Many of the agents closely associated with OnTheMarket are allegedly still using other portals in addition to Rightmove or Zoopla - despite the new site's one other portal only' policy.
Research by Estate Agent Today shows that as of yesterday:
Carter Jonas, Douglas & Gordon, Gascoigne & Halman, Jackson-Stops & Staff, Kinleigh Folkard & Hayward, Knight Frank, Savills, Spicerhaart, Webbers and Winkworth were still promoting their properties on home.co.uk as well as larger portals.
Carter Jonas, Jackson-Stops & Staff and Winkworth were also advertising properties on countrylife.co.uk.
Gascoigne Halman and Winkworth were also advertising on mouseprice.co.uk, while Winkworth was also on nethouseprice.com.
OnTheMarket set the cat amongst the pigeons within the industry last year when it created the only one other portal' rule; it has so far made exceptions for a Scottish lettings portal and a UK student accommodation portal, but has not commented on other exceptions.
It is still unclear how the portal ruling will be policed - if at all - and whether there is even unanimity on what constitutes a portal', or whether founding agents and those with representatives on the board of Agents' Mutual may be exempted in some way.
Early this month OTM temporarily rested' properties listed by Statons, an agency with six offices in Hertfordshire and north London, after an Estate Agent Today story said the agency had tweeted that it was not going to abide by the portal rule.
Given that many of the firms listed above and still advertising on more than one other portal are heavily involved in the running of OTM, with some having directors on the board of parent body Agents' Mutual, similar action is considered unlikely.
