TRAVEL website Booking.com is continuing to mislead consumers with pressure-selling tactics despite a crackdown by the competition regulator, according to a watchdog.

Which? carried out spot checks on six websites ordered to make changes following enforcement action by the Competition and Markets Authority (CMA) over concerns of pressure selling, misleading discount claims, the impact of commissions on search results and hidden charges.

The regulator concluded that practices such as giving a false impression of a room’s popularity or not displaying the full cost upfront could potentially break consumer protection law.

It gave the websites – Expedia, Booking.com, Agoda, Hotels.com, ebookers and Trivago – until September 1 to comply.

However Which? found five out of 10 claims of “only one room left” on Booking.com failed to give an accurate picture of availability, and said the regulator “will have to step in” if cast-iron guarantees of improvements were not made.

In one example, search results for the Park Plaza Westminster Bridge warned that just one “secret deal” room was available – a superior double room with disability access priced at £232.

However, after clicking through to the booking page, Which? found another 10 superior doubles with internal view available for a cheaper rate of £226.

In total, 34 empty rooms were still available at the same hotel on the same night.

In contrast, the five other sites named by the CMA appeared to be complying with the rules, the consumer group said.

A Booking.com spokeswoman said: “We have worked hard to implement the commitments agreed with the CMA and maintain continuing collaboration and dialogue to inform ongoing enhancement of the consumer experience.”
