A firm with 37 branches has joined OnTheMarket, it was revealed last night.

Nottingham Estate Agency and Harrison Murray, both part of the Nottingham Building Society, said they were “proud to announce their membership of OnTheMarket”.

They will now be advertising all their sales and rental properties on OTM and Rightmove.

The businesses are independent agents with over 25 years’ experience as estate agents, and have offices in nine counties.

Last week, OTM announced that the level of overall support for the portal had risen beyond 6,500 estate and letting agent offices.

That figure consists of already contracted offices plus agents who have signed a Letter of Intent to join OTM when total support reaches 7,500 offices.

Sue Snaith, head of estate agency at the Nottingham Estate Agency and Harrison Murray, said: “The achievements of OTM over the last year have been impressive.

“It is already established as a major portal and the website has been beautifully designed to give consumers a pleasurable search experience.

“It is a great place to showcase our clients’ properties.”

She added: “We believe OTM will continue to prosper as more agents come to realise that by joining this 100% agent-owned and agent-controlled portal, this represents the best opportunity to regain control of their precious property data.”

OTM chief executive Ian Springett said: “We look forward to welcoming many more new members throughout 2016 as our momentum continues to build.”

It is thought that Nottingham Estate Agency and Harrison Murray businesses pulled off Zoopla some while ago, meaning they listed on Rightmove.  If so, the decision to list additionally on OTM could be a pointer in the evolving property portals story.
