NS&I has relaunched its British Savings Bonds with updated rates for 2025, offering fixed-term savers the chance to lock in guaranteed returns through Guaranteed Growth Bonds. The latest 1-year Issue 88 delivers a 4.07% gross/AER return, though this represents a slight decrease from the previous Issue 87 rate of 4.20%. These government-backed products remain among the most secure savings options available in the UK market.
The relaunch brings renewed attention to NS&I’s suite of fixed-term savings products, which had seen significant rate improvements throughout 2025 as the provider sought to attract investors seeking certainty over flexibility. Unlike Premium Bonds, which offer a probabilistic prize-based return, British Savings Bonds provide guaranteed interest payouts—appealing to savers who prefer predictable outcomes over lottery-style rewards.
For those considering their savings options, understanding the current rate environment, tax implications, and how British Savings Bonds compare to alternatives becomes essential for informed financial decisions.
What are the current NS&I British Savings Bonds rates?
NS&I’s British Savings Bonds come in two distinct product types: Guaranteed Growth Bonds, where interest compounds and is paid at maturity, and Guaranteed Income Bonds, which pay interest monthly. Both varieties share the same underlying fixed-term structure and government backing.
Active Issue Rate Breakdown
| Term | Issue | Guaranteed Growth Bonds (gross/AER) | Guaranteed Income Bonds (gross/AER) |
|---|---|---|---|
| 1-year | 88 | 4.07% | 4.00% / 4.07% |
| 2-year | 76 | 3.98% | 3.91% / 3.98% |
| 3-year | 78 | 4.02% | 3.95% / 4.02% |
| 5-year | 70 | 4.05% | 3.98% / 4.05% |
The 1-year Guaranteed Growth Bonds Issue 88 currently offers 4.07% gross/AER, representing a reduction from the November 2025 Issue 87 rate of 4.20%. According to NS&I’s official corporate announcements, these rate adjustments reflect ongoing market positioning strategies.
Key Insights from the Relaunch
- The 1-year Issue 88 rate of 4.07% marks a decrease from Issue 87’s 4.20%, though rates remain competitive against market averages
- NS&I British Savings Bonds continue to exceed the average savings rate of approximately 3.42% reported across the market
- All terms from 1 to 5 years remain available, maintaining the full product range launched during 2025 updates
- Investment limits range from £500 minimum to £1 million maximum per person per issue
- Rates are guaranteed for the fixed term once invested, providing complete certainty on returns
- The products buck broader market trends where rates have generally been falling
While NS&I rates are competitive among government-backed providers, independent banks occasionally offer higher rates. Monument Bank, for example, has offered 1-year fixed rates around 4.47%. However, NS&I products carry the unique advantage of government backing rather than reliance on the Financial Services Compensation Scheme.
Are British Savings Bonds tax-free?
British Savings Bonds are not tax-free investments. Unlike Premium Bonds, which offer tax-free prizes through the prize fund mechanism, interest earned on British Savings Bonds is paid gross and counted as savings income subject to taxation.
However, the Personal Savings Allowance provides meaningful protection for many investors. Basic-rate taxpayers can earn up to £1,000 in savings interest tax-free annually, while higher-rate taxpayers receive a £500 allowance. Additional-rate taxpayers do not qualify for the allowance, meaning all interest falls within their marginal tax band.
Tax Treatment Summary
- Interest is paid gross (without tax deducted at source)
- All interest counts as taxable savings income
- Basic-rate taxpayers: £1,000 Personal Savings Allowance
- Higher-rate taxpayers: £500 Personal Savings Allowance
- Additional-rate taxpayers: no allowance applies
- Interest is added to other savings and investment income when calculating tax liability
For basic-rate taxpayers with the full £1,000 Personal Savings Allowance available, the first £24,390 of British Savings Bonds investment at 4.07% would generate tax-free interest equivalent to the allowance threshold. Those with larger holdings may benefit from spreading investments across accounts or considering the tax treatment as part of broader financial planning.
Unlike the prize-based structure found in Premium Bonds, where prizes fall outside the Personal Savings Allowance framework, British Savings Bonds interest is treated as ordinary savings income. This distinction matters for higher-rate and additional-rate taxpayers who may face a larger tax burden on returns.
What are NS&I Guaranteed Growth Bonds (British Savings Bonds)?
Guaranteed Growth Bonds represent one of NS&I’s core savings products, forming part of the broader British Savings Bonds family. These fixed-term investments offer guaranteed returns with no exposure to market fluctuations, making them particularly attractive to risk-averse savers seeking certainty.
