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."
Between December 2017 and November last year, the most recent 12 months for which sales volume data is available, 3,318 homes were sold in Calderdale, 2 per cent fewer than in the previous year.
The highest house prices in the country in December were found in London's Kensington and Chelsea, where properties sold for an average of £1.41 million – 18 times the cost of a home in Burnley, where the average property cost just £78,000.
