OTM signs up UK’s largest landlord in landmark lettings deal
OnTheMarket President, Jason Tebb, announces Grainger will now list its portfolio of more than 11,000 rental properties on his portal.
OnTheMarket has signed up one of the UK’s largest landlords in a new deal, it has been revealed.
Grainger, which claims to be the biggest listed residential landlord in the UK, will now list its portfolio of over 11,000 ‘build to rent’ apartments on OTM.
Major milestone
OTM says the deal “marks a key milestone in the platform’s growth”, and that since it was acquired by CoStar Group in 2023 it has enhanced its tools and market reach, which helped attract Grainger.
Jason Tebb, President at OnTheMarket (main picture), says: “We’re thrilled to welcome Grainger to the platform, their reputation for excellence perfectly aligns with our mission to offer a superior property search experience to the millions of consumers who visit our site every month.”
Expanded reach

And Jonathan Pitt, Director of Lettings & Residential Marketing at Grainger, says: “We are delighted to partner with OnTheMarket as we continue to expand our reach to renters across the UK.
“This collaboration allows us to showcase our portfolio of over 11,000 high-quality rental homes on a platform that shares our commitment to excellence and innovation,” he says.
Sector leader
“The enhanced tools and growing audience that OnTheMarket offers will help us connect more efficiently with renters seeking professionally managed, long-term homes.”
Grainger also describes itself as a leader in the build-to-rent sector, and announced in May “another period of strong performance” for the six months ending in March.
