining subsoil.

Item Cost
Excavation to reduce level (35m² × 150mm) + muck-away £650
MOT Type 1 sub-base, 100mm compacted (~7.5 tonnes) £280
Geotextile membrane, 35m² £90
Timber edge restraint (approx. 24m perimeter) £400
Self-binding gravel dressing, 40mm depth (~2.6 tonnes) £180
Labour (groundworker, 2.5 days) £650
Plant hire (mini digger + wacker plate, 1 day) £220
Margin (22%) £540
Total £3,010 (~£86/m²)

A driveway with easier access, no fall correction needed, and loose gravel instead of self-binding could come in nearer £2,400–£2,700 for the same size. A driveway on clay requiring a deeper sub-base, or with poor tipper access needing wheelbarrow runs, could run £3,800–£4,500.

Common Pricing Mistakes

Frequently Asked Questions

How much gravel do I need for my driveway?

Work from the coverage rate: roughly 13–14m² per tonne at a 50mm depth, or about 9m² per tonne at 75mm. Multiply the driveway area by the desired depth in metres, then divide by roughly 0.67 (the volume in m³ that one tonne of gravel occupies) to get the tonnage required. Always round up and order slightly more than the calculation suggests — running short mid-delivery is more expensive than having a small surplus.

Do I need planning permission for a gravel driveway?

No. Gravel is a permeable surface, and permeable driveway surfaces are permitted development regardless of area under the current front-garden rules. This applies whether it's a small parking bay or a large multi-vehicle driveway. Impermeable surfaces (tarmac, concrete, solid block paving) over 5m² are the ones that trigger the planning requirement — see driveway types for the full comparison.

How often will I need to top up the gravel?

Loose decorative gravel typically needs a top-up delivery every 5–10 years, depending on traffic, whether it's raked/maintained, and how exposed the entrance is to migration (tyres kicking stones out at the transition to the road, for example). Self-binding gravel holds its compacted surface for longer between full top-ups but may need occasional patch-repair and re-rolling in high-wear areas like turning circles.

Can I lay gravel directly onto an existing lawn or soil?

Not for a durable driveway. Gravel laid directly onto soil or turf without excavation, a compacted sub-base and a membrane will sink, rut and get contaminated with mud and weeds very quickly under vehicle weight. This might be acceptable for a decorative garden path with no vehicle traffic, but not for a driveway.
