Driveway Cost Estimator

How Estimates Work

Costs reflect 2025 UK averages for materials and labour. Enter your driveway size in square metres, select a surface type, and add extras like equipment hire. Figures draw from professional surveyor data across regions.

Material Breakdown

• Tarmac suits slopes and heavy use, lasting 10-20 years with proper base.
• Block paving offers patterns but needs sharp sand bedding for stability.
• Resin bound drains water naturally, meeting SUDS rules without channels.
• Concrete imprints mimic stone at lower cost, prone to cracks if base shifts.
• Gravel provides drainage and security noise, requires edging to contain stones.

Size Guide

Single car: 20m². Double car: 50m². Multiple cars: 100m²+. Measure length times width; break irregular shapes into rectangles and sum areas.

Ground Preparation

Dig 150mm below damp proof course, add 150mm Type 1 hardcore sub-base, compact firmly. Edge with kerbs to hold structure. Slope 1:80 away from house or fit soakaways.

SUDS Rules

Permeable surfaces like gravel or resin avoid planning needs under 5m². Impermeable types require drainage to prevent runoff.

Common Queries

• Does resurfacing save money? Yes, £50/m² versus full replacement at £90+/m² for tarmac.
• Why varies by region? Labour £30-£50/m² higher in London, materials steady nationwide.
• Extension costs? £100-£250/m² to overlay matching current surface seamlessly.
• Gravel maintenance? Rake yearly, add membrane against weeds.
• Seal block paving? Yes, locks sand and stains, applied post-compaction.

Material Comparison

Finding Contractors

• Seek RICS or CIOB members for quotes.
• Check insurance and 5+ year guarantees.
• View aged installs, not just new ones.
• Get three detailed quotes, avoid unreal lows.
