UK house prices rose by just 0.1% in annual terms in January, their weakest increase in nearly six years, adding to signs of a slowdown in the country's housing market ahead of Brexit, data from Nationwide showed. 

Nationwide said the housing market's loss of momentum reflected the unusually "uncertain economic outlook".

But it said that if the UK economy grew modestly, house prices on a national level would probably grow "at a slow single-digit pace" this year.

In monthly terms, UK house prices rose by 0.3%. 

The UK is due to leave the European Union on March 29 but Prime Minister Theresa May, under pressure from her own Conservative Party, says she wants to change a key part of the withdrawal agreement she struck with the rest of the bloc. 

That has raised the prospect of an economically damaging no-deal Brexit. 

The UK housing market has slowed since the Brexit referendum in June 2016 when Nationwide estimated house prices were rising by around 5% a year. 

Surveys published today also showed that British consumers remained at their gloomiest in five-and-a-half years and businesses were also downbeat. 

Economists who took part in a Reuters poll of economists ahead of Nationwide's data had expected prices to be flat when compared with January last year and to rise by 0.2% in monthly terms.
