Principality Building Society has introduced a new two-year fixed rate bond offering a guaranteed 4.25 per cent AER.
The firm says the bond makes "a great home" for people's capital if they are keen to get the most out of savings.
It is open to investments from £500 up to £1 million, with interest payable on a monthly or yearly basis according to consumer choice.
Savers can also make additional deposits into their two-year bond whilst it remains on sale.
James Wright, marketing director of Principality Building Society, said that just because the UK is still in a low interest rate environment, it does not mean savers have to suffer low returns on their money.
He added: "With Principality's new two-year bond, people know that their money is being looked after by a building society with a 150-year history, an award-winning reputation for consistently high interest rates, and of course a guaranteed return on their savings."
