The short answer
Laying a new tarmac driveway in the UK typically costs around £45–£80 per square metre installed, depending on size, ground conditions and access. By size that usually works out at roughly £2,500–£4,000 for a standard 50m² drive, with smaller single-car drives often a little higher per square metre and large drives a little lower. Overlaying a sound existing tarmac surface is lower in cost, commonly around £40–£55 per square metre, because there is far less excavation and sub-base work. The figure mainly moves with the area, how much digging out and sub-base is needed, the edging, and any drainage the SUDS rules require.
Price depends mostly on the area, how much excavation and sub-base the ground needs, and access for machinery and deliveries. The figures below are typical installed prices for guidance, not quotations.
Typical UK costs

- Standard 50m² drive~£2,500–£4,000
- Overlay (sound base)~£40–£55 / m²
- Resealing~£200–£400 every 3–5 yrs

What drives the price
- Area: you pay largely per square metre, so a larger drive costs more overall — though the rate per m² often eases slightly on bigger jobs.
- Excavation & sub-base: digging out and laying a proper compacted Type 1 sub-base is much of the cost; soft or sloping ground adds to it.
- Edging & drainage: a concrete or block edge restraint, plus any soakaway or channel drain needed for SUDS, add to the figure.
- Access: tight access or long barrow runs for tarmac and spoil add labour and time.

|---|---|---|
| New tarmac installed | £45–£80 / m² | varies by size, ground & access |
| Standard 50m² drive | ~£2,500–£4,000 | before extra drainage / excavation |
| Overlay on sound base | ~£40–£55 / m² | much less sub-base work |
| Resealing | ~£200–£400 | every 3–5 years, whole drive |

Why the lowest-priced quote often isn't the lowest in cost
Most of a tarmac job is hidden in the ground: the excavation, the compacted 100–150mm Type 1 sub-base and the edge restraint. A quote that comes in well under the others has usually skimped on exactly those things — a thinner base or no proper edging — which is why the surface ripples, sinks or ravels within a few years. Across the life of the drive, the build that's done properly often works out lower in cost than the one that's relaid early. Compare quotes on the same scope: sub-base depth, edging, drainage and waste removal all written down.

Frequently asked questions
How much does a tarmac driveway cost in the UK?
Typically around £45–£80 per square metre installed, which works out at roughly £2,500–£4,000 for a standard 50m² driveway. Smaller drives often cost a little more per square metre and larger drives a little less; extra excavation, drainage and edging move the figure.
Is it lower in cost to overlay an existing tarmac driveway?
Usually yes, where the existing surface and base are still sound. An overlay is commonly around £40–£55 per square metre because there is far less excavation and sub-base work — but it only works if what's underneath is structurally sound.
Why is the price range so wide?
Because driveways differ. The area, how much excavation and sub-base the ground needs, the edging and any drainage all move the figure. A measured quote gives the accurate number for your drive.
