What is the lowest-fee UK SIPP for a £100k pot?

As of August 2026, the lowest annual platform fee at a £100k balance among the 19 SIPP platforms Feefee tracks is Trading 212 at £0/yr. Fund costs are separate. The live table at feefee.money/sipp-comparison shows computed costs at £100k, £250k and £500k with a source link per provider. Illustrative comparison data, not a recommendation.

How does Feefee rank SIPP platforms?

Mechanically, by computed annual platform fee at each balance point (£100k, £250k, £500k), lowest first. Rankings are unaffected by commercial relationships. The output is illustrative comparison data, not personal financial advice or a recommendation.

Do the SIPP fees shown include fund costs?

No — the figures are platform fees only. Fund or ETF ongoing charges (OCF/TER) are separate and additive; a low-cost global tracker typically adds around 0.07–0.22% on top of the platform charge.

Is the Trading 212 SIPP included in the comparison?

Yes. Trading 212's SIPP is generally available and carries no platform, custody or dealing fee — Trading 212 runs the pension itself since its February 2026 FCA authorisation, so there is no operator or trustee charge. The only trade-level cost is a 0.15% FX fee on non-GBP trades. It sits among the £0-platform-fee options in the table.

SIPP comparison · UK platform fees

A Self-Invested Personal Pension (SIPP) lets you hold a wide range of investments — funds, ETFs, shares — inside a pension wrapper and claim tax relief on contributions. Platform fees are charged on top of underlying fund costs; comparing the two separately matters.

Fee structures split into two camps: percent-of-portfolio (common at smaller balances — Vanguard 0.15%, AJ Bell Dodl 0.15%) and flat monthly/annual(better for large pots — Interactive Investor Plus £14.99/mo). The crossover point moves with your balance: above roughly £120k, II Plus's flat £180/yr undercuts Vanguard's 0.15% = £180/yr — they tie at that exact level.

Notable dynamics: Vanguard caps at £375/yr — so at £250k+ the effective rate falls below 0.15%. InvestEngine went free on DIY SIPPs in Dec 2025. HL cut from 0.45% to 0.35% on the first £250k in March 2026. Trading 212's SIPP went generally available in 2026 at 0% platform fee, joining InvestEngine at the free end of the table.

Crossover maths

Percent-fee and flat-fee providers swap cost-rank as balances grow. Key breakpoints (platform fee only, rounded to nearest £1k):

II Core cheapest vs Vanguard above ~£48k
II Core £71.88/yr vs Vanguard 0.15%: crossover at £71.88 ÷ 0.0015 ≈ £47,920.
II Plus ties Vanguard & AJ Bell Dodl at ~£120k
II Plus £179.88/yr vs 0.15% fee: £179.88 ÷ 0.0015 ≈ £119,920. Above this, II Plus wins over both.
Vanguard cap kicks in at £250k
Vanguard 0.15% = £375/yr at £250k and stays there. AJ Bell Dodl (no cap) keeps rising — II Plus still cheapest.
AJ Bell (full) cheaper than HL above £250k
HL: 0.35% to £250k + 0.25% above. AJ Bell: 0.25% to £250k + 0.10% above. At £500k: HL = £1,500, AJ Bell = £875.

These are illustrative crossover points using May 2026 fee data. If you hold both a SIPP and an ISA on the same platform, flat-fee plans covering multiple wrappers (e.g. II Plus) can be even better value — run your own numbers using Feefee's onboarding tool.

Advisory / advised platforms

These bundle ongoing financial advice + platform + fund cost. All-in fees are materially higher than DIY platforms; the value proposition is the adviser relationship.

Methodology

Platform fee only. Fund / ETF ongoing charges (OCF / TER) are separate and not shown here. A low-cost global tracker typically adds 0.07–0.22% on top of the platform charge.
Tiered providers. For tiered-percent structures (AJ Bell, HL, Fidelity, Moneybox), the table shows actual £/yr cost at each balance — not just the headline first-tier rate.
Not advice. Choosing a SIPP involves more than the platform fee — fund range, drawdown options, transfer speed, customer service. Rates change; always confirm on the provider's own site.
