Interactive Investor SIPP cashback: £200 offer (2026)

If you are looking for the latest Interactive Investor offers, you are in the right place. Interactive Investor (ii) is one of the UK’s largest investment platforms, best known for its flat monthly fee model rather than percentage-based charges.

For new customers, ii is currently running two offers, both open from 1 August to 31 October 2026: £100 to £3,000 cashback on a new SIPP (pension), depending on how much you transfer or pay in, and £150 of free trades on a new ISA or Trading Account. Both are for UK residents only, and both are for people who are not already ii customers. Here is exactly how each one works, who qualifies, and the conditions worth knowing before you open an account.

Interactive Investor offers at a glance

Interactive Investor SIPP cashback explained

The headline offer is cashback of £100 to £3,000 when you open a new ii Personal Pension (a SIPP, or Self-Invested Personal Pension) and fund it with at least £20,000. The more you transfer or contribute, the bigger the cashback:

It is the more valuable of the two offers for larger pensions, but it also comes with the most strings, so it is worth understanding the qualifying criteria in full.

Who is eligible

• You must not have been an existing ii customer on or before 31 July 2026.
• You must be over 18 and a UK resident, living at a UK address when you meet the qualifying criteria.
• The ii SIPP must be your first ii account, opened between 1 August and 31 October 2026.

How to qualify for the cashback

1. Open a new ii Personal Pension as your first ii account during the offer period.
2. Fund it with at least £20,000 in total. This can be done through a pension transfer from another provider (which must complete within 6 months of you submitting the instruction), a cash contribution, or a combination of the two.
3. Add an ii Trading Account to your SIPP within 6 months of the end of the offer period. This is the account the cashback is paid into.

One important exclusion: cash or investments you already hold in an ii account (or with any company in ii’s group) do not count towards the £20,000. The qualifying funds have to be new money or a genuine transfer from another provider.

When and how the cashback is paid

The cashback is paid into the ii Trading Account linked to your SIPP. ii credits it by the later of two dates: 30 days after you meet the qualifying criteria, or 30 days after you open the Trading Account. It is a maximum of one payment per person, although ii can split it into instalments at its discretion. The cashback is funded by ii and is not taken from your investments.

The 12-month minimum term (read this before transferring)

To keep the cashback, you need to keep your ii SIPP open and funded for at least 12 months from the date your last qualifying transfer or contribution completes. If you close the SIPP, or withdraw or transfer the qualifying money out before that 12 months is up, ii can reclaim the cashback.

Interactive Investor £150 free trades (ISA and Trading Account)

The second offer is lower value but also far simpler, with no minimum deposit. New customers who open an ii Stocks & Shares ISA and/or an individual Trading Account (a General Investment Account, or GIA) as their first account during the offer period receive £150 of trading credits.

• Eligibility: new ii customers only, over 18 and UK resident.
• Minimum deposit: none.
• When credits arrive: within 5 working days of your account being opened.
• Expiry: the credits can be used until midnight on 31 December 2026. Anything unused after that expires.

The credits can be used to offset commission on real-time trades when you buy or sell shares, funds, bonds, gilts and ETFs, as well as automated trades such as dividend reinvestment. They cannot be used for the extra charges on extended settlement or telephone trades, or inside an ii Managed ISA, ii Managed Portfolio or ii360. New accounts start on ii’s Core plan (£5.99 a month). If your combined ISA and Trading Account balance goes above £100,000, you move to the Plus plan (£14.99 a month).

What £150 of credits buys: on the Core plan, UK and US share, ETF and fund trades cost £3.99 each, so the credits cover about 37 trades. They do not cover the £5.99 monthly plan fee, foreign exchange (0.75% on Core) or the £0.99 dividend reinvestment charge per holding.

One small timing note: orders placed before the expiry date but executed after it will not be eligible for the credits. Since fund orders often settle a few days after you place them, do not leave fund purchases until the last moment in December.

Is the Interactive Investor offer worth taking?

For the £150 free trades, the answer is straightforward. There is no minimum deposit and effectively no lock-in beyond the credit expiry, so if you were going to open an ii ISA or Trading Account anyway, it covers your first trades. Remember that the £5.99 monthly fee still applies from day one.

The SIPP cashback deserves more thought, because moving a pension is a bigger decision than the cashback itself. ii’s flat-fee model tends to work best for larger pension pots, where a fixed monthly charge beats a percentage fee. If you were already planning to consolidate a pension into a flat-fee SIPP and you can comfortably meet the £20,000 funding requirement and the 12-month minimum term, the cashback is a genuine bonus on top. For example, a £60,000 transfer earns £150, roughly 25 months of the Core plan fee.

What you should not do is transfer a pension purely to claim the cashback. Before transferring, check whether your existing pension has exit fees or valuable benefits you would lose, such as guaranteed annuity rates, a lower protected pension age or matching employer contributions. If you are over 50, Pension Wise offers free, impartial guidance. As ii itself states in the terms, the offer is not advice or a recommendation to transfer, and if you are unsure whether transferring is right for you, you should take independent financial advice.

Other broker bonuses

If an ii account is not quite what you are after, several other platforms run sign-up offers for UK investors:

Trading 212: open an account with code IITW and you get a free fractional share. Odds: 80% for a share worth 8 to 25, 15% for 25.01 to 50, 3% for 50.01 to 75 and 2% for 75.01 to 100 (in your account currency). See the promo code terms and our Trading 212 promo code guide. Trading 212 offers investing with no commission (other fees may apply, see terms and fees). A 0.15% FX fee applies when converting funds. Other fees may apply. When investing, your capital is at risk and you may get back less than invested. Past performance doesn’t guarantee future results.

Is Interactive Investor safe and regulated?

Yes. Interactive Investor Services Limited is authorised and regulated by the Financial Conduct Authority (FCA), and eligible client investments are protected under the Financial Services Compensation Scheme (FSCS) up to £85,000 per person. ii has been around for 30 years, has more than half a million customers and its registered office is at 201 Deansgate, Manchester, M3 3NW. The FSCS covers you if the firm fails, not if your investments fall in value.

Bottom line

Interactive Investor has two new-customer offers running until 31 October 2026, both for UK residents. The £150 free trades on a new ISA or Trading Account is simple and low-commitment. The SIPP cashback of £100 to £3,000 is more rewarding for larger pensions but comes with a £20,000 minimum funding requirement and a 12-month minimum term, so it suits people who were already considering a flat-fee SIPP rather than anyone chasing the cashback alone.

Can I get both ii offers?
Each offer requires the account to be your first ii account and you must not be an existing customer, so in practice you qualify for the one that matches the account you open first.

Do I need to register for the offer?
Only if the offer page shows a registration step. Otherwise ii applies it automatically once you meet the criteria.

What happens if I transfer my pension out within a year?
ii can reclaim the cashback if you close the SIPP or move the qualifying money out within 12 months of your last qualifying transfer or contribution.
