A total of 23% feel that the state of the economy is positively affecting their business, compared to 15% in June.
Researchers also found that advisers feel there is a growing sense of political stability.
As the coalition government reaches its sixth month in office, only 16% of intermediaries believe that the new political agenda is a significant business concern compared to 22% in June.
Greater confidence in the macro economic climate has encouraged intermediaries to focus on their own businesses by looking to increase profitability, 26%, and develop their business models, 18%.
Indeed, 42% of advisers believe their revenue will increase over the next three months.
With more effective technology cited by one in five advisers as increasing business profitability, a growing number are looking towards platform adoption, 7% compared to 3% in June, and 10% are planning on installing new technology.
With their future business success in mind, generating new client leads is one of the most important things on the intermediary agenda for the next three months, 35%.
In line with the research carried out in June, advisers still think personal relationships are key.
A total of 86% still found referrals from existing clients the best way to generate new business.
But an increasing number, 42% compared to 18% in June, say they also relied on referrals from other professional advisers such as accountants and solicitors.
The number of advisers who said the size of their business will either remain the same size, or will expand or diversify is high at 86%.
Simon Badley, director of intermediary at Aviva, says: “After a period of significant instability, it is encouraging to learn that advisers are feeling more confident about the economic and political climate.
“The fact that a growing number of advisers are actively looking to develop their business models shows the extent to which the industry is looking to the future.
“It is also interesting to note the increasing number of advisers looking to adopt technology to drive business profitability.”
