The average price of a property in the UK was £225,956 in August, up from £218,964 the previous August.
House prices rose 0.5 per cent month-on-month.
EMoov.co.uk chief executive Russell Quirk says: “This latest index provides the most compelling evidence yet that the UK property market has been able to shake off the woes of the previous year and snap election, to see positive growth during the summer months.
“The rate of growth during this period is higher than previously reported by Halifax and Nationwide, which is impressive given that this price data usually lags slightly behind other industry sources that base their figures on mortgage approvals rather than sales completions.”
Nationwide said August house price growth was 2.1 per cent, compared to 2.9 per cent in July.
