Why we wrote this. Written for dealerships and workshops in the UK, from the Acts and regulations on legislation.gov.uk and the regulators' guidance linked on this page, and from what automotive networks ask their auditors to check. It is a summary for audit teams, not legal advice: check the official text before acting.

What this guidebook covers

Since April 2025, the Digital Markets, Competition and Consumers Act lets the CMA decide consumer law breaches itself and fine directly, up to 10% of global turnover, without going to court. Its first fine, in April 2026, was £4.2 million over a £3 hidden fee.

This guidebook covers 6 consumer standards with 18 checkpoints: all-in pricing with no drip fees, honest reviews, accurate vehicle descriptions, the right to reject and repair, 14-day cancellation for distance sales and no pressure selling.

CON-01All-in pricing, no drip fees72 hours
The law
Digital Markets, Competition and Consumers Act 2024 (Part 4, in force 6 Apr 2025) · Consumer Rights Act 2015 · DMCCA s.226–230 misleading actions and omissions · material pricing information
What we check
Every advertised car price includes all mandatory fees (admin, preparation, delivery if unavoidable), so the price shown is the price the customer pays.
What it can cost
A £3 fee cost the AA £4.2M. For a dealer group, 10% of turnover is the ceiling.
Evidence
Screenshots + invoice sample
CON-02Honest reviewsImmediate
The law
Digital Markets, Competition and Consumers Act 2024 (Part 4, in force 6 Apr 2025) · Consumer Rights Act 2015 · DMCCA Schedule 20 banned practices: fake reviews, concealed incentivised reviews, misleading presentation of reviews
What we check
The dealership never writes, buys or filters reviews, doesn't hide negative ones, and discloses any incentive given for a review.
What it can cost
A banned practice needs no proof of harm: straight to up to 10% of global turnover.
Evidence
Review policy + platform settings
CON-03Accurate vehicle descriptions72 hours
The law
Digital Markets, Competition and Consumers Act 2024 (Part 4, in force 6 Apr 2025) · Consumer Rights Act 2015 · DMCCA s.226 misleading actions · CRA 2015 s.11 goods to match description
What we check
Adverts and descriptions accurately state mileage, service history, previous keepers, write-off category, known faults and outstanding recalls.
What it can cost
A misleading description can bring a CMA fine, a Trading Standards prosecution and the car coming back.
Evidence
History reports + listings
CON-04Right to reject and repair honoured72 hours
The law
Digital Markets, Competition and Consumers Act 2024 (Part 4, in force 6 Apr 2025) · Consumer Rights Act 2015 · Consumer Rights Act 2015 s.9–24: satisfactory quality, 30-day right to reject, repair or replace, final right to reject
What we check
Faults reported within 30 days get a full refund if the customer wants one. After that, one repair or replacement, then a final right to reject. Faults in the first 6 months are presumed to have been there at sale.
What it can cost
Refusing statutory rights leads to court claims, Trading Standards action and CMA scrutiny of the whole process.
Evidence
Complaint files + sales docs
CON-05Distance sales: 14-day cancellation7 days
The law
Digital Markets, Competition and Consumers Act 2024 (Part 4, in force 6 Apr 2025) · Consumer Rights Act 2015 · Consumer Contracts Regulations 2013: pre-contract information and 14-day cancellation for distance and off-premises sales
What we check
Cars sold online, by phone or delivered to the customer come with the pre-contract information and a clear 14-day cancellation right, with refunds within 14 days.
What it can cost
Missing cancellation information extends the right to 12 months: the customer can hand the car back for most of a year.
Evidence
Distance sale files
CON-06No pressure selling72 hours
The law
Digital Markets, Competition and Consumers Act 2024 (Part 4, in force 6 Apr 2025) · Consumer Rights Act 2015 · DMCCA s.227 aggressive practices · Sch.20 false urgency and limited-time claims
What we check
No fake deadlines, invented rival buyers, false stock claims or pressure tactics. Offers that say they end, really end.
What it can cost
An aggressive practice is both a civil breach (10% turnover) and a criminal offence.
Evidence

How to run a UK consumer protection audit, step by step

  1. Confirm what applies. Sales to consumers and sole traders are covered; business-to-business sales such as fleet are outside most of these protections.
  2. Walk the site, standard by standard. Score each of the 18 checkpoints Pass, Fail or N/A. N/A only where the standard rules it out, with the reason recorded. Compare advertised prices with what customers pay at the desk, and check how reviews are collected and shown.
  3. Capture the evidence. A pass counts only with proof captured at the time of the audit: adverts and price lists, invoices, the review process, vehicle descriptions and cancellation records.
  4. Give every fail an owner and a fix time. Record what you saw and who owns the fix. Each standard carries an ideal fix time, from immediate to 7 days, counted from audit submission (see the table above).
  5. Fix it, then prove it. The site fixes the cause and uploads proof of closure; the auditor checks the proof before closing the finding.
  6. Re-check at the next audit. Confirm closed findings stay closed, and look for the same fail at your other sites so one gap doesn't repeat across the network.
