Private client investment manager Thesis Asset Management has launched self-selecting mini and maxi Isas.
The Isas give investors the choice of investing in any unit trust, corporate bonds or direct equities.
There is a minimum investment requirement of £1,000 for both the mini and the maxi products.
Thesis charges an initial fee of £75, although this is waived if a Thesis unit trust is selected. There is also an annual administration fee of 1 per cent.
The investment managers are also planning to launch a Tessa-only Isa for Tessa maturities from 2000 onwards.
