Best UK Investment Platforms: 2026 Comparison
Choosing the right platform matters more than most people realise. The difference in ongoing fees between platforms, even fractions of a percent, compounds into thousands of pounds over decades. The platform you pick also determines which investments you can access, how easy the experience is, and how much it costs to invest regularly.
This page compares the main platforms for UK passive investors, people who want to invest in low-cost index funds inside a Stocks and Shares ISA, Lifetime ISA, or SIPP. It’s written for people who want clear, honest information rather than a list of referral bonuses.
| Affiliate disclosure Some platforms on this page have affiliate programmes, if you open an account using our links, we may receive a small referral fee at no cost to you. We’ve noted which platforms these are in each review. This disclosure is required by law and by our own editorial standards. Affiliate status has not influenced how any platform is assessed or where it appears in this comparison. |
How We’ve Assessed These Platforms
Every platform is evaluated on the same five criteria, regardless of whether we have an affiliate relationship with them:
- Platform fees, the annual charge for holding your investments
- Fund range, access to the low-cost global index funds that passive investors need
- Regular investing, whether monthly contributions can be made free of charge
- Account types available, ISA, LISA, SIPP, general account
- Usability, how easy the platform is to set up and use day-to-day
We’ve also noted minimum investment requirements and any notable limitations for each platform. The comparison table gives you the quick view; the individual reviews below give you the context you need to make a decision.

The Reviews
The platforms below are ordered by how well they suit the typical reader of this site, someone investing monthly in index funds, primarily through a Stocks and Shares ISA, on a budget of £100–£1,000 per month.
InvestEngine
The best platform for low-cost passive investing, and it’s hard to argue otherwise
| Accounts | Stocks & Shares ISA, Lifetime ISA, SIPP, General Account |
| Platform fee | 0%, no platform fee at all on personal accounts |
| Fund range | ETFs only, wide selection including Vanguard, iShares, Fidelity, and more |
| Minimum investment | £1 minimum |
What Works Well:
- Zero platform fee, the cheapest option by a significant margin for most investors
- Strong ETF selection covering all the major global index funds UK investors need
- Free regular investing, set up a monthly direct debit into any ETF at no cost
- Both ISA and LISA available, unusual to find both in one low-cost platform
- SIPP available, rare to get all three main tax wrappers in one place at zero platform cost
- Clean, straightforward interface, not overloaded with features most passive investors don’t need
- Managed portfolio option available if you want the platform to handle allocation
Worth Knowing:
- ETFs only, no access to Vanguard unit trusts or other non-ETF funds
- No access to individual shares, pure passive investors won’t miss this, but worth noting
- Relatively newer platform compared to established names, though FCA-regulated and FSCS-protected
- Customer service by email and chat only, no telephone support
Best for: Most passive investors. If you’re investing in index fund ETFs inside an ISA, LISA, or SIPP, InvestEngine’s zero platform fee is very hard to beat. The main reason to look elsewhere is if you specifically want Vanguard unit trusts rather than ETFs, or if you want to trade individual shares alongside your index funds.

Trading 212
Zero fees, excellent app, and access to both ETFs and individual shares
| Accounts | Stocks & Shares ISA, Lifetime ISA, General Account (no SIPP) |
| Platform fee | 0%, no platform fee |
| Fund range | ETFs including all major passive funds, plus thousands of individual stocks |
| Minimum investment | £1 minimum (fractional shares available) |
What Works Well:
- Zero platform fee, matches InvestEngine on cost for ISA investing
- Excellent mobile app, arguably the best user experience of any platform reviewed here
- Fractional shares, invest in any company from £1, useful for small regular amounts
- Lifetime ISA available, one of few zero-fee platforms offering a LISA
- Very wide fund and stock range, more choice than most passive investors need, but it’s there
- AutoInvest feature, set rules to automatically invest regular amounts
- Free instant bank transfers in and out
Worth Knowing:
- No SIPP, if pension investing is important alongside your ISA, you’ll need a second platform
- Very wide range can feel overwhelming for beginners who just want one global index fund
- Funded partly through payment for order flow on some trades, less relevant for buy-and-hold investors
- Customer support can be slow during busy periods
Best for: Beginners who want a great mobile experience and zero fees. Also suits investors who want both passive index fund exposure and the option to hold individual company shares in one place. Not suitable as a standalone platform if you need a SIPP.

