Agents’ Mutual, which will be launching its OnTheMarket portal in January, announced this morning that it has now passed the 3,000 membership milestone.

Chief executive Ian Springett told Eye: “The next major milestone is 4,000. Once we hit this, we will approach our Silver agents, who have signed letters of intent, to sign contracts. At current recruitment rates, this will be early autumn.”

Springett also revealed that although the current Gold offer closes on July 31, there is a possibility of a further Gold offer after that.

The original Gold agents who signed up did not have to sign contracts until the 2,000 member office mark was reached. Those who have been recruited since have gone straight to contract.

In addition, Silver members have the option to upgrade to Gold and Springett says that a number of agents are making the switch.

He said of the next goal: “The objective is to have at least 4,000 offices contracted as either Gold or Silver membership as soon as possible, as the platform for further member recruitment in the last few months before launch.”

Springett said that Agents’ Mutual is now recruiting at “well over 100 offices” per week, and that more than 4,000 firms have registered their interest but have yet to join.

He said: “We are now working to meet them all and communicate our proposition.

“Momentum is building as agents increasingly recognise the strategic benefits of owning and controlling Agents’ Mutual.

“It is a business which can break once and for all the duopoly of the two big portal groups and can support and defend the market position of full-service, office-based estate and lettings agency.”

He added: “We are now more than 75% of the way to our next major milestone and have every confidence that we shall meet our target number of agent offices for our portal launch in January 2015.”
