Prestige will continue to be run by the same team including directors Simon Stern, Howard Sheldon and David Stern.
Simon Stern, director, said: “Prestige will have the ability to offer quality products in a fast growing market.
“We have had positive feedback on our new product offering from key partners and we will announce further details in the forthcoming weeks.”
Matt Tristram, managing director of master broker Loans Warehouse, welcomed the return.
He said: “We’re encouraged by the OneSavings Bank backed lender and look forward to working with what will be some exciting products. It’s another bank in the secured loans market and that can only be good for the sector.”
