Best Stocks and Shares ISAs in October 2026

A stocks and shares ISA is one of the easiest ways to invest without handing a slice of your returns to the taxman. You can put in up to £20,000 a year, and growth and dividends are tax-free. But with so many providers, picking one can feel like a faff.
Below are six well-known options, with what each costs, who it suits and what to watch out for. We’ve used only the providers’ own published information, so you’re not relying on guesswork.
What’s New for ISAs? (Worth Knowing in October 2026)
The £20,000 overall ISA allowance stays put. But from 6 April 2027, under-65s will only be able to put £12,000 a year into cash ISAs, and won’t be able to move money from a Stocks and Shares ISA into a cash ISA.
Interest on cash held inside a Stocks and Shares ISA is also due to be taxed at 22%, though growth, dividends and investment interest stay tax-free. Some details are still subject to government guidance. The Autumn Budget on 28 October is worth watching too.
What to Look for in a Stocks and Shares ISA
Focus on four things: fees (platform charge, trading costs and currency conversion), investment range (can you buy what you actually want?), ease of use (a clear app helps beginners), and protection (look for FCA regulation and FSCS cover, which protects up to £85,000 if a firm fails, though not if markets fall).
The 6 Best Stocks and Shares ISAs
1. Trading 212: best for low-cost DIY investing
What it is: an app-based ISA provided by Trading 212 UK Ltd (FCA firm reference 609146).
Why it stands out: commission is free, there’s no custody or ISA fee, and the minimum deposit is £1. The only fee it charges on ISAs is a 0.15% FX fee when you trade in another currency. It also offers Pies (ready-made or custom portfolios) and a free demo account.
Watch out for: no managed ISA, so you’re doing the choosing. Stamp duty of 0.5% applies on UK-listed shares.
2. InvestEngine: best for ETF fans
What it is: an ETF-focused platform (FCA FRN 801128, FSCS cover up to £85,000).
Why it stands out: zero platform fees, free commission and free currency conversion on its DIY ISA, with fractional investing.
Watch out for: the ETFs themselves have running costs, which aren’t covered by the zero platform fee. It’s ETF-focused, so it’s not for single-share stock pickers.
3. Freetrade: best for choice of plans
What it is: a UK app with three plans: Basic (£0), Standard (£4.99 a month on annual billing, or £5.99 monthly) and Plus (£9.99 or £11.99).
Why it stands out: commission is £0 on every plan, with 8,600+ stocks, ETFs, funds and investment trusts. Higher plans cut the FX fee from 0.99% to 0.59% to 0.39% and pay interest on uninvested cash (1% to 3.5% AER on capped balances).
Watch out for: paid plans only make sense if you’ll use the perks. Freetrade says other charges may apply.
4. AJ Bell: best for regular investors who want choice
What it is: a long-established UK platform.
Why it stands out: the funds account charge is 0.25% up to £250,000, while the shares account charge is 0.25% capped at £3.50 a month. Fund dealing is £1.50 a deal, shares £5 (or £3.50 if you trade often), and monthly investments from £25 carry no dealing charge.
Watch out for: dealing fees add up if you trade often, and international dealing costs extra.
5. Vanguard Investor: best for hands-off investing
What it is: the UK arm of the giant fund manager, offering a self-managed ISA (85+ funds) and a Managed ISA that picks and manages a portfolio for you.
Why it stands out: account fee is £4 a month under £32,000, then 0.15% a year capped at £375 (the Managed ISA charges 0.15% plus a 0.20% management fee). There are no fees for trades, transfers or withdrawals.
Watch out for: a minimum of £500 as a lump sum or £100 a month, and fund costs of 0.06% to 0.79% a year on the self-managed service.
6. Hargreaves Lansdown: best for research and support
What it is: one of the UK’s best-known investment platforms.
Why it stands out: account opening is free, with no exit or transfer-out fees, and cash is free to hold. The fund account charge is 0.35% up to £250,000, while shares and ETFs cost 0.35% capped at £12.50 a month. Regular monthly Direct Debit investing has no dealing charge.
Watch out for: one-off share trades are £6.95 (or £3.95 if you make 20 or more a month), fund trades £1.95, and 0.5% stamp duty applies on UK shares. It’s usually dearer than the app-based rivals.
Which One Should You Choose?
- Cheapest and simple: Trading 212 or InvestEngine.
- Hands-off: Vanguard’s Managed ISA.
- Regular monthly investing: AJ Bell or Hargreaves Lansdown, where monthly investing has no dealing charge.
- Want extras like cash interest and priority support: Freetrade Standard or Plus.
What to Do Next
- Pick your style: DIY, or managed for you.
- Compare current fees: fees can change, so check the provider’s fees page first.
- Check protection: confirm FCA regulation and FSCS cover.
- Open your ISA and start small: a regular monthly amount beats waiting for the “perfect” moment.
- Use your allowance by 5 April: the £20,000 limit resets each tax year and doesn’t roll over.
