If you want your credit limit to be increased or decreased, you can simply log on to your Online Account Manager or call NewDay’s customer services on 03308380170. They always keep an eye on your account to see how you’re getting on – they need to see that your account is well-managed, and that you’re making payments on time over a number of months before they can offer an increase. It’s best to keep your account up to date, as this will improve your chances of getting an increase accepted. To do this, make sure you stay within your credit limit and pay at least the contractual minimum payment each month..
