All WD power supplies  will work between 100-240 volts, you may only need to purchase an adaptor plug for UK.  If you want an official WD power adaptor you can purchase it from the WD Store:  http://store.westerndigital.com/store/wdeu/en_GB/DisplayAccesoryProductDetailsPage/productID.198283400/categoryId.13833100
