How much longer can traditional estate agents and letting agents survive, asks Guardian journalist Patrick Collinson – who seems to think the answer is “not very long at all”.

In a provocative blog, the paper’s money editor says that letting agents charge “extraordinary fees” – but that both sales and lettings agents will “go the same way as Blockbuster, HMV and Lunn Poly – business models blown apart by the internet”.

He says that until now, online agents have had “lamentably little impact”and that most sellers still hire a traditional estate agent and the vast majority of tenants have little choice but to go through a letting agency and pay “often exorbitant fees”.

Collinson confidently predicts: “But in 2015 that will change. Already, star fund manager Neil Woodford has pumped £7m into PurpleBricks.com, while easyProperty.com, the latest venture from Sir Stelios Haji-Ioannou, has raised £10m and begins its assault on the lettings market early next year.

“Emoov is expected to reveal in the next few weeks its new financial plans, while uPad is planning a multi-million pound advertising blitz.

“If you are selling your home, or are a landlord trying to find a tenant, you have almost certainly not heard of any of these players – but next year you won’t be able to miss them.

“Last month the marketing boss of Confused.com was taken on by PurpleBricks, and industry observers are likening it to the moment when the price comparison sites wiped out the traditional insurance broker.”

Collinson argues: “But will the online agents, even if stuffed with cash for advertising, really dislodge the incumbents, as much as we like to hate them? On a straightforward comparison of costs, there is no case to answer.

“PurpleBricks has a flat fee of £798, while Emoov’s full service is £658.50. For lettings, OpenRent charges landlords £49 to find a tenant, easyProperty £59.99 and uPad £118.80, although these are for the basic service. To manage a rental, easyProperty will charge 3% of the rent.”

Collinson concludes: “Crucially, what all these online services have gained is access to Rightmove and Zoopla.”

* Separately, the City press is buzzing with speculation after two of star fund manager Neil Woodford’s key executives left without explanation. Their departures come less than a year since Woodford launched his investment company. Chief operating officer Nick Hamilton and chief legal and compliance officer Gray Smith resigned from Woodford Investment Management last Tuesday.
