How to Fill Out and Submit the NS&I Premium Bonds Withdrawal Form

To cash in Premium Bonds, submit the NS&I Premium Bonds withdrawal form online, over the phone, or on paper to NS&I at Sunderland SR43 2SB. You’ll need your holder’s number and the sort code and account number of a UK bank or building society account in your name. Payment usually reaches your account within three to five working days, and there’s no notice period or penalty for cashing in.¹

Cash In Online

The quickest route is NS&I’s website. If you already have an online or phone account, log in and use the “Cash in” option on your dashboard, then choose a full or partial withdrawal and confirm.

You don’t need a registered profile. NS&I offers a standalone online form anyone can use, provided you have your holder’s number and UK bank details to hand.² If you want some bonds to stay in the monthly prize draw, pick the option to cash in specific bonds and have your bond record ready so you can identify which ones to sell.¹

Fill Out the Paper Form

If you’d rather post the request, download the cashing-in form from NS&I’s downloads and forms page.³ No printer? Call NS&I and they’ll put a copy in the post to you.¹

The form asks for:

Your holder’s number. This is the identifier for your bond holdings and can be 10 digits, 9 digits, or 8 digits followed by a letter. It is not the same as the personal NS&I number used to log in online, so check your original bond certificate or any letter from NS&I.⁴
Your bank or building society sort code and account number, so NS&I can pay you electronically.
The withdrawal amount. State whether you are cashing in all your bonds or a specific amount. For a partial withdrawal, you can list the individual bonds you want to sell if you’d like particular ones to stay in the draw.
Your signature and the date, both written by hand. Unsigned forms are returned unprocessed.

If you still have the original bond certificates for the bonds you’re cashing in, send them with the form. NS&I will process the request without them, but including them avoids follow-up correspondence.

Where to Post the Form

Send the completed form to NS&I, Sunderland SR43 2SB.⁵ No street name is needed; the postcode alone routes the mail. If you’re enclosing original certificates, use a tracked or signed-for service.

How Long It Takes

Once NS&I has the request, the money typically reaches your bank in three to five working days.¹ Postal requests take a little longer because of mailing time. NS&I confirms the transaction either by letter or as a secure message in your online account, showing the bonds sold and your updated balance.

Partial Withdrawals and Minimum Holdings

Premium Bonds are issued in £1 units with a minimum purchase of £25.⁶ NS&I doesn’t set a separate minimum withdrawal amount, and you can cash in all or part of your bonds at any time. Each £1 bond is a separate entry in the monthly draw, so a partial withdrawal reduces your chances proportionally. The maximum anyone can hold is £50,000.¹

Cashing In a Child’s Premium Bonds

The parent or guardian registered as the “responsible person” manages a child’s bonds until the child turns 16.⁷ To withdraw, use the dedicated online form for cashing in a child’s bonds, which is separate from the standard adult form and available on NS&I’s withdrawal page.² You’ll need the child’s holder’s number and your own bank details. A paper version can also be downloaded and posted to the Sunderland address.

From the child’s 16th birthday, control of the account passes to them, and they handle withdrawals themselves.

Withdrawing Under a Power of Attorney

If you hold a Power of Attorney for a bondholder, register it with NS&I before you try to withdraw.

A Lasting Power of Attorney in England and Wales must first be registered with the Office of the Public Guardian. If it was registered on or after 1 January 2016, you’ll receive a reference number and activation key by post, which you use to set up an LPA account on NS&I’s website. Alternatively, give NS&I the unique OPG code by online form or letter; the code is valid for 30 days.⁸
For an Ordinary Power of Attorney, post the original document or a certified copy to NS&I using a secure service.
For a Court of Protection Order, post the original or a certified copy. The order should be sealed or carry the blue office copy stamp.

Scotland’s Continuing Power of Attorney and Northern Ireland’s Enduring Power of Attorney follow the same general approach: register with the relevant Office of the Public Guardian first, then share the details with NS&I by post or online form.⁸

If the Bondholder Has Died

There’s no rush to cash in. Premium Bonds remain eligible for monthly prize draws for up to 12 months after the holder’s date of death, and any prizes won in that window are paid by cheque to whoever is entitled to the funds.⁹ To start a bereavement claim, the executor or administrator contacts NS&I with the deceased’s details and their own, along with bank details for payment. NS&I will say whether a Grant of Representation is needed; this is generally requested when the total NS&I holdings are £5,000 or more, though NS&I can ask for one regardless of the amount.

Can’t Find Your Holder’s Number?

Without a holder’s number you can’t complete the form, but NS&I runs a free tracing service. Download the tracing form from NS&I’s website, or write to Tracing Service, NS&I, Sunderland SR43 2SB with your full name and current address, your address at the time of investment and any previous addresses, any previous name such as a maiden name, the approximate date you opened the account, and the approximate amount invested.¹⁰ Sign and date the letter. NS&I aims to confirm your account within one month, after which you can submit the withdrawal in the usual way.
