A subscription refers to the amount of money you contribute to your Cash ISA during a tax year (6 April to 5 April). It does not refer to a fee — it’s simply the total of your deposits into the ISA.
For the 2025/26 tax year:
- You can subscribe up to £20,000 across all ISA types (Cash, Stocks & Shares, Lifetime, and Innovative Finance ISAs)
- Glasgow Credit Union’s Cash ISA allows you to use all or part of this allowance subject to your aggregate savings balance remaining below £85,000.
Rules for Subscribing to a GCU Cash ISA
To subscribe to a Glasgow Credit Union Cash ISA:
- You must be a UK resident aged 16 or over
- You must be a member of Glasgow Credit Union and have opened a Glasgow Credit Union Cash ISA product
- You can only subscribe to one Cash ISA per tax year
- Subscriptions must be made in cash only (no transfers from shares or investments)
If you’ve already subscribed to a Cash ISA from another provider this tax year, you must transfer the full balance to GCU before making a subscription to your Glasgow Credit Union Cash ISA.
How to Subscribe
You can fund your Glasgow Credit Union Cash ISA by:
- Setting up a Direct Debit or Salary Deduction

- If you’re not sure how much of your ISA allowance you've already used elsewhere, we recommend checking with your previous provider or HMRC.
Can I Transfer an Existing ISA to Glasgow Credit Union?
Yes! We accept ISA transfers, which allow you to move funds from a previous year’s ISA from another provider without affecting your current year’s allowance. If you already have a Glasgow Credit Union Cash ISA you can begin this process by completing the ISA Transfer Form .
