UK government bonds, known as gilts, have been paying interest above 4% in 2025, a rate not seen consistently for over a decade. For someone with £10,000 to invest, that could mean £400 a year in interest payments, which is more than most premium dividend stocks are currently yielding. But the story doesn’t end with the coupon — gilt prices have been swinging wildly, and the total return you walk away with depends heavily on when you buy, what maturity you pick, and what the Bank of England does next.

Gilts are essentially loans you make to the UK government. You hand over your money, the government pays you a fixed rate of interest (the coupon) for a set number of years, and then gives your original investment back at the end. They’re considered one of the safest places to park money because the UK government has never defaulted on its debt. But “safe” doesn’t mean “no risk” — especially right now. Yields on 30-year gilts hit levels not seen since the late 1990s in 2025, and the inflation that erodes your purchasing power is still running nearly double the Bank of England’s target. Here’s what you actually need to know.
What the current gilt market actually looks like
The central concept here is yield — the effective return you get on a bond based on its current price, not just its coupon rate. A gilt with a 2% coupon might trade at a discount so that its yield to maturity is actually 4.5%. That’s the number that matters when comparing gilts to savings accounts or stocks.
What I tend to notice is that many people look only at the coupon rate printed on the bond and assume that’s their return. In a market where prices fluctuate daily, the yield to maturity is the honest measure. A gilt trading at a discount can offer a much better deal than one trading at par, even if the coupon looks smaller.
Gilt yields, maturities, and what they mean for your money
The relationship between a gilt’s maturity and its yield is where most of the action happens. Short-term gilts (1–5 years) are more sensitive to Bank of England rate decisions. Long-term gilts (20–30 years) react more to inflation expectations and fiscal credibility. Right now, the gap between them is unusually wide.

| Gilt Maturity | Typical Yield Range (2025) | Main Risk |
|---|---|---|
| 1–5 years (short) | 4.0% – 4.3% | Reinvestment risk if rates fall |
| 10 years (medium) | 4.2% – 4.5% | Interest rate changes |
| 20–30 years (long) | 4.5% – 5.0%+ | Inflation and fiscal policy shocks |
Here’s a concrete scenario. Say you buy a 30-year gilt with a 3% coupon in 2024 for £100. By 2025, market yields on similar gilts have jumped to 5%. If you need to sell that gilt before maturity, its market price will have fallen — potentially to around £70 per £100 face value. That’s a 30% capital loss, wiping out years of interest payments. If you hold to maturity, you get your £100 back, but you’ve been earning 3% while inflation ran at 3.8%. Your real return is negative.
On the other hand, if you buy a 5-year gilt at 4.2% and hold it to maturity, you know exactly what you’ll get. The price volatility is much smaller because the bond is closer to its repayment date. For someone who wants predictable income without the rollercoaster, shorter maturities tend to make more sense right now.
Where investors get tripped up with gilts
Mistaking coupon rate for total return
A gilt might say “4% coupon” on the tin, but if you buy it at a premium (above £100), your actual yield to maturity is lower. Conversely, buying at a discount boosts your yield. Many investors grab the highest coupon without checking the price, then wonder why their return doesn’t match expectations. Always check the yield to maturity, not the coupon rate, when comparing options.
Ignoring the impact of inflation on real returns
UK inflation at 3.8% means a 4.5% gilt yield leaves you with a real return of just 0.7% before tax. For a basic-rate taxpayer, that 4.5% becomes 3.6% after tax — below inflation. You’re effectively losing purchasing power each year. Index-linked gilts adjust for inflation, but their yields are typically lower upfront, and the inflation adjustment is taxable as income. There’s no free lunch.
Selling long-dated gilts before maturity in a rising rate environment
This is the most expensive mistake. If you buy a 30-year gilt and need to sell it two years later when yields have risen, you take a capital loss that can easily exceed all the interest you’ve collected. The longer the maturity, the more sensitive the price is to rate changes. If you can’t commit to holding for the full term, stick to shorter maturities or consider a bond fund that manages duration for you.
Overlooking the supply glut coming in 2026
The UK government is issuing more gilts to fund its spending, while the Bank of England is actively selling off its own gilt holdings (quantitative tightening). More supply with steady or falling demand tends to push prices down and yields up. Morningstar flags this as a key risk for 2026. If you’re buying now, factor in that yields could go higher before they go lower.
How to buy gilts and what to watch for
Buying individual gilts through a broker
You can buy gilts through most UK stockbrokers, including Hargreaves Lansdown, AJ Bell, and Interactive Investor. The process is similar to buying shares: you search for the gilt by its name or ISIN, place a buy order, and pay a dealing fee (typically £5–£12). Gilts trade in increments of £100 face value, but you’ll pay the market price, which can be above or below £100. The interest (coupon) is paid semi-annually into your account. You’ll need a general investment account or a Stocks and Shares ISA to hold them.
Using a gilt fund or ETF instead
If you don’t want to pick individual bonds, a gilt fund or ETF (like the iShares UK Gilts UCITS ETF) does the work for you. The fund holds a basket of gilts and you buy shares in the fund. The trade-off is that you pay an ongoing fee (typically 0.07%–0.25% per year), and the fund’s price fluctuates daily as the underlying bonds are revalued. For most people, a short-dated gilt fund is simpler and more diversified than buying individual bonds.
What to expect from 2026 — the emerging picture
Morningstar’s outlook for 2026 suggests a decent year for UK bond investors, but not without risks. Expected Bank of England rate cuts should boost short-term gilt prices. But political risks — local elections in May, the Spring Statement, and the Autumn Budget — could trigger volatility. The UK government’s bond sales and the Bank of England’s balance sheet reduction mean more supply hitting the market, which could depress prices. If you’re investing for income, locking in current yields on shorter maturities (1–5 years) might be the sweet spot: you get the high rates without taking on the price volatility of long-dated bonds.
Tax treatment of gilt income and gains
Gilt interest is taxed as income, at your marginal rate. For a higher-rate taxpayer, that 4.5% yield becomes 2.7% after tax. Capital gains on gilts are currently tax-free — a significant advantage over corporate bonds or shares. This makes gilts particularly attractive for higher-rate taxpayers who might sell before maturity, because any price appreciation is free of capital gains tax. But remember: if you hold to maturity, you get your principal back with no gain or loss, so the tax advantage only matters if you trade them.

The case for gilts depends on your timeline and tax bracket
Gilts at 4%+ yields are genuinely attractive for income-seeking investors who can hold to maturity and don’t need to worry about short-term price swings. For a basic-rate taxpayer in a Stocks and Shares ISA, that 4% is tax-free and beats most savings accounts. But for a higher-rate taxpayer holding outside an ISA, the after-tax return drops to 2.4% — barely above inflation. The real opportunity right now is probably in short-dated gilts (1–5 years), where you lock in high yields with minimal price risk, while waiting to see whether the Bank of England cuts rates in 2026 as expected.
