A fake review is a consumer review that does not reflect a genuine experience, and it is now illegal under UK law. Since April 2025, the Digital Markets, Competition and Consumers Act 2024 bans businesses from writing, commissioning or hosting fake reviews. The Competition and Markets Authority can act directly against businesses that break these rules. Penalties reach up to 10% of global annual turnover. The Advertising Standards Authority and the Information Commissioner’s Office can also act where reviews mislead consumers or misuse personal data. This article will explore the primary legal risks to your UK eCommerce business of utilising fake customer reviews.

What are ‘Fake’ Online Reviews?

Online reviews are a crucial part of the online shopping experience, and research has shown that over 90% of consumers read online reviews before purchasing. As a result, many eCommerce businesses go to great lengths to generate positive reviews for their products and services.

Unfortunately, some business owners resort to fraudulent reviews to manipulate their online reputation. The practice of faking online reviews is known as review fraud. This can involve creating fake accounts to post positive reviews or paying individuals to post fake reviews. Review fraud can also include deleting negative reviews, which can mislead consumers and violate their trust.

Let us now consider the legal risks of faking online reviews.

1. Breach of Competition Law

Faking online reviews can constitute a breach of competition laws. This is because fake reviewers can distort the market and create unfair competition, leading to a disadvantage for honest businesses.

The Competition and Markets Authority (CMA) has stated that businesses that use fake reviews to promote their products or services may breach consumer protection and competition law. One of the CMA’s primary purposes is to encourage a level playing field and ensure businesses that comply with the relevant rules are not disadvantaged.

Since 6 April 2025, the rules on fake reviews are no longer guidance alone. The DMCC Act makes it a banned practice to write, commission or host fake reviews. It also bans publishing incentivised reviews without clearly disclosing the incentive. This means common tactics carry real legal risk. Offering a discount or prize draw entry for a five-star review is unlawful unless you clearly flag it. Hiding paid reviews among genuine ones is also banned.

The CMA can now fine businesses directly, up to 10% of global annual turnover. It does not need to go to court first. To stay compliant, audit how you collect reviews, train staff who manage feedback, and add a clear policy on incentivised reviews. Treat every review as something a regulator could inspect.

2. Breach of Advertising Standards

Faking online reviews can also breach advertising standards set by the Advertising Standards Agency (ASA). The ASA is an independent regulator that enforces advertising standards in the UK. They have issued guidelines for online reviews, which require businesses to ensure that reviews are genuine and unbiased.  

The ASA can investigate any form of advertising deemed misleading, false or exaggerated and may lead to legal action. In particular, the ASA has the power to investigate complaints and take enforcement action against businesses that violate the code, including fines, sanctions and restrictions on advertising.

Key Statistics

  1. £23 billion: UK consumer spending a year is potentially influenced by online reviews.
  2. 89%: UK adults use online reviews when researching a product or service.
  3. 10%: Fines reach up to 10% of global annual turnover for consumer protection breaches.

3. Data Protection Issues

Faking online reviews can also breach data protection laws. Your business must comply with the General Data Protection Regulation (GDPR) and collect, process and store personal data securely and transparently. This includes data collected from individuals who post reviews regarding your products and services on your website.  

Businesses that engage in faking online reviews collect personal information from people to create fake reviews. This personal data may include the following: 

The collection of personal data for this purpose is subject to data protection regulations, and businesses must obtain the explicit consent of real customers before publishing online reviews.

Misusing personal data can result in hefty fines of up to £17.5m from the Information Commissioner’s Office (ICO). Moreover, it can significantly damage your reputation. Ultimately, this defeats the purpose of falsifying good reviews to increase your bottom line, as you will pay out hefty financial penalties to the ICO.

4. Harm to Your Company’s Reputation

Fake online reviews can also harm your business’s reputation and credibility. Consumers are becoming increasingly aware of review fraud and quickly spot fake positive reviews. If your company engages in review fraud, it can damage your brand’s reputation and lead to losing customer trust.  

Rather, aim to prioritise transparency and honesty in your online marketing. For example, encourage genuine customer reviews and respond to negative feedback constructively. By building a reputation based on honesty and trust, you can establish a loyal customer base and sustainably grow your business.

Key Takeaways

In summary, faking online reviews may seem like a quick and easy way to improve your eCommerce business’s reputation. However, the legal risks of doing so can be severe and can negatively impact your business in the long run. To avoid these risks, you must prioritise transparency and honesty in your online marketing and build a reputation based on trust and credibility.

Frequently Asked Questions

Can my UK business pay customers to leave five-star reviews?

No. Paying for five-star reviews is banned under the DMCC Act. Offering incentives without clearly disclosing them counts as a fake or misleading review. You must clearly mark any incentivised review and base genuine feedback on real customer experiences.

What penalties can my business face for fake reviews?

The CMA can fine businesses up to 10% of global annual turnover for consumer protection breaches, including fake reviews. Directors and managers can face personal fines or up to two years in prison for serious unfair commercial practices.

How do I encourage genuine reviews without breaking the law?

Ask every customer for feedback after a purchase through automated requests or follow-up emails. Respond to all reviews professionally. Never post your own reviews or offer hidden incentives, as this likely breaches consumer law.

How can you differentiate between genuine reviews and false reviews?

The main way is to consider the most recent reviews together and examine whether they share too many similarities (such as the style of writing, number of stars or name of the ‘reviewer’)
