Best Brokers for UK Investors Buying UK Stocks
UK investors buying UK-listed stocks face a specific cost structure: 0.5% Stamp Duty Reserve Tax (SDRT) on purchases of UK-listed shares, plus brokerage commission. For passive UK equity exposure, FTSE 100/All-Share ETFs (ISF, VUKE, CUKX) are exempt from SDRT and are the most cost-efficient route. For individual UK shares, Hargreaves Lansdown, AJ Bell, and Interactive Investor are the dominant platforms. For cost-minimisers: Freetrade offers zero-commission dealing on UK shares (no SDRT exemption), and Trading 212 similarly. ISA and SIPP wrappers are essential for UK equity investing — they eliminate capital gains tax and dividend income tax on returns within the wrapper.

About UK Stocks: what UK investors need to know
Why invest here
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.
Key risk
GBP currency risk; UK dividend withholding (none for most — UK doesn't withhold on dividends)

Regulation for UK investors
FCA-regulated UK brokers required (HL, AJ Bell, Interactive Investor, Freetrade, Trading 212). 0.5% SDRT on UK share purchases (exempt for ETFs and AIM stocks). CGT annual exempt amount £3,000 from 2024/25. Dividend allowance £500 from 2024/25. ISA wrapper (£20,000/year) and SIPP eliminate all CGT and income tax on returns. Bed-and-ISA strategy allows moving existing holdings into ISA wrapper.
Tax treatment for UK investors in UK stocks
CGT on UK shares: 18% (basic rate) or 24% (higher rate) from October 2024. Dividend income above £500 annual allowance taxed at 8.75% (basic), 33.75% (higher), or 39.35% (additional). Inside an ISA or SIPP: all returns tax-free. 0.5% SDRT on purchases adds to cost basis but is not recoverable. No withholding on UK dividends paid to UK residents.
