These statistics, which include data based on mortgage completions during the month of December 2008, also revealed that UK house prices fell by 6.4% in the quarter ending December 2008.
This compares with a fall of 3.0% for the quarter ending September 2008.
Commenting on the figures, Howard Archer, chief UK and European economist at IHS Global Insight, said: "We certainly expect house prices to continue to fall for some considerable time to come.
"Powerful negative downward forces on housing market activity and prices continue to come from ongoing very tight credit conditions, sharply rising unemployment (and) slowing income growth."
The UK average house price drop of 10.2% in the year to December 2008, compared with a fall of 8.5% in the year to November 2008.
