If you’ve ever bought a pair of trainers online because they had 4.8 stars and 2,000 glowing reviews, only to find them falling apart within a fortnight, congratulations, you’ve almost certainly been stung by fake reviews. It’s one of the most persistent problems in British online shopping, and for years regulators have been playing catch-up. That’s about to change. The fake reviews crackdown in the UK is no longer just a threat; it’s becoming law, and the platforms we all use every day are firmly in the crosshairs.
What Ofcom and the CMA are actually doing
The Competition and Markets Authority has had fake reviews on its radar for a while. Back in 2021 it estimated that around £23 billion of UK consumer spending is influenced by online reviews each year. That’s an enormous amount of purchasing power being shaped by ratings that could, in many cases, be entirely invented or paid for.
Under the Digital Markets, Competition and Consumers Act 2025, both the CMA and Ofcom received significant new teeth. The CMA can now directly fine platforms that host or facilitate fake reviews, without needing to take them to court first. We’re talking fines of up to 10% of global annual turnover for serious breaches. For a business like Amazon UK or Trustpilot, that’s not pocket change. Ofcom’s role is slightly different; it covers the broader Online Safety Act obligations, which include requirements for platforms to be transparent about how user-generated content, including reviews, is moderated.
The rules aren’t fully live yet, but the CMA has made clear that enforcement is coming in 2026, and platforms have been put on notice. I’d say this is one of those rare occasions where British regulators are moving faster than most people realise.
Which UK retail sites are most affected?
Amazon is the obvious one, and it knows it. The platform has invested heavily in its own review-detection systems, but independent researchers keep finding coordinated fake review rings that slip through. Amazon UK seller forums are full of complaints about competitors gaming the system with verified purchase fraud and review clubs.
Trustpilot, while not a retailer itself, sits right at the heart of this. Thousands of UK businesses use Trustpilot badges to build trust, and the platform has faced sustained criticism over how easily businesses can invite only happy customers to leave reviews (a practice called “review gating”), while suppressing the negative ones. Trustpilot has been working with the CMA, but its model still has obvious structural tensions.
Google’s local reviews are similarly tricky. Type any high street service into Google Maps and you’ll see wildly inconsistent review counts, some clearly padded, others suspiciously sparse. The CMA’s new powers apply here too, and Google has reportedly been in discussions about what compliance looks like.
Smaller players, comparison sites, niche marketplaces, certain travel booking platforms, face the same obligations but often have fewer resources to implement robust detection. That’s where I think the real enforcement action will get interesting.
The ghost brand problem makes this worse
Here’s a wrinkle worth knowing about. A chunk of fake reviews aren’t attached to real, established brands at all. They’re attached to what I’d call shadow products, items sold under invented brand names, often manufactured identically to other products but marketed through fake social proof. I’ve written before about the UK’s booming ghost brand economy, and the fake review problem is deeply intertwined with it. A brand that doesn’t really exist has nothing to lose from faking 800 five-star reviews.
Likewise, the Companies House crackdown has revealed just how many online sellers are operating through shell businesses with minimal accountability. If you’re curious how that connects, the scale of fake UK business registrations is genuinely staggering. Fake reviews and fake businesses often go hand in hand, which means the regulatory net being cast in 2026 is catching multiple problems at once.
How to spot dodgy reviews before you buy
While the regulators do their work, you still need to shop today. Here are the things I actually check before handing over my card details.
Look at the review curve. A genuine product usually has a spread, some threes, some fours, a handful of very unhappy ones. A product with 94% five-star reviews and almost nothing else is almost always suspicious. Real customers are rarely that uniformly delighted.
Check the review dates. A sudden burst of fifty reviews posted within a week, after months of nothing, is a classic sign of a bought-review campaign. Most platforms show review dates if you dig into them.
Read the one and two-star reviews first. This is the most useful habit I’ve developed. Negative reviews tend to be more specific, more detailed, and harder to fake. If the complaints are consistent (“zip broke after two uses”, “completely different colour to the photo”), take them seriously.
Use a browser extension. Tools like Fakespot (now integrated into some browsers) and ReviewMeta analyse review patterns automatically and flag suspicious products. They’re not perfect, but they’re genuinely useful.
Cross-reference elsewhere. If a product has brilliant reviews on Amazon but nothing on Reddit, nothing on specialist forums, and no YouTube unboxings despite supposedly selling thousands of units, that absence of organic discussion is itself a signal.
It’s also worth being wary of online scams more broadly. Digital deception takes many forms, the writer 0lly has documented how fraudulent invoices and fake domain renewal notices use similar psychological tricks to manipulate people into acting quickly without thinking. The same urgency-and-trust manipulation underlies both fake reviews and other online cons.
Will the crackdown actually work?
I’m cautiously optimistic, which is not something I say about regulatory action very often. The combination of direct financial penalties without the need for court proceedings, plus Ofcom’s transparency requirements, genuinely changes the incentive structure for platforms. Previously, the cost of ignoring the problem was low. Now it isn’t.
The harder challenge is the global nature of the supply chain. Many fake review operations are run from outside the UK, using international seller accounts and review farms with no UK presence. The CMA can fine Amazon UK for hosting problematic reviews, but it can’t directly regulate the seller in another country who paid for them.
Still, making the platforms financially responsible for what appears on their sites is the right move. It’s how the UK pushed through meaningful change on online safety more broadly, and there’s no reason it shouldn’t work here too. The platforms have the technology to do better, they’ve just lacked sufficient motivation.
For now, keep your wits sharp when shopping online. The rules are tightening, but the most reliable protection you have is still your own scepticism.
Frequently Asked Questions
When does the UK fake reviews law actually come into force?
The Digital Markets, Competition and Consumers Act 2025 gave the CMA powers to enforce against fake reviews, with active enforcement expected throughout 2026. The CMA has signalled it will prioritise the largest platforms first, so compliance pressure on major retail sites is already building.
Which platforms does the fake reviews crackdown cover in the UK?
The rules cover any platform that hosts consumer reviews and operates in the UK market, including Amazon, Google, Trustpilot, comparison sites, and niche marketplaces. Platforms can be fined up to 10% of global annual turnover for serious or repeated violations.
How can I tell if a product's reviews on Amazon are fake?
Look for an unnaturally high concentration of five-star ratings, a suspicious burst of reviews over a short period, and very generic language that never references specific product features. Browser extensions like Fakespot can help automate this check.