Product Structure and Terms
The bonds operate on a straightforward basis: investors deposit funds for a fixed period, and interest accrues at a guaranteed rate paid upon maturity. This structure contrasts sharply with variable-rate products where returns can fluctuate throughout the investment term.
- Fixed terms of 1, 2, 3, or 5 years available
- Minimum investment of £500 per bond issue
- Maximum investment of £1 million per person per issue
- No early access permitted during the fixed term
- Early withdrawal results in forfeiture of interest earned
- Transfers to another person do not preserve accumulated interest
Applications can be submitted through multiple channels: online via the official NS&I website, by telephone, by post, or through appointed agents. Current product availability and terms are detailed on the NS&I website, where new issues are released periodically throughout the year.
Eligibility Requirements
| Requirement | Details |
|---|---|
| Residency | UK residents, including Crown Dependencies, Channel Islands, and British Forces overseas |
| Minimum Age | 16 years or older |
| National Insurance Number | Required for all individual applicants |
| Entity Types | Trusts and companies may also apply |
Once invested in a British Savings Bond, funds remain locked for the entire fixed term. There is no provision for early access, and withdrawing funds before maturity results in forfeiture of all accumulated interest. At maturity, investors have the option to withdraw their funds or reinvest into available issues.
How do NS&I British Savings Bonds relate to Premium Bonds?
British Savings Bonds and Premium Bonds share the same issuer—NS&I—but differ fundamentally in their return mechanisms, accessibility, and tax treatment. Understanding these distinctions helps investors choose the product that aligns with their priorities.
Structural Differences
Premium Bonds operate as a lottery-style investment where returns come from a monthly prize fund rather than guaranteed interest. The current prize rate stands at approximately 4.40%, with prizes ranging from £25 to £1 million tax-free. However, there is no guaranteed return—prizes are entirely probabilistic, meaning some holders may receive nothing while others win substantial amounts.
British Savings Bonds, by contrast, provide a fixed interest rate that never changes throughout the term. Investors know precisely what their investment will be worth at maturity, offering complete predictability. This guarantee comes at the cost of no access to funds until the bond matures and the absence of any prize element.
Access and Investment Limits
- Premium Bonds allow fully flexible access with no fixed term
- British Savings Bonds require commitment for 1, 2, 3, or 5 years
- Premium Bonds: £25 minimum, £50,000 maximum per person
- British Savings Bonds: £500 minimum, £1 million maximum per issue
- Premium Bonds prizes are tax-free
- British Savings Bonds interest is taxable (subject to Personal Savings Allowance)
Premium Bonds suit savers who prioritise flexibility and are comfortable with probabilistic returns, particularly those who might benefit from the tax-free prize structure. British Savings Bonds appeal to investors seeking guaranteed returns and those with larger sums who want certainty over the investment term. The higher maximum investment limit of £1 million also makes British Savings Bonds more suitable for substantial fixed-term deposits.
For those exploring other financial options alongside savings products, understanding how personal lending compares can be valuable. Resources on topics like best personal loan rates provide context for how borrowing costs compare to savings returns.
How do NS&I rates compare to the broader market?
NS&I’s British Savings Bonds maintain competitive positioning within the fixed-rate savings market, though independent providers frequently offer higher rates. According to analysis from independent financial commentators, the NS&I 1-year rate of 4.07% sits above average market offerings of approximately 3.42% but below the most competitive independent providers.
| Provider | 1-Year Rate (AER) | Notes |
|---|---|---|
| NS&I Issue 88 | 4.07% | Government-backed, £500-£1m limits |
| Monument Bank | 4.47% | Higher rate, protected by FSCS |
| Market Leaders | ~4.2%+ | Varies; check current offerings |
The comparison reveals that NS&I’s government backing comes with a modest rate penalty compared to independent banks, which rely on the Financial Services Compensation Scheme for protection rather than government guarantee. Savers must weigh the certainty of NS&I’s government backing against potentially higher returns available elsewhere.
Rates across the market have experienced general downward pressure, making NS&I’s relatively stable positioning notable. The provider has continued offering competitive rates even as other institutions reduce their offerings, bucking broader market trends. Financial comparison platforms track these rate movements regularly, helping savers identify optimal placement opportunities.
When did NS&I launch and update British Savings Bonds?
NS&I has periodically updated British Savings Bonds throughout 2025, with significant rate changes occurring in April and November. Understanding this timeline helps contextualise the current offering within the broader evolution of these products.
