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. A sound specification and competent installation reduce the risk of cracking, yellowing and ponding.
Accreditations to look for
Because there is no single trade licence, independent checks and manufacturer training can help. Look for installers listed by the named resin-system manufacturer and verify what that status actually covers, including any current warranty terms. Useful national schemes include TrustMark (the Government-endorsed quality scheme), Buy With Confidence (vetted by Trading Standards), and BALI (British Association of Landscape Industries). Re-check every badge on the scheme's own website and still assess the quote, insurance, references and contract yourself.
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: a site-specific explanation of whether the existing base is suitable or must be excavated. A complete permeable new build commonly uses a compacted open-graded sub-base such as MOT Type 3; an overlay needs written system approval and a drainage plan.
- 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: the named system’s specified thickness for the aggregate and vehicle load, with turning areas considered.
- How will the complete build drain? Look for: a base and surface designed together, with on-site drainage and local planning requirements checked rather than a claim that resin alone guarantees compliance.
- What guarantees do you offer? Look for: separate written workmanship and product terms, their exclusions, who provides them and whether any cover is independently insured.
- 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 legal trading name and address, a company number if incorporated, and VAT details if VAT-registered; 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 including any applicable VAT. Be wary of vague “quality resin”, a price far below everyone else, or no clarity about whether VAT is included.
Deposits and your consumer rights
There is no universal safe deposit percentage. Agree a written payment schedule tied to identifiable materials and completed work, with a final payment after the agreed checks. Ask how any advance payment is protected and avoid large cash deposits. Section 75 of the Consumer Credit Act can make a credit-card provider jointly liable for a supplier's breach of contract or misrepresentation when the cash price is over £100 and up to £30,000. Paying only a deposit by credit card can be enough, but the statutory criteria must be met, including the required debtor-creditor-supplier relationship. See MoneyHelper's Section 75 guidance. Debit-card users may be able to request chargeback, which is a card-scheme process rather than the same statutory protection.
Contracts agreed online, by phone or at your home normally have a minimum 14-day cancellation period. If you expressly ask for work to begin during that period, you may have to pay for work properly completed before cancellation. A contract agreed at the trader's premises does not automatically carry the same change-of-mind right. The Consumer Rights Act 2015 also requires the service to be performed with reasonable care and skill. See Business Companion’s off-premises contract guidance for the conditions and exceptions.
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.
Pre-hire checklist
- Found through an approved-installer scheme, not a door-knock
- At least three written quotes from separate firms
- Legal trading name and address obtained; company/VAT details checked where applicable
- Public liability insurance certificate seen
- Resin named and confirmed UV-stable; wearing-course depth in writing
- Site-specific base preparation and drainage plan confirmed in writing
- Itemised quote with m², materials, waste removal and any applicable VAT
- Written contract signed; final payment on sign-off; guarantee provider and terms verified
- Modest deposit and staged payments agreed; no cash-only demand
