Use the gravel driveway calculator to estimate a realistic UK budget for a new loose-stone driveway or a refresh of an existing gravel surface. A standard professionally built gravel driveway commonly falls around £40–£70 per m² in 2026, while projects needing deeper excavation, stronger base construction, premium aggregate or difficult access can move towards £60–£100 per m².
Estimate the likely cost of a new gravel driveway or an existing gravel refresh. The calculation considers stone choice, the surface already on site, access, location and common groundwork or finishing extras.

For a straightforward new driveway, a useful 2026 starting point is around £40–£70 per m² supplied and laid. That is not simply the price of the decorative stone. Most of the budget is usually tied up in excavation, a compacted sub-base, membrane, labour, delivery and edge restraint.
A driveway built on weak ground, one requiring large volumes of spoil to be removed, or one finished with more expensive granite, flint or decorative aggregate can cost considerably more. By contrast, refreshing an existing gravel drive with a sound base can be much cheaper because the expensive structural work may already be in place.
A gravel driveway performs properly because of the layers underneath it. The visible aggregate is normally a relatively shallow wearing course. Beneath it, a well-built driveway needs a stable, compacted base capable of carrying repeated vehicle loads without rutting or sinking.
On a full new build, contractors may excavate to roughly 150–200mm depending on the site, install a suitable geotextile membrane where required, compact a substantial Type 1 sub-base and then place the decorative gravel above it. Ground conditions, vehicle use and levels determine the final specification.
This is a groundwork job rather than a stone-delivery job. Excavation, spoil removal, level setting, sub-base installation and compaction normally make up the largest share of the cost. The calculator therefore uses a higher base allowance for a new driveway.
If the driveway already has firm edges and a sound compacted base, the work may only involve local levelling, repairing soft spots and adding fresh stone. Choose the refresh option only where the existing drive is already gravel and the underlying construction can genuinely be reused.
Angular stone is generally more suitable for vehicle areas than rounded pea gravel because the pieces lock together more effectively instead of rolling under tyres. Many driveway specifications use chippings in roughly the 14–20mm range, although the correct aggregate depends on the finish, drainage and supplier recommendations.
Standard angular gravel is usually the least expensive choice. Limestone gives a cleaner, more uniform appearance, while granite, flint and decorative aggregates typically carry a higher material cost. Colour alone should not decide the specification; durability, particle shape and local availability matter as well.
The estimate starts with driveway area, then applies separate allowances for the structural base, chosen aggregate, preparation of the existing surface, regional labour differences and access. Optional items are then added individually rather than being hidden inside one generic square-metre rate.
The most expensive surprises are normally below ground. Soft subsoil, tree roots, an old concrete slab, poor levels or an inadequate existing base can all add excavation and disposal work. Restricted access also matters because stone and sub-base may need to be moved by barrow or smaller machinery rather than tipped close to the work area.
Long perimeters can also make edging a significant cost. A loose gravel surface needs containment, particularly beside lawns, pavements and public roads. Stabilisation grids add to the initial price but can help reduce gravel movement on turning areas and sloping or heavily trafficked sections.
In England, Planning Portal guidance lists gravel as a permeable surface. A new or replacement front driveway using permeable surfacing can therefore normally be installed without planning permission on drainage grounds, regardless of area, provided water can drain through or be directed to a permeable area.
That does not remove every possible consent issue. Listed buildings, Article 4 Directions, planning conditions and other local restrictions can change the position. A new vehicle access across a pavement also requires an approved dropped kerb from the relevant highway authority.
Measure the site in metres and divide unusual shapes into simple rectangles. Work out the area of each section by multiplying length by width, then add the sections together. For a tapered drive, using an average width usually gives a reasonable budgeting measurement.
The calculator itself uses one length and one width, so for complex sites enter dimensions that produce approximately the same total square metres. A contractor will still need to measure levels, drainage falls and boundaries before giving a fixed quotation.
