Cofunds has launched its unbundled pricing structure with 1,700 share classes from 85 fund groups.
The 'Explicit Pricing Model' is designed to be transparent and simple and clearly separate the costs of investing.
Features include a fixed annual charge for all basic platform services and no upfront or switching charges. Any switching charges will be covered by the fixed platform charge.
Tiered percentage charges will start at 0.29 per cent per year and reduce to 0.15 per cent for those with assets of more than £10m.

Martin Davis, chief executive of Cofunds, said: "Twelve months ago we pinned our colours to the mast and pledged to bring our new pricing model to market in Q3 2012.
"True to our word, our tiered model that rewards consolidating assets on the platform launched today and did so with overwhelming support for our drive for clean share classes."
The firm is aiming to have 2,000 funds available by the end of the year.
Cofunds was also appointed last week to support the Financial Planning proposition for advisory firm RSM Tenon. RSM Tenon has 65 private client Financial Planners and Cofunds will start work with them later this year.
Cofunds will similarly support the RSM Tenon self-serve proposition for clients with less than £100k in investable assets.
Alistair Conway, sales and marketing director at Cofunds, said: "We're extremely pleased that having carried out extensive platform due diligence, RSM Tenon decided to put their faith in Cofunds to help deliver that service to the same high standard and in the most appropriate way for each client segment."
