How to Vet a Driveway Contractor: The Checks That Actually Matter

Updated 14/09/2026 · 4 min read

Driveway work is one of the most common categories for doorstep cold-calling and rushed, poor-quality jobs in the UK - partly because a badly built driveway can look fine for the first year before sub-base problems show up. A few concrete checks separate a competent contractor from a risky one.

Companies House registration

A registered limited company has a filing history you can actually check - incorporation date, filed accounts, registered address. This doesn't guarantee quality, but a business that's been trading and filing accounts for several years is a materially different risk than one with no verifiable history at all.

Insurance

Ask specifically for proof of public liability insurance, covering damage to your property or a neighbour's during excavation and laying work, and ideally employer's liability if they have staff. A legitimate contractor will produce this without hesitation.

Trade body membership

Membership of a recognised trade association for paving and driveway contractors isn't compulsory, but it's a useful additional signal - it usually means a level of vetting and access to a complaints or arbitration process that an unaffiliated trader doesn't offer.

Guarantees, in writing

A written guarantee on both materials and workmanship - not just a verbal assurance - should specify what's covered and for how long. Sub-base failure and drainage issues are the most common driveway defects, so check specifically that the guarantee covers these, not just surface staining or discolouration.

How they describe the sub-base

Ask any contractor quoting to explain their proposed sub-base depth and material, and why. A contractor who can't or won't discuss this in any detail, or who seems to be quoting a standard depth regardless of your specific ground conditions (see our guide to clay ground), is a real warning sign - sub-base corner-cutting is the single most common reason driveways fail early.

References and reviews on an independent platform

Reviews on a platform the contractor doesn't control are harder to fake and easier to verify than testimonials on their own website. Photos of completed work, ideally a few years old so you can see how it's held up, are worth asking for directly.

A simple pre-work checklist

• Company registered and trading history checkable
• Public liability insurance confirmed, ideally seen not just claimed
• Written guarantee covering sub-base and drainage, not just the surface
• Clear explanation of sub-base depth and drainage approach for your specific property
• Independent reviews, not just testimonials on their own site
