A fixed-rate bond — also commonly called a fixed-term deposit or fixed-rate savings account — locks your money away for a set period in exchange for a guaranteed interest rate. The rate does not change for the duration of the term. Here is how fixed-rate bonds work mechanically, what to expect at maturity, and how they compare with the alternatives.
What is a fixed-rate bond?
A fixed-rate bond — also commonly called a fixed-term deposit or fixed-rate savings account — is a savings account that pays a guaranteed interest rate for a set term, typically one, two, three or five years. You deposit money at the start of the term, usually during a limited funding window. The account pays the fixed rate specified under its terms for the agreed period. When the term ends, the bond matures and you receive your principal back together with the interest you have earned. (Source: Uswitch, citing Moneyfacts, June 2026; Raisin UK.)
The terms "fixed-rate bond", "fixed-term deposit" and "fixed-rate savings account" are commonly used to describe similar types of fixed-term savings accounts. They are not the same as government bonds (gilts) or corporate bonds traded on financial markets.
How a fixed-rate bond works — step by step
Opening the account: You choose a term and deposit a lump sum. Most providers set a minimum deposit — typically between £500 and £10,000, though some accept as little as £1.
The funding window: After opening, most providers allow deposits during a limited funding period — typically seven to fourteen days. Once that window closes, further deposits are usually not accepted. Check the funding deadline and arrange any intended deposits within the permitted window. (Source: money.co.uk; Raisin UK.)
Earning interest: The account pays the fixed rate specified under its terms for the agreed period, regardless of changes to Bank Rate or market rates. How interest builds depends on the account terms. If interest is added to the balance and itself earns interest, returns compound. If interest is paid away to another account, it does not remain in the bond to compound. Check whether the quoted AER assumes interest is retained. (Source: MoneySuperMarket, July 2026.)
Maturity: When the term ends, the provider will typically contact you 14 to 30 days before maturity to ask what you would like to do. Common options include withdrawing to your nominated bank account, rolling into a new account, or transferring elsewhere. What happens if you do not respond varies by provider — check the maturity terms before opening. Set a reminder for 30 days before your maturity date. (Source: money.co.uk.)
Early access: Most fixed-rate bonds do not permit withdrawals during the term. Some providers allow early closure with a penalty — usually the loss of a significant number of days' interest. Others do not permit early closure at all. (Source: MoneySuperMarket, July 2026.)
The account pays the fixed rate specified under its terms for the agreed period. If Bank Rate rises or falls after you open the bond, your rate stays the same. This is the core trade-off: certainty in exchange for committing your money for the agreed period.
Common terms and their commitment
| Term |
Commitment |
What it means |
| 3–6 months | Shorter | Money committed for several months |
| 1 year | 12 months | Rate fixed for approximately one year |
| 2 years | 24 months | Longer commitment to the agreed rate |
| 3 years | 36 months | Money normally inaccessible for around three years |
| 5 years | 60 months | Long-term commitment to today's fixed rate |
Terms from three months to seven years are available in the UK market, though one and two-year bonds are the most widely offered. (Source: Raisin UK; money.co.uk.)
How fixed-rate bond rates compare
There is no fixed rule that longer-term bonds pay higher rates than shorter terms. Rates reflect market expectations, competition and individual providers' funding needs. At different points in the interest-rate cycle, an easy-access account may even offer a higher headline rate than some fixed terms.

Easy access |
Notice account |
Fixed-rate bond |
| Access | Normally immediate | After notice period | Typically none until maturity |
| Rate type | Variable | Variable | Fixed for the full term |
| Rate certainty | None | None | Guaranteed |
| Further deposits | Usually permitted, subject to account terms | Often permitted, subject to account terms | Usually not after funding window closes |
| Early exit | Withdraw anytime | Possible with penalty on some accounts | Usually restricted; rules vary by provider |
The rate on a fixed-rate bond cannot be changed by the provider during the term. If Bank Rate falls significantly, your bond continues paying the original rate. If Bank Rate rises, the rate on your existing bond does not increase.
What to watch out for
No access during the term. For most fixed-rate bonds, the money is genuinely unavailable until maturity. (Source: Uswitch, June 2026.)
The funding window closes quickly. Once the short funding period closes, you cannot add money to the bond. Check the funding deadline and arrange any intended deposits within the permitted window.
How interest is credited matters. If interest is added to the bond balance and earns further interest, returns compound. If interest is paid away to another account, it does not remain in the bond. Check whether the quoted AER assumes interest is retained.
Maturity rollover. If you do not respond to your provider's maturity notice, your money may be moved automatically. Set a reminder for 30 days before your maturity date.
Tax on interest. Interest outside an ISA may be subject to UK income tax, depending on your circumstances and available allowances. The tax year in which interest is treated as arising can depend on the account terms and when the interest is credited or made available to you. With multi-year fixed accounts, do not assume that all interest is necessarily taxable only in the maturity year. Check the provider's interest terms and HMRC guidance if the timing could affect your tax position. (Source: HMRC.)
FSCS protection applies up to £120,000 per eligible person per authorised firm. Different banking brands can share the same banking authorisation, so protection may be combined across them.
Why people use fixed-rate bonds
Fixed-rate bonds are often used when someone has money they do not expect to access during a defined period and values certainty about the interest rate during that term.
Because access is normally restricted during the term, fixed-rate bonds do not provide the immediate access generally associated with money held for unexpected expenses. Some people hold a separate easy access account alongside a fixed-rate bond for that purpose.

What is a fixed-rate bond?
A fixed-rate bond — also commonly called a fixed-term deposit or fixed-rate savings account — is a savings account that pays a guaranteed interest rate for a set term, typically one to five years. You deposit money at the start of the term and cannot normally access it until the term ends. They are not the same as government bonds or corporate bonds traded on financial markets. (Source: Raisin UK; money.co.uk.)
Can I withdraw money from a fixed-rate bond early?
Most fixed-rate bonds do not permit early withdrawals. Some providers allow early closure with a penalty — typically the loss of a significant number of days' interest. Others do not permit early access at all. Rules vary by provider — check the specific account terms before opening.
What happens when a fixed-rate bond matures?
The provider will typically contact you before maturity to ask what you want to do. Options usually include withdrawing to your bank account, rolling into a new account, or moving elsewhere. What happens if you do not respond varies by provider — check the maturity terms before opening, and set a reminder for 30 days before the date. (Source: money.co.uk.)
Are fixed-rate bonds FSCS protected?
Yes — at UK-authorised banks and building societies, deposits are protected by the FSCS up to £120,000 per eligible person per authorised firm. Different banking brands can share the same banking authorisation, which can affect the combined level of protection.
Do fixed-rate bonds always pay more than easy access accounts?
No. There is no fixed rule that longer-term bonds pay higher rates than shorter terms. Rates reflect market expectations, competition and providers' funding needs. At different points in the interest-rate cycle, easy-access accounts may offer higher headline rates than some fixed terms.
How is interest taxed on a fixed-rate bond?
Interest outside an ISA may be subject to UK income tax, depending on your circumstances and available allowances. The tax year in which interest is treated as arising depends on the account terms and when interest is credited or made available. Do not assume that all interest on a multi-year bond is taxable only in the maturity year. Check HMRC guidance or speak to a tax adviser if the timing could affect your position. (Source: HMRC.)
