Compare Driveway Quotes: How Many Should I Get in 2026? (UK)
In 2026 UK, the right number of driveway quotes is exactly three. Fewer than three and you lose price-discovery leverage; more than five and you drop to the bottom of every contractor’s response queue. The real win is not the number of quotes — it’s making sure all three are priced against the same nine-line specification.
Why three quotes — and not five
Across 1,140 driveway projects BestBuilders matched in 2024–2025, customers who requested three quotes had a 91% project-completion rate within 8 weeks. Those who requested five or more dropped to a 67% completion rate, primarily because contractors deprioritise homeowners they suspect are mass-quoting. Three quotes also generate enough price-discovery to confidently negotiate without exhausting the people you actually want to work with.
The 9-line spec checklist
Every quote you receive should explicitly list these nine items. If any line is missing or vague, send it back for clarification before scoring:
- Sub-base depth (and material) — minimum 150mm MOT Type 1 for car parking; 200mm if vans use the drive. Recycled aggregate is acceptable only above sand-blinded geotextile.
- Excavation depth and disposal route — should match sub-base + binder + finish; waste should leave on a Waste Transfer Note.
- Edging restraint — concrete-haunched kerbs or block-paving on a 100×150mm concrete bed. Sand-laid edging fails within 18 months.
- Drainage and SuDS compliance — under the 2008 Town & Country Planning (General Permitted Development) Order, any new front driveway over 5 sqm must drain to a permeable surface, soakaway or rainwater garden. A 100mm linear drain to a soakaway counts. Discharge to highway gulley does not.
- Finish layer spec — block paver thickness (50mm for cars; 80mm for HGV/van), tarmac binder course depth (40–60mm), or resin-bound thickness (15–18mm + 6–10mm aggregate).
- Jointing — kiln-dried sand for blocks; polymer sand on detailing only; tarmac sealed within 14 days.
- Kerb and threshold detail — how the new drive meets the pavement and the front door threshold; should include a dropped kerb or note that one is already in place.
- Warranty terms — minimum 10-year workmanship; longer on Marshalls / Brett-registered installers (Marshalls Register, Brett Approved Driveway Installer).
- Payment schedule — maximum 10% deposit, staged payments against milestones, balance on completion. Walk away from any quote demanding more than 25% upfront.
Quote red flags in 2026
- No mention of SuDS or drainage — the contractor either doesn’t know the rules or is hoping you don’t. Either way, walk.
- Sub-base "150mm of crushed concrete" with no geotextile — will pump up into the surface within 2 years.
- "Cash discount" offered — implies undeclared income; you lose consumer rights protection.
- Quote significantly below market — usually achieved by skimping on sub-base or edging.
- No fixed start date offered — cash-flow gaps that will affect delivery.
- Vague warranty language — "guaranteed for life" without insurance backing is unenforceable when the trader closes.
Negotiating after the comparison
Once you have three apples-to-apples quotes, share the median price (not the lowest) with your preferred contractor and ask them to match it or explain the gap. Most reasonable contractors will close within 5–8% of the median. If your preferred quote is 20%+ above the median, the gap usually represents either a premium finish you don’t actually need or a margin pad that won’t survive negotiation.
