Halifax released its house prices data for the U.K. on Wednesday. House prices in the U.K. increased 1.7% in June, after a 0.3% rise in May. May's figure was revised up from a 0.1% decline.

On a yearly basis, house prices climbed 9.6% in three months to June, after a 8.6% increase in three months to May. It was the fastest pace since September 2014.

"Economic growth, higher employment, increasing real earnings growth and very low mortgage rates are all supporting housing demand," Halifax's housing economist Martin Ellis said.
