A fixed rate savings account can be one of the most rewarding places to put money you don’t need to touch for a defined period. You lock in a rate, leave your money alone, and collect your interest at the end. The challenge is knowing which accounts are genuinely worth committing to — and avoiding the pitfalls that catch out even experienced savers.
This guide explains what to look for when comparing fixed rate accounts, the key questions to ask before you commit, and how to get the most from your money. For current best-buy rates, we recommend checking Moneyfacts or MoneySavingExpert alongside this guide as rates move frequently.
What is a fixed rate savings account?
A fixed rate savings account — sometimes called a fixed rate bond — pays a guaranteed interest rate in exchange for locking your money away for a set term, typically between one and five years. The rate doesn’t change during that period, regardless of what happens to the Bank of England base rate.
If you’re new to fixed rate accounts, our full guide to how fixed rate savings accounts work covers everything you need to know before opening one.
What makes a good fixed rate savings account?
The AER
The Annual Equivalent Rate (AER) is the standard measure for comparing savings rates fairly. It accounts for how often interest is compounded, making it the most accurate figure to use when comparing accounts across different providers and terms. Always compare AER, not gross rate.
The fixed term
Fixed rate accounts typically come in one, two, three and five year terms. Longer terms don’t always offer better rates — it depends on where the market expects interest rates to go. Check rates across all available terms before committing, as the best rate isn’t always on the longest term.
Early access penalties
Most fixed rate accounts don’t allow early withdrawals at all — your money is locked away until the term ends. Some providers do allow early access but charge a significant penalty, typically equivalent to several months of interest. Always check the early access policy before opening, and only fix money you’re genuinely confident you won’t need.
FSCS protection
The Financial Services Compensation Scheme (FSCS) protects up to £85,000 per person, per banking licence. Because your money will be inaccessible for the duration of the term, it’s especially important to confirm FSCS protection before opening a fixed rate account. Also check whether your provider shares a banking licence with another institution you already save with — if so, the £85,000 limit applies across both.
Minimum and maximum deposit
Fixed rate accounts typically require a minimum lump sum — often £500 to £1,000, though some start from £1. Maximum deposit limits also apply on some accounts, particularly those offered by smaller providers or via savings platforms.
Interest payment frequency
Some fixed rate accounts pay interest monthly — useful if you want a regular income from your savings. Others pay annually or at maturity. If monthly income matters to you, check this before applying as not all providers offer it.
What happens at maturity
When your fixed term ends, providers typically move your money into an easy access account or a lower-rate holding account automatically. Always check what happens at maturity and set a reminder to act — don’t let your money sit in a low-rate holding account when better options are available.
One year vs two year vs five year — which term is best?
The right term depends on your personal circumstances and your view on the interest rate environment.
One year fixed rate accounts are the most popular choice. They offer a meaningfully better rate than easy access without tying your money up for too long, and give you the flexibility to reassess in twelve months.
Two and three year accounts suit savers who are confident they won’t need the money and want to lock in a competitive rate before any potential cuts. If the Bank of England is expected to cut rates, fixing for longer can protect your return.
Five year accounts are best for money you’re genuinely setting aside for the long term. Five-year rates aren’t always the highest on offer — compare carefully across terms before committing.
Savings platforms — a different way to access fixed rate accounts
Savings platforms such as Raisin UK and Flagstone allow you to access fixed rate accounts from multiple banks through a single login. Rather than opening separate accounts with each provider, you deposit once and allocate funds across different banks and terms from one dashboard.
This is particularly useful if you have more than £85,000 to save — a platform makes it easier to spread your money across multiple banking licences to maximise FSCS protection.
What to watch out for
Locking in at the wrong time. If interest rates rise after you’ve fixed, you could find yourself earning less than newer accounts offer. One year terms reduce this risk — you’re never more than twelve months away from being able to switch.
Not keeping enough accessible. Before fixing any money, make sure you have at least three to six months of living expenses in an easy access savings account. Fixed rate accounts are for surplus savings only — never money you might need urgently.
Shared banking licences. Some providers that appear separate share a banking licence. If you already save with one, check before opening a fixed rate account with another provider in the same group — your FSCS protection may already be partially used.
How much could I earn?

Fixed rate vs easy access vs notice account
| Easy Access | Notice Account | Fixed Rate | |
|---|---|---|---|
| Flexibility | Withdraw anytime | Give notice first | No access until term ends |
| Interest rate | Lower | Middle ground | Higher |
| Rate type | Variable | Variable | Fixed |
| Best for | Emergency fund | Planned savings | Money you won’t need |

Summary
The best fixed rate savings account is the one that pays the highest AER for a term you’re genuinely comfortable committing to — with full FSCS protection and no hidden withdrawal restrictions. Rates change frequently, so always compare across providers and terms before applying. Use our savings calculator to see what different rates mean for your specific balance, and make sure your emergency fund stays in an easy access account before fixing anything.
