NS&I Cash ISA

The NS&I Cash ISA is no longer on sale

If you already have an NS&I Cash ISA, you can carry on using it but deposits can no longer be made at a Post Office® branch or at a bank/building society. You can still make deposits by phone, post, standing order and electronic funds transfer.

If you want to open a new cash ISA with NS&I, have a look at our Direct ISA which can be managed by phone and online.

Higher ISA allowance

From 6 October 2009 customers who will be 50 years or over on 5 April 2010 can invest up to £5,100 in a cash ISA. From 6 April 2010 all ISA savers will be eligible for the higher allowance.

Cheque and debit card clearance

You’ll start earning interest on all deposits from the day we receive them. Cheque and debit card deposits will be available for withdrawal from the seventh working day (ie excluding weekends and English bank holidays).

For example, if we receive your cheque or debit card details on a Monday, your payment will be cleared on the Tuesday of the following week. After close of business on the seventh working day, you can be certain that the money will not be reclaimed from your account as a result of the cheque bouncing or the payment not being authorised. Allow one additional day for each English bank holiday.

We will bank your cheque, or start to process your debit card payment, as soon as we receive it, so please make sure you have enough money in your account at the time.
