DMCC Act 2024 (Digital Markets, Competition and Consumers Act 2024)

The Digital Markets, Competition and Consumers Act 2024 (DMCC Act) is the UK statute that overhauled consumer-protection enforcement. For ecommerce, its Part 4 consumer rules — in force since 6 April 2025 — ban a list of unfair practices (fake reviews, drip pricing, false urgency), require total-price transparency, and (when secondary legislation lands) impose a new subscription regime with easy cancellation. It surfaced in this vault as the UK legal instrument sitting behind the Serial Returners / Returns Management debate about whether retailers can charge for or restrict returns. Critically, the sources gathered here suggest its returns hook is narrow — focused on subscription cooling-off, not general retail returns.

Firewall: every claim here is what a source reports. See ../../CONTEXT.md Rule 1.

What it is and who enforces it

The DMCC Act gives the Competition and Markets Authority (CMA) a direct enforcement regime — per Pinsent Masons / Out-Law (search snippet), the CMA can investigate, decide the law has been broken, order changes, and impose fines itself without first going to court Web — DMCC Act 2024 2026-06-28. Most of the Part 4 consumer-law changes have been in force since 6 April 2025 (TLT), and the CMA describes April 2025 as the launch of its new direct-enforcement regime (CMA blog, 2026-04-17).

Penalties (as-of 2026-06-28)

[!unverified] The CMA can impose fines of up to £300,000 or 10% of annual global turnover (whichever is greater), plus personal fines up to £300,000 on individuals who are an "accessory" to an infringement — Womble Bond Dickinson (search snippet); corroborated across several firms but not fetched from a primary page Web — DMCC Act 2024 2026-06-28.

Banned practices (Schedule 20)

Per GOV.UK / CMA207 guidance, Schedule 20 lists 32 commercial practices that are unfair in all circumstances (as-of 2026-06-28). The ones most relevant to ecommerce frontend and merchandising:

Banned practice	What the guidance says
Fake reviews (Sch 20 para 13)	No submitting/commissioning fake or undisclosed-incentivised reviews; no publishing reviews misleadingly; traders must take "reasonable and proportionate steps" to prevent and remove fake/incentivised/misleading reviews.
Drip pricing	Showing a headline price then adding mandatory charges as the consumer proceeds is prohibited; the total price must be in the invitation to purchase.
False urgency / scarcity	Falsely stating limited-time availability to force an immediate decision is banned.
Omitting material information	Total price and applicable cancellation rights must appear in an invitation to purchase (s230(2)); omission is unfair regardless of decision impact.

These map directly onto common conversion tactics — countdown timers, "only 2 left", "+ booking fee at checkout", and incentivised review programmes — which the Serial Returners and CRO threads in this vault touch. (See also Drip Pricing, Fake Reviews as frontier pages.)

Subscription regime (not yet in force)

The subscription-contract rules are not yet commenced and the date has slipped repeatedly.

When the rules take effect, sources report businesses must:

[!unverified] Give clear pre-contract info (price + renewal terms); provide two 14-day cooling-off periods (initial, plus a renewal cooling-off after a free/discounted trial or a 12-month+ auto-renewal — extendable up to 12 months if rights aren't disclosed); send reminder notices before renewal or trial-to-paid conversion; and make cancellation as easy as sign-up ("one-click cancellation"), online where the contract was entered online — Browne Jacobson + startups.co.uk (search snippets) Web — DMCC Act 2024 2026-06-28.

Relevance to returns

The returns connection — the reason this page exists — is narrower than the Serial Returners thread implies:

• Within the subscription regime, proposed regulations must disclose the costs to the consumer of returning goods if they cancel during a renewal cooling-off period; returnable goods get a refund including standard delivery, paid within 14 days — detail set by secondary legislation (Taylor Wessing, 2024-12) Web — DMCC Act 2024 2026-06-28.

[!unverified] The gathered sources do not indicate the Act addresses serial returners, bans them, mandates free returns, or regulates returns fees for ordinary (non-subscription) purchases. This is inferred from absence in the web synthesis (low confidence) — flagged as a gap to verify, not filed as fact Web — DMCC Act 2024 2026-06-28. The general-returns legal frame for UK retail remains the Consumer Rights Act 2015 / Consumer Contracts Regulations, not the DMCC Act.

CMA enforcement in year one (as-of 2026-04-17)

Per the CMA's "one year on" blog, in the first year (April 2025 – April 2026) the CMA:

• opened investigations into 14 businesses, settled with 2, ordered £760,000 refunded to consumers, imposed fines totalling £4.7 million, issued 157 advisory/warning letters and 46 information notices;
• ran its first public enforcement on drip pricing, fake reviews, and online choice architecture;
• on drip pricing, the AA Driving School and BSM admitted liability, refunded over £760,000 to learner drivers, and the AA was fined £4.2 million;
• on fake reviews, ran a sweep, sent advisory letters to 54 firms (90% improved policies), opened 5 investigations in March, and opened a standalone Adobe investigation into whether its early-cancellation fees are unfair and misleading Web — DMCC Act 2024 2026-06-28.

What practitioners report

Not captured this run — the Reddit and YouTube source agents returned nothing because their backends (reddit-research MCP, Apify transcript actor) were not connected. Five relevant UK law-firm / CTSI webinar URLs (Business Companion/CTSI, MBL Seminars, GSL) were located for a future transcript pass.
