Getting Free Driveway Quotes: Red Flags of Cowboy Contractors

Updated 14/09/2026 · 4 min read

Driveway work has one of the UK's worst reputations for cowboy contractors and doorstep cold-calling - "we've got leftover tarmac from a job down the road" is one of the most well-known scam openers in home improvement. Knowing what a fair quoting process looks like is the best protection.

What a fair quote process looks like

• An in-person site visit before a firm price, not a number given over the phone with no assessment of ground conditions at all
• A written, itemised quote breaking down excavation, sub-base, surfacing and any drainage or kerbing work separately
• No pressure to sign or pay a deposit on the spot
• A clear timeline and start date, not a vague "we'll fit you in this week"
• Willingness to answer questions about sub-base depth, materials, and their own insurance without hesitation

Classic red flags

• "Leftover materials from a job nearby" - a genuinely famous cold-call tactic, almost never a real coincidence, and often a sign of substandard materials or no proper sub-base at all
• Pressure to decide immediately, often with a "today only" discount that doesn't stand up to scrutiny
• Cash-only, no invoice - makes it much harder to pursue a complaint later if the driveway fails within months
• A quote dramatically below others with no clear explanation - almost always means a thinner sub-base or fewer excavation hours than the job actually needs
• Reluctance to provide insurance details or a written guarantee
• Requesting full or majority payment before work starts - a modest deposit is normal, being asked for most of the cost upfront is a real risk

What to do if you suspect a problem after the fact

If a driveway has already started cracking, sinking or pooling water within a year or two of being laid, get a second, independent opinion from a different contractor before raising a dispute - a written assessment identifying the actual cause (usually inadequate sub-base or poor drainage) is far more useful than a general sense that something's wrong.

Comparing quotes properly

Getting 2-3 quotes is the single most effective protection against both being overcharged and ending up with a driveway that fails early - it gives you a genuine baseline to judge any individual quote against.
