Nucleus ISA
What we offer, how it works, and the benefits for your clients
The Nucleus ISA is our simple, smart individual savings account. This stocks and shares ISA offers flexible access and a wide asset choice, giving your clients a secure savings product with access to tax-free withdrawals on demand.
With the Nucleus ISA, they can:
- subscribe by bank transfer or Direct Debit, up to the annual limit (currently £20,000 per tax year, or £9,000 for a Nucleus Junior ISA)
- use BED & ISA to establish or top-up an individual ISA product from existing holdings
- invest in platform funds and managed portfolios, as well as exchange traded investments (ETIs) through the platform's integrated stockbroking service
- grow ISA savings in a mostly tax-free environment
- make single or regular tax-free withdrawals at any time, with flexible access allowing them to replace any withdrawals within the tax year back up to the annual limit
