Royal London is scrapping the Scottish Life, Bright Grey and Scottish Provident brands to move to a single "master brand" for its UK life, pensions and investment businesses.
Over the next two years the group will move its main UK insurance businesses under a new "visual and verbal expression" of the Royal London brand to be unveiled before the end of this year.
Royal London's financial education service Moneyvista will also move to operating under the Royal London name.
The Ascentric wrap platform will retain its name as it offers an independent wrap solution for advisers.
In the Republic of Ireland Royal London will continue to operate under the Caledonian Life brand.
Commenting on the move group chief executive Phil Loney said: "It is a key part of our strategy that Royal London will operate under a single brand across our UK pension, protection and asset management businesses.
"The transition will be phased in gradually over the next two years so that we can take customers with us on this journey. During this time our customers and their advisers will increasingly become familiar with the new Royal London brand.
"By moving to a single brand we can emphasise the scale and reach of Royal London across the investment, pension and protection markets, and seek to make the benefits of our mutual approach tangible for all of our customers."
Loney said the move "does not mean a change in our focus", and that Royal London remains "fully committed" to supporting advisers.
"It does mean that the Royal London name will become far more visible and people will come to recognise it as the leading mutual provider - a key differentiator from our competitors.
"Many of our pension customers are already members of Royal London and we aim to make the benefits of membership an increasingly prominent part of our proposition going forwards."
