Your credit score will improve if you demonstrate that you’ve become more credit-worthy. You can do that by minimising credit applications, clearing up defaults and paying bills on time.
Another tip is to get the one free credit report you’re entitled to each year – that way, you’ll be able to identify and fix any errors.
If you want to fix an error, the first thing you should do is speak with the credit reporting body, which make take of the problem or contact credit providers on your behalf.
The next step would be to contact your credit provider. If that doesn’t work, you can refer the matter to the credit provider’s independent dispute resolution scheme, which would be either the Financial Ombudsman Service or the Credit and Investments Ombudsman.
If that doesn’t work, your final options are to contact the Privacy Commissioner and then the Office of the Information Commissioner.
