Choosing a stocks and shares ISA platform is one of the most consequential financial decisions a UK investor can make. Not because the choice is irreversible (you can transfer), but because platform fees compound against you over decades in exactly the same way that investment returns compound in your favour.
A 0.20% difference in annual platform fees on a £50,000 ISA costs you £100 a year. Over 20 years at 7% average growth, that difference compounds to roughly £4,400 lost to charges you never had to pay. The right platform saves real money. The wrong one quietly erodes it.

This guide covers seven of the most widely used UK stocks and shares ISA platforms in 2026, comparing the top ISA providers and platforms in the UK on fees, fund range and who each one genuinely suits. Every fee figure has been verified directly from each provider’s website. Where platforms have changed their pricing recently (and several have), those changes are reflected here.
- Lowest cost overall: InvestEngine (DIY) and Trading 212 both charge zero platform fees for ETF and share investing
- Best for a wide investment range: AJ Bell offers funds, shares, bonds and trusts at a competitive 0.25% fee, capped at £42/year on shares
- Best for research and guidance: Hargreaves Lansdown, with the widest range and the most comprehensive tools, though at a higher cost
- Best for passive index investing: Vanguard, if you hold £32,000 or more (otherwise the £4/month minimum erodes the value)
- Best for total beginners: AJ Bell Dodl, with a deliberately limited menu and a flat, simple fee
- Watch for in 2027: the Cash ISA allowance cut from £20,000 to £12,000 for under-65s (does not affect stocks and shares ISAs)

📘 What Is a Stocks and Shares ISA?
A stocks and shares ISA is a tax-efficient investment account that allows you to invest in funds, shares, ETFs (exchange-traded funds), bonds and investment trusts, with all growth sheltered from UK tax.
Inside the ISA wrapper, you pay no Capital Gains Tax on profits, no Income Tax on dividends, and no tax on interest. All returns compound tax-free for as long as the money remains in the account.
Key facts for 2025/26:
- Annual allowance: £20,000 across all adult ISAs combined
- You can now pay into more than one stocks and shares ISA in the same tax year
- Flexible ISAs allow you to withdraw and replace money in the same tax year without using additional allowance (check whether your provider offers a flexible ISA)
- Transfers between ISA providers do not count as a new subscription and do not affect your annual allowance
- FSCS protection for investment ISAs: up to £85,000 per person, per firm
April 2027 Change to Watch
The government has confirmed that the annual Cash ISA allowance will be cut from £20,000 to £12,000 for savers under 65 from the 2027/28 tax year. The stocks and shares ISA allowance is not currently being reduced, but the total allowance position across all ISA types is subject to ongoing consultation. If you hold or plan to hold a Cash ISA alongside a stocks and shares ISA, it is worth keeping track of this change. Source: GOV.UK
🔍 How to Choose the Right Stocks and Shares ISA Platform
Before comparing individual platforms, it helps to know which factors matter most for your situation. The right platform for a beginner investing £100 per month in index ETFs is unlikely to be the right platform for an experienced investor actively trading individual shares.
Platform fees
What you want to invest in
If you only want low-cost index ETFs, a zero-fee platform like InvestEngine may suit you perfectly. If you want to invest in mutual funds, individual UK and US shares, investment trusts and bonds, you need a platform with a broader range, such as AJ Bell or Hargreaves Lansdown. Trading 212 is excellent for shares and ETFs but does not offer mutual funds or bonds.
Account types available
If you want an ISA and a SIPP (self-invested personal pension) on the same platform, check that both are available. Vanguard and InvestEngine offer SIPPs. Hargreaves Lansdown, AJ Bell and Freetrade also offer SIPPs. Trading 212 does not currently offer a SIPP.
Ease of use
Some platforms are app-first and designed for beginners (Trading 212, Freetrade, InvestEngine). Others offer more comprehensive desktop experiences with research tools and fund shortlists (Hargreaves Lansdown, AJ Bell). Choose based on how you actually prefer to invest.
