Any credit product you apply for or are approved for will have an effect on your credit score. While some of the possible effects can’t be avoided, others will depend on how you manage your account.
In our guide, thimbl explains the different ways that a balance transfer credit card could change your credit score.
Do balance transfers hurt your credit score?
A balance transfer credit card could affect your credit score. Whether the effect is positive or negative will largely be down to how you manage your account.
Below, we’ve listed some of the ways that your credit score could be affected by a balance transfer credit card.
- The application process
When you make an application for a credit product, the provider will carry out a creditworthiness assessment, which will involve a hard search and/or an Open Banking check. A hard search will be visible on your credit file for up to 12 months, and undergoing multiple hard searches within a short period of time could damage your credit score. With this in mind, you should try to keep your credit applications to a minimum.
You can check your eligibility for the thimbl Balance Transfer Credit Card with no impact to your credit score.* - Repayments
You’ll need to make at least the minimum repayment amount due on your account balance each month. If you make a late payment, you could be charged a fee by your provider, and your credit score could decline. In addition to this, if you have a promotional offer on your account, such as a period of low or no interest, you could lose access to the offer.
If you’re struggling to make the repayments on your credit card, please contact your provider. They will be able to discuss any options that may be available to you to help reduce some of the financial pressure you’re facing.
Worried about money? We’ve included some resources at the bottom of the page. - Your old credit card(s)
What happens to an old credit card once you’ve transferred the balance?
In this situation, you have two options: either contact the provider of your old credit card and ask them to close the account or keep it open.
There are potential pros and cons to both options, and it’s really up to you to decide what you do with your old account(s). - A credit account contributes to your overall credit utilisation; that’s the total amount of money available to you across all forms of borrowing. The lower your total credit utilisation, the better the impact on your credit score.
- You may be charged an annual fee.
- Fraud risk. If you keep your account open but don’t keep a close eye on it, you may not notice any fraudulent activity.
- With another line of credit available to you, you could be tempted to spend money that you don’t need or can’t afford to repay.
- Could reduce the temptation to spend money.
- Fewer accounts to manage.
- You could avoid any annual fees associated with the account.
- Your available credit amount will decrease, which will affect your overall credit utilisation amount.
- Your credit limit
It’s also important to ensure that you stay well within your credit limit. If you try to spend over your credit limit, your transaction could be declined. - How you use your credit card
You should try to avoid using your credit card to withdraw money from a cash machine. This is known as a cash advance and could be viewed as poor money management, which in turn could lower your credit score.
| Option | Potential Pros | Potential Cons |
|---|---|---|
| Keep your old credit account open |
|
|
| Close your old credit account down |

Does transferring a balance look bad on your credit report?
Transferring a balance in itself won’t look bad on your credit report, but as we talked about in the section above, there are many factors that could impact your score.
For example, making multiple credit applications in a short space of time will leave a mark on your credit file and could be viewed negatively by potential lenders.
The thimbl Balance Transfer Credit Card
The thimbl Balance Transfer Credit Card comes with a personalised starting credit limit between £500 and £2,000, with 0% interest on balance transfers for six months from the date your account is opened.
It’s important to note that once the 0% interest-free period ends, any balance remaining will be charged interest at the standard rate.
Representative example: Assumed borrowing of £1,200 for 1 year, at a purchase rate of 39.9% (variable), Representative 39.9% APR (variable). 3% balance transfer fee (or £3, whichever is higher.
You can transfer up to 97% of your available credit limit, and you will be charged £3 or 3% of the balance, whichever is higher. We’ve included some examples below. Please note that these examples are for illustrative purposes only.
| Balance transfer amount | Fee | Explanation |
|---|---|---|
| £500 | £15 | 3% of £500 is £15, which is higher than £3. |
| £50 | £3 | 3% of £50 is £1.50, which means the minimum transfer fee of £3 would be charged instead. |

What will my credit limit be?
You will always be made aware of any credit limit changes to any credit cards you have beforehand, and you do not have to accept a credit limit increase if you don't feel it's right for you.
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.
You should try to make your missed payments as soon as possible.
