Navigator Research has been re-badged Aviva Research.
Globally, Aviva is the fifth largest insurance group with more than 30 million customers.
The investment research service will build on the Aviva name and reputation but continue as normal, according to Aviva research manager Stuart Fechner.
"This research team has a strong reputation and long history in providing fund and investment research for over 20 years within the Aviva Group," said Fechner.
"Financial advisers using Aviva Research will continue to access world class information from an expert team of researchers."
The team reviews fund and fund managers and compiles monthly fund rating reports.
The service also provides information on investor asset allocation profiles, suggested fund blends or model portfolios, monthly economic market updates and other topical investment updates.
