The short answer
Choose a resin driveway installer by verifying their previous work (ideally 5+ years old), confirming they use a UV-stable aliphatic polyurethane resin and a forced-action mixer, and ensuring all specifications are in writing before you sign anything. BALI membership or equivalent trade body accreditation is a useful indicator but not a guarantee. See best resin for driveways for the product specification questions.
The quality of your resin driveway is determined more by the installer than by almost any other single factor. Resin-bound surfacing is a skill-intensive process with a very short working window; the difference between an experienced, well-equipped team and an inexperienced one is often the difference between a driveway that lasts 20 years and one that fails in two. This guide gives you the practical checklist for evaluating any installer before you commit.
Installer selection at a glance
- Trade body BALI member or Marshalls-approved preferred
- Mixer type Must use forced-action (paddle) mixer — not drum
- Resin specification UV-stable aliphatic polyurethane — ask for data sheet
- Previous work Ask for references from driveways 5+ years old
- Quote format Written, itemised specification — not just a total price
- Insurance Public liability insurance — ask for certificate
The non-negotiable questions to ask every installer
Before inviting any installer to quote, or before accepting any quote they provide, ask these questions. A quality installer will answer clearly and without hesitation; vague or evasive answers are a warning sign:
- What resin system do you use? Ask specifically whether it is aliphatic (UV-stable) two-part polyurethane. Request the product data sheet. See best resin for driveways.
- What mixer will you use? The answer should be a forced-action (paddle) mixer. A drum mixer or hand-mixing is inadequate for resin-bound work.
- Can you show me work from five or more years ago? New installations look good whatever the skill level; older work shows how the system weathers.
- What base preparation does your quote include? Primer, crack repair, cleaning — all should be itemised.
- What is not included in this quote? Skip hire, base repair beyond normal, drainage work — understand what will be charged extra.
- Are you insured? Ask for the public liability insurance certificate.
| Factor | Good sign | Warning sign |
|---|---|---|
| Mixer type | Forced-action (paddle) | “We mix by hand” or drum mixer |
| Resin chemistry | Aliphatic polyurethane, data sheet provided | Vague; refuses to name product |
| Previous work | References from 5+ year-old driveways | Only shows new work or brochure photos |
| Quote format | Written, itemised specification | Verbal quote or just a total figure |
| Insurance | Certificate on request | Hesitant or unable to provide |
| Pricing | Within market range for specification | Significantly below market — check what is missing |
Trade body accreditation
Membership of BALI (British Association of Landscape Industries) or approval by a resin manufacturer’s approved-installer scheme (such as Marshalls Approved or SureSet Approved) indicates that the installer has met training and standard requirements. These are useful filters but not absolute guarantees: an accredited installer can still have a bad day, and a non-accredited specialist may do excellent work. Use accreditation as one factor in the assessment, not the only one. Check that membership is current on the trade body’s website, as listings can include lapsed members.
Deposits and payment terms
A reasonable deposit for a resin driveway is typically 10–25% on signing, with the balance due on satisfactory completion. Avoid any installer who requests the full payment upfront or who is reluctant to provide a written contract with payment terms. For a £4,000 driveway, paying a £500–£1,000 deposit is reasonable; paying £4,000 upfront to an unknown contractor is not. If using a credit card for the deposit (over £100), you gain Section 75 protection under the Consumer Credit Act if the contractor fails to perform. This is general information, not financial or legal advice.
Get quotes from vetted local installers
Compare written quotes from local resin driveway installers. Include your size, current surface and aggregate preference when enquiring so each installer quotes on the same basis.
Frequently asked questions
Is a BALI-approved installer better?
BALI membership indicates training and standards have been met, which is a useful indicator of quality. Always verify current membership and still ask the practical questions about resin type, mixer and insurance.
How many quotes should I get for a resin driveway?
Three written quotes minimum, each with a full specification. This gives you enough comparison to identify whether low prices reflect reduced scope and whether quotes are on a like-for-like basis.
What should a resin driveway contract include?
Total price, m² to be surfaced, resin system and aggregate specification, minimum depth, base preparation scope, start and completion dates, payment terms and what happens if base problems are found.
Can I check whether a contractor has complaints against them?
Check Trustpilot, Google Reviews and Checkatrade. For members of BALI, you can verify current membership at bali.org.uk. Also check Companies House to confirm the business is registered and active.
