Frequently asked questions

What would the estimated balance be at the maturity date based on a £1,000 deposit?
  • Gross interest will be added at the maturity date at the rate of 4.35% AER 

  • This means that if you deposited ÂŁ1,000 on the close date the estimated balance at the maturity date would be ÂŁ1,064.95.  

  • If you deposited ÂŁ1,000 on the open date the estimated balance at the maturity date would be ÂŁ1,069.12.  

What is a fixed-term savings account?

A fixed-term savings account is a locked savings account that offers a fixed interest rate until it unlocks (or matures).

Key details of a fixed-term savings account:

Fixed interest rate:

Your interest rate won’t change, so you’ll always know how much interest you’ll earn.

One-time deposit:

To open a Fixed Rate Saver, you’ll need to deposit at least £1,000. You can add more funds during a short window after opening, until the account closes for further deposits.

No early access:

Withdrawals are only allowed after the account reaches its maturity date.

This account is ideal for those who don’t need instant access to their savings and want a secure way to save.

Is the Fixed Rate Saver the right choice for me?

This account is perfect for you if:

  • You have a lump sum (minimum ÂŁ1,000) you won’t need access to during the term.

  • You’re looking for a competitive, fixed interest rate.

  • You want a secure and risk-free savings option with GWCU
What happens when my fixed term ends?

When your fixed-term savings account matures after the term is over, you’ll have full access to withdraw your funds and the accrued interest will be added to your account balance.

You can also reinvest the funds into a new Fixed Rate Saver, if it is available.

Can I access money from the Fixed Rate Saver before maturity?

No, withdrawals from the Fixed Rate Saver are not allowed before the maturity date.

You can find your account’s maturity date on our website, or in the email you received when you opened the account.

Are my savings in the Fixed Rate Saver taxed?

The Fixed Rate Saver operates on a gross interest rate, meaning tax is not deducted.

It’s your responsibility to report and pay any applicable taxes to HMRC.
