Advisers have been warned customers may drift away from them and question the value of their service if they use just one platform.
Aviva research published today suggests 23.3% of advisers regularly use only one platform, while 14.5% are registered for just one.
At a roundtable event this morning to discuss the research, Andy Watts (pictured), intermediary sales director at Avelo, said single platform use could damage advisory businesses.
"The adviser needs to be presenting their business and the quality of service they provide to the client in order to retain them.
"If they became lazy and pointed them to a single platform environment, over time the consumer will say "what are you doing for me?" and cut them out of the equation," he said.
However, Danny Cox, head of advice at Hargreaves Lansdown, which provides its services through its own Vantage platform, said single platform use may be appropriate for some clients.
"You need to understand what the client wants and deliver the service they are asking for," he explained. "What the ultimate solution is, that's not a joined up issue."
"Just because [an adviser] is using one particular platform, as long as it is suitable, we do not need to be worrying about it."
Meanwhile, of the 249 advisers who responded to the survey, 22.9% said they were registered for five or more platforms, although only 5.6% actually regularly used as many.
In its recent platform policy paper, the FSA suggested the use of a single platform would most likely not meet the requirements of providing independent, whole-of-market advice.
