Interactive Investor SIPP fees: ii's price list shows a flat monthly plan fee from £5.99, plus dealing charges. Here is each charge and how to weigh it.
Interactive Investor (ii) says it charges for its SIPP through a flat monthly fee, not a percentage of the pot. The charges below are from its own price list (PDF last updated 1 October 2026; web pages read 19 October 2026), followed by our arithmetic on those figures and what else to check. Whether these charges suit your own pot turns on your whole position, which a phone conversation with an FCA-authorised adviser firm can cover. Asking costs nothing, and the route is the form on this page.
The monthly plan fee
ii's rates and charges PDF says "We offer 3 simple plans, each with a fixed monthly fee and trade costs to suit your style of investing." A SIPP can sit on any of them:
| Plan | Monthly fee | Portfolio limit |
|---|---|---|
| Core | £5.99 | Up to £100,000 |
| Plus | £14.99 | Unlimited |
| Premium | £39.99 | Unlimited |
Several points in the price list shape what you actually pay:
- One fee can cover several accounts. A Trading Account, Stocks & Shares ISA, Managed ISA, SIPP and Junior ISAs "held in the same name can be linked together under one plan and monthly fee." The portfolio limit is therefore a limit on your holdings with ii, not on the SIPP alone.
- You start on Core and are moved up. "When you first open an ii account you’ll join on our Core plan. If and when your portfolio value exceeds £100,000, we’ll move you onto our Plus plan." Core also needs a Direct Debit and email communications.
- The fee does not cover dealing. The charges page says the monthly fee "only covers your access to the ii investment platform and services. It doesn’t cover other costs like trading fees and foreign exchange."
- Part of the fee is for pension administration. "This is £2.50 including VAT on Core, £6 including VAT on Plus and Premium." It sits inside the plan fee rather than being added to it.
The same page says "we’ll never take a percentage of your wealth", so the plan fee does not rise with the size of the pot within a plan.
Dealing charges
Dealing charges depend on the plan and on what you buy or sell. These are the per-trade figures from ii's PDF:
| Per trade | Core | Plus | Premium |
|---|---|---|---|
| Funds | £3.99 | £1.49 | Free |
| UK and US shares (including ETFs and investment trusts) | £3.99 | £3.99 | £2.99 |
| Other international shares | £9.99 | £7.99 | £5.99 |
| Dividend reinvestment | £0.99 | £0.99 | Free |
Regular investing is listed as free on every plan. Plus and Premium also carry a monthly trading credit: "£3.99 for Plus, £29.90 for Premium", which "can be used against your trading fees in any of your accounts" and lasts 31 days. Telephone trades are £49 on top of the online commission.
Foreign exchange is charged when you convert currency, either as part of a trade or on its own: 0.75% on Core, 0.75% on the first £50,000 and 0.25% above that on Plus, and 0.25% on Premium.
Other charges and taxes that can apply
Of the PDF's longer "all other charges" list, these are the ones most likely to matter in a SIPP:
- Withdrawals. Next-day payments in sterling or euros have no charge; same-day payments and withdrawals in other currencies are £15, and same-day payments must be requested before 2pm.
- Add-ons. ii360 is "+£20 per month" on Core and Plus and "is included in your monthly Premium plan fee"; ii Advice is "+£100 per month" on Core and Plus.
- Residence and legacy accounts. Non-UK residents pay "£5 per month", and a Pension Trading Account or Investment Club, which ii calls legacy account types, "£50 per month".
- Taxes and levies. UK stamp duty on equity buys is 0.50% and the PTM levy is £1.50 on UK equity buys and sells above £10,000.
Cash interest is published separately; see SIPP interest on cash.
Fund charges are not on ii's price list
The funds you hold carry their own charges, set by the fund managers and separate from the plan fee and dealing charges. ii's own comparison page says its figures are "Pension charges only, excludes fund manager charges." Pension charges and fees explains how fund costs, platform charges and transaction costs fit together, and ii's ready-made SIPP covers its managed option.
Taking an income, and moving in or out
On drawdown, ii's SIPP page says: "There are no charges for taking an income from your pension. It's all covered by your monthly SIPP fee." Money left in a drawdown pot "remains invested", so the plan fee, dealing and fund costs carry on. See how drawdown works and choosing a drawdown provider; anyone approaching retirement can also use Pension Wise, MoneyHelper's free guidance service.
