An email sent out to agents by Zoopla has confirmed that, if the flotation goes ahead, they will be able to buy up to £2,500 worth of shares per branch – and the same again next year, provided they remain a “loyal” member.

The email also confirms the 20% discount and says that the minimum investment that can be made by agents is £500.

Those who decide to make that minimum investment of £500 would be allocated £625 worth of shares.

The email, from Zoopla chief executive Alex Chesterman, makes clear that the IPO has not yet launched, and that when it does, a prospectus will be published.

The email adds: “We thank you for your ongoing loyalty and we continue to dedicate ourselves to ensuring that we remain your most valued digital partner.”

The Sunday Times carried a report at the weekend under the headline “Zoopla to buy agents’ loyalty”.

The piece, by Simon Duke, said that the 20% “cut-price deal has been widely viewed as a ploy to stymie a new housing portal…

“Agents’ Mutual aims to break the iron grip exerted by Rightmove and Zoopla over internet property search.”

Meanwhile, in a post on Eye at the weekend which appears on an earlier story about Zoopla, a reader says that in south-west Wales, a group of Agents’ Mutual agents has formed to decide en masse which portal to ditch – Rightmove or Zoopla.

The group says that several agents have suggested dropping both, to concentrate wholly on Agents’ Mutual.
