Following a meeting in London yesterday, the OntheMarket action group of disaffected members says it may take legal action against the portal over its fees.
The group says a barrister was selected at the meeting convened in an informal capacity by industry trainer and consultant Iain White.
Attended by around 100 member agencies, the main topic for debate was a perceived broken promise to 'early bird members' of the portal told subscription fees would always equal or be lower than those who joined at a later date.
"The level of outrage among Agents Mutual members who attended is significant," White said in a statement reported by Estate Agent Today.
White said Monday's information session was full and that he believes it’s "understandable that these small business owners wish to protect their interests".
“Now is the time for Agents’ Mutual to provide urgent clarity on what pricing offers it has made to attract new customers since it launched," Estate Agent Today reports White as stating.
"Affected firms are potentially out of pocket and have a portal which is not meeting their requirements, let alone achieving the success and volume of enquiries that they were promised in return for their early financial commitment."
Regional law firm, Tollers LLP has reportedly offered to represent the group together with barrister Ian Rees Phillips.
White's statement adds a steering committee has been formed to manage liaison with legal representatives on behalf of action group members and offers other agencies the chance to be included by registering at the otmactiongroup website by May 16.
Responding to the statement, an OnTheMarket.com spokesperson says the company doesn't "take lightly" the fact that agents are disgruntled.
"The broader context is that the apparent supporters of Mr. White’s ‘Action Group’ represent between 1% and 3% of our agent firms.
"The overwhelming majority of member agents remain wholly supportive of OnTheMarket.com and of our shared long-term commitment to build the best portal for consumers and agents alike.
"Regarding allegations that some agents are considering legal action against OnTheMarket.com for alleged misrepresentations made in relation to pricing policy, we have no reason to believe that there are any grounds for legal action.
"The Board and management team of Agents’ Mutual have at every stage of the company’s inception and development taken suitable legal advice.
"We continue to take appropriate legal action to ensure that agents meet their contractual obligations,"the spokesperson adds.
OnTheMarket.com announced last week that more than 6,250 UK estate and letting agent offices are now listing their properties atOnTheMarket.com.
Total support for the portal has risen to 7,000 offices, including those which are covered by Letters of Intent to list their properties at OnTheMarket.com and at a maximum of one other portal when total support is in excess of 7,500 offices.
