*Grossed-up = the gross yield a fully-taxable savings account or bond would need to match this gilt's net yield, at that tax rate. Gilt coupons are taxed as income; the capital gain to par is exempt from CGT. Figures don't include your Personal Savings Allowance, so they're conservative. How we calculate this.
T31 is the UK Treasury gilt "4% Treasury Gilt 2031", paying a 4% annual coupon and redeeming at par (£100) on 22 October 2031 — about 5.4 years away. At its 8 Jun 2026 closing price of £97.43 the gross redemption yield is 4.533%. Trading below par, part of its return is a CGT-exempt capital gain to maturity (£257 per £10,000 nominal), so its net yield holds up better after tax than its coupon alone would suggest — a 45% taxpayer keeps 2.71% net.
