Included and excluded costs

Included

  • Account/platform charges
  • Fund purchases

Explicit exclusions

  • Bid–ask spreads, taxes, regulatory levies, fund ongoing charges, market-data subscriptions, margin interest, cash interest and investment performance are outside the v1 fee model.
  • Provider-specific charges outside the selected activity may apply; a calculated zero is not a claim that the account is free to use.
  • The selected fund, its ongoing charge figure, initial charge and any fund-specific transaction-fee eligibility are not modeled.

Eligibility and coverage

10 covered brokers were evaluated. 2 have mutually comparable modeled calculations; 5 have a material calculation gap; 2 have unknown eligibility; and 1 are ineligible for a selected requirement. Not every broker in the market is covered.

Why 1 covered broker is ineligible
  • InvestEngine: The official product scope explicitly excludes this investment type.

Modeled fee categories: Account, Fund purchases.

Why the modeled charges differ

Percentage platform charges grow with the modeled portfolio value, while a per-purchase charge depends on the fixed count of 12 fund purchases.

  • account lines: The account-charge line applies each calculable platform rule to the £50,000 modeled average value, including published minimums or caps where modeled.
  • fund purchases lines: The fund-purchase line repeats a calculable per-purchase rule 12 times; fund-specific charges that need a named fund remain incomplete.
