The portal Lettingweb has converted itself into what has been described as a ‘commutual’ – a cross between a commercial organisation and a mutual.

The Scottish website is offering letting agents a 50% share of its business and is consulting on whether to adopt a strict ‘one other portal’ rule.

Lettingweb, which last week announced its merger with membership organisation LetScotland, is currently on a three-day equity roadshow covering Edinburgh, Glasgow and Aberdeen, telling agents of its new offering.

The ‘one other portal’ rule would allow agents to list on Zoopla as well as Lettingweb – as the two are parters – leaving agents to choose another Scottish portal, or the likes of  Rightmove.

However, a complication could be that a number of top agents in Scotland have already signed up as Gold members of Agents’ Mutual, which will enforce a strict only one other portal rule.

In 2012, Zoopla partnered exclusively with Lettingweb – meaning that any Scottish letting agent uploading properties to Lettingweb also has their properties listed on Zoopla.

The tie-up means that Lettingweb is effectively Zoopla’s letting arm in Scotland.

Lettingweb said that the first two roadshows had been exceptionally well attended, with the third taking place tonight.

CEO Alex Watts said of the “mutualisation” proposal: “It is a once in a lifetime opportunity for letting agents to take control over their own destiny.”

He said a threat to the lettings industry in Scotland was an “aggressive online publisher” seeking to achieve monopoly status in the Scottish market and dictate marketing prices and terms to agents.

He cited another threat as a “damaging external environment, with ill-considered legislation and a hostile media leading to a distorted view of letting agents and the private rented sector”.

Thomas Ashdown, of Lettingweb competitor Citylets, said: “Citylets commends any initiative that purports to be for the good of the industry.

“It is not our intention to comment on the merits of this hydrid model or proposition at this time but would however say that standing independent from Zoopla would likely be deemed helpful now by Scottish letting agents and, if this ‘aggressive online publisher’ referred to is Rightmove, would ask: is Zoopla any different?”