FX fees for international shares
If you plan to buy US or other international stocks, FX fees matter significantly. Trading 212 charges 0.15% per conversion, which is the lowest among mainstream platforms. Freetrade charges 0.99% on its Basic plan. Hargreaves Lansdown charges around 1% on the first £5,000. On a £10,000 US stock purchase, that is a £150 difference between the cheapest and most expensive option.

🏦 Top Stocks and Shares ISA Providers Compared
1. Hargreaves Lansdown
Hargreaves Lansdown (HL) is the UK’s largest investment platform with over two million clients. It offers one of the widest investment ranges available, covering over 8,500 shares, 4,000 funds, 1,900 ETFs and 300 investment trusts. For investors who want comprehensive research tools, a curated fund shortlist (the Wealth Shortlist), managed portfolios, and strong customer service, HL remains the market benchmark.
Fee structure (from March 2026):
- Platform fee: 0.35% per year on funds (down from 0.45%)
- Platform fee on shares and ETFs: 0.35%, capped at £150 per year per account
- Share dealing: £6.95 per online trade (down from £11.95)
- Fund dealing: £1.95 per trade; free via regular monthly investing
- No dealing fee via regular monthly Direct Debit
Accounts available: Stocks and Shares ISA, SIPP, Lifetime ISA, Junior ISA, Fund and Share Account (GIA)
FSCS protection: £85,000
Who it suits: Investors who want the full UK investment universe in one place, value research tools and guided fund selection, or are newer to investing and want comprehensive support. Less cost-competitive for share or ETF investors compared to AJ Bell or zero-fee platforms.
Worth noting: The March 2026 fee changes were marketed as a reduction but the picture is mixed. Fund investors using regular monthly investing genuinely pay less. Share investors with ISAs now face a higher annual cap (£150 vs the previous £45). Read the full breakdown before deciding: Hargreaves Lansdown Fee Changes March 2026
2. AJ Bell
AJ Bell is one of the UK’s most established mid-market investment platforms. It offers a wide investment range comparable to HL (over 16,500 UK and international assets), with a fee structure that is meaningfully cheaper for share and ETF investors. It is listed on the London Stock Exchange and has over 670,000 clients.
Fee structure:
- Platform fee: 0.25% per year on funds
- Platform fee on shares/ETFs in ISA: 0.25%, capped at £3.50 per month (£42 per year)
- Share dealing: £5.00 per trade; free via regular investing (from May 2026)
- Fund dealing: £1.50 per trade; free via regular investing
- FX fee: 0.75% up to £10,000; tiered lower above that
Accounts available: Stocks and Shares ISA, SIPP, Lifetime ISA, Junior ISA, Junior SIPP, GIA
FSCS protection: £85,000
Who it suits: Intermediate investors who want a broad investment range but at a lower cost than HL. The £42/year cap on share fees makes it the most competitive mainstream platform for share and ETF investors with portfolios above £17,000. Which? named AJ Bell a Recommended Provider in its 2026 rankings.

3. Vanguard
Vanguard is the world’s largest mutual fund manager and pioneered the concept of low-cost index investing. Its UK platform gives direct access to around 85 Vanguard funds and ETFs at the lowest ongoing fund charges of any major provider (average OCF of approximately 0.17% to 0.20%). For passive investors focused on long-term index tracking, it remains a very competitive choice.
Fee structure (updated 2025/26):
- Platform fee: 0.15% per year, capped at £375 per year
- Minimum charge: £4 per month (£48 per year) for self-managed ISAs, SIPPs and GIAs with less than £32,000 invested
- Junior ISA: 0.15% with no minimum fee
- Managed ISA: additional 0.20% management fee; no £4 minimum applies
- Dealing: free for standard fund purchases; £7.50 for optional real-time Quote and Deal service
Accounts available: Stocks and Shares ISA, SIPP, Junior ISA, Managed ISA, Managed SIPP, GIA
FSCS protection: £85,000
Who it suits: Passive investors who want low-cost Vanguard index funds or ETFs and have at least £32,000 to invest, making the £4 monthly minimum charge proportionally small. Less suitable for investors who want access to third-party funds, individual shares, or investment trusts, as Vanguard offers only its own range.
