Does this apply to me?
The DMCC Act applies to virtually any business selling to UK consumers, across every channel. It matters for:
- Pricing and how prices are presented — including any mandatory fees
- Online reviews and testimonials
- Advertising claims of all kinds
- Subscription traps and auto-renewals
It is enforced directly by the Competition and Markets Authority (CMA). The headline change is that the CMA can now investigate, rule and fine firms up to 10% of global annual turnover without first going through the courts — a power it did not previously hold.
Key rules
The provisions that matter most for advertisers:
- No drip pricing. The total unavoidable price, including mandatory fees, must be shown upfront — not revealed later in the journey.
- No fake or misleading reviews. Commissioning, hosting or failing to remove fake reviews is banned.
- No misleading actions or omissions, carrying over the long-standing unfair trading principles.
- Clear subscription information and straightforward cancellation.
Common breaches
The practices now firmly in the CMA's sights:
- Drip pricing — adding compulsory booking, service or admin fees after the headline price.
- Fake and incentivised reviews presented as genuine.
- Pressure selling — false urgency, countdown timers and fake scarcity.
- Subscription traps — hard-to-cancel or auto-renewing contracts.
