Tarmac vs Gravel vs Resin Driveways

Choosing a driveway surface is one of those decisions that looks straightforward until you start comparing quotes. Tarmac, gravel, and resin are the three surfaces most UK homeowners consider after block paving, and each makes a compelling case depending on your budget, aesthetic preference, and how much maintenance you’re prepared to do.

This guide sets out honest 2026 costs, practical performance differences, and the planning rules you need to know before work starts.

At a Glance: Cost and Key Facts

Note: resin-bound (aggregate mixed into resin before laying) and resin-bonded (aggregate scattered onto wet resin) are different products. Resin-bound is permeable and far more durable; resin-bonded is cheaper but not SuDS-compliant and sheds aggregate over time.

Gravel Driveways

What it is

Loose gravel (typically 10–20 mm angular stone or pea gravel) spread over a compacted sub-base and held in place by plastic or timber edging. Depth is usually 50–75 mm for a functional driveway.

Costs

• Gravel supply and delivery (per tonne): £50–£90 depending on stone type and distance
• Installation, from gravel laid on firm compacted ground to a new 150 mm hardcore sub-base: £10–£30/m²² (2024 price, brought to 2026)
• Plastic grid systems (to hold gravel in place): add £5–£10/m²

A 40 m² driveway in plain gravel might cost £400–£1,200 installed, by far the cheapest of the three options.

Pros and cons

Gravel is permeable by nature, so it’s automatically compliant with the 2008 planning rules around surface water run-off.³ It deters intruders (the crunch of footsteps is hard to muffle), and it’s easy to install yourself if you’re comfortable with a barrow and a rake.

The downsides are real though. Loose gravel migrates, into flowerbeds, onto lawns, and across the pavement, unless you use a grid system or good edging. It needs topping up every few years. Leaves and debris are difficult to sweep, and in autumn it can become a chore to keep clear. Wheelchairs and pushchairs manage poorly on loose surfaces.

Tarmac Driveways

What it is

Tarmac (properly called asphalt) is a bitumen-bound aggregate laid hot and compacted by roller. Residential driveways typically use a binder course of 40–50 mm topped with a 20–25 mm wearing course, so around 65–75 mm total depth over a well-prepared sub-base.

Costs

• Standard black tarmac (supply and lay): £45–£65/m²
• Coloured tarmac (red, buff, green): £55–£75/m²
• Sub-base, excavation, and disposal (if needed): £15–£30/m²

Worked example, 50 m² tarmac driveway:

• Sub-base and preparation: 50 × £22 = £1,100
• Tarmac (binder + wearing course): 50 × £55 = £2,750
• Edging and kerbs: 30 m × £30 = £900
• Total (approximate): £4,750

Pros and cons

Tarmac is quick to lay, a typical residential driveway can often be done in a day, and ready to use within 24–48 hours. It’s durable, handles freeze-thaw cycles well, and is straightforward to repair (patches bond well to existing tarmac). Maintenance is minimal: a light seal coat every 5–7 years extends life significantly.

The main limitation is drainage. Standard tarmac is impermeable, which means surface water must drain somewhere. This either requires a gradient to a soakaway or lawn, or a drainage channel connecting to a drain. In a front garden, though, an area over 5 m² must be laid to shed water onto a lawn, border or other permeable area within the property, or it needs planning permission.⁴

Aesthetically, tarmac is plain black (or a limited range of colours). It won’t match a heritage property or a garden landscaped with natural stone. It can soften in prolonged high temperatures, a rare but real issue in very sunny, sheltered spots.

Resin-Bound Driveways

What it is

Resin-bound surfacing mixes natural aggregate (marble, granite, quartz, or recycled glass) with a UV-stable polyurethane resin before laying. The resulting surface is porous, water drains through the voids in the aggregate, and the aggregate is fully bound so it doesn’t shed underfoot.

It’s typically laid at 15–18 mm thickness over a tarmac or concrete base (or onto a suitable existing surface); the finished surface is only permeable if that base is, so a driveway meant to drain through needs a porous asphalt or similar permeable base. It can be installed in almost any colour or aggregate combination.

Costs

• Resin-bound surface (supply and lay, onto a suitable existing base): typically £60–£120/m²
• New sub-base and base layer, where the existing surface is unsuitable: £30–£50/m² extra

Resin-bonded (the cheaper, non-permeable variant) costs £40–£65/m² installed but is not recommended where drainage compliance matters.

Pros and cons

Resin-bound is the premium option for a reason: laid on a permeable base it lets water drain through, so a front driveway of any size needs no planning permission for its surface, and it is extremely low maintenance, doesn’t harbour weeds, and looks distinctive.³ The colour and aggregate palette is wide, and the smooth surface suits wheelchairs and pushchairs well.

UV-stable resin is critical, cheaper resins yellow within a year or two in UK light. Always ask for a UV-stable (aliphatic) resin and check the supplier’s guarantee. On north-facing, permanently shaded areas moss can colonise the surface; an annual treatment keeps this in check.

The base preparation is critical. Resin-bound will crack if the substrate moves, so it can’t be laid over an unstable or poorly draining base. Repairs are visible, as colour-matching a patch exactly is very difficult.

Planning Permission: What You Need to Know

Since 1 October 2008, a new or replacement hard surface of more than 5 m² between the front of a house in England and the road has needed planning permission unless it is permeable or drains to a permeable area within the property.⁵ Wales, Scotland and Northern Ireland have their own rules.

The practical upshot:

• Gravel: permeable, so no permission needed.
• Tarmac: standard tarmac is not permeable, so a front-garden area over 5 m² needs permission unless its run-off is directed to a lawn, border or other permeable area within the property; porous asphalt avoids this.³
• Resin-bound: permeable when laid on a permeable base, so no permission needed (resin-bonded is NOT permeable).

Always check with your local planning authority before proceeding, especially in a conservation area or an Article 4 direction zone where permitted development rights may be reduced.⁶

Which Surface Should You Choose?

No surface is perfect. Gravel is cheap but requires management. Tarmac is practical but plain. Resin is beautiful but expensive and unforgiving of a poor base. The best choice is the one that fits your budget, your property’s character, and how much time you want to spend maintaining it.

Finding a Reliable Contractor

Get at least three written quotes, specifying the same specification in each so you’re comparing like for like. For tarmac, look for a firm registered with TrustMark, the government-endorsed quality scheme for work in and around the home.⁷ Resin-bound specialists should be trained and approved by their resin manufacturer. Be cautious of cold-call firms offering cash-in-hand deals with tarmac, this is a common sector for rogue traders.

Always ask to see examples of previous work and request references from recent customers before you sign.
