ISAs vs Fixed-Rate Bonds

You may have come across the terms ‘ISAs’ and ‘Bonds’ when exploring what savings options are available. But do you know how they differ? 

Choosing the right savings product is important, and what is right for you will depend on your financial goals, how you want to save, and your personal situation. When comparing these accounts, you may wonder what the differences between a bond and an ISA are, and whether it’s possible to have both at the same time.

In this guide, we’ll explain what fixed-rate bonds and ISAs are, highlight the differences between them, and share key points to think about when opening either.

What is an ISA?

An ISA, or Individual Savings Account, is a tax-efficient savings account available to UK residents. Generally speaking ISAs allow you to save or invest up to a set annual allowance (£20,000), with any interest, dividends, or capital gains completely free from tax.

There are several types of ISA, including:

• Cash ISA: Works more like a standard savings account, your money is held in cash with no investment risk, and any interest earned is tax-free.
• Stocks and Shares ISA: Lets you invest in a range of assets such as stocks, bonds, and funds. Any returns are free from tax, but the value of your investments can go up as well as down (capital at risk).
• Lifetime ISA: Designed for first-time buyers, deposit up to £4,000 per year and receive a 25% government bonus. Available as cash or stocks & shares, but access is restricted until you buy your first home or turn 60.
• Innovative Finance ISA: Earn tax-free returns by lending your money through peer-to-peer lending platforms.

As outlined each ISA type serves a different purpose, and features such as interest rates and access terms will vary by product and provider, but they all share the benefit of tax-efficient growth within your annual ISA allowance.

What is a Fixed-Rate Bond?

A fixed-rate bond is a savings account where you deposit a lump sum for a set period, in return for a guaranteed interest rate. Because the rate and term are agreed upfront, you'll know exactly how much interest you'll earn by the end of the term.

Unlike most ISAs, fixed-rate bonds cannot typically be accessed until maturity without a penalty, meaning your money is locked away for the duration of the term. This makes them more restrictive than a standard ISA, but the benefit is a guaranteed interest rate that can be more competitive than easy-access alternatives.

What is the difference between a fixed-rate bond and an ISA?

The main differences come down to tax, access, and limits. ISAs allow tax-free growth, while interest from fixed-rate bonds may be taxable (depending on your Personal Savings Allowance). 

Fixed-rate bonds lock your money away for a fixed term, whereas ISAs can offer more ease of access depending on the individual accounts terms. 

There is also a difference in how much you can save. Most ISAs have an annual allowance of £20,000, whereas fixed-rate bonds tend to have larger deposit limits, making them a potentially better option if you are looking to save a larger sum.

In simple terms, ISAs can be suited to those looking for tax efficiency and accessibility, while fixed-rate bonds may appeal if you’re willing to lock away a more substantial sum for a fixed return.

Can I withdraw money from a fixed-rate bond? 

Early withdrawals or closing a fixed-rate bond before maturity will typically incur a penalty, though the terms will vary by provider. It is important to review the terms and conditions carefully before committing, and to ensure you have an accessible emergency fund to reduce the need to withdraw early.

If you hold a bond with Unity Mutual, the product is designed to run until maturity, but you can withdraw your money before the end of the bond’s fixed term if necessary. You will receive your initial investment back, however, an early withdrawal significantly reduces the interest you would receive. 

Can I transfer my ISA?

Yes, you can usually transfer your ISA*, and doing so can be a way to access better interest rates or choose different investment options. It is important to use the official transfer process rather than withdrawing the money yourself, as this ensures your existing savings retain their tax-free status and your current year's ISA allowance remains unaffected. Different ISAs can come with their own terms and conditions which may result in unexpected fees or changes in growth, so it's important to look through the product details carefully before committing to a transfer.

*There are some restrictions, for example, you cannot transfer a Lifetime ISA into another ISA type, such as a Cash or Stocks and Shares ISA, as this would trigger the 25% government withdrawal penalty.

Can I have a fixed-rate bond and an ISA? 

It is possible to hold both ISAs and fixed-rate bonds at the same time, and the two can complement each other well as part of a broader savings strategy.

There is no limit on the number of fixed-rate bonds you can hold, provided you stay within each provider's maximum deposit limit. 

Similarly, you can hold multiple ISAs of the same or different types, though you can only contribute to one Lifetime ISA, and your total contributions across all ISAs cannot exceed the annual allowance of £20,000.

Is a fixed-rate bond better than an ISA?

Whether a fixed-rate bond is “better” than an ISA depends on your financial goals, how long you plan to save, and your tax situation. They serve different purposes, so one isn’t automatically better than the other.

Here are a few key benefits of both:

Fixed-rate bond benefits

• Guaranteed returns: You'll know exactly how much interest you’ll earn if you leave your money untouched for the full term.
• Low-medium risk: Fixed-rate bonds are generally considered lower risk investments compared to investing in stocks and shares as long as you keep the bond to maturity.
• Larger deposits allowed: Many bonds have higher maximum deposits than the annual ISA allowance, letting you invest more in one place at once.

ISA benefits

• Tax-free growth: Any interest or investment growth inside an ISA is free from Income Tax or Capital Gains Tax.
• Variety of ISA options: With options ranging from cash savings and stocks and shares, to the Lifetime ISA designed for first home purchases, ISAs cater to a wide range of savings and financial goals.
• Ease of access: Depending on the specific product terms, ISAs can generally be more accessible than fixed-rate bonds. There are some ISAs with fixed-terms or withdrawal criteria, so it's always important to review the terms and conditions.

Now that you have a better understanding of both products, the following section walks you through how to apply for an ISA or fixed-rate bond.
