*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.
T37H is the UK Treasury gilt "4 5/8% Green Gilt 2037", paying a 4.625% annual coupon and redeeming at par (£100) on 7 March 2037 — about 10.7 years away. At its 8 Jun 2026 closing price of £96.10 the gross redemption yield is 5.110%. Trading below par, part of its return is a CGT-exempt capital gain to maturity (£390 per £10,000 nominal), so its net yield holds up better after tax than its coupon alone would suggest — a 45% taxpayer keeps 2.98% net.
