Frequently asked questions

Q. What is a Stocks & Shares ISA?
A. A tax-efficient wrapper that lets UK investors buy shares, funds and ETFs without paying income or capital gains tax on returns up to the annual ISA allowance.

Q. How does a SIPP differ from an ISA?
A. A Self-Invested Personal Pension (SIPP) is a retirement account with tax relief on contributions, but funds are typically locked until age 55+. ISAs are more flexible with no withdrawal age limit.

Q. Are there trading fees?
A. Platforms like AJ Bell charge a platform fee and per-trade costs, whereas Freetrade and eToro offer zero-commission on stocks/ETFs. Always compare fees for your trade frequency and portfolio size.

Q. Can I buy fractional shares?
A. Yes – Freetrade, Trading 212 and eToro all support fractional share purchases from as little as £1, helping you diversify with smaller sums.

Q. Is customer support available?
A. AJ Bell and Hargreaves Lansdown are renowned for award-winning phone and online support. Freetrade, eToro and other app-first platforms rely more on in-app chat and FAQs.

Q. Can I transfer existing ISAs?
A. Most providers, including AJ Bell, Hargreaves Lansdown and Interactive Investor, offer free ISA transfers—though share-transfer fees may apply. Check the transfer process and timelines.

Q. Do these platforms offer ready-made portfolios?
A. Yes – Hargreaves Lansdown, Interactive Investor and InvestEngine provide model portfolios or Smart Portfolios to automate diversification based on your risk level.

Q. Which platform is best for beginners?
A. Freetrade and eToro excel with simple, intuitive apps and low or zero commission. AJ Bell offers excellent guidance, while Hargreaves Lansdown delivers comprehensive research if you want more hand-holding.
