The World of Warcraft monthly subscription fee in pounds sterling will increase this November to coincide with the launch of upcoming expansion Warlords of Draenor.
A 30-day game time subscription will increase from £8.99 to £9.99 in the UK, while a three-month subscription will cost £28.17 and players will be charged £52.14 for six months.
The suggested RRP for a two-month pre-paid game card will be £20.99.
Developer Blizzard has guaranteed players with auto-renewing subscriptions at the time of the price change will retain their current price for two years.
"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," said a Blizzard community manager.
"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.
"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."
Warlords of Draenor will hit UK retail shelves - and be available to download digitally - on November 13th.
