*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.
T51A is the UK Treasury gilt "1 1/4% Treasury Gilt 2051", paying a 1.25% annual coupon and redeeming at par (£100) on 31 July 2051 — about 25.1 years away. At its 8 Jun 2026 closing price of £41.40 the gross redemption yield is 5.658%. Because the coupon is low and the price is well below par, most of the return comes as the tax-free pull to par (a £5,860 capital gain per £10,000 nominal, exempt from CGT) rather than as taxable coupon income. That makes it unusually efficient for higher- and additional-rate taxpayers: an additional-rate (45%) payer keeps a net yield of 4.70% — to match that after tax, a fully-taxable savings account or bond would need to pay about 8.54% gross.
