Best Brokers for UK Investors Buying Bonds and Fixed Income
UK investors accessing bonds have three main routes: (1) UK government gilts via IBKR or HL (zero stamp duty, gilt income taxable as income not CGT); (2) UCITS bond ETFs on LSE — iShares Core UK Gilts UCITS ETF (IGLT, 0.07% TER), Vanguard UK Government Bond Index (VGOV, 0.12% TER), iShares Global Corp Bond UCITS ETF (CORP, 0.20% TER); (3) individual corporate bonds via IBKR or fixed income platforms like Bondsmith or FixedIncomeDirect. For most UK investors, gilts inside an ISA (income tax-free) plus IG corporate bond ETFs provide efficient fixed income exposure. Direct gilt purchases are attractive at current yields (4.5–5% for 5-year gilts) and qualify for CGT-exempt treatment — gilt gains are not subject to CGT.

ISA wrapper: all income and gains tax-free on bond holdings within ISA. SIPP: particularly attractive for bonds given the guaranteed income tax relief on contributions. US Treasuries held by UK residents: 0% US withholding under the US–UK treaty on interest (not dividends).
