Analysts UBS have downgraded Zoopla to ‘neutral’ from a ‘buy’ position, citing competitive pressures from OnTheMarket.

It said Zoopla “continues to show no sign of a significant recovery in agents”.

UBS has left its ‘buy’ rating of Rightmove unchanged.

UBS said its Evidence Lab research team had found data indicating that OTM has continued its momentum into 2016.

While UBS said it maintained its view that “OTM is unlikely to be a major long-term player”, it said that there were still risks for Zoopla, which had been more impacted by OTM than Rightmove.

It said that Rightmove’s market-leading position remains strong.

It added: “Overall, we see the launch of OTM as having actually strengthened the position of Rightmove by making it a stronger number one in the segment, with Rightmove now having circa 65% more properties listed for resale than Zoopla.”

Despite the downgrade, UBS raised its share price target for Zoopla from 250p from 260p.

Separately, an analyst at Credit Suisse has raised with investors the issue of OTM chasing up payment and seeking to enforce its contracts with some agents through the sending of legal letters.

As reported yesterday, OTM has used a law firm to send the letters.

Joseph Barnet-Lamb, of Credit Suisse, has said in a note to investors: “We believe it can be argued that agents have cause to leave OTM with OTM debatably not having delivered the service they promised to agents.”

He says that most agents would not have the financial fire power to mount a legal challenge to OTM but “should the agent win such  case we believe it could open the floodgates for other agents potentially leaving OTM”.

Yesterday, a spokesperson for OTM declined to say how many legal letters – from top law firm Eversheds – had been sent out, or whether it was the first time that such letters had been sent.

However, it is understood that OTM regard the matter as no more than normal credit control. OTM has also never made a secret of its determination to enforce its ‘one other portal’ rule.

Russell Quirk of eMoov, which as an online agent is banned from using OTM, yesterday said the situation was a “farce” with agents effectively suing one another.

He said: “Worse still, one of the Agents’ Mutual board members is the chairman [sic] of the NAEA who is effectively now suing dozens of his own members.”

He added: “From those agents we know who have received these letters, they will not be bullied by Savills and co to pay for something that doesn’t work, that they don’t want, that prevents them from serving their customers best and they are ready to challenge Agents’ Mutual’s legal threats.”

OTM declined to comment on Quirk’s claims.