Worth noting: Vanguard introduced the £4 monthly minimum in February 2025. For small portfolios (under £10,000), this makes Vanguard significantly more expensive on a percentage basis than InvestEngine or Trading 212. If you hold under £32,000 and want Vanguard ETFs, you can often buy the same ETFs cheaper through Trading 212 or InvestEngine.

“Vanguard’s £4 a month minimum fee can cost more than 4% a year on small ISA portfolios under £10,000. Below £32,000, it is often cheaper to buy the same funds elsewhere. #ISAPlatforms #UKInvesting”
𝕏 Share this on X4. InvestEngine
InvestEngine is a UK-based ETF platform that charges zero platform fees on its DIY portfolio option. It is authorised and regulated by the FCA, and covered by FSCS up to £85,000. For passive investors whose entire strategy is built around low-cost index ETFs, the DIY option on InvestEngine has the lowest total cost of any mainstream UK platform.
Fee structure:
- DIY portfolio: £0 platform fee, £0 dealing charge; you pay only the ETF’s own ongoing charge (OCF), typically 0.03% to 0.22% per year
- Managed portfolio: 0.25% per year (InvestEngine fee only; ETF charges apply on top)
- Minimum investment: £100
Accounts available: Stocks and Shares ISA, SIPP, Junior ISA, GIA, Business Account
FSCS protection: £85,000
Who it suits: Cost-focused investors who want to build a portfolio of index ETFs at the lowest possible price. The ETF-only model (around 700 to 800 ETFs available, no individual stocks) makes it unsuitable for investors who want to pick individual shares. Which? named InvestEngine both a Recommended Provider and a Great Value provider in its 2026 rankings.
Worth noting: InvestEngine accepts ISA transfers from other providers and can transfer ETF holdings in-specie if the receiving platform holds the same ETFs, avoiding the need to sell and repurchase.

5. Trading 212
- Platform fee: £0
- Share and ETF dealing: £0 commission
- FX fee: 0.15% per conversion (lowest mainstream rate in the UK)
- Minimum investment: £1 (fractional shares available)
6. Freetrade
Freetrade is a UK investment platform with over 1.6 million users, authorised by the FCA and FSCS-protected to £85,000. It offers commission-free access to UK and US stocks, ETFs, investment trusts and, as of January 2026, mutual funds and gilts on its free Basic plan. It has won the Best Online Trading Platform at the British Bank Awards for six consecutive years.
Fee structure (as of January 2026):
- Basic plan: Free; includes ISA, SIPP, GIA, mutual funds, gilts, and commission-free trading; FX fee 0.99%
- Standard plan: £4.99 per month; lower FX fee of 0.59%; enhanced cash interest rate
- Plus plan: £9.99 per month; FX fee 0.39%; additional features
- No platform fee on any plan
Accounts available: Stocks and Shares ISA, SIPP, Junior ISA, GIA
FSCS protection: £85,000
Who it suits: Cost-conscious investors who want commission-free access to shares and ETFs with ISA and SIPP access on one free platform. The January 2026 update making ISA and SIPP access free on the Basic plan was a significant improvement. The main trade-off is the 0.99% FX fee on the Basic plan, which makes it more expensive than Trading 212 for international stock investors.
Worth noting: Freetrade was acquired by IG Group in 2025. The pricing, FCA authorisation and FSCS coverage are unchanged following the acquisition.
7. AJ Bell Dodl
Dodl is AJ Bell’s simplified, app-only sister platform, built for investors who find the choice on full-service platforms overwhelming. Rather than offering thousands of funds and shares, Dodl deliberately limits the menu to a curated range of AJ Bell funds, themed investment baskets, and a select list of UK and US shares. It is backed by AJ Bell, a FTSE 250-listed, Which? Recommended provider for eight consecutive years.
