House prices have increased in every region in the UK for the first time in two years, as the Conservative party’s election victory and a more settled economic outlook calmed buyers’ nerves.

House price data compiled by the Land Registry showed average annual house prices increased by 2.2% in December, up from 1.7% in November.

The Office for National Statistics (ONS) said the pattern of falling house price growth since the 2016 EU referendum was reversed last summer in some regions in the north and east of England.

December was the first month since February 2018 that prices increased in all regions and countries.

The average UK house price hit £235,000, £5,000 higher than in December 2018.

London prices rose 2.3% year on year in December, which was the strongest rise since October 2017 and a second successive annual increase.

Figures last month revealed that prices increased after a surge in the sales of expensive homes in London’s most sought-after districts. In the past year 185 £5m-plus mortgages were taken out by purchasers, according to figures from the Financial Conduct Authority.

The value of those mortgages was £9.7m on average and the total was £1.8bn, an increase of £200m on the previous year.

The latest Bank of England data showed mortgage approvals for house purchases rose markedly in December to 67,241, the highest monthly level since July 2017.

Mortgage approvals in December were also most probably lifted by increased confidence and reduced uncertainty among buyers and sellers after the decisive general election result, said Archer.

Average house prices increased over the year in England to £252,000, up 2.2%, and increased by the same amount in Wales to £166,000. Average prices in Scotland were up 2.2%, to £152,000, and 2.5% in Northern Ireland.

In England, Yorkshire and the Humber registered the highest annual house price growth, increasing by 3.9% in the year to December. This was followed by the East Midlands, with a 2.8% increase.

The lowest annual growth was in the south-east, where prices rose by 1.2% over the same period. This was followed by the West Midlands, where prices increased by 1.4%.
