Well do a soft search to check if youre eligible for a Top Up loan. This will not be visible to other lenders on your credit file. If your application is successful and you choose to take the Top Up loan (which combines any existing loan amount and Top Up loan amounts) this will appear on your credit file as a new loan, and your existing loan will show as settled.
What happens to my existing loan?
If your approved for a Top Up loan well combine your new and any existing amount to make one new loan. Well close your existing loan and this will show as settled on your credit file.