- : New issues launched across 1, 2, 3, and 5-year terms with increased interest rates, marking a significant expansion of the product range
- : Issue 87 launched with further rate improvements, reaching 4.20% gross/AER for 1-year Guaranteed Growth Bonds
- : Issue 88 replaced Issue 87 with adjusted rates of 4.07%, reflecting market repositioning
The April 2025 relaunch represented a substantial refresh of the British Savings Bonds proposition, bringing multiple term lengths back into active availability. Current and historical rate information is maintained on NS&I’s official interest rates page, allowing investors to track changes over time.
What is established versus what remains uncertain?
When evaluating British Savings Bonds as a potential investment, distinguishing between confirmed facts and areas of uncertainty helps set appropriate expectations.
Established Information
- Current 1-year Issue 88 rate: 4.07% gross/AER
- Government-backed security through HM Treasury
- Fixed terms of 1, 2, 3, or 5 years available
- Interest paid gross, subject to Personal Savings Allowance
- Minimum investment: £500
- Maximum investment: £1 million per person per issue

Information That Remains Uncertain
- Future rate changes for upcoming issues
- Duration of current Issue 88 availability
- Timing of future issue launches
- Whether rates will rise or fall in subsequent issues
- Specific dates when new issues may replace current ones
NS&I operates with flexibility regarding issue availability, releasing new products periodically rather than on a fixed schedule. This structure means investors must monitor the official website for current availability rather than relying on predictable launch dates.
Why does NS&I offer these savings products?
NS&I exists to serve the UK public by offering savings products that help fund government borrowing while providing individuals with secure investment options. The organisation, which traces its roots back to the post-war era, operates under government guarantee and uses customer deposits to finance public sector activities.
The British Savings Bonds sit alongside Premium Bonds and direct savings accounts as part of NS&I’s product suite. Each product serves different investor priorities: Premium Bonds for those seeking excitement and tax-free potential, British Savings Bonds for guaranteed returns over fixed terms, and direct savings accounts for accessible emergency funds.
The government’s stake means deposits are 100% secure in a way that goes beyond even the generous FSCS protection available through banks. This unique positioning attracts investors who prioritise absolute capital security over maximum returns, particularly those with substantial sums approaching or exceeding the FSCS £85,000 limit.

Summary: Should you consider NS&I British Savings Bonds?
NS&I British Savings Bonds represent a compelling option for UK savers prioritising government-backed security and guaranteed returns over flexible access. The current Issue 88 rate of 4.07% gross/AER remains competitive against average market offerings, though independent providers may offer higher returns with different protection arrangements.
The 1-year fixed term provides a reasonable balance between commitment and accessibility for those who know their funds will remain untouched. The £500 minimum makes the product accessible to most investors, while the £1 million maximum accommodates substantial holdings. Tax treatment through the Personal Savings Allowance benefits basic and higher-rate taxpayers, though the absence of any tax-free element distinguishes these from Premium Bonds.
For those comparing across the financial landscape, examining how savings products integrate with borrowing options offers broader perspective. Understanding the full range of financial services, including Virgin Money online banking, helps build comprehensive financial awareness.
What is the minimum age to invest in NS&I British Savings Bonds?
Applicants must be aged 16 years or older to invest in British Savings Bonds. This age requirement applies to individual applicants, and the investments are available to UK residents including those in Crown Dependencies, Channel Islands, and British Forces overseas.
Can I withdraw my money early from British Savings Bonds?
No early access is permitted during the fixed term. Attempting to withdraw funds before maturity results in forfeiture of all accumulated interest. At maturity, investors can withdraw their funds or reinvest into available issues.
Are Premium Bonds better than British Savings Bonds?
Neither product is universally better—they serve different priorities. Premium Bonds offer flexible access and tax-free prizes but no guaranteed return. British Savings Bonds provide guaranteed fixed rates with no lottery element. The choice depends on whether you prioritise certainty (British Savings Bonds) or potential prizes with flexibility (Premium Bonds).
How is interest paid on Guaranteed Growth Bonds?
Interest on Guaranteed Growth Bonds compounds and is paid at maturity, along with the original capital. This differs from Guaranteed Income Bonds, which pay interest monthly. Both types share the same fixed-term structure and interest rates.
What happens when my British Savings Bond matures?
At maturity, investors receive notification and can choose to withdraw their funds or reinvest into currently available British Savings Bond issues. No action is required for automatic reinvestment if you have selected that option; otherwise, funds are returned to your linked account.
How do NS&I rates compare to high-street bank savings rates?
NS&I rates generally exceed average savings rates available across the market. However, some independent providers offer higher rates than NS&I. The trade-off involves government backing (NS&I) versus FSCS protection (banks). NS&I products suit those prioritising maximum security over maximum return.
