Probate for Premium Bonds and NS&I: England Guide

Premium bonds and NS&I accounts are among the most commonly held savings products in England — and also among the most misunderstood when someone dies. Unlike high-street bank accounts, NS&I applies its own rules about when it will release funds without probate, and those rules are stricter than most other institutions.

Here is how probate interacts with premium bonds, NS&I savings, and Nationwide building society accounts.

Premium Bonds After Death: What Happens First

Premium bonds are issued by NS&I (National Savings and Investments), a government-backed savings institution. They cannot be transferred to another person — they must be cashed in. Once notified of a death, NS&I will hold the premium bonds in the estate for up to 12 months, during which time they continue to be included in the monthly prize draw.

If a bond wins a prize during this 12-month holding period, the prize is paid to the estate as a cash amount.

After 12 months, NS&I automatically cashes in the bonds and holds the proceeds until the estate is settled. No further draws after 12 months.

To claim the premium bonds, the executor submits a completed claim form (available from NS&I's bereavement line) along with the death certificate and proof of the executor's identity.

Does NS&I Require Probate?

NS&I applies one of the stricter probate thresholds among major UK financial institutions. This is the area where executors run into problems, particularly when they have dealt with other banks without needing probate and assume the same will apply to NS&I.

NS&I's general approach:

Premium bonds with no will (intestacy): NS&I typically requires a Grant of Probate or Letters of Administration for any premium bond holding. Even modest amounts may require formal authority where there is no will.

Premium bonds with a valid will: NS&I may release smaller holdings — typically up to £5,000 — without probate, if a valid will exists and the executor can provide satisfactory evidence of their appointment. For holdings above this level, probate is usually required.

NS&I savings certificates and Fixed Rate ISAs: Similar thresholds apply. NS&I is more conservative than most high-street banks because it is a government institution operating under statutory guidelines, not commercial risk appetite.

The specific threshold at the time of dealing should be confirmed directly with NS&I's bereavement team, as these limits can and do change. NS&I's bereavement line is 0800 092 9999 and is open on weekdays.

Compare this to major high-street banks, which typically release up to £50,000 without probate where a valid will exists — a threshold ten times higher than NS&I's standard limit.

Nationwide Building Society Probate Threshold

Nationwide operates under building society rules rather than the commercial banking model of PLC banks. Its bereavement process is managed through its dedicated team, and the probate threshold is broadly in line with other major building societies.

Nationwide's general threshold is approximately £50,000 for accounts held in a sole name where a valid will exists. For accounts above this amount, or where there is no will, Nationwide typically requires either the Grant of Probate or Letters of Administration before releasing funds.

For jointly held accounts — where the deceased and the survivor were both named account holders — the account passes to the survivor automatically on production of the death certificate. No probate is required for the joint element.

Nationwide's process requires:

• The deceased's passbook or account details
• An original or certified copy of the death certificate
• Proof of the executor's identity (passport, driving licence)
• A completed claim form from Nationwide's bereavement team

For amounts above the threshold, the sealed Grant of Probate must be presented before Nationwide will release funds.

Understanding the Statutory vs Commercial Threshold Gap

This is a point of genuine confusion for many executors. The Administration of Estates (Small Payments) Act 1965 sets a statutory limit of £5,000 for releasing funds without legal authority. Many executors assume this means no bank will release more than £5,000 without probate.

In practice, commercial banks and building societies set their own internal thresholds based on risk tolerance and FCA Consumer Duty obligations. Major high-street banks have raised their effective thresholds to £50,000 or more, making probate unnecessary for a large proportion of estates with bank account assets.

NS&I, operating as a government-backed institution rather than a commercial entity, adheres more closely to the statutory framework — which is why its limits are lower.

The key practical point for executors: always contact each institution directly to confirm its current bereavement policy before assuming probate is or is not required. Thresholds change, and the consequences of assuming incorrectly — either delaying an application unnecessarily or attempting to claim funds without the required authority — both have real costs.

What Probate Is Not Required For

Certain categories of NS&I products fall outside the probate framework entirely:

NS&I Direct Saver and Premium Bonds where a named beneficiary exists: NS&I does not formally allow beneficiary nominations in the way that life insurance policies do, so this category is largely not applicable in practice. NS&I products generally form part of the estate and must be administered through the usual probate process.

Joint accounts: As with all UK financial institutions, joint accounts pass to the surviving account holder by survivorship. NS&I joint accounts transfer on presentation of the death certificate without probate.

Small amounts where NS&I exercises discretion: In certain circumstances — particularly where the total NS&I holding is very modest and the deceased left a valid will — NS&I may exercise discretion to release funds without formal probate. This is not guaranteed, but NS&I's bereavement team can advise on whether discretion might apply in a specific case.

Practical Steps for NS&I and Nationwide Claims

Step 1: Contact NS&I's bereavement team (0800 092 9999) and Nationwide's bereavement team immediately after obtaining the death certificate. Do not wait until probate has been granted to make initial contact — begin the notification and gather the documentation list early.

Step 2: Provide the death certificate and the executor's identification.

Step 3: Ask explicitly about the current threshold for releasing funds without probate, and whether the specific holding amount falls above or below it.

Step 4: If probate is required, include NS&I and Nationwide in your date-of-death balance requests for estate valuation purposes. These figures are needed before completing the probate application and, where applicable, the IHT400.

Step 5: Request sufficient sealed copies of the Grant of Probate at the time of application. NS&I will typically require one original sealed copy. Nationwide will require one sealed copy. Order all copies upfront — the fee drops significantly if ordered alongside the initial application.

Premium Bond Prizes Won After Death

If a premium bond wins a prize between the date of death and the point of claiming, the prize goes to the estate as cash. This is important for the estate valuation: the prize increases the estate's asset value and may affect whether the estate remains below the IHT threshold.

After the 12-month holding period expires, the bonds are converted to cash automatically. No further prizes can be won. If the estate takes more than 12 months to administer (common in complex estates or where there are probate delays), this timing matters.
