ZPG, owner of Zoopla and PrimeLocation, has reported that the total number of estate agency branches that have left OnTheMarket to rejoin ZPG over the past two years has now reached more than 800.

Last week alone saw a further 16 agency branches return to ZPG, it claimed, taking the total number of rejoiners to 808.

The number includes Jeanes Holland Burnell, a multi-branch agency based in Somerset, whose director Ian Odam said: “In January 2015 we decided to join OTM.

“After two years of supporting the OTM project, we felt unable to sustain our membership with them any longer as we believed we were missing out by not listing our stock with ZPG.

“In December 2016 we relisted with ZPG and such has been the response that our offices received as many leads in the first few weeks as we received in the previous six months with OTM and is on par with the number we receive from Rightmove.”

Mark Goddard, managing director of ZPG Property Services, said: “We will welcome any agent back who is not currently on ZPG and wishes to enjoy the benefits that most of their competitors do.

“Our agent partners benefit from the most cost-effective brand exposure and lead generation as well as a wide range of tools that allow them to understand their market and customers better and generate additional revenues.”

Ian Springett, chief executive of Agents’ Mutual, which operates property portal OnTheMarket, said: “We do not comment on individual agent relationships but the facts remain the same as they did last week when Zoopla gave a similar update.

“OnTheMarket.com continues to have a positive material impact on the property portals landscape.

“Many thousands of agents switched from Zoopla / Primelocation to join us. Many thousands of agents continue to support the objectives of the business by creating a genuine alternative portal for consumers and agents alike.

“Many thousands of agents have not returned to ZPG portals with their advertising budgets and their data.

“Meanwhile, OnTheMarket.com has made impressive headway in a very challenging market, achieving millions of monthly visits with a record-breaking month of 11.2m earlier this year – an 85% year-on-year increase.

“We are concentrating on long-term growth strategy, and with regard to the legal proceedings between Gascoigne Halman and Agents’ Mutual, we shall continue to respect the Tribunal by not commenting on or around it as it completes its deliberations and prepares its judgment.”
