Zoopla has announced that ten branches of leading London agent Kinleigh Folkard & Hayward have returned to it this week for an initial 12-month trial.

It has hinted that it could drop Rightmove if the trial goes well.

KFH has some 60 branches in total and left Zoopla just before the launch of OnTheMarket.

The branches now back on Zoopla are Fulham, Bayswater, Clerkenwell, Earls Court, Chelsea, Holland Park, Marylebone, South Kensington, St John’s Wood and Brook Green.

In recent months, a number of agents have gone back to Zoopla, following the dropping by OnTheMarket of the ‘one other portal’ rule.

Returners include branches of Carter Jonas, Strutt & Parker, and Humberts.

Zoopla claims to be particularly strong in the capital, currently listing more London rental properties than other portals, with almost 45,000 available rental homes.

Zoopla managing director Charlie Bryant said: “We believe that in London particularly we are the only choice for agents, representing the best value for money and offering agents real returns for their businesses.”

Paul Masters, group operations director at KFH, said: “During the trial period, we will be testing their performance against that of Rightmove, which will help us assess which portal we list with next year alongside OnTheMarket.”

In other portal news, newcomers Commercial People and Residential People have jointly secured more than 100,000 property listings in the five weeks since launch.

The listings are from 1,600 agents in the UK, UAE and South Africa. Over 20,000 of the listings are in the UK.

The portals, which offer free listings, are set to launch in India, Nigeria and China by the end of this year.

Both the portals are operated by proptech firm Commercial People.
