Zoopla's positive update matched the confident outlooks from British housebuilders Barratt Developments and Redrow in recent days.

Housing market strength was also apparent in data from the Royal Institution of Chartered Surveyors which said on Thursday that its monthly house price index jumped to +12 in August from July's three-year low of +5, the first rise in six months.

For the year to Sept. 30, Zoopla said its core earnings (EBITDA) would be at the top end of a 69 million pounds to 76 million pound range from a poll of analysts.
