Frequently Asked Questions
Fidelity charges a platform fee of 0.35% per year on the value of your ISA holdings, with a maximum cap of £45 per year for shares, ETFs, and investment trusts. For ISAs holding over £25,000 in shares and ETFs, the platform fee is waived entirely. Fund dealing is free; share dealing costs £7.50 per trade online.
Fidelity is cheaper than HL for most investors. The platform fee is 0.35% vs HL's 0.45%, fund dealing is free at both, but share dealing is £7.50 at Fidelity vs £11.95 at HL. For larger portfolios above £25,000 in shares/ETFs, Fidelity waives the platform fee entirely — making it significantly cheaper.
Yes. Fidelity International is authorised and regulated by the FCA (reference number 222525). Your investments are protected by the Financial Services Compensation Scheme (FSCS) up to £85,000 per person if Fidelity were to fail as a firm. This protection covers firm failure, not investment losses.
Yes. Fidelity offers a wide range of ETFs from providers including iShares, Vanguard, SPDR, Xtrackers, and Invesco. You can buy ETFs from UK, US, and European markets within your ISA. ETF dealing costs £7.50 per trade, or free through the regular savings plan.
Pathfinder portfolios are Fidelity's ready-made investment options designed for investors who prefer not to pick individual funds. There are seven risk-graded portfolios ranging from cautious to adventurous. Each is professionally managed and diversified across global asset classes. The minimum investment is £1,000 lump sum or £25/month.
Yes. Fidelity accepts ISA transfers from all UK providers. Cash transfers typically complete within 15-30 working days. In-specie transfers (moving existing holdings without selling) are available for funds and shares that Fidelity can hold. Transferring preserves your ISA tax-free status and does not count towards your annual allowance.
No. Fidelity does not currently offer a Lifetime ISA (LISA). If you want a LISA alongside your Stocks and Shares ISA, you would need to open one with another provider such as AJ Bell or Hargreaves Lansdown. Remember that LISA contributions count towards your overall £20,000 ISA allowance.
The annual ISA allowance is £20,000 for the 2025/26 tax year. This is a HMRC limit, not a Fidelity limit — it applies across all ISA providers and types. You can invest up to £20,000 in a Fidelity Stocks and Shares ISA, or split the allowance between a Cash ISA, Stocks and Shares ISA, Lifetime ISA (max £4,000), and Innovative Finance ISA.

What Is the Fidelity ISA?
Key Findings
Key Findings & Analysis
Competitive platform fee of 0.35% with no dealing charges on funds — excellent for regular investors
Extensive global fund range including 3,000+ funds, ETFs, investment trusts, and individual shares
No platform fee on ETFs and shares over £25,000 — exceptional for larger portfolios
Pathfinder ready-made portfolios for hands-off investors starting from £1,000
Bottom line: Cost-conscious UK investors building a diversified ISA portfolio through global ETFs and index funds, who want broader choice than Vanguard without paying HL's premium fees
The Fidelity Stocks and Shares ISA is a tax-efficient investment wrapper offered by Fidelity International, one of the world's largest asset management firms with over $4.5 trillion in assets under management globally. Operating independently from its US counterpart, Fidelity International brings institutional-grade investment infrastructure to UK retail investors through a platform that balances breadth of choice with competitive pricing. The firm has been serving UK investors for over 30 years, building a track record that few challenger platforms can match.
Within a Fidelity ISA, your investments grow entirely free of capital gains tax and income tax. You pay no tax on dividends received, no tax on profits when you sell investments, and no additional tax when you withdraw funds. For higher-rate and additional-rate taxpayers, this tax shelter becomes particularly valuable as it eliminates up to 24% capital gains tax and up to 39.35% dividend tax that would otherwise erode returns in a general investment account.
Fidelity positions itself as the smart middle ground in the UK ISA market — more choice and flexibility than Vanguard's own-brand-only range, at a significantly lower cost than Hargreaves Lansdown's 0.45% platform fee. With 3,000+ funds, 500+ ETFs, 400+ investment trusts, and access to individual shares on UK, US, and European exchanges, it offers genuine breadth without the premium price tag. The platform serves everyone from first-time ISA investors using Pathfinder ready-made portfolios through to experienced self-directed investors running multi-asset portfolios.

ISA Allowance & Tax Benefits
The £20,000 Tax-Free Allowance
Every UK resident aged 18 or over can invest up to £20,000 per tax year (6 April to 5 April) into ISAs. This allowance is set by HMRC and applies across all ISA providers and types combined. You can allocate the full £20,000 to a Fidelity Stocks and Shares ISA, or split it between different ISA types according to your financial goals.