On transfers, the charges page says: "No, we don’t charge any fees for transfers in or out. This includes ‘in specie’ (full) transfers, where you keep the same investments as your old account. But be sure to check for any transfer fees with your existing or new provider." The transfer page says a transfer can be full or partial "provided your current provider allows partial transfers", and that a pension moved entirely as cash "usually takes 2 to 6 weeks". Any exit charge would come from the scheme you are leaving; the rules on those are in pension transfer fees, and the steps are in how to transfer a pension.
The same page warns against losing valuable benefits "such as guaranteed annuity rates, lower protected pension age or matching employer contributions", so what the old plan holds matters as much as the fee. An old plan's terms and a new fee need reading side by side; to have an FCA-authorised adviser read both, begin on the form on this page (nothing to pay).
A flat fee against a percentage charge: the arithmetic
ii's SIPP page says "Other providers usually charge a percentage of your pot. That means you’ll be charged more as your pension grows in value." Which costs less depends on the sums. The table below is our arithmetic on ii's published monthly fees only: each fee times 12, then divided by the pot and rounded to two decimal places.
| Plan | Twelve months (fee × 12) | As a share of a £20,000 pot | of £100,000 | of £250,000 |
|---|---|---|---|---|
| Core (£5.99 a month) | £71.88 | 0.36% | 0.07% | Not available: Core stops at £100,000 |
| Plus (£14.99 a month) | £179.88 | 0.90% | 0.18% | 0.07% |
| Premium (£39.99 a month) | £479.88 | 2.40% | 0.48% | 0.19% |
What the arithmetic shows:
- A flat fee weighs most on a small pot. The same £71.88 is 0.36% of £20,000 and 0.07% of £100,000.
- The step from Core to Plus is sharp. The yearly fee goes from £71.88 to £179.88 when a portfolio is moved above £100,000, which on a pot just over £100,000 is about 0.18% rather than 0.07%.
- Dealing adds to it. Twelve fund trades in a year would be £47.88 on Core (12 × £3.99) and £17.88 on Plus (12 × £1.49) on top of the plan fee, and free on Premium.
The table treats the whole plan fee as the SIPP's cost; if it also covers an ISA or trading account, the cost per account is lower. ii's own pension-charges guide cautions that "depending upon the value of your pension and the number of fund buys / sells or switches the ii SIPP could be more expensive for you."
To compare with another provider, add its platform charge, dealing charges and fund costs for the same pot and number of trades, and set that against ii's total. Our Vanguard, Fidelity and Hargreaves Lansdown fee pages give each firm's own published figures, and what an ii SIPP can hold covers the investment range.
What else to check before you choose
- The date on the price list. Check the live version before relying on any figure here.
- Which plan you would be on. Your total holdings with ii, not only the SIPP, decide whether Core is available.
- How you will invest. Regular monthly purchases give a different bill from frequent trading.
- Promotions. ii's cashback offer for new SIPP customers says it ends 31 October 2026 (read 19 October 2026); the terms are in ii SIPP offers.
- Who contacts you. The FCA advises hanging up on unexpected pension calls; its pension scams page lists the warning signs.
Investments held in a SIPP can go down in value as well as up, so the pot could end up worth less than was put in. See what a SIPP is and the Interactive Investor SIPP.
Interactive Investor SIPP fees: questions people ask
Does Interactive Investor charge to transfer a SIPP out?
ii's charges page says it does not charge fees for transfers in or out, including in specie transfers. The receiving provider may have charges of its own, so check both sides.
Can I transfer only part of my pension to ii?
ii's transfer page says a partial transfer is possible "provided your current provider allows partial transfers". Ask your current provider first.
Are there separate fees for a SIPP and an ISA?
ii's PDF says a SIPP, Stocks & Shares ISA and other accounts in the same name can sit under one plan and monthly fee. Dealing charges and other costs still apply to each account.
Is an ii SIPP better than a Vanguard SIPP?
That turns on pot size, how often you trade and fund costs. Work through both firms' published charges with the method above, starting from Vanguard SIPP fees.
