Looking to reinvest your Fixed Rate Cash ISA?
If you want to retain the benefits of having a fixed rate of interest, consider reinvesting by opening a new Fixed Rate Cash ISA. You can transfer some or all of your balance into a new ISA (including previous years' subscriptions) and subscribe up to an additional £20,000 in the current tax year.

How do I open and manage my account?
Eligibility:
- Aged 18 years or over
- You must provide your National Insurance number if eligible to hold one.
- To subscribe you must be resident in the UK for tax purposes, or if not a resident, be a UK Crown servant serving outside the UK, or be married to, or in a civil partnership with, such a person
- Hold an HSBC current account
- This account can only be opened in a sole name
How to open the account
Open an account via the HSBC UK Mobile Banking app, online banking, by phone or in branch.
You'll need to give us a call if you’re a UK Crown servant serving overseas, or married to or in a civil partnership with one, and your permanent residential address is outside the UK.
Minimum / maximum balance
A minimum of £500 must be deposited into the account.
This can be made up of one or more of the following:
- Current tax year subscriptions
- Transfer of current and / or previous tax years’ subscriptions from another cash or stocks and shares ISA
We must receive the minimum amount of £500 or the transfer instruction within the first 30 days.
If you're choosing to transfer in, we must also receive the funds from your previous ISA provider within the first 70 days.
The overall annual ISA subscription limit is subject to change every year (currently £20,000). Within this, the Lifetime ISA has its own annual payment limit (currently £4,000).
There's no maximum limit for previous years transfer-in balances.
You can only subscribe to one type of cash ISA and one type of stocks and shares ISA in the same tax year across HSBC and first direct.
How to manage the account
Once opened you can view your balance by using online banking and the HSBC UK Mobile Banking App (device restrictions apply), where you can chat to us 24 / 7 (subject to maintenance periods). You can manage the account using telephone banking or in a branch.
Can I withdraw money?
Any withdrawals must be in full and will result in the account being closed.
You may be subject to an early closure fee if you close your account after the 30-day cancellation period.
The early closure fee will be the lower of the interest earned on your account, up to a maximum of the interest earned in the first 90 days’ that the account is open. This means that if you close your Fixed Rate Cash ISA before day 90 you could end up with no interest paid.
Your early closure fee will be taken from the balance of your Fixed Rate Cash ISA. If you withdraw funds from your ISA you'll lose the future tax benefits associated with holding that money in an ISA.
At the end of the fixed term, we’ll convert your Fixed Rate Cash ISA into a Loyalty Cash ISA. Once the conversion process is complete you'll then be able to access your money without incurring an early closure fee. Partial withdrawals are allowed once it's been converted to a Loyalty Cash ISA.
Additional information
A 30-day cancellation period applies to this account.
You can check if you're eligible for a National Insurance number and apply for one online at GOV.UK - use their search tool and look under national insurance.
If you'd like to transfer an existing Cash or Stocks and Shares ISA to your new Fixed Rate Cash ISA, you need to tell us as part of your application.
The value of tax benefits provided by a cash ISA depend on your personal circumstances and tax rules may change in the future.
Subscribing to a HSBC or first direct cash ISA may affect your eligibility to subscribe to a HSBC Help to Buy ISA.
Definitions:
- AER stands for Annual Equivalent Rate. This shows you what the rate would be if interest were paid and compounded each year
- Tax free means free from personal liability to any UK Income Tax and Capital Gains Tax
- ISA stands for Individual Savings Account
- The cancellation period refers to the timeframe you have to close this account without incurring a fee. If you were to cancel, it would be as if you hadn’t subscribed to the Fixed Rate Cash ISA in the first place

If you have a permanent UK residential address you can apply online to either subscribe and / or transfer into a new Fixed Rate Cash ISA.

Transferring in an existing ISA
It's important to transfer ISAs correctly in order to protect your tax-free allowance.
You may be able to transfer an existing cash ISA or an existing stocks and shares ISA into a new Fixed Rate Cash ISA. In either case, you'll need to open the new ISA first, before transferring into it.
Before you do any ISA transfer, make sure you check the terms and conditions of the ISA you’re transferring from, in case there are any withdrawal restrictions or charges.
