An online agent has prompted a backlash from high street firms after claiming sellers are wasting million of pounds by not haggling on fees.

A poll by Housesimple of more than 1,000 sellers claims that 82% agreed the first fee offered to them, with 55% paying at least 1% and a quarter agreeing to between 1.4% and 2%.

Four in ten were unaware that they could have negotiated their commission fee, said Housesimple, with 29% wishing they had negotiated a lower rate after they had agreed it.

Sam Mitchell, chief executive of Housesimple, said sellers could potentially be saving millions of pounds every year in fees if they were prepared to negotiate with their agent. For example, he said, haggling a 1.25% fee down to 1% would equate to a saving of £1,500 on a property on the market for £500,000.

He said: “The survey highlights how much home sellers could potentially save by negotiating and not taking no for an answer.

“There is always room for manoeuvre on the fee and an estate agent that is not willing to reduce their rate will need to have a very strong case as to why, particularly if it is significantly higher than other agents are quoting in the area.

“Unfortunately, for many people, they don’t feel comfortable haggling, and estate agents are extremely good sales people who can put forward a convincing argument as to why they are worth the commission they are charging.

“But at the end of the day they also want to secure your business, and if they are as good as they say they are, then your house shouldn’t be on the market for long, and they will have had to do very little work to make their commission.

“High street agents are living in the past, charging exorbitant fees and not doing enough to justify their meaty commissions. Consumers want value for money, and are, quite rightly, asking ‘why am I paying an agent thousands of pounds for listing a property on Rightmove and managing a few viewings?’”

However, EYE asked some high street firms what they thought about the claims.

Mark Rowe, of RPS Estate and Letting Agents, said Housesimple should concentrate on its own business rather than highlight others.

He told EYE: “Housesimple’s fee is also lower than most, so what’s the worry? Why the need to force home the narrative of high street agents charging too much?

“Sellers have the choice and they make their choices on the different service offerings. What should be highlighted is the cost to a seller of using an inexperienced, out of area, ‘whack it on the internet’ agent, in terms of their achieved sale price.”

Paul Cooney, sales director for Chiswick agent Horton and Garton, said:  “I don’t engage in ‘fee wars’ with other Chiswick agents as I’m secure in the value of my service.

“Every property and every seller is different. I assess each valuation on a case by case basis and allow for flexibility depending on various factors such as the client’s expectations, the valuation and the saleability of the property in question.

“I do have a threshold that I will not cross when it comes to fees, and sticking to my guns cost me a listing last week. I told the vendor to come back to me in a few months when they’d been jaded by the process of working with my competitor. I would never close the door in frustration on a potential client.”

Ken Hume, of James Alexander, said: “Most agents will negotiate their fees, but bear in mind you are asking a company to obtain the best price for your home and that means you should expect that they are good at negotiating their own fees

“If they crumble easily on their fee, how easily might they crumble on your asking price?

“The best agents will be charging more.

“Of course, sellers want the best possible deal and that’s right and proper, but the best agents can obtain higher fees than the worst, so do negotiate but bear the above in mind.

“We structure our fees according to how much work is required to sell the home, so a keenly priced popular area will be at a lower fee.”
