Does it stack with the referral?
Yes, they stack. Join through our referral link and you can also get ii's separate £100–£5,000 cashback (until 30 November 2026). ii's written terms don't mention combining them, so check with ii if you want it confirmed.
- ii: don’t transfer just to qualify, and don’t rush a decision to meet the deadline. Before moving a pension, check exit fees and any guarantees you'd lose.

Every referral rule that decides whether you qualify
Summarised from ii's Recommend ii terms (effective 1 June 2026). The full terms take precedence.
| You get | No monthly account fee (or SIPP fee) for 6 months: worth £35.94 on Core or £89.94 on Plus. Starts within 10 working days of qualifying. |
|---|---|
| Who | New ii customers only, aged 18+ and resident in the UK. Personal accounts, not accounts in the name of a company or trust. You can't refer yourself. |
| How to open | Through the referrer's unique link. There's no code, and accounts opened any other way don't qualify. |
| Eligible accounts | Stocks & Shares ISA, Managed ISA, Personal Pension (SIPP), Trading Account |
| Funding | £5,000 in total, by cash deposit or transfer from another provider, completing within a year of opening. Anything that completes later doesn't count. |
| Opening a SIPP | The minimum must be paid or transferred into the pension, not into another account. |
| Plans | Core or Plus. Upgrading to Premium ends the fee-free period, and moving back to Core or Plus doesn't restart it. |
| Before you qualify | Normal charges apply until the £5,000 condition is met. |
| During the free months | Dealing and all other charges still apply. Plan trading credits (such as Plus's monthly free trade) don't apply. |

- The reward is paid into your Trading Account within 30 days of your friend qualifying, or of adding your Trading Account if that’s later.
- One reward per friend, however many accounts they open.
- ii can reclaim it if your friend's account is closed or transferred out within 12 months.
Quick answers
Current ii offers: questions
More on the referral FAQ and transfer timing pages.
What is the best Interactive Investor offer right now?
ii publishes two separate offers. The referral gives 6 months with no monthly account fee on Core or Plus if you open through a referral link and add or transfer £5,000 within a year; it has no published end date. Until 30 November 2026, new customers can also get £100–£5,000 cashback on a new SIPP, ISA or Trading Account (minimum £20,000 across your new accounts). They stack with the referral. Capital at risk.
Is there an ii referral code?
No. There’s no ii referral code: open through a referral link and add or transfer £5,000 within a year to get 6 months with no account fee on Core or Plus. The cashback doesn’t use a code either.
What is the ii cashback offer in November 2026?
£100 to £5,000. Open a new ii SIPP, ISA, Managed ISA or Trading Account between 1 and 30 November 2026 (not an ii customer on or before 31 October 2026) and transfer or pay in at least £20,000 in total across your new accounts. Cashback runs from £100 (£20,000–£49,999.99) to £5,000 (£3 million or more), one payment per person, paid into an ii Trading Account. Keep the accounts open and funded for 12 months or ii can reclaim it.
Can I combine the ii referral with the cashback?
Yes, they stack. Join through our referral link and you can also get ii's separate £100–£5,000 cashback (until 30 November 2026). ii's written terms don't mention combining them, so check with ii if you want it confirmed.
Does ii still offer free trades for new customers?
Not as a new-customer offer. The £150 free-trades offer ended on 31 October 2026 (credits already given are usable until 31 December 2026). ii’s current offer is cashback instead. Plus includes 1 free trade a month and Premium 10.
What happens after 30 November 2026?
The cashback offer ends unless ii extends it. The referral offer has no published end date, though ii can change or withdraw it without notice. We update this page after checking ii.co.uk/special-offers.
