Concern is mounting among OnTheMarket agents about Houser, the new portal which is due to launch today – taking its properties direct from agents’ own websites without their authorisation.

According to one agent, posting on Eye, this could breach the “one other portal” requirement.

The agent said this was the response they had received from OTM after querying it: “Your contract with Agents’ Mutual does indeed mean that you may only advertise with one other property portal, which includes aggregators such as Houser.

“We of course understand that these websites scrape data, often without your go-ahead, and as such request that you contact them and ask them to cease scraping and to remove your listings as soon as possible, but as this is out of your direct control we will of course bear with you while you wait for Houser to action your request.”

Eye asked Ian Springett, chief executive of Agents’ Mutual, which launches OTM in just two weeks’ time, for further information.

He said yesterday: “We have not yet sent out formal guidance to all our member agents so this response may have been sent by one of our staff on an ad hoc basis.

“However, it does broadly reflect the policy we will be adopting.

“Spicerhaart Group is leading the way on this.

“Houser emailed all their offices and then accessed the Group’s websites and began displaying their information on the Houser website without authorisation.

“Spicerhaart immediately contacted Houser to require them to remove that information from their website and received on Friday an immediate response confirming that this would be done.

“We will shortly be asking all our members to take the same action.

“The response to Spicerhaart indicates that Houser will take ‘up to 10 days’ to remove their information.

“It is not clear why it should take so long.

“We know from feedback other members have given us that they are very concerned and angry that someone would access and use their data without their consent.”

The picture is of Houser’s official press launch last Thursday at the Hilton in London.

At the event, Houser founder Rocky Mirza told journalists: “Houser means business.”

He claimed that charging estate agents to list their properties “is a broken business model and is not in the best interest of the consumers”.

He emphasised that Houser’s goal is to create the largest inventory of listings. These will include private listings.
