LONDON--U.K. house prices grew in October following a slump in the immediate aftermath of Britain's June 23 vote to leave the European Union, a survey of property brokers showed Thursday.

The Royal Institution of Chartered Surveyors said its price indicator stood at plus 23 in October, up from a reading of plus 18 in September. The higher reading means a bigger percentage of property brokers reported a price increase compared with those reporting a decline.
