Review of Post Office Fixed Rate ISA

The Post Office offer a range of savings options with a competitive rate of interest. Please see the tables above for latest interest rates and comparison.

History

The Post office are the UK’s largest retail network and the largest financial services chain in the UK with more branches than all of the UK’s banks and building societies combined. They also have a growing amount of direct channels such as contact centres and online meaning they offer great customer service.

The Post Office Fixed Rate Cash ISA:

Features:

  1. A competitive fixed interest rate
  2. You must have a minimum of £500 to invest
  3. No access to your savings until the end of the agreed fixed term
  4. One year fixed term

Interest is calculated daily and paid annually on the anniversary of the account opening. After the end of the fixed rate term, interest is paid annually in March.

In order to open an account, you can:

Open with a single deposit from £500 to £20,000. You can’t make any additional deposits so you may lose the rest of your tax allowance if you don’t invest the whole amount.

You can also transfer an ISA from another provider, there is no upper limit to the value of ISAs you can transfer but it must be at least £500.

The Post Office offer a range of variable interest rate ISAs, bonds and savings account. Check our tables for more info about other options.

Why use a Fixed Rate ISA?

Typically, a fixed-rate Isa account will pay more interest. In exchange for a higher rate, banks will ask you to tie up your cash. Generally, the longer you give up access, the higher the return. As it is a guaranteed amount, you know what you will end up with at the end which makes it a lot safer than investing.

ISAs are a good idea whatever your savings goal. With certain types of cash ISAs, you have instant access to your money, which makes it a flexible way to plan your finances.

It’s also important to remember that ISA allowance limits apply to everyone on an individual basis, so if you’re married or in a relationship, you can both hold your own ISA, each with the full allowance. Meaning you can save over £30,000.

Frequently Asked Questions

Am I committed to one ISA provider forever?

No. You can switch providers with an ISA transfer if you wish. You can also contribute to other ISA providers in separate tax years.

Can I have a Joint ISA?

No, ISA stands for Individual Savings Account and must be solely owned for tax purposes.

Are ISA accounts safe?

ISA accounts are authorised and regulated by the Financial Conduct Authority (FCA). This means that all ISA providers are covered by the Financial Services Compensation Scheme (FSCS) for up to £85,000 if they go out of business.

Please note that this may not apply to the underlying holdings within a Stocks and Shares ISA, and will not cover standard investment losses. 

Can I transfer my Cash ISA into a Stocks and Shares ISA?

Yes, you can transfer from your Cash ISA to a Stocks and Shares ISA at any time. However, do check you won’t lose out by transferring, as some Fixed Rate Cash ISAs may charge a fee or void your interest if you surrender your policy before the fixed term has ended
