* Fees won't be charged on ongoing basis, only when service delivered
* Move comes after ASIC order
* Powerful inquiry releases report on Australia's financial sector (Adds bank's statement, estimated impact of changes, executive comment)
SYDNEY, Feb 4 (Reuters) - Commonwealth Bank of Australia's CBA.AX financial planning unit is stopping levying service fees continuously to its customers and will only charge fees when the services are delivered, following an order from the corporate watchdog.
Commonwealth Financial Planning Ltd (CFPL) has started the process to stop levying such service fees to existing customers from Feb. 1, Australia's top lender said in a statement on Monday.
Earlier in the day, The Australian Securities and Investment Commission (ASIC), in a separate statement, told CFPL to stop taking fees because it has failed to comply with a court order to fix wrongly levied fees.
The lender said that CFPL has also agreed not to enter into any new service arrangements with customers.
CBA expects the changes to have an impact of A$40 million on CFPL's pre-tax profit.
"CFP will be moving to a new financial advice fee model where customers will pay for advice services when they are delivered," Commonwealth Bank Group Executive for Retail Banking Services, Angus Sullivan, said.
The orders come as the final report is released by a powerful inquiry that exposed last year systemic wrongdoing across Australia's financial sector. Bank, which came under fire at the inquiry over its fee structure and for charging customers fees for financial advice they never received, is seen as particularly exposed to a regulatory crackdown owing to the size of its retail business. said the bank's financial planning arm failed to respond adequately to its concerns about its fees for no service, triggering the restrictions. bank had no immediate comment when contacted by Reuters.
The "Big Four" banks - CBA, Westpac Banking Corp WBC.AX , Australia and New Zealand Banking Group ANZ.AX and National Australia Bank NAB.AX - plus AMP AMP.AX have already committed to pay more than A$2 billion ($1.45 billion) to wronged customers.
The new requirements would continue until CFPL is able to satisfy ASIC that all the outstanding issues have been remedied.
"ASIC has also been informed by CFPL that it is now in the process of transitioning its ongoing service model to one whereby customers are only charged fees after the relevant services have been provided," the statement said. "ASIC will monitor CFPL's transition to the new model."
