Fixed-rate savings bonds — sometimes called fixed-rate bonds or fixed-term deposits — offer some of the highest interest rates available to UK savers right now, but they come with an important trade-off: you cannot access your money until the fixed term ends.

With the Bank of England base rate expected to fall further through 2026, now could actually be a smart time to lock in a fixed rate before rates drop any lower.
How fixed-rate bonds work
You deposit a lump sum for a set period — usually one, two, three or five years — and the bank pays you a guaranteed interest rate for the full term. At the end of the term your original deposit plus all interest is returned to you.
Unlike easy-access accounts, you generally cannot make withdrawals during the fixed term. Some providers allow early closure in exceptional circumstances but will charge a penalty, typically equivalent to several months' interest.
Current rates in 2026
One-year fixed-rate bonds are currently paying up to around 4.8% AER, with two-year fixes slightly lower at around 4.5% AER. Five-year bonds are lower still, reflecting market expectations that interest rates will be lower in the longer term.
These rates comfortably beat inflation and easy-access accounts at most banks, making them attractive for money you are confident you will not need in the short term.
Who should consider a fixed-rate bond?
Fixed-rate bonds are well suited to savers who have a specific financial goal — a home purchase, a wedding, a car — planned for a known future date. They are also useful for emergency fund overflow: once you have a sufficient easy-access emergency fund, surplus savings can be locked away in a fixed bond for a better return.
They are not suitable for your emergency fund itself, as you need immediate access to that money by definition.
FSCS protection
Make sure any fixed-rate bond you open is covered by the Financial Services Compensation Scheme, which protects up to £85,000 per person per authorised institution. If you have more than £85,000 to save, spread it across multiple providers to ensure full protection.
Bottom line
Fixed-rate bonds offer the best guaranteed returns available to UK savers right now. If you have money you definitely will not need for one to five years, locking it into a competitive fixed rate makes excellent financial sense — particularly before the base rate falls further.
