The UK Treasury 4.25% 2055 is a conventional gilt with a 4.25% coupon, maturing on 7 Dec 2055 — roughly 29.5 years from now. At the latest market price it is a long-dated (15+ years) holding currently trading below par (at a discount).
Based on a clean price of about £81.71 per £100 nominal, this gilt offers a running yield of 5.20% and a yield to maturity of 5.51%. The running yield reflects the income return from coupons alone, while the yield to maturity also accounts for the capital gain if you hold to redemption.
Because capital gains on gilts are exempt from UK Capital Gains Tax, a gilt priced below par can be particularly tax-efficient: the pull-to-par capital gain is tax-free, and only the coupon income is taxable. The calculator below shows both gross and net (after-tax) returns.
