Fixed Income Bonds UK: Are They Safe? Gilts vs Corporate Bonds vs Bond Funds Explained
By Alpesh Patel OBE, hedge fund manager and author
Fixed income bonds are lower risk than shares, but they are not risk free. UK government bonds (gilts) held to maturity are about as safe as investing gets in sterling, because the government has never missed a payment.
Corporate bonds pay more because the company could default. Bond funds never "mature", so their value moves up and down with interest rates, and some lost over a third of their value in 2022. "Safe" depends on which type you buy, how long it runs for, and whether you can hold it to the end.
People search for "fixed income bonds" meaning two quite different things. One is a bank's fixed rate bond, which is really a savings account that locks your cash away for a set term. The other is an investment bond such as a gilt or corporate bond, which you buy and can sell on the market. They behave very differently, so it's worth getting this straight first.
What is a fixed income bond?
A bond is a loan. You lend money to a government or company, it pays you interest (the "coupon") at regular intervals, and it promises to pay back the original amount (the "face value") on a set date (the "maturity").
It's called fixed income because the coupon is usually fixed when the bond is issued. If you buy a £100 gilt paying 4% a year, you get £4 a year until maturity, then your £100 back.
The catch is that the price of the bond can change before maturity. If you sell early, you get the market price, which could be more or less than you paid.
Are fixed income bonds safe?
It depends on three risks:
Default risk. Can the borrower pay you back? The UK government can print the currency it borrows in, so gilts carry very little default risk. A company can go bust, which is why corporate bonds pay a higher rate.
Interest rate risk. When interest rates rise, existing bonds with lower coupons become less attractive, so their prices fall. The longer a bond has left to run, the bigger the fall.
Inflation risk. A fixed £4 a year buys less as prices rise. Over long periods inflation can quietly eat your real return.
2022 showed this clearly. Bonds were sold as "the safe part of a portfolio", yet when interest rates rose fast, some long-dated gilt funds fell by more than a third. Nobody defaulted. The prices simply adjusted to higher rates. Investors who held individual gilts to maturity still got their money back; investors in funds who needed to sell did not.
Bank fixed rate bonds vs investment bonds
Bank fixed rate bond | Gilt | Corporate bond | Bond fund or ETF | |
|---|---|---|---|---|
What it is | Savings account locked for a term | Loan to the UK government | Loan to a company | A basket of many bonds |
Can the value fall? | No | Yes, if sold before maturity | Yes, and the company can default | Yes, at any time |
Protection | FSCS up to £120,000 per person per bank | Backed by the UK government | None if the company fails | Depends on the bonds held |
Can you get out early? | Usually not, or with a penalty | Yes, sell on the market | Yes, but can be less liquid | Yes, sell any dealing day |
Has a fixed end date? | Yes | Yes | Yes | No |
The FSCS deposit protection limit rose to £120,000 per person, per authorised bank or building society, from 1 December 2025. It covers bank fixed rate bonds, not gilts, corporate bonds or bond funds.
If you want certainty that you get back exactly what you put in, a bank fixed rate bond within the FSCS limit is the simplest option. If you want to be able to sell and possibly make a capital gain, you're in investment bond territory. I compare the two in more detail in bond funds vs 12-month fixed deposits.
Gilts vs corporate bonds in the UK
Gilts are issued by the UK Debt Management Office. Two features make them interesting for UK investors:
Capital gains on gilts are exempt from Capital Gains Tax for individuals. The coupon is taxed as income unless you hold it in an ISA or SIPP.
Low-coupon gilts bought below face value can therefore deliver much of their return as a tax-free gain at maturity, which matters for higher-rate taxpayers investing outside a wrapper.
Corporate bonds pay a higher yield to compensate for default risk. Credit rating agencies grade them. "Investment grade" means BBB- or above; anything lower is "high yield", a polite name for junk. The extra yield over gilts is called the credit spread. When the economy weakens, spreads widen and corporate bond prices fall, often at the same time as shares.
For reference, the 10-year gilt yield was around 5.4% in early October 2026 (Investing.com). Check today's figure on your platform before acting, because yields move daily.
How to invest in fixed income bonds
Decide what the money is for and when you need it. Money needed in two years should not sit in a 20-year bond.
Pick individual bonds or a fund. Individual gilts let you hold to maturity and know your return. Funds give diversification but have no end date.
Match the maturity to your timeline. Shorter bonds move less when rates change. A rough rule: a bond's price moves by about its "duration" in percent for every 1% change in interest rates.
Check the yield to maturity, not the coupon. A 1% coupon gilt bought at £90 has a very different return from a 5% coupon gilt bought at £105.
Use your wrappers. Hold higher-coupon bonds inside an ISA or SIPP so the interest isn't taxed.
Compare costs. Platform fees and fund charges come straight out of a bond's modest return.
Most UK platforms let you buy gilts and bond ETFs. If you're choosing one, my comparison of Interactive Brokers vs Hargreaves Lansdown covers costs and features.
What are low risk bonds in the UK?
The lowest risk bonds for a UK investor are short-dated gilts: little default risk and little interest rate risk because they mature soon. Next come short-dated investment grade corporate bonds and short-term gilt funds. Long-dated bonds and high yield bonds are not low risk, whatever the label says.
I go through the wider menu, including money market funds and cash, in low-risk fixed income options for UK investors.

Where bonds fit in a portfolio
Bonds can reduce how much a portfolio swings, provide income and give you dry powder when shares fall. But they won't grow your wealth the way good companies can over 10 or 20 years. The danger for many UK investors isn't owning bonds; it's owning them by default, in a fund they've never looked at, without knowing why. That's exactly what I found in Scottish Widows' CS8 pension portfolios, where fees and "bond drag" held back returns.
A process tells you how much to hold in bonds, which ones, and when to change the mix. Without one, you're guessing. To measure whether your mix is earning its keep for the risk taken, see Sharpe vs Sortino vs Calmar ratio.
Frequently asked questions
Can you lose money on fixed income bonds?
Yes. If you sell a bond before maturity after interest rates have risen, you can get back less than you paid. If a company issuer defaults, you can lose some or all of your money. A bank fixed rate bond within the FSCS limit won't fall in value.
Are gilts safer than corporate bonds?
Yes, in terms of default risk. The UK government has never missed a gilt interest or capital payment. Both still carry interest rate risk if you sell early.
Are bond funds safe?
They are lower risk than equity funds, but they have no maturity date, so you can't simply wait to get your money back. Their value rises and falls with interest rates every day.
Are gilts tax free?
Capital gains on gilts are free of Capital Gains Tax for individuals. The interest is taxable as income unless held in an ISA or SIPP.
What's better, bonds or a savings account?
For money you need within a year or two and want guaranteed, a savings account or bank fixed rate bond within the FSCS limit is simpler. Investment bonds can make sense when you want to lock in a yield for longer or hold gilts for their tax treatment.
