One possible problem for OnTheMarket and its agents this morning is that properties might still be appearing on Rightmove and/or Zoopla.

By last Friday afternoon’s press conference, it was said that properties were still on other portals, despite agents ending their contracts under the “one other portal” rule.

OTM boss Ian Springett said: “We will only know on Monday and through the week, what the situation is.”

Asked how OTM will police the “one other portal” rule, Springett said that regional teams would keep an eye out, but that he expected it to be largely self-policing.

In addition, he said, there would be a “data driven solution”.
