It seems to be nothing to do with 'the' Uber, it's a private company that's been owned by a couple of people apparently based at the same address in Blackpool:
UBER TRADES ONLINE DIRECTORIES LTD - Free company information from Companies House including registered office address, filing history, accounts, annual return, officers, charges, business activity
beta.companieshouse.gov.uk
My guess is that the site will last as long as it takes Uber's trademark lawyers to notice them.
