This is an adaptation of the old scam originating in the far east, as pointed out by Martinco.

UK numbers (+44 7.... or +44 8.... ) are easy to be had that can originate from any part in the world, also common among 419 scammers. Of course you may also receive official looking documents and emails, however there is a distinct danger that they have no substance once you have paid for the new registration; you and your money are forever parted with no quid pro quo.

Ignore - scam!
