cPanel is now available in London, the order forms have been updated and are available today. Please note however that you must be a UK/EU resident to order this plan.
The resources are not quite as generous as recent pricing changes with cPanel mean it is a cost for every website added so the plan is limited to a single website. No other control panel limitations.
Although not quite as generous an offering as the plans available on DirectAdmin, there are more features on offer for those that require them.