Vanguard UK
Low-cost, no-fuss, and the home of the world’s most popular index funds
| Accounts | Stocks & Shares ISA, SIPP, General Account (no LISA) |
| Platform fee | 0.15% per year, capped at £375/year for accounts over £250,000 |
| Fund range | Vanguard funds only, around 80 funds including their full index and LifeStrategy range |
| Minimum investment | £1 minimum (£100 minimum lump sum) |
What Works Well:
- Very low platform fee, 0.15% is competitive, especially capped at £375 for large portfolios
- Direct access to Vanguard’s unit trust funds, not available on all other platforms
- LifeStrategy funds, simple one-fund solutions for investors who want automatic asset allocation
- Highly reputable, established provider with a long track record
- SIPP available, useful for retirement investing
- Clean, simple interface focused on long-term investing
Worth Knowing:
- Vanguard funds only, no access to iShares, Fidelity, or any non-Vanguard ETF
- No LISA, if you want a Lifetime ISA, you’ll need a different platform
- Not the cheapest option for smaller portfolios where 0.15% vs 0% makes a meaningful difference
- No individual shares, pure funds platform
- No affiliate programme, we have no financial relationship with Vanguard
Best for: Investors who specifically want Vanguard unit trusts (especially LifeStrategy funds), investors with larger portfolios who benefit from the capped fee, or anyone who values the simplicity of sticking with one well-known provider. Less suitable for those who want a LISA or access to non-Vanguard funds.
No affiliate relationship, Vanguard
We don’t have an affiliate arrangement with Vanguard. They’re included in this comparison because they’re genuinely one of the best options for many UK investors. Our recommendation to use Vanguard where appropriate is entirely editorial.
Freetrade
Now genuinely fee-free, with ISA and SIPP both available on the free plan
| Accounts | Stocks & Shares ISA, SIPP, General Account (no LISA) |
| Platform fee | 0%, no platform fee on Basic plan |
| Fund range | ETFs, stocks, mutual funds, and gilts |
| Minimum investment | £2 minimum |
What Works Well:
- ISA and SIPP both available on the free Basic plan, no monthly subscription required
- Zero platform fee, genuinely free for most passive investors following the January 2026 changes
- Good ETF selection covering the main passive index funds UK investors need
- Mutual funds and gilts now included on the free plan, broader than most zero-fee platforms
- Clean, app-first experience that beginners find easy to navigate
- Wide stock range if you want to combine passive and active investing
- Fractional shares available, invest in any stock from £2
- SIPP available at no extra cost, useful for consolidating old pensions
Worth Knowing:
- No LISA, if a Lifetime ISA is important you will need a different platform
- FX fee of 0.99% on overseas trades on the Basic plan, higher than some rivals
- Pricing model has changed several times in recent years, worth checking current terms before committing
- Interest on uninvested cash is lower than some alternatives
- Customer support is app and email only, no telephone support
Best for: Investors who want a free ISA and SIPP in one place, alongside access to both index fund ETFs and individual shares. Following the January 2026 pricing changes, Freetrade is now a genuine zero-fee alternative to InvestEngine and Trading 212 for straightforward ISA investing. Less suitable if you need a Lifetime ISA, or if low FX fees matter to you for overseas stock trading.

Hargreaves Lansdown
The UK’s largest platform, broad, reliable, and more expensive than the alternatives
| Accounts | Stocks & Shares ISA, Lifetime ISA, SIPP, Junior ISA, General Account, the full range |
| Platform fee | 0.35% on a £50,000 portfolio is £175/year |
| Fund range | Extremely wide, funds, ETFs, investment trusts, individual shares, bonds |
| Minimum investment | £25 minimum regular investment, £1 lump sum |
What Works Well:
- Widest account range, every account type including Junior ISA in one place
- Telephone support, important for less confident investors or complex queries
- Extremely wide fund and share range, access to almost anything
- Long-established, highly regulated, trusted brand
- Good research tools and educational resources built in
- Excellent for consolidating everything in one place as portfolio grows
Worth Knowing:
- 0.35% on a £50,000 portfolio is £175/year
- For a passive investor in two or three index funds, most of the platform’s breadth is unused
- £6.95 per ETF trade makes regular small ETF purchases genuinely expensive (though funds are free to trade)
- The fee cap on shares helps larger investors but doesn’t help smaller passive investors
- No affiliate programme, no financial relationship with this site
Best for: Investors who value breadth, telephone support, and keeping everything with one well-established provider. Also suits larger investors where the 0.35% fee cap on ETFs makes the effective rate competitive. Hard to recommend for straightforward passive ISA investing where zero-fee platforms offer the same funds at a fraction of the cost.
