Fixed means your interest rate won’t change for a set period of time.

The actual mortgage rate you'll be offered depends on the following factors:
- How much you earn

Offset mortgage FAQs
Whether an offset mortgage is a good idea depends on your personal circumstances.
You generally need a large amount of savings that you can afford to leave untouched. The higher the savings, the more you'll save on interest payments. If you withdraw money from your savings, your interest amount will rise.
If you choose to overpay your mortgage (either by increasing your monthly payments or with a lump sum), you may be able to pay it off quicker.
But you should check with your lender before you do this, as there is normally a limit to how much you can overpay before you face early repayment charges (ERCs).
If you choose to overpay on your mortgage, you could benefit from a shorter mortgage term and paying less interest overall. But there are normally limits to how much you can overpay before you face additional charges and you also won't be able to get that money back.
If you would prefer to have your money accessible, you could instead pay more into your savings account to reduce your monthly interest charges. The right decision for you will depend on your individual circumstances.
It depends on your personal circumstances. If you have a bigger deposit, you might benefit from lower interest rates on your mortgage. But once you’ve put down the deposit you won’t be able to get it back.
With an offset mortgage you have savings for the future when you’ve paid off your mortgage. But if you withdraw from your savings before then, your monthly payments could increase.
