British house prices have increased 9 percent in the three months to August, according to mortgage lender Halifax.

Prices have jumped 2.7 percent in the last month, with the average price of a home across the UK now at £204,674, acording to the Halifax measure.

The Royal Institution of Chartered Surveyors (Rics) also released figures today, warning that house price inflation across the UK is ikely to hit 6% this year. At the start of 2015, Rics expected that prices would rise by just 3%.

Halifax economist Martin Ellis told the BBC that “strengthening demand, and highly constrained supply, are likely to mean that house price growth continues to be robust in the short-term.”
