A higher renewal rate can still leave your money in the wrong place. Decide what the money needs to do before comparing percentages.
Read the maturity letter before choosing
Your NS&I maturity letter shows the product, maturity date, proposed term, rate, instruction options and registered bank account.
Find the six details that matter
Check the product, exact maturity date, renewal term, interest payment method, instruction deadline and registered bank details before comparing anything else.
Not every NS&I holding matures
Premium Bonds, Direct Saver and Income Bonds work differently from fixed-term holdings, so do not treat them as a maturity decision. Early withdrawal from a fixed-term product can have separate rules, including lost interest.
A maturity letter gives an offer, not personal advice. Its proposed rate may be good, but the term, access rules and your next need for the money matter just as much.
Match the money to access, tax and income
Renew only when the new term matches your deadline, income needs and tax position.
| Action | Access to cash | Tax treatment | Usual route | Best fit |
|---|
| Renew with NS&I | Often restricted until term end | Interest may be taxable | Letter, online account or contact route | Money not needed during the new term |
| Withdraw to bank | Available after payment clears | Interest may use Personal Savings Allowance | Nominated UK bank account | Near-term spending or emergency cash |
| Pay into a Cash ISA | Depends on the ISA terms | Interest is tax-free | ISA provider and annual allowance | Savings likely to create taxable interest |
| Buy Premium Bonds | Can be cashed in, subject to processing | Prizes are tax-free | NS&I account | Cash reserve where no fixed income is needed |
Check the date you may need it
Money needed within the next 12 months is usually better kept accessible than placed into a new two or three-year term.
Decide whether tax-free interest matters
A Cash ISA can shelter interest from UK tax, but the £20,000 annual allowance may already be used by other ISA payments. Your Personal Savings Allowance can also cover taxable interest, depending on your tax band.

Our recommendation
A simple financial document organiser can keep your NS&I letter, ISA records and bank details together while you compare options. It is most useful when a maturity date is close and paperwork is spread across drawers.
- Keeps NS&I letters and instruction references in one place
- Separates current ISA documents from taxable savings records
- Makes it easier to check the nominated bank account before withdrawal

Give instructions early and keep proof
Start roughly one month before maturity, confirm online access and bank details, then save evidence of your instruction.
Follow a calendar, not a guess
Read the letter a month before maturity, check your login and nominated account two to three weeks beforehand, and send instructions before the stated deadline.
Fix bank details and access problems
Update bank details only through NS&I’s official process and allow time for identity checks. If login fails, contact NS&I promptly rather than waiting until the deadline.
A switch is not always the same as a withdrawal followed by a new application. If your NS&I letter offers an eligible NS&I savings renewal or another NS&I account, follow the stated instruction route and check whether the balance can be moved directly at maturity. For other destinations, you may need to withdraw savings to bank first and then make a separate deposit. This matters especially for fixed-term savings: a direct renewal instruction can keep the money continuously invested, whereas a bank withdrawal may leave a gap before it reaches the new account.
If the destination is a Cash ISA, establish whether the money is a new subscription or an ISA transfer before acting.
If an NS&I maturity letter has not arrived about a month before the maturity date, do not assume the account will renew or pay out in the way you prefer. Sign in to your NS&I account, check that your postal address and contact details are current, and use NS&I’s official contact details if the product or deadline is still unclear. Where maturity falls on a weekend or bank holiday, use the date and cut-off shown in the letter rather than assuming you can wait until the next working day.
Instructions sent after the deadline may be handled under the product’s default maturity terms, so retain any confirmation number, screenshot or postal proof.
Before choosing an option, turn the letter into a short action plan:
- note the maturity date, the last date for instructions, the available channel and what should happen next. An online instruction may produce an on-screen confirmation immediately, while a postal or telephone route can require more time to be received and processed. A renewal normally places the balance into the offered term
- a withdrawal sends it to the nominated UK bank account once payment is processed
- an ISA option may require steps with the receiving provider as well
This comparison prevents a good renewal rate from distracting from the deadline, access to savings and the expected payment route.
Avoid treating premium bonds like fixed savings
Premium Bonds do not mature and should be assessed separately from fixed-term NS&I savings.
Separate maturity from early withdrawal
A matured certificate has reached its agreed end date, while an early withdrawal may lose interest or face restrictions under the exact product terms.
This guide is not a substitute for personal financial advice where debt, means-tested benefits, complex tax, an inheritance or a large sum is involved. It also does not apply as the main guide if the holding has already been closed or paid out.
Make a six-point note now: product, date, term, rate, access rule and bank account. It makes the final decision easier.
What people ask
What happens when my NS&I bond matures?
NS&I usually lets you renew, withdraw or choose another available option. Follow the deadline, rate and term in your specific letter.
Can I withdraw NS&I money to my bank account?
You can usually request payment to your registered UK bank account. Check it is still open before instructing withdrawal.
How long does an NS&I maturity payment take?
A payment may show between 2 and 5 working days after maturity. Bank holidays, checks and incorrect details can delay it.
Do premium bonds mature like NS&I bonds?
Premium Bonds have no fixed end date. They remain in the prize draw until you cash them in.
Should I put matured NS&I money into a cash ISA?
A Cash ISA can suit money that would otherwise earn taxable interest and fits within your annual ISA allowance. Compare access and rates first.
Does HMRC know about my NS&I interest?
Taxable NS&I interest can count towards your Personal Savings Allowance. ISA interest and Premium Bond prizes are tax-free.
What if I cannot log in to my NS&I account?
Contact NS&I through its official details as soon as possible, ideally two to three weeks before maturity.
Is NS&I protected by the FSCS?
NS&I savings are backed by HM Treasury, not the Financial Services Compensation Scheme.
The essential points:- Read the maturity letter as a set of choices, not an automatic renewal form.
- Choose based on when you need the money, whether you need income and how interest will be taxed.
- Premium Bonds do not have a maturity date and should be assessed separately.
- Check bank details and account access about one month before the deadline, then keep proof of your instruction.