The Power of Tax-Free Compounding
The true value of an ISA reveals itself over time through compounding within a tax wrapper. When your investments grow and generate dividends, those returns are reinvested without any tax deduction — unlike a general investment account where capital gains tax (up to 24%) and dividend tax (up to 39.35%) erode your returns year after year. For a higher-rate taxpayer investing £20,000 annually at 7% average growth over 20 years, the difference between an ISA and a taxed general investment account can exceed £130,000 in cumulative tax savings.
Use it or lose it. Your £20,000 ISA allowance cannot be carried forward to the next tax year. Any unused allowance on 5 April is lost permanently. Even investing a small amount before the deadline opens an ISA for that tax year, which you can then top up at any point before the following 5 April.
Fees & Cost Analysis
Fidelity Fee Structure
Fidelity's pricing sits firmly between the budget platforms and the premium incumbents. The 0.35% platform fee on funds undercuts Hargreaves Lansdown's 0.45% by a meaningful margin, while the fee waiver on shares and ETFs above £25,000 creates a significant advantage for growing portfolios. Fund dealing carries no charge at all, and the regular savings plan lets you invest from £25 per month per fund with free dealing across both funds and ETFs.

True Cost Comparison
On a £50,000 ISA portfolio held for 10 years (50% funds, 50% ETFs), the platform fee differences compound into substantial savings. Fidelity's fee structure saves nearly £800 compared to Hargreaves Lansdown over a decade, and the gap widens further once the ETF-heavy portion exceeds £25,000 and the platform fee drops to zero. For cost-conscious investors building wealth over 20-30 years, these savings compound into thousands of pounds of additional returns.

The £25,000 ETF threshold: Fidelity waives its platform fee entirely on shares and ETFs once your holdings exceed £25,000. For an ETF-focused investor with a £50,000+ portfolio, Fidelity becomes one of the cheapest mainstream platforms in the UK — even cheaper than Vanguard for those wanting broader choice beyond own-brand index funds.
Fund Range & ETF Selection
Investment Universe
Fidelity provides access to one of the broadest investment ranges available within a UK ISA wrapper. Unlike Vanguard, which restricts you to its own approximately 80 funds, Fidelity opens the door to over 3,000 funds from dozens of asset managers including Fundsmith, Baillie Gifford, Liontrust, and Jupiter alongside Fidelity's own highly-regarded fund range. The ETF selection spans 500+ products from iShares, Vanguard, SPDR, Xtrackers, and Invesco, covering everything from global equity trackers to thematic and factor-based strategies.

Fidelity Select 50
The Select 50 is Fidelity's curated fund shortlist — their equivalent of HL's Wealth Shortlist. Fidelity's research team handpicks these funds based on long-term performance track record, quality of fund management, competitive fee structures, and clear investment processes. The Select 50 covers all major asset classes and geographies, making it an excellent starting point for investors who want guidance without paying for full portfolio management. Each fund comes with detailed research notes explaining why it was selected and where it fits within a diversified portfolio.
Pathfinder Ready-Made Portfolios
For investors who prefer a hands-off approach, Fidelity offers seven Pathfinder portfolios ranging from cautious to adventurous. Each portfolio is professionally managed, automatically rebalanced, and diversified across global markets. The minimum investment is £1,000 as a lump sum or £25 per month via regular savings, making Pathfinder accessible to beginners and experienced investors alike.

