A rate of 2.75 per cent gross per annum is being offered by a new short-term fixed-rate postal bond from Leeds Building Society.
Individuals who opt for the offer can get at their money without notice or penalty.
The society's sales and marketing director Kim Rebecchi stated the combination of being able to access the funds at any time and a fixed return rate will be attractive to consumers.
"Savers know exactly what they are getting and, if the customer's circumstances change, they can withdraw their funds at anytime, delivering complete peace of mind," she said.
Ms Rebecchi added there is no need for set monthly sums to be added to the account or for linked products to be taken on.
A minimum investment of £1,000 is required to open the bond and this can be done at any of the firm's 67 branches in the UK, Ireland and Gibraltar.