Fee structure:
- Platform fee: 0.15% per year, minimum £1 per month, with no upper cap
- Dealing fee: £0 on shares, funds and ETFs
- FX fee: 0.75% on foreign currency investments
- Minimum investment: £100 lump sum or £25 per month
- Interest on uninvested cash: around 3.8% AER (ISA and Lifetime ISA only)
Accounts available: Stocks and Shares ISA, Lifetime ISA, Pension (SIPP), GIA
FSCS protection: £85,000
Who it suits: Genuine beginners and anyone who wants to avoid decision paralysis. Dodl’s curated fund and share list, clean app interface and flat low fee make it one of the simplest entry points into investing in the UK. It is not designed for investors who want a wide investment universe, individual stock research, or fractional shares.
Worth noting: Because Dodl’s 0.15% fee is uncapped, it can become more expensive than AJ Bell’s main platform once your portfolio grows large enough that AJ Bell’s £3.50/month share fee cap takes over. As a rough guide, portfolios above roughly £28,000 in shares or ETFs are usually cheaper on full AJ Bell than on Dodl. Dodl does not support in-specie transfers, so moving investments in or out means converting to cash first. It is also not a flexible ISA, so withdrawing and redepositing in the same tax year uses up your allowance twice.
Dodl is available at here.
✅ Which Platform Is Right for You?
There is no single best platform. The right choice depends on what you invest in, how much you hold, and how hands-on you want to be. Here is a quick decision guide:
| Your situation | Recommended platform | Why |
|---|---|---|
| You want the lowest possible cost for ETF investing | InvestEngine (DIY) | Zero platform fee; ETF costs only; FSCS-protected |
| You want to invest in shares and ETFs for free | Trading 212 | Zero fees; best FX rate; 13,000+ instruments; Cash ISA also available |
| You want low-cost index funds and a simple experience | Vanguard (if over £32,000); InvestEngine or Trading 212 (if under) | Vanguard’s 0.15% fee is competitive above £32,000; below that, the £4/month minimum erodes value |
| You want a wide investment range at fair cost | AJ Bell | 0.25% fee; £42/yr share cap; 16,500+ assets; ISA, SIPP and LISA on one platform |
| You want research tools, a curated fund list and strong customer service | Hargreaves Lansdown | Widest range; best research tools; Wealth Shortlist; two million clients |
| You want a free ISA and SIPP together with share and fund access | Freetrade (Basic) | ISA, SIPP, mutual funds and gilts all free from January 2026 |
| You are a complete beginner wanting guidance | Hargreaves Lansdown or AJ Bell | Both offer curated investment shortlists, managed portfolios, and educational content |
| You want to invest actively in US stocks | Trading 212 | 0.15% FX fee is the lowest mainstream rate; zero commission on trades |
| You are investing for the first time and want zero decision overwhelm | AJ Bell Dodl | Deliberately limited menu of funds, themes and shares; flat 0.15% fee; clean app-only experience |
💰 What Does Each Platform Actually Cost? Real Examples
Fees are easier to understand in pounds than percentages. Here is what each platform costs annually at three portfolio sizes, based on a fund-only investor who does not trade frequently. Figures are approximate and based on published platform fees only, excluding underlying fund charges.
| Platform | £10,000 portfolio | £50,000 portfolio | £100,000 portfolio |
|---|---|---|---|
| InvestEngine (DIY) | £0 | £0 | £0 |
| Trading 212 | £0 | £0 | £0 |
| Freetrade (Basic) | £0 | £0 | £0 |
| Vanguard | £48 (min fee applies) | £75 | £150 |
| AJ Bell | £25 | £125 | £250 (then 0.10% above £250k) |
| Hargreaves Lansdown | £35 | £175 | £350 (then 0.25% above £250k) |
| AJ Bell Dodl | £15 | £75 | £150 (uncapped; keeps rising at 0.15% with no ceiling) |
Note: Figures are for illustrative purposes based on published platform fees as of June 2026. They exclude fund OCFs, dealing charges, and FX fees, which will vary by how you invest. Always check current charges directly with each provider. Dodl’s fee has no annual cap, unlike AJ Bell’s main platform, so it becomes relatively more expensive as portfolios grow large.
🔒 FSCS Protection: How Safe Is Your ISA?
All seven platforms covered in this guide are authorised and regulated by the Financial Conduct Authority (FCA) and covered by the Financial Services Compensation Scheme (FSCS).
