The old website addresses for MGM Advantage and Stonehaven have begun redirecting to the new website, which has gone live today. Stonehaven, an equity release firm, was acquired by MGM Advantage in January 2014.
Officials said they were gearing up for the launch of a new product called The Retirement Account – later in the year.
In a statement they said: "By bringing the two brands together, Retirement Advantage is better positioned to meet adviser and client needs throughout retirement."
Chris Evans, chief executive of Retirement Advantage, said: "With greater numbers of people including their property as a means to fund retirement aspirations, and advisers adopting a holistic view of planning, drawing on all assets to fund financially demanding retirements, the combining of equity release (Stonehaven) and retirement income (MGM) specialisms makes eminent sense.
"We are already innovating. In the past two months, we have launched money-back guaranteed annuities, which effectively addressed one of the main criticisms of annuities. We have also introduced a whole raft of new equity release features, including free valuations, flexible drawdown and higher LTVs."
The company has launched the brand alongside the strapline 'feel better equipped'.
Mr Evans said: "We have witnessed significant change in the market over the past year, and the dust has only just begun to settle.
"Expectations of retirement providers are rightly sky-high, and we want to meet these expectations by providing a broad and competitive retirement product range attractive to all retirees.
"That could be competitive annuities for anyone looking for a guarantee lifetime income, or innovative equity release products and features for people seeking to unlock cash from their property."
On the plans for the Retirement Account, he added: "We are taking our time to develop and deliver something to market which is very different to anything available today."
