Quick Answer
Yes, now is a good time to transfer to Interactive Investor. The current Summer cashback offer (1 August – 30 September 2026) gives you £100–£3,000 cashback on a new SIPP or £150 in free trades on an ISA — and it stacks with the 6-month free referral offer when the bonus account is your first ii account, opened via the referral link. That's the best combined deal available in 2026 so far.
The previous Spring offer (tiered transfer cashback up to £3,000) was larger but ended on 30 April. Offers of that size are rare and typically run once or twice a year. If you missed it, the current deal is still strong — especially when stacked with the referral offer.
If you can wait until late 2026, ii may run another large transfer cashback promotion (historically they've done one in Spring and one in Autumn). But the current deal is guaranteed, and 6 months free on your platform fee is available immediately via the referral link.
Interactive Investor Offers Timeline — 2026
Expected: Autumn Transfer Cashback
ii has run a large tiered transfer cashback offer similar to the Spring 2026 promotion in previous Autumns. If it returns, expect:
- £100–£3,000 cashback, tiered by transfer amount
- Available on SIPP and ISA transfers
- No referral or 6-months-free component (separate scheme)
- However: This is speculative — ii may not repeat the offer, and it cannot be stacked with the referral offer (they're different schemes)
Our take: The Autumn cashback is larger but only available on transfers of £100,000+. For smaller portfolios the current Summer offer (stacked with 6 months free) is likely the better deal. If you're transferring a large SIPP, waiting could pay off — but there's no guarantee the offer returns.
Summer Cashback Offer: £3,000 SIPP / £150 ISA
The current promotion. New customers choose one of two bonuses:
- £100–£3,000 cashback when opening a new SIPP (tiered by transfer/deposit amount)
- £150 in free trades when opening a new ISA or Trading Account
✅ This stacks with the 6-month free referral offer
Use a referral link when signing up to get 6 months free platform fees, then claim your Summer bonus on top. Total value: up to £3,090 (£90 referral + £3,000 cashback) for a large SIPP, or £240 for an ISA (£90 referral + £150 free trades).
Spring Transfer Cashback (Up to £3,000)
The previous tiered cashback offer for transferring an existing ISA or SIPP to Interactive Investor:
| Transfer Amount | Cashback |
|---|---|
| £20,000 – £49,999 | £100 |
| £50,000 – £99,999 | £150 |
| £100,000 – £249,999 | £250 |
| £250,000 – £749,999 | £500 |
| £750,000 – £999,999 | £750 |
| £1,000,000 – £1,999,999 | £1,000 |
This offer was not stackable with the referral offer. It has not been renewed and is listed here for historical reference only.
Should You Transfer Now or Wait?
Transfer Now If…
- Your portfolio is under £100,000 (the tiered cashback wouldn't beat the referral + Summer stack)
- You want a guaranteed deal — the Summer offer ends 30 September, and the referral 6 months free is available right now
- You're opening an ISA or SIPP and the flat-fee structure saves you money (portfolios above ~£20,600 vs HL)
- You can't predict when an Autumn cashback will appear (or if it will at all)
Wait If…
- You're transferring a large SIPP (£250k+) — a tiered cashback of £500–£3,000 could outweigh the current deal
- You missed the Summer deadline and want to see what Autumn brings
- Your current platform is cheap and you're happy with it
- Important: If you wait past 30 September, you lose the current stackable Summer bonus — the referral offer's 6 months free remains available at any time, but the Summer cashback/free-trades bonus ends on that date
How Interactive Investor Promotions Work
Understanding the pattern helps you time your transfer.
The Referral Offer (Always Available)
6 months free platform fees — this is a permanent program. It doesn't expire. You get it by signing up through a referral link and depositing £5,000+ within 12 months. It's separate from cashback offers and can usually be stacked with them.
This is the baseline: whatever cashback offer is running, you always get 6 months free on top via the referral link.
Cashback Offers (Seasonal)
- Run roughly twice a year (Spring and Autumn)
- Usually tiered by transfer amount (£100–£3,000)
- Last 6–8 weeks, then typically not renewed
- Generally NOT stackable with the referral offer
Seasonal Promotions (Newer)
- Smaller but simpler fixed-value offers (like the Spring £200/£100 promotion)
- These ARE stackable with the referral offer
- Seem to be a new format from ii for 2026
- The current Summer offer (30 September deadline) combines a tiered SIPP cashback (£100–£3,000) with the stackable £150 ISA free-trades bonus
