There was speculation yesterday about the lack of properties put up by Purplebricks on Zoopla.

By last night, no new properties had been uploaded, with the last ones showing as having been listed on Monday, when 33 new listings appeared.

Despite the lack of Purplebricks properties on Zoopla yesterday, new listings continued to appear on Rightmove.

Various colourful theories appeared, including that Purplebricks had bought Rightmove, had decided to dispense with all property portals because it is bigger than all of them, or dropped Zoopla to join OnTheMarket which has, after all, been busy recruiting new members.

There was, however, a more prosaic explanation last night from Purplebricks: blame the computers.

“There was a technical issue,” said a spokesperson. “Our IT team has been liaising with Zoopla’s.”

The market did not appear to notice. Shares in Purplebricks lifted yesterday, closing 5% up at 336p.
