The Bank of England Governor Mark Carney said on Wednesday that the outlook of U.K. financial stability worsened due to the Greek debt crisis, but UK banks' direct exposure to Greece is very small.

"The footprint of Greek banks in the United Kingdom is tiny compared with the size of our economy. In contrast, our economic and financial exposure to the euro area is considerable," he noted.

Carney also said that the economic growth in the U.K. has been solid and the burden of household debt has continued to decline.
