Our verdict
Interactive Investor offer a wide range of index tracker funds. A good choice for large index fund portfolios, as they offer good coverage and the fixed-fee model means that the bigger your account size gets, your costs stay the same. You can either pick your own or choose from some featured funds from their Super 60 investment list.
