Online estate agent HouseSimple has launched a No Sale, No Fee payment plan, saying that consumers are uncertain about paying money upfront.

The new package costs up to £995 and replaces a pay-as-you-go option launched in July last year and which charged £9 a week plus a success fee of £495 if the property sold.

The £995 fee can be reduced. If the seller uses conveyancing and mortgage broking services offered through HouseSimple, the fee falls to £795. If the seller uses only one of the services, the fee is £895.

HouseSimple is the online agent of choice for Carphone Warehouse founder Sir Charles Dunstone who, together with business partner Roger Taylor, has invested £5m.

The new payment plan will be offered alongside the current £395 fixed fee option, where the fee is payable on completion of the sale or after 12 months, whichever happens first. With the fixed fee option, there is a discount of 10% if the seller pays it upfront.

HouseSimple continues to offer a free week’s trial for new customers.

CEO Alex Gosling said: “We have introduced the No Sale, No Fee model because we recognise this is a fee structure that the British public are familiar and comfortable with.

“In particular, for people who have never sold a property online before, there is always likely to be a degree of uncertainty about paying upfront.

“It’s understandable for them to think, if I pay my money upfront, how committed will they be to selling my house?

“We wanted to address that concern and make the service more accessible to all, because we are confident once someone uses us to sell their property, they won’t use a traditional estate agent again.

“Online estate agency is the future of this industry. Not only do we offer an equivalent service to the high street agent for a fraction of the cost, but we also secure more sales than high street estate agents and achieve a higher asking price on sales.”

To date, HouseSimple claims to have sold or let £1bn worth of property, saving UK home owners a total of £20m in fees, and on average £5,247 per house sale.

HouseSimple claims to be the UK’s second largest online estate agents by number of monthly property listings.
