Interactive Investor* (ii) has launched a major restructuring of its pricing model, which officially came into effect on 1st February 2026. The platform has replaced its previous subscription tiers with three simplified options: Core, Plus, and Premium.
The changes are intended to make investing more straightforward and, for a significant portion of customers, more cost-effective. The most notable shift is the removal of separate fees for different account types. Instead, a single flat monthly fee now covers a Stocks and Shares ISA, a Trading Account (GIA), and a Self-Invested Personal Pension (SIPP).
The change is likely to appeal to investors who hold both an ISA and a pension, as it removes the need to pay additional SIPP fees, something that many other platforms charge.
ii new plan pricing explained
From 1st February 2026, the 'Investor Essentials', 'Investor', and 'Super Investor' plans have been replaced. The new tiers are:
- Core (£5.99 per month) - For those with a combined portfolio of up to £100,000. This is a significant increase from the previous £50,000 limit on the entry-level plan. It includes an ISA, SIPP and Trading Account.
- Plus (£14.99 per month) - For portfolios over £100,000 (or those with less who want the extra benefits). This plan includes one free trade per month, free Junior ISAs for all of your children, and allows you to add up to five friends or family members to your subscription for free.
- Premium (£39.99 per month) - Aimed at frequent traders and high-net-worth individuals. It includes two free trades a month, free fund trading, discounted share trading rates, and unlimited free family accounts. It also offers access to 'ii360', a new advanced trading platform launching in 2026.
Lower trading and FX fees explained
Alongside the plan changes, ii has cut costs for international investing.
- Foreign Exchange (FX) fees - These have been simplified across all plans. Core plan holders will now pay a flat 0.75%. Plus plan holders will pay 0.75% on the first £50,000 and 0.25% thereafter and Premium plan holders pay a flat 0.25%.
- Trading fees - UK and US shares have remained at £3.99 for Core and Plus plan holders, but Premium plan holders now pay just £2.99 per trade. In addition, fund dealing has been reduced to £1.49 on the Plus plan (which is cheaper than Hargreaves Lansdown's new charges) and it is free on the Premium plan.
ii new price plan comparison
According to Interactive Investor, the majority of customers will be better off under the new pricing, particularly those who have consolidated their pensions and ISAs on the platform. The table below highlights how the changes will impact different types of investors.
| Investor Profile | Previous Monthly Cost | New Monthly Cost (Feb 2026) | Monthly Saving / Increase | Annual Saving / Increase |
| ISA / GIA only (Under £50k) | £4.99 | £5.99 | + £1.00 | + £12.00 |
| ISA / GIA only (£50k - £100k) | £11.99 | £5.99 | - £6.00 | - £72.00 |
| ISA / GIA (Over £100k) | £11.99 | £14.99 | + £3.00 | + £36.00 |
| SIPP only (Under £50k) | £5.99 | £5.99 | No change | No change |
| SIPP only (£50k - £100k) | £12.99 | £5.99 | - £7.00 | - £84.00 |
| SIPP only (Over £100k) | £12.99 | £14.99 | + £2.00 | + £24.00 |
| ISA, GIA & SIPP (Under £75k) | £9.99 | £5.99 | - £4.00 | - £48.00 |

How will the new ii price plan changes impact you?
- ii investors with a small ISA or GIA portfolio - Investors with less than £50,000 in an ISA who do not hold a SIPP will see a £1 monthly rise. However, the increased limit of £100,000 gives investors much more room to grow their pot before needing to upgrade their plan, so are likely to be better off in the long run.
- ii investors with a mid-sized portfolio (£50k - £100k) - Previously, investors would have been moved onto the £11.99 Investor plan once they passed £50,000. They can now stay on the cheaper £5.99 Core plan until they hit £100,000, which will result in a significant saving.
- ii investors with a SIPP - Investors with a mid-sized SIPP are likely to be the biggest winners. Previously, holding a SIPP attracted an additional fee or a higher standalone cost. By bundling the SIPP into the flat monthly fee, ii now offers one of the cheapest ways to invest for retirement. However, those with very large SIPP-only portfolios (over £100k) will see a small £2 monthly increase as they move to the 'Plus' plan.
Why has ii introduced a new pricing structure?
The investment platform market has become increasingly competitive in recent years, with fierce competition driving down costs. Hargreaves Lansdown's recent decision to overhaul its pricing is further proof of the growing competition among major UK platforms. Additionally, new 'challenger' investing apps like Trading 212 and Freetrade have disrupted the industry with low-cost or zero-commission models, putting pressure on established platforms to demonstrate value. By bundling ISAs, Trading accounts and SIPPs into a single monthly fee, investors are encouraged to consolidate their wealth in one place, rather than splitting it across multiple providers to save money. The inclusion of free "Friends and Family" accounts on the Plus and Premium plans further encourages customers to bring their partners and children onto the platform, solidifying ii's position as a family-focused provider.
