Winkworth has acted after one of its businesses advertised a property on Rightmove, Zoopla and OnTheMarket.

By mid morning yesterday, the listing had been removed from OnTheMarket, the business having pulled off OTM to return to Zoopla.

Winkworth head office said that about a fifth of its franchised businesses have chosen not to be on OTM. However, the office that had listed the property on all three sites had been an OTM member.

A spokesperson told Eye  yesterday morning after the issue was aired on Twitter: “As individual businesses, Winkworth offices have chosen whether or not to be OnTheMarket.

“Those that have, will list their properties on both OnTheMarket and Rightmove.

“Those that haven’t become OTM members are continuing to list on Zoopla – 22 out of 100 Winkworth offices.

“It was brought to our attention this morning that one of our offices listing were appearing on all three portals so we are dealing with this immediately to ensure that they are only listing on two portals, and that this is true of all our offices.”

The £1.1m semi is with the Palmers Green office in north London and was listed on February 19.

The spokesperson later confirmed: “The office will no longer be listing on OnTheMarket. The decision was taken by this office as currently other agencies in their operating area aren’t listing on this portal.

“However, this will be reviewed by the office as OnTheMarket develops and grows.”
