Spicerhaart is threatening to sue rival chain Countrywide over what it calls “an attempt to poach its customers” before next Monday’s launch of OnTheMarket.

Spicerhaart says it will, if necessary, seek a High Court injunction, claiming that Countrywide agents have written to Spicerhaart clients claiming that Spicerhaart is withdrawing from both Rightmove and Zoopla. Three letters, apparently sent from Countrywide brands Blundells, Mann and Abbotts, have been produced by Spicerhaart (see below).

A spokesperson for Spicerhaart said last night: “Agents from Countrywide have written to Spicerhaart clients suggesting the group is withdrawing from both Zoopla and Rightmove portals.

“Spicerhaart, a founder member of OnTheMarket, in fact revealed in December that it will be retaining Rightmove as its other preferred portal, and is viewing the unsolicited approach as potentially libellous.

Paul Smith, CEO of Spicerhaart, said: “This is a scurrilous attempt to perpetrate a deliberate plan of misinformation.

“We have already announced our intention to retain Rightmove and join OnTheMarket which will be run for agents by agents, and we believe that listing all our properties on the new portal will be in the best interests of our clients.

“We predict that within a year OnTheMarket will be the second biggest portal in the UK and be the biggest in five years.”

Eye has invited Countrywide to comment.