No affiliate relationship, Hargreaves Lansdown
We don’t have an affiliate arrangement with HL. They’re one of the UK’s most well-known investment platforms and many readers will already hold accounts with them, it would be wrong to leave them out of a UK platform comparison.
Which Platform Should You Choose?
There’s no universally correct answer: the right platform depends on your accounts, portfolio size, and what you want to invest in. But for the typical reader of this site, a UK investor wanting a Stocks and Shares ISA to invest in global index funds, the choice is fairly clear:
| Your Priority | Recommended Platform |
| Lowest possible cost, ISA only | InvestEngine or Trading 212, both zero platform fees, both good ETF ranges |
| ISA + LISA in one place | InvestEngine or Trading 212, both offer ISA and LISA at zero platform cost |
| ISA + SIPP in one place, zero fees | InvestEngine, the main zero-fee platform with all three wrappers |
| Specifically want Vanguard unit trusts | Vanguard UK, direct access to LifeStrategy and the full fund range |
| Best mobile app experience | Trading 212, the most polished interface of any platform reviewed |
| ETFs + individual shares combined | Trading 212 or Freetrade, both offer wide stock ranges alongside ETFs |
| Large portfolio, everything in one place | Hargreaves Lansdown, fee cap helps at scale, widest account and fund range |
| Telephone support important | Hargreaves Lansdown, the only platform here with full telephone service |
What About Robo-Advisers?
Robo-advisers, platforms like Nutmeg, Moneybox, Wealthify, and Moneyfarm, manage your investments for you based on a questionnaire about your goals and risk tolerance. They’re often marketed at people who find investing intimidating.
They’re not covered in detail on this page because their fees, typically 0.25–0.75% platform fee on top of fund costs, make them significantly more expensive than choosing your own global index fund on a zero-fee platform. The investment outcome is generally similar: a diversified portfolio of funds. You’re paying for the management element.
For most people who’ve read the Fundamentals section of this site, a single global index fund on InvestEngine or Trading 212 achieves essentially the same result at a fraction of the cost. If the idea of choosing a fund still feels overwhelming, a Vanguard LifeStrategy fund on the Vanguard platform is a legitimate middle ground, automatic asset allocation, very low cost, no ongoing decisions required.
How to Switch Platforms
If you already have an ISA with one platform and want to move to a different one, you can transfer your ISA without losing the tax-free status, provided you use the formal ISA transfer process rather than withdrawing and reinvesting.
- Contact your new platform and initiate the transfer from there, don’t withdraw from your existing platform
- In-specie transfers move your existing investments without selling them, not all platforms support this
- Cash transfers sell your investments, move the cash, and you reinvest on the new platform, simpler but means time out of the market
- Transfers typically take 2-4 weeks for cash, longer for in-specie
- Check for exit fees on your current platform before transferring, most modern platforms don’t charge them, but some older ones do
A Note on Platform Safety
All platforms reviewed on this page are regulated by the Financial Conduct Authority (FCA) and participate in the Financial Services Compensation Scheme (FSCS), which protects up to £85,000 of investments per regulated firm if a platform fails.
It’s worth understanding that FSCS protection applies to the failure of the platform, not to investment losses. If your investments fall in value because markets fall, the FSCS doesn’t apply, that’s normal investment risk. The protection is specifically for the scenario where the platform itself goes under.
| Keeping above the FSCS limit If your investments with a single platform exceed £85,000, some investors spread across two platforms for FSCS coverage. In practice, large established platforms are very unlikely to fail, the regulatory requirements are stringent, but for very large portfolios it’s a reasonable consideration. |
| Not financial advice This page is a factual comparison of UK investment platforms based on publicly available information. It is not a personalised recommendation. The right platform for you depends on your individual circumstances, account needs, and investment goals. Fee information is accurate at time of writing but changes, always verify current fees on each platform’s website before opening an account. Affiliate links are clearly labelled. We receive a referral fee for some platforms, this does not influence our editorial assessment. |
What Next?
With your platform chosen and your account open, the next step for many UK investors is understanding how to invest in the most tax-efficient order, combining your ISA, pension, and LISA in the right sequence. Our tax-efficient investing guide covers exactly that.
