Fidelity Personal Investing Fees 2026: Full Platform Cost Breakdown

Fidelity's service fee is percentage-based and tiered. The FCA's guide to investment platforms explains what to look for in platform charges. For most investors, the headline number applies — but there are breakpoints that reward larger portfolios:

• Less than £25,000 (with a regular savings plan): 0.35%
• Less than £25,000 (no regular savings plan): £90 flat fee (£7.50/month)
• £25,000 to £249,999: 0.35% of total value
• £250,000 to £999,999: 0.20% — and you qualify for Wealth Management benefits
• £1,000,000+: 0.20% on the first £1 million, nothing above. Capped at £2,000/year

The service fee is calculated across all your accounts combined, not per wrapper — a £200,000 ISA plus a £100,000 SIPP gets the £300,000 fee tier (0.20%), not two separate 0.35% bills. That's a meaningful detail Fidelity buries in the small print.

The small flat-fee option for sub-£25,000 accounts without a regular savings plan is a trap. £90 a year on a £10,000 pot is 0.90% — three times the percentage rate. Set up a £25/month regular savings plan and you drop to 0.35% (£35) automatically. Anyone who doesn't is paying nearly £55 a year for nothing.

Fund dealing on Fidelity is free. No charge to buy, sell, or switch — and that is the single most important fact in this article for fund-only investors.

Share dealing is a different platform underneath:

• Regular savings plan, dividend reinvestment, or income reinvestment: £1.50 per trade
• Online share trades: £7.50 per trade
• Phone trades: £30 per trade

For exchange-traded investments (shares, ETFs, investment trusts) held in an ISA or SIPP, the 0.35% service fee is capped at £7.50/month — £90 a year. Junior ISA, Junior SIPP, and exchange-traded investments held in a standard Investment Account carry no service fee at all.

The £7.50 online share rate puts Fidelity behind AJ Bell (£5) and Interactive Investor Core (£3.99) but ahead of Hargreaves Lansdown (£11.95). If you trade individual shares more than two or three times a year, you're paying for the wrong platform.

Foreign exchange charges matter for investors holding US or international shares. Fidelity tiers FX: 0.75% on the first £10,000 of a trade, 0.50% on £10,000–£20,000, and 0.25% above. A £15,000 dollar conversion costs £100 in FX alone — before the £7.50 trade fee — so the effective spread on small US share trades approaches 1%.

See the iWeb Share Dealing Fees 2026 breakdown if minimising trading costs is your primary criterion.

Fidelity applies the same tiered service fee to SIPPs as it does to ISAs — 0.35% up to £250,000, then 0.20%. There's no separate SIPP wrapper charge, and no annual admin fee for capped or flexible drawdown.

At a £100,000 pension pot, the annual cost is £350. At £250,000 it drops to £500 (the 0.20% tier kicks in at exactly £250k). Free flexi-access drawdown, uncrystallised funds pension lump sums (UFPLS), tax-free cash, and transfers in/out — all included.

The pension annual allowance for 2025/26 remains £60,000, and for higher earners with adjusted income above £260,000 it tapers down to a £10,000 floor. For higher-rate taxpayers maximising contributions, your SIPP can grow through Fidelity's fee tiers in 6–10 years even before market returns.

Here's the uncomfortable maths for SIPP holders: Fidelity's 0.35% on £100,000 is £350, and ii Plus charges a flat £179.88 for the same pot — Fidelity costs nearly twice as much. The premium buys you better tools and Fidelity's own ultra-cheap index funds (Fidelity Index UK at 0.06% OCF, Fidelity Index World at 0.12%), but it doesn't buy you anything ii Plus doesn't also offer at index-fund prices.

Interactive Investor charges a flat fee. Fidelity charges a percentage. That difference creates a single crossover point — and above it, ii is mathematically cheaper.

ii Core costs £5.99 a month — £71.88 a year — with free regular investing and a £100,000 portfolio limit. ii Plus costs £14.99 a month (£179.88 a year) with no portfolio cap, free family Junior ISAs, one free monthly trade, and £1.49 fund deals. Per ii's published charges, pension administration is bundled into the monthly fee — not added on top.

The arithmetic:

• ii Core breakeven vs Fidelity 0.35%: 0.0035 × P = £71.88 → P = £20,537
• ii Plus breakeven (above £100k portfolio limit on Core): 0.0035 × P = £179.88 → P = £51,394

Below about £20,500, Fidelity wins. Between £20,500 and £100,000, ii Core wins. Above £100,000, you're forced onto ii Plus and Fidelity's 0.35% catches up briefly — but only up to £51,400, and crucially, anyone with a £100,000+ portfolio is already past that. Above £100k, ii Plus is always cheaper than Fidelity on platform fee alone.

The £2,000 Fidelity fee cap at £1 million doesn't close the gap. ii Plus on a £1 million pot still costs £179.88 — a £1,820 annual saving every year. Over 20 years of compounding (assuming the saved fee is reinvested at 5%), that's roughly £63,000 of foregone returns at Fidelity.

