We regularly look at our pricing around the world and from time to time we make changes in light of local and regional market conditions. As such, we want to give everyone a heads-up that we will shortly be adjusting the pound sterling subscription price of World of Warcraft.

The new price for recurring subscriptions will be £9.99 for one month, £28.17 for three months (£9.39 per month), and £52.14 for six months (£8.69 per month). The suggested retail price of the 60-day prepaid time card will be £20.99.

As a thank you for current World of Warcraft subscribers, we guarantee that players with recurring (auto-renewing) subscriptions at the time of the price change will retain their current price for two years, as long as they remain in the same recurring subscription without interruption. This applies to anyone who is already in, or signs up for, a recurring subscription prior to the price change, which is scheduled to take place at the Warlords of Draenor release. We will reach out to relevant players approximately two months prior to the price change with a reminder.

Edit: The wording when referring to the subscription time periods in this post has been updated for consistency, i.e. 30 days is now 1 month.
