Most consumers will "shop around" for the lowest adviser charge in the post RDR world, research suggests.
According to an NMG poll of 324 investors who have used an IFA, 67% will compare charges before selecting an adviser.
Meanwhile, 69% agree the adviser charge will improve their understanding of the cost of advice, although 37% say they may choose to purchase their investments without seeking guidance.
From 1 January 2013, adviser firms can only be paid through charges it has set out and agreed upfront with their clients, rather than via commissions set by product providers.
The FSA has made clear it is up to firms how they charge for their services, whether via fixed fee, hourly rate or percentage of investment.
It says separate charges for any initial discursive work and for occasions when clients decide against a recommendation or cancel a product within its cooling-off period must also be product-neutral.
NMG director Jonathan Gunby says: "Our investor research is broadly encouraging, with good levels of support from clients for the adviser charge and overall we don't expect many investors will be driven to change their current arrangements.
"However, there are clearly some concerns and advisers must not take their existing relationships for granted. The industry needs to better understand and prepare for the segment of clients that think they can go it alone rather than pay a charge for advice".
The study also suggests the vast majority of consumers back the industry's move to higher minimum qualifications.
NMG says the combination of the adviser charge and higher levels of qualifications mean a quarter of all respondents surveyed say that they are more likely to use an adviser in the future.
