Frequently Asked Questions

The best platform depends on your goals. For a Stocks & Shares ISA, Trading 212 is our top pick for beginners due to its zero-commission model. For larger portfolios, Interactive Investor's flat-fee structure becomes more cost-effective. For ETF-focused investing, InvestEngine offers a genuinely zero-cost DIY ISA. See our full best investment platforms UK guide.
Kraken is our top overall pick for UK investors due to its FCA registration and strong security record. Binance offers the lowest fees and widest coin selection. MEXC is best for altcoin trading. You can compare all 10 in our full crypto exchange comparison.
A Stocks & Shares ISA is a tax-efficient investment account available to UK residents. You can invest up to £20,000 per tax year with no Income Tax or Capital Gains Tax on any returns. It can hold shares, ETFs, funds and other assets. Compare options on our ISA platforms comparison page.
No. Cryptocurrency is excluded from FSCS protection, which covers UK bank and savings accounts up to £85,000. FCA registration means an exchange has passed anti-money laundering checks — it does not protect your investment if an exchange fails.
Yes. HMRC treats crypto as a capital asset. If you sell or swap crypto for more than you paid, you may owe Capital Gains Tax. The annual CGT allowance for 2025–26 is £3,000. Gains above this are taxed at 18% (basic rate) or 24% (higher rate). Speak to a qualified accountant for personal tax advice.
We may earn affiliate commission when you open an account through a link on this site. This does not influence our ratings — platforms are ranked on published criteria including fees, security, features, and usability. Our affiliate disclosure and rating methodology explain this in full.
