LONDON, Oct 15 (Reuters) - Credit-checking firm Experian (EXPN.L) cancelled the mooted sale of its online price comparison business, Pricegrabber, causing Experian's shares to fall sharply.

In a trading update, in which the company reported a 13 percent rise in revenue in the first half of its financial year, Experian said it had decided not to sell the unit.

Experian said potential buyers were unable to finance acceptable offers in current market conditions.

The about-turn came eight months after the company put Pricegrabber on the market. Experian, best known for running consumer credit checks for banks and other lenders, paid almost $500m for the price comparison website in 2005.

"We received many expressions of interest, but given the financing environment, these did not convert into bankable transactions," Experian Chief Executive Don Roberts told reporters on a conference call.

By 0912 GMT, Experian shares were down 7.27 percent at 306 pence, while the FTSE 100 share index was 3.1 percent lower.

Seymour Pierce analyst Kevin Lapwood said: "People were expecting a bit more on the Pricegrabber side. They were expecting them to sell it on."

Experian also said its revenue for the six months to Sept 30 rose 13 percent, with acquisitions helping to offset flat revenue growth at the core credit services division, which was held back by a slowdown in lending as banks grappled with the credit crunch.

Experian's Roberts told reporters the company was repositioning itself as its banking customers increasingly prioritised debt collection.

"The short-term outlook is less clear than it's been at any time in the last 12 months. While the environment is tough, it's true to say that there are significant opportunities for Experian," he said.

Roberts added that he was hopeful bank rescue plans launched over the past week by the U.S. and UK governments would help boost retail credit volumes.

"Anything that helps stabilise the banking environment will benefit Experian. We want to see healthy, well-capitalised clients and a free flow of credit," he said.

Experian also said it had agreed to sell its French credit card processing and outsourcing businesses for 203 million euros. The disposals will generate net proceeds of 150 million euros, which will be used to pay down debt, the company said.
