The platform allows investors access to more than 2,000 unit trusts and for the 20% of funds it cannot offer without an initial charge it will waive its own charge instead.
This means the only upfront fee for those funds will be the one from the fund manager.
For investors who pay up to 5% in upfront fees with other providers, this represents a significant saving.
In addition JPJShare said it will rebate 0.25% of the trail fees it earns each year (typically 0.5%) to both new and existing customers.
So for a client with £100,000 in funds that would be a rebate of £250.
It will also cap its share of the rebate to £500, so for clients with £500,000 in funds that will be an annual refund of £2,000, while JPJ gets £500.
The group’s SIPPs and ISAs are offered with no set up charges and no transfer in charges and a standard share dealing commission of £5.75 or £4.75 for frequent traders.
JPJ said it was committed to leading the way as an ultra low cost provider of non advisory financial services.
CEO of the firm, Brian Gould, said: "We believe in charging our customers a fair price for all the services we provide.
"The JPJShare tank is parked on the lawns of other firms that do not offer what we believe to be a fair deal to their customers. The challenge is for them to respond."
JPJShare.com is a trading name of Rivington Street stockbrokers and operates from the Isle of Man while offering a service to the UK.
