Frequently asked questions

If your client’s NS&I account is already open, they can top up their account by bank transfer. Full details of how to do this for each of our accounts can be found on our website.

If your client wants to open a new NS&I account online with a large amount, please ask them to check their bank’s upper limit for debit card payments (we can accept up to a maximum of £99,999). If the limit is lower than the amount they want to deposit, they can open the account with a smaller amount and then make a larger deposit by bank transfer when the account is up and running.

Your clients can open a new NS&I account using the funds from a maturing Bond – we call this ‘switching’. To switch to NS&I Premium Bonds, Direct Saver or Direct ISA, your clients can do this online by visiting nsandi.com/forms then clicking on the switching link for one of these accounts.

To switch into Income Bonds either as a new Income Bonds customer or existing customer, you should use the Income Bonds application form. Please note that the deposit form doesn’t have the appropriate sections that instruct us to pull the funds from another NS&I product.

If you need more details to switch to Income Bonds or Investment Account, you or your clients can call us on 08085 007 007.

For clients who want to move their maturing funds to an existing Direct Saver or Investment Account, they will need to give the relevant details with their maturity instructions.

If you haven’t done so already, you must first send us a completed Terms of Business (ToB) agreement by post. Once we have received this, you will receive an activation email within five working days.

This email will be valid for 14 days and will allow you to go online and activate your registration.

A senior representative of the firm must complete the initial registration, and they will be provided with administration rights, ie becoming ‘super-users’. This will allow them to add and remove additional users within the firm and determine individual access rights (ie admin access or standard access).

Once registered for the service, you will be able to view any mutual NS&I customer accounts following receipt of a Letter of Authority (LoA) for each client you wish to view.

When we receive a completed Letter of Authority, we will also send you an acknowledgement letter. This will contain a reference number which you can use to make client information requests over the phone. Please note that this is separate to your online log in credentials.

Your clients will continue to receive 0.01% interest in addition to the index-linking. Here is an illustration of what your clients could expect to receive from a £1,000 investment based on the June 2023 RPI index, and what the return could be based on CPI.

These are illustrations only, so they don’t take into account your client’s individual circumstances. They assume that your clients don't make any withdrawals during the term.

The rates of inflation can go up or down so the illustrations are not a guarantee of the return your clients will receive. The actual return your clients receive will depend on the levels of the relevant index that apply at the start and end of each investment year.
