London hotels most expensive for Wi-Fi

Last week London was named the most expensive city in Europe for Wi-Fi access in hotels. And with some guests in the capital paying £10 for every half an hour they're online, it's easy to see why.

Posing as a potential customer, ZDNet UK's sister site, silicon.com, contacted 20 of the capital's top hotels and found a range of charges, from free Wi-Fi access for guests at the £265 per night Draycott Hotel in Chelsea to £10 for just 30 minutes of Wi-Fi access at the £455 per night Jumeirah Carlton Tower Hotel in Knightsbridge*.

Of those business-traveller class hotels we contacted, only four offered free Wi-Fi access, while the majority are charging — a practice recently branded a "rip-off" by readers of silicon.com.

Among the others we found huge disparity in how they charge for Wi-Fi access and a range of pricing models. For example, some hotels charge for half an hour, others for two hours or 24 hours, while some charge a flat rate for the duration of the guest's stay, making it difficult to compare and contrast.

Similarly there were major differences in the kind of service offered. For example, the Jumeirah Carlton Tower Hotel, while charging £10 per half-hour, told us the Wi-Fi access is only available in the lobby.

The Trafalgar Hilton meanwhile charges £15 for 24 hours' access but at least promises Wi-Fi throughout the premises, including in guest rooms.

The Four Seasons, Canary Wharf, charges a flat rate of $28 (£14.75) and offers Wi-Fi throughout — a deal that becomes relatively cheaper the longer a guest stays. The Dorchester meanwhile promises a similar level of coverage but its flat rate is £50.
