NS&I Leaflet

Contact National Savings & Investments (NS&I) advisors for free by calling their UK freephone number 0808 500 7007 to buy premium bonds, to confirm the annual interest rates which will grow your money and for confirmation of the prize amounts available in their monthly draws.

You should contact them as quickly as possible if you believe you have won a prize, even if it has previously been unclaimed for a period of time. They may also contact you directly if you have won the current top prize of £1 million (GBP) so ensure that you phone their helpline when you move home to ensure your account details are correct.

You can also call this helpline to query a charge on your ISA account and to check if there any restrictions on how often you can withdraw money from your savings funds as some require a period of up to a year before you can make withdrawals without affecting your accumulated interest. Similarly you can call this helpline to check how many savings accounts you are permitted to have during a specific year as there are limitations due to tax purposes.

Lines are open 24 hours a day, seven days a week however there may only be an automated service at night and during bank holidays such as Christmas Day. Calls are free of charge from all UK landline and mobile devices however calls to NS&I from payphones may not be accepted.

Phone NS&I customer service advisors from abroad by calling their dedicated international contact number +441253 832 007 to discuss your premium bonds, ISA accounts and savings funds from overseas.

You should note that this is not a freephone service and the exact cost will depend on which country you are phoning the National Savings & Investments department from, however it is likely that you will pay more than making the equivalent UK call.
