How Much Does a Tarmac Driveway Cost?

Typical Costs (2026 UK Prices)

• Small driveway (30m²): £1,200–2,100
• Medium driveway (50m²): £2,000–3,500
• Large driveway (80m²): £3,200–5,600

Prices include excavation, sub-base preparation, and two-coat tarmac application.

How Tarmac Depth Works

A typical domestic tarmac driveway has two layers:

• Base course (binder): 40–50mm of 20mm open-graded asphalt
• Surface course (wearing): 20–25mm of 6mm dense asphalt
• Total depth: 60–75mm

Sub-base Requirements

Before tarmac is laid, the ground needs a compacted sub-base of 100–150mm MOT Type 1 aggregate. Poor sub-base preparation is the main cause of tarmac driveways cracking and sinking.

Factors Affecting Cost

• Access: Tight access or long carry distances add cost
• Drainage: May need new drainage channels or soakaways
• Edging: Block or kerb edging adds £15–30/linear metre
• Removal of old surface: £10–20/m² extra
• Coloured tarmac: 20–40% premium over standard black

• Block paving: £60–120/m²
• Gravel: £20–40/m²
