How Do You Get the Best Cash ISAs?

The best cash ISAs that offer the highest rates are based on you being able to make a higher minimum contribution (e.g £500) and your money is locked in for up to 5 or 7 years, with no easy access.

By comparison, some of the lower rate ISAs allow you to make low minimum contributions, such as £100, and the luxury of having easy access. So you can take out your money and put it back in whenever you want, subject to the current £20,000 limit.

What are the Types of Cash ISAs?

There are a few main types of Cash ISA – we’ve outlined these below, to give you a better idea of your options:


This is a cash ISA that allows you to withdraw cash whenever you want, but it could take a few days before you receive the money into your account.


This is a cash ISA where you can access your money at any time, instantaneously.


As the name suggests, with a Notice ISA, you need to provide the bank with notice about any withdrawals (for example a notice of 60 days). Otherwise, you could be penalised with less interest.


With a fixed term agreement, your cash ISA is tied up for a whole term (such as 1, 2 or 5 years) with a specified fixed rate.


This is a kind of cash ISA which requires you to top up cash into the account on a monthly basis to receive the interest rate offered.

What is the Criteria for Applying?

  • UK resident (Wales, Scotland and Ireland also available)
  • 16 or over for a cash ISA
  • 18 or over for a stocks and shares ISA or an innovative finance ISA

Compare Cash ISAs

To compare cash ISAs effectively using a broker service, you need to consider your requirements and find the balance between earning a higher interest rate and being able to access funds when you need them.

Some savers may be looking to maximise their earnings, in which case, a large contribution with no access for 5 years may be a good option.

Others may be looking to make a small contribution but access their funds when they need them, giving them a lower return.

Many consumers like to do a combination, putting some money into a cash ISA, and some money into other saving accounts too, such as innovative finance ISAs. Provided that it is within the £20,000 ISA allowance, you can invest in multiple products and it is still tax-free.
