Residential research analyst at estate agent Savills, Lawrence Bowles, said that house prices had dropped nationally in real terms for the first time in five years.
He said: "This month’s ONS house price index shows slowing growth, with UK house prices growing just 1.7 per cent in the year to January 2019.
"That’s compared to 4.3 per cent growth this time last year.
"It’s also below inflation for the same period – 1.8 per cent – which means UK house prices have fallen in real terms for the first time since July 2013.
"Regions in the midlands and north are still showing robust house price growth.
"Wales showed the fastest house price growth in Britain, followed by the midlands.
"Affordability in these regions is less constrained than in London and the south, which leaves more capacity for prices to rise."
