There are a number of different types of offer that are available when you shop around for the best ISA deal and it is worth explaining the different deals available so you can work out which is the best offer for you. We've listed the different types of ISA offer below with an explanation of each.
- Cashback offers - Paid in a variety of ways. Can usually be paid into your nominated bank account or paid as cash into your investment account.

- Fee-free deals - Offers fee-free investing for a period of time, often up to 12 months.
- Free shares - A popular deal offered by trading apps as an incentive for signing up.
