We spent this session doing something simple: checking whether the fee data published on major UK investment comparison sites matches what the platforms actually charge. The short answer is: often not. We found at least three material errors that would cause a reader to overestimate or underestimate the annual cost of a specific platform — and make a worse decision as a result.
This is our first fee accuracy audit. We plan to repeat it quarterly. All data on this page was checked directly from the relevant platform's published charges page on 28 June 2026. We link to every source.
Finding 1: Hargreaves Lansdown — wrong fee on multiple comparison sites
What several sites show: Hargreaves Lansdown platform fee: 0.45% for shares and ETFs.
What HL actually charges: 0.35% for shares, ETFs, and investment trusts — capped at £150/year per account. We verified this directly from hl.co.uk/charges on 28 June 2026.
Why this matters: On a £50,000 ISA, the difference between 0.45% (£225/year) and 0.35% (£150/year capped) is £75 per year. A reader relying on the incorrect figure would rank HL as less competitive than it actually is.
| Portfolio size | Fee at 0.45% (incorrect) | Actual fee — 0.35% capped at £150/yr | Annual error |
|---|---|---|---|
| £5,000 | £22.50 | £17.50 | £5.00/year overstated |
| £20,000 | £90.00 | £70.00 | £20.00/year overstated |
| £50,000 | £225.00 | £150.00 (cap) | £75.00/year overstated |
| £100,000 | £450.00 | £150.00 (cap) | £300.00/year overstated |
| Source: hl.co.uk/charges — verified 28 June 2026. Cap is per account (ISA, SIPP, and GIA each capped separately at £150/year for shares/ETFs). | |||
The 0.35% rate for shares and ETFs appears to have changed from the 0.45% figure that is still being cited. We cannot confirm exactly when this change was made, but it is visible on HL's charges page as of 28 June 2026. The 0.45% rate still applies to funds (not ETFs/shares) at the top tier — which may explain why some comparison sites are showing the wrong figure for ETF investors.
Finding 2: Fidelity — the ETF cap that changes everything
What most comparison tables show: Fidelity at 0.35% — implying ~£175/year on a £50,000 portfolio and ~£350/year on £100,000.
What Fidelity actually charges for ETFs in an ISA: 0.35%, capped at £7.50/month (£90/year). This cap applies specifically to "any exchange-traded investments, including shares, in an ISA or SIPP." We verified this directly from fidelity.co.uk/services/charges-fees/ on 28 June 2026.
Why this matters: Without this cap, Fidelity appears mid-tier or expensive for large ETF portfolios. With the cap, it becomes one of the cheapest percentage-fee platforms for ISA investors above ~£26,000 — and the second-cheapest paid platform overall at £100,000 (behind only AJ Bell at £42/year).
"Service fee applied to any exchange-traded investments, including shares, in an ISA or SIPP — 0.35% (reduced to 0.20% if you invest £250,000 or more) and capped at £7.50 per month."
— fidelity.co.uk/services/charges-fees/, 28 June 2026
| Portfolio size | Fee at 0.35% (no cap — incorrect for ETFs) | Actual fee — ETF cap at £90/yr | Annual difference |
|---|---|---|---|
| £5,000 | £17.50 | £17.50 | No difference (below cap) |
| £20,000 | £70.00 | £70.00 | No difference (below cap) |
| £50,000 | £175.00 | £90.00 (cap) | £85.00/year overstated |
| £100,000 | £350.00 | £90.00 (cap) | £260.00/year overstated |
| £200,000 | £700.00 | £90.00 (cap) | £610.00/year overstated |
| Source: fidelity.co.uk/services/charges-fees/ — verified 28 June 2026. Cap applies to ETFs, shares, and investment trusts in ISA/SIPP only. Funds (OEICs/unit trusts) have a different fee structure without this cap. | |||
One important nuance: for portfolios under £25,000 without an active regular savings plan (RSP), Fidelity charges a flat £7.50/month (£90/year) regardless of portfolio size — more than 0.35% would be. If you have a direct debit set up (even for a small amount), the 0.35% rate applies. This means Fidelity is genuinely cheap for most investors above £25,000, but the flat fee makes it relatively expensive for very small passive portfolios without a regular savings plan.
Finding 3: AJ Bell — cap confirmed at £42/year
AJ Bell's 0.25% platform fee for shares and ETFs is capped at £3.50/month (£42/year) — confirmed directly from ajbell.co.uk/isa/stocks-shares-isa/charges on 28 June 2026.
The cap kicks in at a portfolio value of approximately £16,800 (0.25% × £16,800 = £42). Above this threshold, the annual cost is flat at £42 regardless of how large the portfolio grows — making AJ Bell one of the best-value paid platforms for larger ETF ISAs.
Some sites do not display this cap at all, showing AJ Bell simply as "0.25%" — which would imply £250/year at £100,000 rather than the actual £42.
Finding 4: interactive investor — old plan data still circulating
Interactive Investor replaced all three of its legacy plans on 1 February 2026. The old plans — Investor Essentials (£4.99/month), Investor (£11.99/month), and Super Investor (£19.99/month) — are discontinued. We have seen these figures still appearing on some comparison pages.
Correct current pricing (verified from ii.co.uk/our-charges): Core at £5.99/month (£71.88/year), Plus at £14.99/month, Premium at £39.99/month. The Core plan now includes ISA + SIPP + Trading Account — the old Investor Essentials at £4.99 did not include a SIPP, which is a material change.
Finding 5: XTB — largely absent from major comparison tables
XTB (FCA FRN 522157) offers a Stocks and Shares ISA with no platform fee and zero commission on ETF and share trades up to €100,000/month. We verified this from xtb.com/en/account-and-fees on 28 June 2026.
XTB is absent from the majority of established comparison tables we reviewed, despite being directly comparable to Trading 212 and Lightyear on fee structure. It does not currently offer a SIPP. XTB also pays 4% AER on uninvested cash (standard rate; promotional rates vary for new accounts).

Our methodology
How we verified this data
- We fetched the relevant charges or fees page directly from each platform's own website — not from third-party aggregators or cached sources.
- We extracted the specific figures for exchange-traded investments (ETFs, shares) in an ISA, which is the focus of our comparison. Where platforms charge differently for funds vs. ETFs, we show the ETF rate.
- We recorded the source URL and the date of verification for each platform. All data on this page was verified on 28 June 2026.
- Where a figure was quoted from a text table on the platform's page, we quote the exact language used in the source.
- We compared our verified figures against what is shown in the comparison tables of several major UK financial comparison sites and noted discrepancies.
