I currently have an old student credit card with £500 limit with Natwest and they won't increase the credit limit as it is a student card. I graduated over 10 years ago and could do with a higher limit so I can use a CC for extra protection buying holidays (when allowed) and the like.
Not sure if relevant but I'm a higher rate tax payer with a good credit score. Ironically my score on credit karma "could be better" as my credit limit is so low that whenever I purchase something for a couple of hundred pounds it considers I'm using a high proportion of my available credit.
What would be considered a standard credit card limit that I should aim for? I was wondering whether 3k / 5k is considered the norm but unsure.
