The Financial Services Authority (FSA) has outlined new guidelines that effectively outlaw commission payments, which have been seen by many consumers as a way of getting "free" advice.
The FSA has made it clear that it is concerned that these payments are used to disguise the cost of financial products, and may create bias in an adviser's recommendations.
A spokesman for the FSA said it hoped its proposals would restore consumers' trust in the financial services industry at a time when many "need real help and advice with their retirement and savings planning". The changes are due to come into force in 2012.
The regulator's review contains three key proposals. Probably the biggest change is to the way advisers are remunerated.
For the first time all advisers, whether they are independent financial advisers or sales agents, will have to declare and agree with the customer in advance exactly what the advice costs. Consumers will then have the option of paying for it in advance or opting for the cost to be taken from their savings over a period of time.
A spokesman for the FSA said: "Commission as we know it will disappear for ever. We want to sever the providers' involvement with the advisers' fees." The FSA has not ruled out banning commission completely at a later date.
Another major change is that all advisers will now have to take advanced qualifications, equivalent to the first year of a degree course, if they are offering full advice to consumers. At present 80pc of advisers do not have these qualifications.
Andrew Fisher, the chief executive of Towry Law, a firm of financial advisers, said: "This is brilliant news for consumers. The smoke and mirrors, lies and obfuscation that have been used to disguise consumer fees will be stopped.
"Individuals thought that commission meant 'free' advice but it was always paid for, either by raising product charges or by reducing the value of a consumer's investment. For the first time, any commission charge will now explicitly be linked to consumers' savings and will have to be agreed upfront."
The FSA said its framework would provide a mix of services, so "less sophisticated" investors who could not afford to pay for full advice were not excluded. Many companies are expected to offer "guided sales", where consumers are given basic financial information.
If this led to a recommendation to buy a certain product, however, the sales person would still be required to have the appropriate professional qualifications and be upfront about any product charges. The FSA said: "It must always be made clear at the outset whether consumers are paying for independent advice or a sales service."
Trevor Matthews, the president of the Chartered Insurance Institute said these proposals should "kick-start" the process "of moving to higher levels of competence and and professionalism". He added: "The biggest challenge for the long term future of this industry is to restore trust in financial services, which has been dented for too long." He said today's proposals go some way to addressing this issue.
David Elms, the chief executive of IFA Promotion, said he welcomed the proposals but was awaiting details on how they would be implemented.
He added: "We want to see the same standards applied to all advisers, whether they are recommending products from across the spectrum of providers or selling just one company's products.
"This should enable consumers to understand the choices available to them."
