The decision to publish these details is a UK first, says Fidelity, and Fidelity hopes it will increase transparency.

An average charge of 0.25 per cent is taken by Fidelity for the majority of funds on the network and 90 per cent of funds have a platform fee of 0.25 per cent or less.

Each fund manager is also charged a fee of £600 per fund to list a fund on the FundsNetwork.

The decision follows advice in the recent FSA platform paper that platforms will have to disclose platform fees and remuneration once the RDR is implemented.

However FundsNetwork said it saw no reason why it should wait until 2012 to start disclosing fees.

Ed Dymott, head of commercial at Fidelity, said: “We want to reassure our customers that our pricing policy has a standard approach with no commercial bias. We aim to treat and present all fund groups in the same way.”

“We feel that the industry would be better served through simple disclosure, which as we have evidenced, clearly can show how cost effective platform access can be.”

David White, head of FundsNetwork, said: “We firmly believe that our advisers and their clients should not only understand fully what is being paid on investments so that they can make informed decisions but they should also be able to see clearly, what we as a platform, are receiving as payment from fund providers.”

Previously the information had only been available on request.
