What is a cash ISA?
1 and 2 year Fixed Rate ISA rates
No withdrawals or deposits during the term. Available for new customers until 11 December 2025.
Available to existing customers until 16 December 2025.
Please note that these issues may be withdrawn early due to limited availability.
Interest is calculated daily and paid annually to your ISA on the first business day in April and on the Maturity Payment Date. Early closure fees may apply.

Specific account eligibility apply.
Your eligible deposits held by a UK establishment of NatWest are protected up to a total of £120,000 by the Financial Services Compensation Scheme, the UK's deposit guarantee scheme. Any deposits you hold above the limit are unlikely to be covered.

Investments through NatWest Invest may also be covered by the Financial Services Compensation Scheme in some scenarios. You can find out more here.
