Number three portal OnTheMarket claims its performance has exceeded expectations in the past two years.

OTM was acquired by the US-based CoStar Group in 2023 despite opposition from those in the industry who wanted it to remain an agent-owned operation.

Since the acquisition by CoStar the portal has been relatively tight lipped about performance.

But this morning it claims to have “almost doubled” sales leads and to have increased website traffic and stock “by as much as 55%.”

It also claims a 55% rise in website visits, with page views increasing 110%.

Its property stock is up by 47%. 

A statement from the portal says: “Engagement with serious property seekers has surged with twice the volume of property alerts sent compared to 2023 and sales lead generation up by 94%.”

It stars that these figures are ahead of target while maintaining a commitment to “fair and sustainable pricing.”

Jason Tebb, the former chief executive of OnTheMarket who took the title of President after the CoStar acquisition, comments: “The strategy was clear from the outset: to implement CoStar Group’s expertise and investment early on to accelerate us toward our goal of becoming the market leading portal in the UK.

“These initial two years have focused on

fortifying the fundamentals that matter most to our customers: mobilising almost £50m of committed investment to build inventory, enhance web traffic and engagement from serious property seekers, and increase quality lead generation.”

He continues: “The results speak for themselves. 

“This significant growth is a clear reflection of the rising confidence in our platform as the trusted destination for property seekers and estate agents.

“The progress we’ve made is only the beginning. 

“With further significant investment in 2026 and beyond, we are more committed than ever to deliver even greater value for our customers, pushing innovation across the platform, and continuing our journey towards becoming the UK’s leading property portal.”
