The UK competition watchdog has launched an investigation into hotel booking websites amid concerns they could be misleading customers.
The Competition and Markets Authority (CMA) said it was concerned about the clarity, accuracy and presentation of information on sites.
It will examine areas such as search result rankings, “pressure selling”, hidden charges, and discount claims and if it finds sites are false or misleading and breaking consumer law, could take enforcement action.
CMA chief executive Andrea Coscelli said: “Around 70% of people who shopped around for hotels last year used these sites and they should all be confident they have chosen the best accommodation for their needs and are getting a good deal.”
The CMA has written to companies across the whole sector asking for information about their practices and is also calling on customers and hotels to share their experiences.
The watchdog will examine practices such as how hotels are ranked after a customer has made a search – and whether this is influenced by a commission paid by the hotel.
It will also look at “pressure selling”, and whether claims about how many people are looking at the same room, how many rooms are left, and how long a price is available, may create a false impression or rush customers into making a decision.
Claims about discounts are to be reviewed to see if they offer a fair comparison, as will the issue of hidden charges such as taxes or booking fees which customers may be faced with in addition to the prices they are first shown.
Mr Coscelli said: “In today’s increasingly busy world, sites like this offer real potential to help holiday-makers save time and money searching for their ideal get-away.
“To do this, sites need to give their customers information that is clear, accurate and presented in a way that enables people to choose the best deal for them.
“But we are concerned that this is not happening and that the information on sites may in fact be making it difficult for people to make the right choice.”
The CMA expects to report back on the investigation by next spring.
Any enforcement action could include asking for websites to undertake to change their practices, obtaining a court order for them to do so or, if there is a breach of an order, a significant fine.
