Best Brokers for UK Investors in UK Stocks
UK investors can access UK stocks through global online brokers. The FTSE 100 trades at a significant discount to US markets on most valuation metrics and offers higher dividend yields (~3.5% vs ~1.4% for the S&P 500). It is heavily weighted toward energy, mining, financials, and consumer staples — useful diversification away from US tech concentration. Converting GBP to USD via HL costs 1% each way. IBKR charges 0.1%. On a £10,000 investment: HL charges ~£100, IBKR ~£10.
