A six-branch firm, Andrew Milsom Estate Agents in Buckinghamshire and Berkshire, has joined OnTheMarket.
The firm will now be listing on OTM and Rightmove, after removing its properties from Zoopla.
Andrew Milsom, director, said: “We have been impressed with how quickly OTM has established itself, and we think the website is a refreshing change for the consumer because it focuses entirely on the property listings.”
Helen Whiteley, commercial director of OTM, said: “It’s exciting to see yet another long-established, high-quality, multi-branch firm such as Andrew Milsom deciding to join us.
“It strengthens our market position in the Thames Valley and Chiltern Hills area and we are looking forward to working closely with Andrew and his team.”
OTM announced in May that overall support for the portal had reached in excess of 7,000 UK estate and letting agent offices. This figure includes offices which are contracted and those which are covered by Letters of Intent to join Agents’ Mutual and to list on OTM when overall support exceeds 7,500 offices.
