The new product is joined with another savings option.
A new
cash ISA has been launched by the Post Office, along with another
savings account option.
The fixed rate cash ISA and growth bond are among the most popular
saving account choices and they will offer borrowers market-leading rates.
Director of savings Richard Norman comments: "We know that many savers are feeling hard done by due to the low base rate resulting in lower returns on their savings.
That's why we're always looking for ways to improve our savings offer."
He says the latest issues should make customers more aware of the company's ongoing commitment to offer them the best products.
Each one can be opened with a minimum deposit of £500 and the three-year cash ISA offers up to four per cent tax-free returns.
Another alternative from the Post Office might be the online saver, which has unlimited free withdrawals and allows people to set aside between £1 and £2 million.
