Interactive Investor pension fees and charges
Direct answer: Interactive Investor charges Core £5.99/mo + £2.50/mo SIPP admin (£102/yr, up to £100k); Plus £14.99/mo + £6.00/mo SIPP admin (£252/yr, no cap); Premium £39.99/mo + £6.00/mo SIPP admin (£552/yr, no cap). On a £100,000 pot that is £102/year in annual provider/platform fee, and on a £500,000 pot it is £252/year. Fund charges and product-specific caveats may apply.
Interactive Investor pioneered the flat-fee model in the UK — you pay a fixed monthly fee regardless of pot size. The SIPP costs the plan fee plus a pension admin fee on top: Core £5.99/mo + £2.50/mo admin = £101.88/year (covers pots up to £100k); Plus £14.99/mo + £6.00/mo admin = £251.88/year (no cap). Even with the admin fee, ii is dramatically cheaper than percentage-fee platforms for larger pots: on a £500,000 pot, ii costs ~£252/year vs Hargreaves Lansdown's £1,500. The breakeven point vs Vanguard is around £150,000–£175,000 once admin is included. ii offers the same breadth of investment choice as HL (3,000+ funds, shares, ETFs) but at a fraction of the cost for bigger portfolios. The main drawback is that for very small pots (under £25,000), the combined fee represents a higher effective percentage than cheaper platforms.
