Property guru Sarah Beeny claimed on national television yesterday that all online agents belong to a body which she named as the National Federation of Estate Agents.

Beeny was appearing on ITV’s This Morning programme, and was asked by presenter Amanda Holden if online agents had to be regulated.

Beeny replied an emphatic: “Yes.”

She said “all online estate agents” had to belong to the “National Federation of Estate Agents – they have to do that, and they have to verify properties”.

She said that this allowed them to feed into property portals.

Beeny, who runs an online agent called Tepilo, was on the programme to plug her show about people selling through online agents.

Beeny said “really good high street agents” were not concerned about online agents, but that “quite a lot aren’t very amused by it”.

On a busy day for the airwaves about online agents yesterday, two vendors who sold their homes without high street agents told their stories on Radio 4’s You and Yours programme.

One, in Cornwall, sold her bungalow for £245,000 using private sale-by-owner site The Little House Company.

She said she had saved about £7,000, and while it had taken longer than she had anticipated, she would do it again.

She did, however, warn that to be successful, sellers needed to view their house as a commodity, and not be afraid to ask searching questions of would-be purchasers, including whether they had funds.

A second seller used Housesimple, an online agent, to sell her home in Cheshire for £745,000.

She said she had invited some local agents to her home to check that the valuation was right. She had then written the narrative and her husband took the pictures.

She said that as a purchaser, she never went into agents, but only ever visited Rightmove.

She said she just needed an agent to facilitate the property going on Rightmove “and I could do the rest”.

Property commentator Kate Faulkner spoke of the power of the two big property portals, saying they had been set up in the first place because of the monopoly of local newspapers, although they had now become something of a monopoly themselves.

She said that a private seller was at a disadvantage through not being able to use them.

But Faulkner also said that marketing a property was the “relatively easy bit” and that where agents scored was in their ability to hold a chain together.

Beeny’s Sell Your Home series starts on Monday on C4.

She has said it won’t feature her own online estate agency, but she did tweet out: “All about saving thousands by using online estate agent like my @tepilo xx”
