Fidelity International
vs Vanguard UK (2026)
Two of the most established names in UK investing — with fundamentally different philosophies. Vanguard is a closed, low-cost ecosystem built around passive index funds. Fidelity is an open platform with 10,000+ investment options, a fee cap that rewards larger ISA and SIPP holders, and tools for engaged investors. This guide covers fees, fund access, ISA, SIPP, platform experience, and which one fits your situation.

TL;DR
- You want access to 10,000+ funds, ETFs, investment trusts, and individual shares
- Your ISA or SIPP is above ~£25k — the £90/year ETF cap saves real money at scale
- You invest in a general (non-ISA) account — Fidelity charges zero platform fee on ETFs/shares in a GIA
- You want active funds, investment trusts, or third-party managers alongside index funds
- You want research tools and fund screening to make more informed decisions
- You want a simple, low-cost platform with no distractions — one or two index funds and done
- Your plan is entirely within Vanguard’s fund range (LifeStrategy, All-World, etc.)
- Your portfolio sits between £32k–£60k and you want a lower custody percentage
- You want £0 FX charges — all Vanguard products are GBP-priced, no conversion occurs
- You prefer fewer options — Vanguard’s limited range reduces the risk of behavioural mistakes

What can you actually buy?
This is the most significant structural difference between the two platforms. It shapes not just what you can invest in — but how you think about investing day to day.
Fidelity operates as a fund supermarket: access to funds from hundreds of managers (including Vanguard, BlackRock, HSBC, Baillie Gifford, and more), UK and US individual shares, investment trusts, ETFs, and bonds — all in one account. If your strategy evolves, you never need to move platform.
- UK and US individual stocks
- ETFs from iShares, Vanguard, Xtrackers, HSBC, and others
- Thousands of third-party active and passive funds
- Investment trusts (e.g. Scottish Mortgage, etc.)
- Bonds and gilts
- Managed and ready-made portfolios
Vanguard’s platform only carries Vanguard’s own funds and ETFs — around 85 products total. No individual shares, no third-party managers, no investment trusts. For investors who have committed to a Vanguard-only index strategy, this is exactly enough. For anyone else, it’s a ceiling.
- Vanguard index funds (FTSE All-World, LifeStrategy series, etc.)
- Vanguard ETFs listed on the London Stock Exchange
- Vanguard target-date and active ranges
- No stocks, no third-party products
Fees — what you actually pay
Platform fees look simple on paper. The detail is in the minimums, caps, and per-trade costs — which change the ranking at different portfolio sizes and account types.
Vanguard charges 0.15% p.a. on all assets — lower than Fidelity’s rate in percentage terms. But Vanguard applies a £4/month minimum fee (£48/year) for any account under £32,000. Below that threshold the effective rate is far higher than 0.15% implies. A £5,000 portfolio costs £48/year — that’s an effective 0.96% rate.
Fidelity charges 0.35% p.a. with no minimum. For ETFs and shares held in an ISA or SIPP, the fee is capped at £90/year — meaning once your portfolio passes roughly £25,700, your custody cost stays fixed regardless of growth. In a standard general investment account (GIA), Fidelity charges no platform fee at all on ETFs and shares.
Annual custody cost by portfolio size — ISA, ETF/share holdings
| Portfolio size | Vanguard (annual custody) | Fidelity ETF ISA (annual custody) | Winner on custody |
|---|---|---|---|
| £5,000 | £48.00 (min applies; eff. 0.96%) | £17.50 (0.35%) | Fidelity |
| £10,000 | £48.00 (min applies; eff. 0.48%) | £35.00 (0.35%) | Fidelity |
| £20,000 | £48.00 (min applies; eff. 0.24%) | £70.00 (0.35%) | Vanguard |
| £32,000 | £48.00 (min = 0.15%) | £90.00 (cap kicks in) | Vanguard |
| £50,000 | £75.00 (0.15%) | £90.00 (capped) | Vanguard |
| £100,000 | £150.00 (0.15%) | £90.00 (capped) | Fidelity |
| £250,000 | £375.00 (0.15%, cap level) | £90.00 (capped) | Fidelity |
Annual custody fees only — excludes dealing fees and FX charges. Fidelity GIA (non-ISA) charges £0 platform fee on ETFs and shares regardless of portfolio size. Fidelity’s £90 cap applies to ISA and SIPP only, and only to ETF/share holders — fund (OEIC) investors pay 0.35% uncapped.
