Shares in Zoopla rose 10% yesterday after its outstanding half-year results, showing a 130% rise in revenues driven by performance at its comparisons website business uSwitch.

The business was acquired last May and delivered a performance ahead of expectations, with 46% revenue growth.

William Packer, analyst at Exane BNP Paribas, said uSwitch was now worth £500m, against the £190m Zoopla paid for it only 12 months ago.

He said the strong performance adds to Zoopla founder Alex Chesterman’s “impressive” track record regarding mergers and acquisitions.

However, Packer said that momentum at Zoopla’s property portal business was “subdued”.

Property services revenues at Zoopla declined 8% organically, he said.

However, he said: “More encouragingly, the group (again) talked up the prospects for an acceleration in returning members from Agents’ Mutual, although we note there are conflicting reports in the industry as to progress.”

Exane said it remained neutral on Zoopla, saying that the group was trading “at a premium to Rightmove despite less favourable competitive/structure dynamics. Agents’ Mutual’s Letter of Intent Strategy remains a sting in the tail risk.”

Zoopla shares rose to 337p.