The result is a budget range, not a specification or contract price. It cannot inspect soil bearing strength, underground services, drainage outlets, retaining walls, contaminated material, unusual access restrictions or local aggregate availability. Those factors need an on-site assessment.
Use the estimate to compare project options and understand where the money is likely to go. Once the scope is clear, request itemised contractor quotes that state the excavation depth, sub-base specification, gravel type, edging, drainage and waste arrangements.
These figures are budgeting guides for typical UK domestic work in 2026. Site conditions and local material prices can move a quotation outside these ranges.
A standard professionally installed gravel driveway commonly costs around £40–£70 per m² in 2026. Projects with deeper excavation, restricted access, extensive edging or premium aggregate can move towards £60–£100 per m² or more.
The lowest-cost route is usually to reuse a sound existing sub-base and refresh the surface with suitable angular gravel. Starting from lawn or weak soil costs more because excavation, Type 1 sub-base, compaction and waste removal are required.
Depth depends on the ground and expected vehicle loading. A professional new build may use roughly 150mm of compacted sub-base beneath a shallower decorative gravel layer, although weak ground or heavier vehicles can require a different specification.
Angular, hard-wearing aggregate is usually preferred because it interlocks better under vehicle tyres. Limestone, granite, flint and other crushed stone can all be suitable when the grading and installation are appropriate.
Driveway chippings are commonly supplied in sizes around 14–20mm. Very small stone can migrate more easily, while very large aggregate can be uncomfortable to walk on. Follow the chosen aggregate supplier’s specification.
Rounded pea gravel is generally less stable than angular crushed stone because the particles roll rather than lock together. It can be used decoratively, but angular aggregate is usually the more practical choice for regular vehicle traffic.
A geotextile membrane is commonly used within a new driveway build to separate layers and help prevent the sub-base mixing with the soil below. The correct membrane position and specification depend on the ground conditions and construction design.
They can be useful where tyre movement, turning or gradients cause loose stone to migrate. Grids are not a substitute for a properly compacted base, but they can improve surface stability when specified and installed correctly.
Gravel is permeable, but the whole construction still needs to manage water safely. Compacted layers, surrounding ground, slopes and boundaries can affect runoff, so drainage channels or other measures may still be necessary on some sites.
In England, gravel is recognised as a permeable driveway surface and normally does not trigger the front-garden planning rule that applies to impermeable surfacing over 5m². Local restrictions, listed status or other planning controls can still apply.
Yes, if vehicles need to cross a public pavement to reach the property, an authorised dropped kerb is normally required. Applications are handled by the relevant local or highway authority and are separate from the driveway installation itself.
Yes, when the existing base remains firm, correctly shaped and well contained. Ruts, soft areas or drainage failures should be repaired before fresh stone is spread, otherwise the new gravel will only hide the underlying problem temporarily.
Sometimes, but the existing hard surface must be assessed first. Levels, drainage and edge containment are critical, and a smooth or damaged base may not provide a suitable long-term construction without additional preparation.
A small straightforward project may be completed within a few working days, while larger sites, poor ground, drainage work or extensive excavation can take longer. Contractor access and weather also affect the programme.
The quantity depends on surface area, finished gravel depth and the bulk density of the chosen aggregate. Suppliers normally convert the required volume into tonnes, so use the actual product specification rather than assuming one fixed weight per square metre.
Typical maintenance includes raking displaced stone back into place, topping up thin areas, controlling weeds and repairing ruts or soft spots. Edges should also be checked because loose aggregate can spread when restraints move or fail.
VAT is optional in the calculator. Select the VAT box to add the current standard UK rate of 20%. A contractor’s actual VAT treatment depends on whether the business is VAT registered and how its quotation is presented.
No. The calculator is designed for early budgeting. A fixed quotation requires an installer to assess levels, ground conditions, access, drainage, excavation, disposal, aggregate choice and the exact dimensions of the site.
