Variable rates

A variable rate may go up or down during the term of the loan. This means your repayments may vary as the rate changes. Your business will benefit from any interest rate decrease but if rates increase, your repayments may increase.

Rates effective 1st March 2024 except as noted in 'Things you should know'.

Fixed rates

A fixed rate doesn't change during the fixed interest period so your repayments will stay the same during that time which can help with budgeting and planning.

  • At the end of the fixed rate period, your loan will automatically change to a variable rate loan and the interest rate will automatically change to a variable base rate plus any margins current at the time
  • A margin may apply depending on the type of security provided
  • There are no fixed rates available for Business Equity Access Loans & Business Overdraft