Funds (unit trusts / OEICs): Free on both platforms. No dealing fee for mutual fund purchases at either Fidelity or Vanguard.
ETFs — Fidelity: £7.50 per single trade. Regular savings (recurring monthly purchases) cost £1.50 per trade — a meaningful saving for systematic monthly investors who don’t need to hand-pick timing.
ETFs — Vanguard: Free via batch dealing, executed twice daily. £7.50 if you need instant execution via Quote and Deal. Most long-term buy-and-hold investors have no reason to use the instant route — the batch method is effectively free ETF trading.
Vanguard: 0% FX charge. All products on the Vanguard UK platform are priced in GBP — no currency conversion takes place. This is a genuine advantage for investors who want clean, simple GBP investing without any FX drag.
Fidelity: Tiered FX charge on international assets — 0.75% on the first £10,000 converted, 0.50% on £10,001–£20,000, and 0.25% above £20,000. This applies when trading US shares or non-GBP-priced instruments. For GBP-denominated UCITS ETFs on UK exchanges (which most UK passive investors hold), no FX conversion is triggered.
Interface, tools, and day-to-day usability
For a long-term buy-and-hold investor, platform friction matters less than for active traders. But onboarding complexity and navigation still affect whether people stick to their plan.
Fidelity’s platform carries more surface area — a reflection of the breadth of products available. The interface is functional and well-established, with strong fund filtering, comparison tools, portfolio analysis, and market research. New investors may find it more complex than they need at first — but most features can simply be ignored.
- Fund comparison and screening tools
- Portfolio quick check and asset allocation breakdown
- Market news, research, and fund factsheets
- Regular savings setup is straightforward
- Mobile app functional; more complex than Vanguard
Vanguard’s platform is intentionally stripped back. You browse a small range of products, pick one or two, set up a direct debit, and walk away. There’s limited research, no market data feed, and no fund discovery tools — because Vanguard has decided you don’t need them. For long-term passive investors, this is a feature, not a limitation.
- Clean, fast onboarding
- Easy direct debit and monthly investing setup
- No analysis tools, no market news
- Mobile app basic but sufficient for passive investors
- Fewer decisions = fewer opportunities for behavioural mistakes
ISA, SIPP, and account types
Both platforms offer the standard UK tax wrappers. The material differences appear in SIPP fee structure, GIA treatment, and Junior SIPP availability.
- Stocks and Shares ISA — 0.35% p.a., capped at £90/year for ETF/share holders
- SIPP — same fee structure as ISA; full SIPP flexibility including drawdown
- Junior ISA — for children under 18; same cap applies
- Junior SIPP — available; a differentiator vs Vanguard
- General Investment Account (GIA) — 0% platform fee on ETFs/shares; 0.35% on funds only
- Stocks and Shares ISA — 0.15% p.a.; £4/month min under £32k; capped at £375/year
- Personal Pension (SIPP) — same 0.15% structure; Vanguard products only
- Junior ISA — available; same 0.15% fee structure applies
- General Account (GIA) — same 0.15% (with £4/month min); no fee-free GIA tier
- No Junior SIPP available
Two different approaches to the same goal
The product difference is obvious. The philosophical difference is what actually matters for long-term behaviour.
Vanguard’s platform is built around the idea that most investors are better served by a one- or two-fund passive portfolio than by a complex allocation. The limited product range isn’t a design limitation — it’s the product. Pick a LifeStrategy or All-World fund, set up a direct debit, and stop looking at it. Fewer decisions means fewer mistakes. For investors who have accepted this philosophy, Vanguard is the natural home.
Fidelity is built for investors who want more control — whether that means mixing passive and active strategies, holding individual UK shares alongside ETFs, or using research tools to make informed decisions. The breadth is genuinely valuable if you use it purposefully. The risk is that 10,000 products create 10,000 opportunities to make decisions you didn’t need to make. Discipline matters more on an open platform.
Which broker fits your situation?
Six scenarios where one platform has a clear edge. Use these as a shortcut if you’re already close to a decision.