For investment platforms, FSCS protection is £85,000 per person, per firm. This applies if the platform fails and cannot return your investments. It does not protect against investment losses due to market falls.
Important clarification on the FSCS limit: The FSCS increased its compensation limit to £120,000 for deposit takers (banks and building societies) in 2024. This higher limit applies to cash savings accounts and Cash ISAs held with banks. It does not apply to investment platforms or stocks and shares ISAs. For investment firms, the limit remains £85,000.

“Common myth: FSCS protection on stocks and shares ISAs is £120,000. It is not. That higher limit only applies to banks. Investment platforms remain protected up to £85,000. #FSCS #StocksAndSharesISA”
𝕏 Share this on XIf you hold more than £85,000 with a single investment platform, consider whether you want to spread holdings across more than one provider for additional protection.
🔎 Common Questions About Stocks and Shares ISAs
Q: Can I hold more than one stocks and shares ISA?
Yes. From the 2024/25 tax year onwards, you can pay into more than one stocks and shares ISA in the same tax year. You simply need to ensure your total ISA contributions across all types of ISA do not exceed £20,000 in a single tax year.
Q: Can I transfer my ISA to a different platform?
Yes, ISA transfers are straightforward and do not affect your annual ISA allowance. You can transfer in cash (the platform sells your investments before transferring) or in-specie (your investments transfer across directly, subject to both platforms supporting the same holdings). Most platforms offer free ISA transfers in. Some charge exit fees on the way out; always check before moving.
Q: What is the difference between a DIY ISA and a managed ISA?
A DIY (do-it-yourself) ISA means you choose your own investments. A managed ISA means the platform selects and manages a portfolio on your behalf, typically based on a risk level you choose. Managed options cost more (InvestEngine charges 0.25%; Vanguard charges 0.20% for its managed service on top of its standard fee) but suit investors who prefer a hands-off approach.
Q: Is it safe to use newer platforms like Trading 212 or Freetrade?
Both are FCA-authorised and FSCS-protected to £85,000. FCA authorisation means client money and assets must be held separately from the firm's own money. If the platform fails, your investments are ring-fenced and should be returned to you or transferred to another provider. FSCS covers you if the firm fails and cannot return your assets. That said, newer or smaller platforms do carry a different risk profile to established names like HL or AJ Bell, which have decades of operating history and larger capital bases.
Q: What is the annual ISA allowance for 2025/26?
The annual ISA allowance is £20,000 across all adult ISAs combined for the 2025/26 tax year. For Junior ISAs, the allowance is £9,000. The Lifetime ISA allows contributions of up to £4,000 per year (counting towards the £20,000 total), with a 25% government bonus up to £1,000 per year.
Q: Which stocks and shares ISA platform is best?
It matters more than most people realise, primarily because of fees. Platform charges are deducted regardless of whether your investments go up or down. Over a 20 to 30 year investing horizon, the compounding effect of even a 0.20% annual fee difference is significant. That said, the most important decision is to start investing. Switching platforms later is straightforward via ISA transfer.
There is no single platform that is best for everyone. For the lowest possible cost on ETF investing, InvestEngine and Trading 212 both charge no platform fee. For a wider range of funds, shares and bonds alongside strong research tools, AJ Bell and Hargreaves Lansdown tend to suit investors better. The right answer depends mainly on what you want to invest in and how much you hold.
Q: How do I choose a stocks and shares ISA?
Start by working out what you actually want to invest in (funds, individual shares, ETFs, or a mix), then compare platform fees against that. Check whether the platform offers the account types you need (ISA, SIPP, Lifetime ISA), and look at dealing charges and FX fees if you plan to trade often or buy international stocks. The comparison table earlier in this guide is a good starting point for narrowing this down.
Q: What is the best platform for a stocks and shares ISA?
For most UK investors focused on long-term, low-cost investing, InvestEngine, Trading 212 and AJ Bell are consistently competitive on price. For investors who want a fuller service with research tools and guided fund selection, Hargreaves Lansdown remains a strong, well-established option, even though it costs more. The best platform genuinely depends on your portfolio size, what you invest in, and how hands-on you want to be.
