Why low-coupon gilts?

When you buy a gilt below its £100 par value, the difference between your purchase price and the £100 redemption value is a capital gain — completely exempt from Capital Gains Tax in the UK. Only the coupon income is taxable. For higher-rate and additional-rate taxpayers, this makes low-coupon gilts an exceptionally efficient way to earn near-risk-free returns.