→ Vanguard (if investing monthly £100+). One LifeStrategy or FTSE All-World fund, a direct debit, no decisions to make after setup. Vanguard’s limited range is precisely what most beginners need — a platform that doesn’t tempt them to tinker. Note: Fidelity’s £25/month regular savings minimum is lower than Vanguard’s £100/month floor, which matters for very small starting budgets.
→ Fidelity. Above roughly £60,000 in an ETF ISA, Fidelity’s £90 cap means your annual custody cost is fixed — while Vanguard’s 0.15% keeps rising with the portfolio. At £100k you save £60/year. At £250k you save £285/year. The longer the accumulation horizon, the more this compounds in your favour.
→ Fidelity for larger pots. The same £90 cap logic applies to SIPPs. As pension assets compound over 20–30 years, the custodial saving at Fidelity becomes material. Vanguard suits those who want a simple, low-cost SIPP holding only Vanguard’s LifeStrategy or target-date range and don’t need flexibility.
→ Fidelity. Fidelity charges zero platform fee on ETFs and shares in a general investment account. Vanguard’s 0.15% (with the £48 minimum) still applies in its GIA. For investors who have used their ISA allowance and are investing beyond it, Fidelity’s GIA structure is significantly more cost-efficient at every portfolio size.
→ Fidelity. Vanguard doesn’t offer third-party funds at all. If you want a core Vanguard tracker alongside an actively managed fund, an investment trust, or a specialist ETF from another provider, Fidelity is the only option of the two. You can hold Vanguard funds within Fidelity without needing a second account.
→ Vanguard. If your portfolio is in this range, you invest exclusively in Vanguard’s own funds, and you use batch dealing (free), Vanguard’s 0.15% is competitive. The key assumption: you’re certain you don’t need anything outside Vanguard’s range, and you’re comfortable with the £48/year minimum on smaller pots within that range.

Frequently asked questions
Can I buy Vanguard funds on Fidelity UK?
Yes. Fidelity’s open-architecture platform carries Vanguard’s UCITS fund range alongside thousands of other providers. If you want Vanguard’s passive index funds but also want access to third-party products — or prefer Fidelity’s fee structure — you can hold Vanguard ETFs and funds within a Fidelity account without needing a second platform. This is the main reason some investors choose Fidelity even when they primarily invest in Vanguard index trackers.
Which is cheaper for a small portfolio — Fidelity or Vanguard UK?
Neither is automatically cheaper for small portfolios — it depends on account type and trading frequency. Vanguard’s £4/month minimum (£48/year) applies to all accounts under £32,000, making it more expensive than the 0.15% headline rate suggests for small pots. Fidelity has no minimum: a £10,000 ISA costs £35/year in platform fees (0.35%) versus Vanguard’s £48. But add Fidelity’s ETF dealing fees (£7.50 per trade, or £1.50 via regular savings) and the comparison shifts depending on how often you invest.
Is Vanguard UK only good for passive investors?
Effectively yes. Vanguard’s platform only carries Vanguard’s own range of approximately 85 funds and ETFs. There are no individual stocks, no third-party fund managers, and no investment trusts available. Vanguard does offer some active funds within its own range, but the platform is fundamentally designed for passive, index-based investing. If you want any flexibility beyond Vanguard’s own products — a different manager, a specialist ETF, or individual shares — you’ll need a different platform.
Which is better for a Stocks and Shares ISA?
It depends on what you hold and how much. Fidelity’s ISA caps the annual service charge at £90 for ETF and share holders — above roughly £25,700 this becomes the decisive cost advantage. At £100,000 you pay £90 versus Vanguard’s £150. At £250,000 it’s £90 versus £375. For fund (OEIC/unit trust) investors at Fidelity, the cap doesn’t apply and you pay 0.35% uncapped. Vanguard suits investors in the £32k–£60k range who only want Vanguard’s own products and can use batch dealing to avoid ETF dealing fees entirely.
Can I transfer my ISA from Vanguard UK to Fidelity?
Yes, ISA transfers between UK providers are a standard process. You initiate the transfer through the receiving platform — in this case, Fidelity. Your ISA tax-free status and remaining allowance are fully preserved. The transfer may be completed in-specie (your ETFs move across without being sold) or via cash depending on compatibility between the two platforms. The process typically takes a few weeks. Confirm what Fidelity can receive directly from Vanguard before initiating, and don’t sell your holdings yourself — an ISA transfer must be done formally to preserve the wrapper.
