Quick answer: What happens if you go over your credit card limit? Most of the time, a payment that would take you over your credit limit is simply declined. If it does go through, some UK providers charge an over-limit fee. NatWest, for example, charges £12 if you go more than £12 over your agreed limit in a statement period, but many providers don’t charge one at all. Going over your limit can also affect how lenders see you, so it’s worth getting back under it quickly.
This guide explains what usually happens in the UK, how people end up over their limit without meaning to, and what to do if it has already happened. There is a short section for US readers at the end.
What happens if you go over your credit card limit?
There are three possible outcomes:
- The payment is declined. This is the most common result.
- The payment goes through and you’re charged a fee. Some UK providers still charge one. Check the fees and charges section of your card’s terms.
- The payment goes through with no fee, but you stay over your limit until you pay the balance down.
Whichever happens, you’ll usually want to bring your balance back under the limit quickly.
How much is an over-limit fee in the UK?
It depends on your provider. NatWest says it applies an over-limit fee of £12 when you go more than £12 over your agreed limit in any one statement period, and the fee appears on your next statement. That means going over by a small amount doesn’t always trigger a fee with that provider. Other providers have their own rules, and many simply decline the payment instead. Your card agreement, or your provider’s help pages, will tell you which applies to you.
How people go over their limit without realising
- Interest is added. NatWest points out that regular interest on your outstanding balance can push you over your limit, even if you haven’t spent anything new.
- Cash advances. These count towards your balance too, and NatWest lists them as another way to go over.
- Payments still pending. Hotels, car hire firms and petrol stations often reserve more than the final amount while a payment is pending.
- Recurring payments and subscriptions that leave your card automatically.
- Foreign spending, where fees and exchange rates change the final amount.

How going over your limit can affect your credit score
Experian says to stay within your agreed credit limits and keep your balances as low as you can. It also says that being close to your limit, for example maxing out a card, can make lenders think you are over-reliant on credit or in financial difficulty. Going over your limit is therefore worth avoiding.
A common rule of thumb is to keep your balance below about 30% of your limit. It’s a guideline, not an official threshold, and lower is generally better. Missed or late payments linked to a high balance can do more lasting harm than the balance itself.

What to do if you’ve gone over your credit limit
- Pay your balance back under the limit as soon as you can. Don’t wait for the due date.
- Check your statement for fees. If you were charged for a first mistake, it’s reasonable to ask your provider to waive it.
- Check your card’s terms, including any promotional rate you have, so you know whether going over your limit has consequences for your card.
- Turn on balance alerts in your card app, set a little below your limit.
- Think carefully before asking for a higher limit. A higher limit lowers how much of your credit you’re using, but it isn’t extra money, and it can make overspending easier.

Frequently asked questions
Can you go over your credit card limit?
Sometimes. Many providers decline payments that would take you over your limit, but some let them through, and interest or cash advances can also push you over it.
How much is an over-limit fee in the UK?
It varies by provider, and many don’t charge one. At NatWest it’s £12, applied when you go more than £12 over your limit in a statement period.
What happens if you go over your credit limit by £1?
It depends on your provider. At NatWest, the over-limit fee only applies if you go more than £12 over, so £1 over would not trigger it. Other providers may decline the payment or have different rules, so check your card’s terms.
Does going over your credit limit affect your credit score?
Experian says staying within your limits and keeping balances low looks better to lenders, and that being close to your limit can suggest you rely heavily on credit. Missed payments can cause longer-lasting damage.
Should I ask my provider to waive an over-limit fee?
If it was a one-off mistake, asking is reasonable. Providers decide case by case.
For US readers: a short note
In the US, rules are different. A card issuer can’t charge an over-the-limit fee unless you have opted in to let transactions go over your limit, and the issuer must confirm your opt-in. You can change your choice at any time. If you haven’t opted in, an over-limit purchase is usually just declined. The CFPB explains what to do if you were charged an over-limit fee, and the rule is set out in Regulation Z section 1026.56.
The bottom line
Going over your credit card limit usually just means a declined payment, and many UK providers don’t charge a fee. Where a fee does apply, such as NatWest’s £12, it’s small. The bigger risk is how a maxed-out or over-limit card can look to lenders, so pay the balance down quickly, set a balance alert, and treat regular over-limit spending as a sign to look at the debt itself.
