Can I have more than one ISA?
There is no limit to the number of ISA plans you can have.
However, though you may end up with many ISA plans over
time, you may only contribute, during any single tax year,
to one Maxi ISA or up to three Mini ISAs - one for each
type of ISA component.
Each tax year you may decide to contribute to an ISA product
(either Maxi or Mini) from a different ISA provider to those
you have contributed to before.
In addition to the contributions you make to a standard
ISA plan, you will also be allowed to invest money into
a TESSA-only ISA, however these plans may only receive money
from maturing TESSA plans. The Maximum that can be invested
into a TESSA-only ISA is the £9,000 capital limit or the
original capital you invested into your TESSA if this amount
is lower.
