I am a resident of Scotland, and have a credit card issued by my bank in my name only. I recently received a letter stating:
Your credit limit is increasing
We have good news for you. We wanted to thank for being a
$BANKNAMEcustomer, and after careful consideration, we've decided to increase your credit limit from
$Yon the 05 August 2018.
This amounts to a ~30% increase!
The letter goes on to say that I can decline this increase or request that it takes effect earlier.
What it fails to say is what effect, if any, this increase will have on my credit rating or ability to obtain credit elsewhere. My credit limit is already higher than I intend to use - due to past unrequested increases! - so I am not concerned by accruing additional debt above my current limit.
Other QAs (eg If I increase my credit limit will my credit score go up? or Is there a "catch" on my "increased credit limit"?) suggest that if I was in the US this shouldn't have a negative effect on my credit rating.
What is the situation in the UK? Would an unrequested increase in credit limit effect a credit rating and/or effect one's ability to obtain credit?
