The bank was created in 2011 following the acquisition of the former Kent Reliance Building Society by J.C. Flowers.
The bank hopes to raise £41m by selling shares.
The group also operates niche lenders Interbay, Prestige and Heritable in the UK plus Jersey Home Loans and Guernsey Home Loans in the Channel Islands
The group’s brands offer residential mortgages including bespoke first charge mortgages, second charge mortgages and shared ownership mortgages with buy‐to-let and commercial loans also available.
This follows the announcement by Lloyds Banking Group over its plans to float TSB this summer.
Andy Golding, chief executive of OneSavings Bank, said: “We have made enormous progress since the bank was created three years ago thanks to the support of our shareholders and the hard work of all our dedicated staff.
“In 2013 we improved our underlying profitability very significantly by
attracting more savers and borrowers and keeping costs under tight control. We have a deep understanding of our markets and are confident we can continue to grow using our specialist, flexible and personal approach to lending and saving.
“A stock exchange listing is the next natural step in the evolution of the business, providing us with access to the capital markets to enable us to invest for future growth.”
