He said the number of monthly sales agreed to in Britain was the highest since he started tracking the figure a decade ago, up 38% from the same period last year and with a combined total value of over £ 37 billion.
Potential sellers were also active, with more properties coming onto the market than in any month since 2008.
Asking prices fell an average of 0.2% across mainland Britain, but this was due to a 2% drop in London, where the number of homes put on the market is up 69% from year after year. In seven regions, asking prices hit record highs as sellers sought to make the most of demand.
The housing market was locked out and reopened in mid-May, sparking a wave of activity. In July, stamp duties were canceled on houses costing up to £ 500,000 in England and £ 250,000 in Wales and Scotland, further fueling activity.
