An estate agent has expressed his concern after discovering that ten of his properties are appearing on a site that he knew nothing about.

Eight of the properties found on NetMovers are out of date, having either been sold or withdrawn.

The other two properties show incorrect information.

Peter Hughes, of Country Property in Petworth, West Sussex, said: “This website does not have any authority from us to post any information.”

NetMovers started off as a private for sale by owner website, before relaunching as an online estate agent, later becoming a portal.

However, it appears to be highly controversial, with some prospective tenants complaining over the course of 2011 to 2013 online that NetMovers tried to charge them for viewings.

There are some damning reviews here

Hughes only discovered that the properties were listed on the site when his firm received an inquiry about a property which was withdrawn last October.

He said he had emailed the website asking them to take down all the properties immediately, but has received no reply.

He said his concerns were that any scraped properties rapidly go out of date, copyright issues, and that it is unclear whose legal responsibility it is for such a listing.

Other agents whose properties appear on the NetMovers site include Knight Frank – which could be among those inadvertently breaking OnTheMarket’s “one other portal” rule – and Davis Tate, part of LSL.

For example, Knight Frank’s Guildford office has 16 pictures of a £5m house in Farnham on NetMovers.

Independent agent Andrew Lodge has 11 photos and details about a £2.7m house, also in Farnham, on the site.

On its website, Lancashire-based NetMovers describes itself as “one of the UK’s leading property portals”.

While it apparently scrapes properties, its terms of use state: “You may not download or pass off any material from this website without our written consent.

“Properties available on this website are provided to us by estate agents (estate agents, letting agents, commercial agents and overseas agents) for your information only. We cannot verify these details and therefore make no warranties or representations as to their accuracy or completeness. If you rely on these details, you do so at your own risk.”

The site also declares that “all advertising is pre-paid” and that advertisers grant to NetMovers a licence to display listings.

Eye was yesterday unable to contact NetMovers to give them a right of reply, although we tried by both phone and email.
