Halifax, part of Lloyds Banking Group, said that house prices in December fell by 0.6 percent after rising by 0.9 percent in November, itself a smaller increase than initially estimated.

House prices in the three months to December were 7.5 percent higher than a year earlier, a slightly smaller rise than the month before.
