Adviser brands Scottish Life, Scottish Provident, Bright Grey and Royal London Asset Management will come under the Royal London name over the next 18 months.
Phil Loney, group chief executive officer of Royal London, said: “The move to a single brand emphasises the scale and reach of Royal London across the investment, pension and protection markets, and seeks to make the benefits of our mutual approach tangible for all of our customers.”
The advertising campaign, which also includes digital outdoor and press advertising, will go live on May 2.
The provider is also launching a direct to consumer business for customers who do not use financial advisers.
Loney added: “We are going further so next week we launch a new way to buy insurance products from Royal London via our direct to consumer business.
“Royal London’s insurance business has grown through a single-minded commitment to distribution through financial advisers.
“This remains our primary focus but we recognise that there are a number of sections of the population who will never turn to a financial advisor. “
Royal London, which dates back to 1861, has 5.3 million customers and half a million members.
