Why the installer matters more than the brochure
Almost every resin driveway failure traces back to one of four things: a sub-standard base, the wrong resin, poorly prepared aggregate, or a rogue trader who vanishes before snagging. Get the installer right and your driveway lasts 15–25 years; get it wrong and it can crack, yellow or pond within a couple of seasons. This is the decision that matters most.
Accreditations to look for
Because anyone can call themselves an installer, third-party vetting matters. Strongest are manufacturer-approved installers — SureSet, Addagrip Approved Contractors, or a Marshalls Registered Installer (the only route to the Marshalls guarantee, which stands even if the firm stops trading). Also look for national schemes: TrustMark (the Government-endorsed quality scheme), Buy With Confidence (vetted by Trading Standards), and BALI (British Association of Landscape Industries). Treat Checkatrade as a starting point only — its guarantee is capped well below the cost of a failed driveway. Re-check any badge on the scheme's own website.
Check their past work
Ask for three verifiable local references from the last 12–24 months and actually call them. Ask to see a completed driveway in person and look at colour uniformity, edges and drainage. Check the company on Companies House, verify any VAT number, and search the company name alongside “complaints”. Stolen website photos are a known trick, so insist on seeing real, named, local jobs.
Questions to ask before you hire
- What base preparation do you propose? Look for: excavate to a stated depth and lay a compacted MOT Type 3 sub-base with a membrane — not a thin layer over the old surface.
- What resin system, and is it UV-stable? Look for: a named brand using UV-stable (aliphatic) resin, with a data sheet.
- What wearing-course depth? Look for: around 18 mm for cars, more for heavy or turning areas.
- Is it permeable — do I need planning permission? Look for: a permeable build that is SUDS-compliant and usually needs no permission.
- What guarantees do you offer, and are they insurance-backed? Look for: a 10-year-plus written workmanship guarantee plus the manufacturer guarantee, ideally insurance-backed.
- Will you use a forced-action mixer and dried aggregate? Look for: yes — moisture and hand-mixing cause failures.
- Who carries out the work? Look for: a named, trained, supervised crew covered by the firm's insurance.
- How is waste handled? Look for: removed by the installer, with a waste-transfer note on request.
What a written quote must include
Decline anyone who will not put it in writing. A complete quote states the business name, address and company/VAT number; the area in m²; the excavation and base method (depth, sub-base, membrane, edging); drainage; the named resin system and aggregate; the wearing-course depth; waste removal; start date and duration; guarantee terms; the payment schedule; and the total price including VAT. Be wary of vague “quality resin”, a price far below everyone else, or no VAT shown.
Deposits and your consumer rights
A reasonable structure is a 10–20% deposit, the balance staged through the job, and a final payment on your sign-off. Never pay more than 25–30% upfront and avoid large cash deposits. Pay by credit card: under Section 75 of the Consumer Credit Act, paying even the deposit by card (on contracts between £100–£30,000) makes your card provider jointly liable for the whole contract. Debit-card payers can request a chargeback. Deals agreed at home also carry a 14-day cooling-off period, and the Consumer Rights Act 2015 requires work to be done with reasonable care and skill.
Get it in writing
Insist on a written contract before any work starts. It should cover the full specification (cross-referenced to the quote, not “as discussed”), the materials, start and completion dates, guarantee terms and exclusions, the payment schedule, and the snagging and sign-off process. Citizens Advice offers free template contracts.
Red flags and common scams
The most common is the “leftover material” scam — a caller claims surplus resin from a nearby job at a today-only price; genuine resin is mixed to order, so there is none left over. Walk away from unsolicited door-knocking, demands for half the money upfront, “cash only to save the VAT”, no written quote, no fixed address, a refusal to name the resin, or no insurance and no verifiable references.
