Gilt Funds vs Direct Gilts: Which Is Best?

Key Takeaways

  • Direct gilts offer maturity certainty and CGT exemption — ideal for higher-rate taxpayers investing outside ISAs.
  • Gilt funds and ETFs provide diversification, convenience, and low minimum investments, with ongoing charges as low as 0.07%.
  • Within an ISA or SIPP, the tax differences between direct gilts and funds disappear entirely — both are completely tax-free.
  • In a falling rate environment, gilt funds may outperform as the entire portfolio benefits from rising prices across maturities.
  • A combined approach — direct gilts for specific goals plus a gilt ETF for general allocation — offers the best of both worlds.

When investing in UK government bonds, one of the first decisions you'll face is whether to buy individual gilts directly or invest through a gilt fund or ETF. Both approaches give you exposure to the gilt market, but they differ significantly in terms of cost, flexibility, tax treatment, and the certainty of returns.

With UK long-term gilt yields sitting at around 4.45% as of January 2026 and the Bank of England expected to continue easing monetary policy, interest in gilts has surged among retail investors. Understanding the trade-offs between direct gilt ownership and fund-based exposure is essential for making the right choice for your circumstances.

This comparison breaks down the key differences — from maturity guarantees and income predictability to tax efficiency and cost — so you can decide which approach best fits your investment goals.

How Direct Gilts Work

When you buy an individual gilt, you own a specific UK government bond with a defined coupon rate and maturity date. For example, purchasing the "Treasury 4.25% 2034" gilt means you'll receive 4.25% of the nominal value annually (paid in two semi-annual instalments) and get £100 per unit back when the bond matures in 2034.

This predictability is the primary advantage of direct gilt ownership. If you buy and hold to maturity, you know exactly what income you'll receive and when you'll get your capital back. The only uncertainty is reinvestment risk — what yields will be available when the gilt matures and you need to reinvest.

Direct gilts are available through investment platforms like Hargreaves Lansdown, AJ Bell, or Interactive Investor, as well as directly through the Debt Management Office (DMO). Typical dealing charges are £5–£12 per trade through platforms. There are no ongoing management fees since you own the bond outright.

The main limitation is that building a diversified portfolio of individual gilts requires more capital and research. If you want exposure across multiple maturities and coupon rates, you'll need to make several separate purchases, each incurring dealing costs.

How Gilt Funds and ETFs Work

Gilt funds pool money from many investors to buy a diversified portfolio of gilts. The fund manager — or in the case of index trackers, an algorithm — selects which gilts to hold and manages the portfolio on your behalf.

The most popular options include index-tracking ETFs like the iShares Core UK Gilts UCITS ETF (IGLT) with an ongoing charge of just 0.07%, and tracker funds like the Vanguard UK Government Bond Index Fund at 0.12%. These provide exposure to the entire conventional gilt market in a single investment.

Specialised gilt ETFs offer targeted exposure: the iShares UK Gilts 0-5yr ETF (IGLS) focuses on short-duration gilts for lower interest rate risk, while index-linked gilt funds provide inflation protection.

The key difference from direct gilts is that a fund never matures. It continually buys and sells gilts to track its benchmark index. This means you never reach a point where you receive a guaranteed par value back — instead, your return depends on the fund's net asset value when you sell. This lack of a maturity date is the single most important distinction between the two approaches.

Which Should You Choose?

Conclusion

The choice between gilt funds and direct gilts is not about which is objectively better — it's about which better matches your circumstances. Direct gilts shine for tax efficiency outside of ISAs and for investors who want maturity certainty. Gilt funds and ETFs win on convenience, diversification, and accessibility for smaller investors.

For most investors using an ISA or SIPP, gilt ETFs like iShares IGLT at just 0.07% ongoing charge are hard to beat for simplicity and cost. But for higher-rate taxpayers with larger portfolios investing outside tax wrappers, the CGT exemption on direct gilts can deliver meaningfully better after-tax returns. Whichever route you choose, gilts at current yields above 4% represent genuine value in a portfolio — offering safety, income, and diversification from equities.
