If you sell cars to consumers in the UK, the law governing how you describe and photograph those cars changed on 6 April 2025. Most dealers heard the name — the DMCC Act — and got on with their day. That is understandable. It is also worth ten minutes of your time, because the practical consequences for listings are real and the penalties attached to getting it wrong are larger than they used to be.
This article covers what changed, what it means for vehicle listings and photos specifically, and where AI photo editing sits relative to the new rules. It is part of our wider guide to AI car photos for dealers — what's allowed and what works.
What the DMCC Act replaced
For seventeen years, the rules on misleading sales practices lived in the Consumer Protection from Unfair Trading Regulations 2008 — the CPRs. The Digital Markets, Competition and Consumers Act 2024 replaced them. Its unfair commercial practices provisions came into force on 6 April 2025 (Section 226, legislation.gov.uk).
The substance will feel familiar if you knew the CPRs: misleading actions, misleading omissions, aggressive practices, and a list of banned practices are all carried forward. The Competition and Markets Authority has published guidance on the new regime — Unfair commercial practices (CMA207) — which is the document to read if you want the full picture.
What changed most is not the rules. It is who enforces them, and how.
The CMA's new enforcement powers
Under the CPRs, enforcement generally ran through the courts. Under the DMCC Act, the CMA can decide directly that a business has broken consumer law — no court proceedings required — and impose penalties itself. In the CMA's own words: "the CMA has the legal power to enforce some consumer laws 'directly' – meaning we (as well as a court) can decide whether a business has broken the law" (How the CMA uses its direct consumer enforcement powers, gov.uk).
The penalty for an infringement can be up to 10% of global turnover, or £300,000, whichever is greater. Failing to comply with the CMA's directions afterwards can attract further penalties of up to 5% of global turnover or £150,000 (whichever is greater), plus daily penalties while non-compliance continues (same gov.uk source).
For an independent dealer, the headline is the £300,000 floor, not the turnover percentage. The point is the same either way: misleading consumers is no longer something that only bites if a trading standards case grinds through a courtroom.
Misleading actions — the rule that covers your photos
Section 226 defines a misleading action. A commercial practice is misleading if it involves the provision of false or misleading information relating to a product, or if its overall presentation is likely to deceive the average consumer — in a way that causes, or is likely to cause, the consumer to take a transactional decision they would not otherwise have taken.
Two things in that definition matter for listings:
"Overall presentation" includes photos. Information in a listing is not just the text. A photo is a representation of the vehicle, and if the overall presentation of the listing — photos and text together — is likely to deceive the average buyer, the practice can be misleading even if every individual word is technically true.
Section 227 covers what you leave out. A misleading omission is omitting material information the average consumer needs to make an informed decision, or providing it in a way that is "unclear or untimely". A listing that simply never mentions the dent on the rear quarter, with photos angled so it never appears, is the textbook case.
If you are tempted to rely on a "photos for illustration only" line to manage any of this, read our article on what listing disclaimers actually protect you from first — the short answer is less than you would hope.
What this means practically for listing photos
The standard is straightforward to state: your photos must accurately represent the car you are selling. The buyer who travels to view the vehicle should find the vehicle the listing showed them.
In practice:
- Photograph the actual car, not a similar one from your archive, unless the listing makes that completely clear.
- Show condition honestly. Visible damage that would matter to a buyer's decision should be visible in the listing — photographing around a scuffed bumper and saying nothing is exactly the gap Sections 226 and 227 exist to close.
- Match photos to description. A description that says "immaculate" alongside photos showing kerbed alloys is an overall presentation problem.
- Keep spec accurate. Photos showing optional extras the car does not have — wheels, trim, infotainment — misrepresent the product.
None of this is new in spirit. Honest dealers have always worked this way. What is new is that the regulator can now act on the dishonest version directly, with serious money attached.
Where AI photo editing sits
This is the question we get asked most, so here is the straight answer.
Replacing the background is not misrepresenting the vehicle. The forecourt behind the car is not a material attribute of the car. A buyer's decision turns on the vehicle's condition, specification, and history — not on whether it was photographed in front of a fence or a studio backdrop. Swapping a cluttered background for a clean one does not provide false information about the product. This is the same principle that has made studio photography acceptable for decades; we cover it in full in our article on whether AI car photos are misleading.
Altering the car's apparent condition is the risk. Using any editing tool — AI or otherwise — to remove visible damage, smooth bodywork, or change the apparent colour produces a photo that misrepresents the product. That is a misleading action under Section 226 regardless of the technology used.
One practical point, because honesty is the point of this series. AI imaging tools differ in what they change. A generative tool synthesises new pixels and can alter the vehicle itself; Motuva composites the car from your own photograph and renders only the setting around it. Know which kind you are using, and check output before publishing — that is how you make sure the image you publish meets the accuracy standard the DMCC Act requires. What AI car photo editing actually changes — and what it shouldn't walks through that check in detail.
Note also that the DMCC Act is not the only set of rules touching dealer marketing — the advertising regulator has its own code, covered in our guide to ASA rules for car adverts.
The short version
The DMCC Act 2024 replaced the CPRs on 6 April 2025. The misleading-practices rules carried over; the enforcement teeth got sharper — the CMA can now decide cases itself and fine up to 10% of global turnover or £300,000, whichever is greater. For listings, the standard is the one good dealers already work to: photos and descriptions must accurately represent the car. Background editing does not breach that standard. Editing the car's apparent condition does.
If you want to know how Motuva's own process is built around that line, the FAQ gives straight answers.
