Frequently asked questions

Which repayment frequency is best?

Match your income cycle. More frequent payments can reduce total interest marginally.

What happens when IO reverts to P&I?

Repayments increase because you begin repaying principal alongside interest.

Do fees affect comparison rate?

Yes. Comparison rates include certain fees to reflect effective annual cost beyond the headline rate.

How do extra repayments help?

They reduce principal faster, lowering interest and shortening the loan term.
