City companies with rejected customer complaints will receive a rebate of 25% or more, but billing management companies will be charged to bring cases to the Finance Ombudsman Service for the first time.
The dispute agency has said that, under a complaint brought by a claims management company or professional representative, “If unsupported or withdrawn, the financial business on which the complaint was made will be subject to a reduction fee of £475. They say they'll pay, in exchange for £650.” 
The Ombudsman adds that it will begin claiming a claim management company that will file a complaint on behalf of its client for the first time.
The companies that became famous during the payment protection insurance scandal say they can bring 10 cases to their services for free per year.
But then they will be charged £250 per case starting in April. They receive a £175 rebate “if the outcome is in the consumer's favor.”
The Financial Ombudsman Service stated: “The move aims to make our funding arrangements more equitable and encourage professional representatives to file more serious complaints.
He adds that the company claims that between April and December last year, businesses are behind in about 47% of cases dealt with.

The move will be replaced by interim ombudsman James Dipple Johnstone a day after the Financial Ombudsman Service unexpectedly replaced CEO Abby Thomas.
Dipple-Johnstone said: “There have been more cases brought about by professional representatives, but few of these cases lead to better results for clients.
“Currently there is little commercial incentive to ensure that there are sufficient complaints brought by representatives or benefits.
“As a non-profit service, we can spend finite resources handling thousands of withdrawal or abandoned cases, which can lead to increased latency for other customers.”
Director of the Finance & Lease Association, Director Stephen Haddrill welcomes the move, but added that the proposed fees charged to the billing management company should be higher.
Haddrill said: “The introduction of charging is the most important step. Claims management companies are the leading companies that should not be free to ride, especially as they have driven a compensation culture that undermines investors' trust in the UK and threatens growth.
“However, today's decisions regarding the level of claims are insufficient and we ask for continued increase.
He adds: “Professional representatives should be prosecuted on the same standards as lender companies to provide a fair and impartial approach, and the Financial Ombudsman Service, in which lenders apply the “polluter payment” principle. The proposal that lenders must pay the majority of the case fee, even if they are not against their objectives.
“I don't know of any other examples of cases where there are fewer losers in cases in which two companies are involved than the winners.”
The conflict institutions add that cases brought about by individuals, charities and voluntary organizations remain free.
