Chestertons, one of the founding agents of property portal OnTheMarket (OTM) and one of London’s largest branch networks, has returned to Zoopla after a three-year hiatus.

Its 32 branches have started listing on ZPG’s two websites with immediate effect as well as continuing to appear on Rightmove and OTM.

A spokesperson from OnTheMarket said: “”Chestertons remains a valued and supportive estate agent customer of, and shareholder in, OnTheMarket and indeed has recently chosen to sign a new 5-year listing agreement with us.”

Chestertons is one of a growing number of agents now listing on all three platforms after OTM lifted its ‘one other portal rule’ following its listing on the AIM stock market.

“We’re excited to be returning to ZPG and having all of Chestertons properties listed on all four of the UK’s main property websites, which will benefit both our customers and our business,” says Allan Collins, CEO of Chestertons.

The company, which founded OTM alongside several other high-profile agents including Knight Frank and Savills, is not the only agent to have signed up with or returned to ZPG recently.

The portal says a flurry of branches have signed a listings agreement with it in recent weeks including eight from Martin & Co, six from Winkworth, five from Surrey agent Warren Powell Richards, five from Hampshire agent Charters and three from Ellis & Co.

“We are very pleased to welcome Chestertons and many other partners back to the ZPG platform,” says ZPG MD of Property Mark Goddard (left).

“They recognise the value we can bring to their business in terms of brand exposure and to their vendors and landlords by ensuring the maximum enquiries for their properties.”

Chestertons was founded in 1805 and became one of London’s leading agents before going into receivership in 2005 and then being bought by the current shareholders who then began building it back up from eleven branches to its current 32, led by now former boss Robert Bartlett.