Pathfinder portfolios charge relatively low underlying fund fees (0.20-0.23%) on top of the 0.35% platform fee, bringing total annual costs to roughly 0.55-0.58%. This compares favourably with Nutmeg's managed portfolios (0.75% management fee plus fund costs) and is broadly in line with Vanguard LifeStrategy funds (0.22% fund charge plus 0.15% platform fee). The key advantage over Vanguard LifeStrategy is that Pathfinder uses a wider range of underlying fund managers rather than relying solely on Vanguard's own index funds.
Pathfinder vs DIY: If you are new to investing or prefer simplicity, a Pathfinder portfolio gives you instant diversification without needing to select individual funds. As your confidence and knowledge grow, you can switch to a self-selected portfolio at any time with no penalty or exit fee.
Platform Experience & App
Desktop Platform
Fidelity's web platform provides a clean, functional experience focused on long-term investing rather than active trading. The portfolio overview displays your asset allocation breakdown, total returns, and individual holding performance in a straightforward layout. The ISA allowance tracker shows your remaining tax-year capacity at a glance, which is genuinely useful in the weeks leading up to the 5 April deadline. Research tools include Select 50 fund recommendations with analyst notes, performance charting and comparison tools, and a regular savings plan management interface that makes setting up monthly contributions straightforward.
Mobile App
The Fidelity app (rated 4.4/5 on App Store) delivers the core functionality you need: buying and selling funds, ETFs, and shares; checking portfolio valuation and performance; setting up regular savings plans; viewing research insights and market commentary; and biometric login via Face ID or fingerprint. The app is reliable and functional for investors who primarily use their ISA for regular monthly contributions and occasional portfolio reviews.
Where Fidelity falls short is in app polish compared to Hargreaves Lansdown (rated 4.7/5). HL's app offers richer research content, analyst video commentary, and a more refined user interface. If premium research tools and app experience rank among your top priorities, HL justifies its higher fees for that audience. For cost-focused investors, Fidelity's app does everything you need without the premium price tag.
Regular savings plans are the hidden gem. Setting up a monthly contribution plan through Fidelity costs nothing in dealing fees for both funds and ETFs. This pound-cost averaging approach removes the stress of market timing and is particularly effective for ISA investors building wealth steadily over decades.
FCA Regulation & FSCS Protection
Fidelity International is authorised and regulated by the Financial Conduct Authority (FCA), reference number 222525. This regulatory status provides comprehensive protection for UK investors across multiple layers. Your investments are held in nominee accounts entirely separate from Fidelity's own company assets, meaning that if Fidelity were to fail as a firm, your investments would be identifiable and returnable through the normal client asset process.
The Financial Services Compensation Scheme (FSCS) provides an additional safety net, protecting you up to £85,000 per person in the event that Fidelity fails and your assets cannot be returned through the standard process. It is important to understand that FSCS covers firm failure, not investment losses — if your portfolio drops in value due to market movements, that is investment risk rather than a matter of regulatory protection.
Full FCA Protection Details4
Show detailsHide details
Client asset segregation: Your investments are held in nominee accounts separate from Fidelity's own company assets, ensuring they are ring-fenced in the event of firm insolvency
FSCS protection: The Financial Services Compensation Scheme protects you up to £85,000 per person if Fidelity fails and your assets cannot be returned
FCA conduct rules: Fidelity must treat customers fairly, provide clear information about fees and risks, and handle complaints within regulated timeframes
Financial Ombudsman Service: You can escalate unresolved complaints to the FOS free of charge, with binding decisions up to £415,000
Capital at risk. The value of investments within a Stocks and Shares ISA can go down as well as up. You may get back less than you invest. Tax treatment depends on your individual circumstances and may be subject to change in future. FSCS protection covers firm failure only, not investment performance losses.

When to Choose Fidelity
Fidelity is the strongest choice for investors who want broad fund and ETF choice at a lower cost than Hargreaves Lansdown. If you are building an ETF-focused portfolio above £25,000, the free platform fee makes Fidelity one of the most cost-effective options in the market. The Select 50 research guidance provides curated fund recommendations without HL's premium pricing, and Pathfinder ready-made portfolios offer a genuinely good hands-off option for those who prefer professional portfolio management. Fidelity also suits investors who want global fund diversity beyond Vanguard's own-brand range but do not want to pay HL-level fees for the privilege.
When to Choose Alternatives
Hargreaves Lansdown: You want the widest possible choice, best research tools, and premium app experience — and are willing to pay 0.45% for it
Vanguard: You only want Vanguard index funds and want the absolute lowest fee (0.15%)
AJ Bell: You want individual shares at a cheaper dealing price (£5 per trade)
Trading 212: You want zero platform fees and primarily trade individual shares
After thorough analysis, the Fidelity Stocks and Shares ISA earns 4.6 out of 5 stars as the best mid-cost ISA platform for global ETF investors and cost-conscious long-term savers in 2026.
Bottom line: Fidelity occupies the sweet spot in the UK ISA market. You get HL-level fund choice (3,000+ funds) at a significantly lower cost (0.35% vs 0.45%). The free platform fee on shares and ETFs above £25,000 makes Fidelity the most cost-effective mainstream platform for growing portfolios. The Select 50 provides solid research guidance, and Pathfinder portfolios offer a professionally managed hands-off option at competitive total costs.
Where Fidelity falls short is in app polish and the premium research experience. HL's Wealth Shortlist content, analyst videos, and desktop platform remain best-in-class for investors who value deep research tools. If you prioritise research quality and are willing to pay for it, HL justifies its premium. But for investors focused on cost efficiency and long-term wealth building, Fidelity delivers more value per pound invested than any other full-service platform.
