Relations between Zoopla and OnTheMarket deteriorated today with news that an agent planning to re-join Zoopla from OnTheMarket has not done so.

The matter came to light this morning, two days after Zoopla announced that Henry Adams, with 15 offices in West Sussex, Hampshire and Surrey was leaving OTM to rejoin it. EYE carried the story yesterday.

This morning, an OTM spokesperson released this statement: “We noted media coverage on 15 November 2017 that Henry Adams had signed an agreement with Zoopla to list all of its properties on its websites.

“As at 16 November 2017, Henry Adams is not listing its properties on any of the ZPG websites.

“The firm continues to list its properties at OTM in accordance with its current listing agreement and remains a valued member.”

At lunchtime, Zoopla hit back with a statement saying: “Henry Adams voluntarily re-joined ZPG but has subsequently been threatened with legal action by OTM for doing so.

“It is an unfortunate state of affairs for OTM that the only way they can retain their customers is by threatening to sue them and preventing them from maximising their opportunities.”

Today’s clash follows litigation between OTM and Connells’ brand Gascoigne Halman. OTM won the courtroom battle as to the legality of its ‘one other portal’ rule.
