Interactive Investor referral FAQ

Open a new ii account through a referral link and add or transfer at least £5,000 within a year; ii then charges no monthly account fee for 6 months on Core or Plus. That’s £35.94 saved on Core or £89.94 on Plus (Premium isn’t covered). It works for a Stocks & Shares ISA, SIPP, Trading Account or Managed ISA. Opening by 30 November 2026? ii’s separate £100–£5,000 cashback can apply too, but it needs at least £20,000.

No. There’s no ii referral code: ii uses referral links, not codes, so there’s nothing to type in, and it can’t be added afterwards. Open through a referral link and add or transfer £5,000 within a year, and ii waives the monthly account fee for 6 months on Core or Plus. See There is no Interactive Investor referral code, then use our ii referral link when you open the account.

No. ii’s current new-customer offers don’t use promo or discount codes. The refer-a-friend offer works through a referral link (six months without the monthly account fee on Core or Plus).

£5,000 in total, by cash deposit or transfer from another provider, added up across your new accounts. It has to complete within a year of opening; money that arrives later doesn’t count. If you open a SIPP, the £5,000 must be paid or transferred into the pension, not another account.

Stocks & Shares ISA, Managed ISA, Personal Pension (SIPP) and Trading Account, for new ii customers aged 18+ and resident in the UK, in their own name (not company or trust accounts). The fee-free period covers Core and Plus only. Upgrading to Premium ends it, and moving back to Core or Plus doesn’t restart it.

Within 10 working days of meeting the £5,000 condition. It covers the monthly account fee (or SIPP fee) for six months. Dealing charges still apply, and plan trading credits, such as Plus’s monthly free trade, don’t apply during those months.