What the comparison ignores: Fidelity has free fund dealing; ii Core charges £3.99 per fund trade. If you ad-hoc-trade rather than using free regular investing, ii Core's effective annual cost rises by £40–£50 for a typical 12-trade-a-year buyer — which pushes the crossover up to roughly £34,000. Use ii's free regular investing instead and the £20,500 number stands.

Two scenarios that cover most readers — a typical ISA-maxer and a mid-career SIPP saver. All numbers assume monthly contributions via free regular investing, fund-only portfolios, no ad-hoc share trading.

Scenario 1 — £20,000 stocks & shares ISA (one allowance maxed)

Platform	Annual platform fee	Notes
Fidelity (with RSP)	£70	0.35% × £20,000, free fund deals
ii Core	£71.88	£5.99/month, free regular investing
AJ Bell	£42	0.25% capped at £3.50/month for ISA
Hargreaves Lansdown	£70	0.35% on funds

At this size, Fidelity is competitive — within £2 of ii Core and identical to HL on funds. AJ Bell is the cheapest because of its £3.50/month ISA cap. Fidelity's edge here is platform polish; the cost difference is within rounding.

Scenario 2 — £100,000 SIPP (mid-career saver)

Platform	Annual platform fee	Annual saving vs Fidelity
Fidelity	£350	—
ii Plus (forced — Core caps at £100k)	£179.88	£170
AJ Bell	£250	£100
Hargreaves Lansdown	£450	-£100 (more expensive)

At £100,000, Fidelity costs £170 a year more than ii Plus. Reinvested for 20 years at 5%, that compounds to roughly £5,900 of retirement savings. The gap is real — and it widens linearly with portfolio size because Fidelity's percentage keeps charging while ii's flat fee doesn't.

Scenario 3 — £250,000 blended (£150k ISA + £100k SIPP)

• Fidelity: 0.20% × £250,000 = £500
• ii Plus: £179.88 (covers all accounts)
• Annual saving on ii Plus: £320

Fidelity's 0.20% tier kicks in at exactly £250,000, but ii Plus is still £320 cheaper on the same combined balance. The Wealth Management Service benefit Fidelity throws in at this tier is mostly access to its in-house advisers — useful if you want hand-holding, irrelevant if you don't.

Cost isn't the whole story — and Fidelity charges more than the cheapest platforms because the product is meaningfully better in places.

The research and tools are genuinely useful: analyst ratings, fund comparison engines, retirement calculators backed by MoneyHelper guidance, and a Select 50 list of professionally screened funds. The mobile app is competitive with Hargreaves Lansdown's and several rungs above iWeb's bare-bones interface.

Fidelity's own index fund range is the quiet superpower. The Fidelity Index World Fund charges 0.12% ongoing. The Fidelity Index UK Fund charges 0.06%. These are among the cheapest tracker funds available to UK investors — undercutting Vanguard's UK domestic equivalent in places. If you build a portfolio purely from Fidelity's own index range plus a couple of bond funds, your underlying fund costs sit around 0.15% — meaning the all-in cost (platform + fund) is roughly 0.50%.

Junior ISAs and Junior SIPPs carry no service fee, and exchange-traded investments held in a standard Investment Account carry no service fee either — only dealing charges. For families investing across multiple accounts, the no-fee Junior wrappers are a genuine cost edge.

The weakness is the cost ceiling. Fidelity has no flat-fee option above £25,000 — the percentage just keeps charging. ii's £14.99/month Plus plan, by comparison, doesn't change whether your portfolio is £100,000 or £5 million. For investors with multi-decade compounding ahead of them, that structural difference matters more than tools.

Fidelity is the right platform if you fit one of three profiles: you invest primarily in funds inside an ISA and your portfolio sits between £25,000 and roughly £100,000; you have a Junior ISA or Junior SIPP for a child (no service fee); or you specifically want Fidelity's own index funds at 0.06%–0.12% OCF and value the consolidation of holding everything on one platform.

It's also strong for families wanting to manage adult ISAs, SIPPs, and children's wrappers in one login — the no-fee Junior accounts plus the unified Cash Management Account model is genuinely well-designed.

Fidelity is the wrong platform if any of these apply:

• Your portfolio is above £100,000, where ii Plus's £180 flat fee beats Fidelity's percentage by £170+ a year and the gap only grows.
• You're primarily a share dealer. £7.50 per online trade plus a 0.35% platform fee on the underlying value is dramatically more than ii Core's £3.99 or iWeb's £5 flat-fee model.
• You're below £20,000 without a regular savings plan, where the £90 flat fee is genuinely poor value — set up a £25/month direct debit to drop onto the 0.35% percentage tier instead.
• You're investing for the very long term in a single large wrapper. Fidelity's £2,000 cap at £1 million sounds generous until you compare 20 years of £2,000 vs 20 years of £180 — Fidelity costs roughly £36,000 more in nominal fees alone over that horizon.

For most UK investors building a fund portfolio of £20,000 to £100,000, Fidelity is the comfortable middle option — better tools than iWeb, cheaper than Hargreaves, free fund dealing throughout. Above £100,000, the maths starts to argue for Interactive Investor instead — and the bigger your pot, the louder that argument gets.
