Do credit cards with guaranteed approval really exist?
Is it possible to get a very bad credit credit card with guaranteed approval?
If not, are there any alternatives? Can you get a credit card with bad credit?
thimbl investigates some questions that you may have about guaranteed approval credit cards and explains why you should be very wary of any provider claiming to offer this type of product.
Guaranteed approval credit cards UK: What is a guaranteed approval credit card?
In theory, a guaranteed approval credit card would be a credit card that offers guaranteed acceptance; however, it’s vital to be aware that this type of credit card does not exist.
Guaranteed approval credit cards suggest that applicants will be approved regardless of the result of a creditworthiness assessment, or even without having to undergo a creditworthiness assessment at all.
In-line with Financial Conduct Authority (FCA) requirements, all authorised and regulated credit providers must carry out a creditworthiness assessment on everyone who applies for credit. A creditworthiness assessment gives your lender insight into your financial history, as well as the understanding that credit is affordable for you.
While these checks may seem daunting, especially if you have a history of bad credit, it’s important to note that these checks are in place to protect you.
Where can I apply for a guaranteed credit card?
It’s not possible to apply for a guaranteed credit card, because, as discussed, this type of product does not exist.
Any provider that claims to offer guaranteed approval credit cards should be avoided, as they are highly unlikely to be working within the guidelines set by the FCA.
Guaranteed approval credit cards for bad credit UK
If you have a history of bad credit, it’s understandable that you may have searched the terms ‘guaranteed credit cards for bad credit’ or ‘guaranteed credit cards’.
Remember, you cannot get a guaranteed credit card in the UK, regardless of your credit score.
However, this doesn’t necessarily mean that you can’t be considered for a credit card, even if your credit score is looking worse for wear.
Some credit cards, such as the thimbl Credit Builder Credit Card, have been specifically designed for people with bad credit.

What will my credit limit be?

What happens if I fail to make my repayments?
Missed payments will be reported to the credit bureaus, and your account will appear as in arrears. You will be charged a late fee, which is usually around £12. Your credit rating is also likely to decline as a result.
