UK house price inflation at +7.8% Average UK house prices rose by 0.9% in the three months to January, taking the rate of annual growth to 7.8%, down from 8% in December. Price growth gained momentum during most of 2021, after one of the busiest years the market had ever experienced. But with the lowest level of quarterly house price growth since August 2020, there are signs now that price growth is starting to ease, although the path will not be linear.
