Residential research analyst at estate agent Savills, Lawrence Bowles, said: “The average UK house price rose by 1.2% in the year to May 2019, down from 1.5% in the year to April.
“London stands out this month as the nation’s worst performing region: prices there fell 4.4% compared to this time last year. The North East also saw prices fall 0.7% year-on-year, a reversal from annual growth last year of 1.4%.
“In every other region prices increased. The North West saw the strongest annual growth, followed by Wales and Scotland at 2.8%.
“With house prices lower relative to earnings, lower deposit requirements, and strong economic growth prospects, we would expect to see stronger growth in the North, particularly the North West, over the next few years.”
Between April last year and March this year, the most recent 12 months for which sales volume data is available, 2,345 homes were sold in Caerphilly , 12.6% fewer than in the previous year.
