Travel Experts Warn UK Tourists About Misleading Online Reviews for Holiday Bookings

UK travellers are being warned not to trust
Review verification specialist TruthEngine says up to 50% of reviews in competitive sectors like travel may be "not genuine," according to Wales Online. The company's CEO, Daniel Mohacek, says a near-perfect score is itself a red flag. "A near-perfect review score doesn't mean a property is exceptional," he said. "Savvy consumers will trust what doesn't shine quite so brightly."
Many online reviews are exaggerated, outdated, or paid for — a practice now illegal in the UK. The Digital Markets, Competition and Consumers Act (DMCC), which came into force in April 2025, makes it a crime to post or commission fake reviews. Companies caught breaking the rules face fines of up to 10% of their global annual turnover, according to Coventry Telegraph.
Despite the law, a recent audit found 0% full compliance among 100 consumer-facing websites tested 12 months after the rules took effect. The Competition and Markets Authority (CMA) spent 2025 warning firms. Now it is prosecuting them. In March 2026, the CMA launched formal investigations into five companies, including Just Eat and Autotrader, according to Cheshire Live.
TruthEngine recommends a simple check before booking any property. Compare the same listing across Google, TripAdvisor, Booking.com, Airbnb, and Expedia. Then check social media tags for real traveller photos. The whole process takes about 30 seconds, according to Coventry Telegraph.
Mohacek also advises starting with two, three, and four-star reviews — not five-star ones. These mid-range reviews tend to be the most honest. They flag specific problems without being driven by anger or incentives. Relying on just one booking platform is one of the most common mistakes travellers make, he said, according to Daily Post.
TruthEngine has introduced what Mohacek calls the "fair-exchange" theory. He argues that truly happy customers often say nothing online — their expectations were simply met. When a property has a massive volume of high-praise reviews, that pattern often signals a coordinated campaign, not genuine satisfaction, according to Cambridge News.
AI tools have made the problem worse. Large language models can now produce grammatically perfect, convincing reviews at scale. Before 2024, the UK had no specific law against fake reviews. The DMCC Act changed that — but enforcement is still catching up with the technology, according to My London.
In January 2026, Google signed official undertakings with the CMA to better detect and remove fake reviews. That came after the CMA sent 54 advisory letters to major UK firms across 14 sectors in July 2025. The regulator's chief executive, Sarah Cardell, said fake reviews "strike at the heart of consumer trust," according to Wales Online.
TruthEngine closed a Series A funding round on June 12, 2026 — just days before issuing its summer holiday warning. The company offers a "TruthMark" accreditation for businesses that want to prove their reviews are clean. Lead investor Tom Wood said review manipulation is now illegal in more than 30 markets, adding that "TruthEngine has built technology businesses are only just beginning to understand," according to Cheshire Live.
