TransUnion credit score, rating and report

Everything you need to know about your TransUnion credit score and report.

When you apply for credit, such as a mortgage, loan or credit card, lenders will decide whether to approve your application by looking at your credit report and score. Your credit report also determines how much they will offer you and how much interest to charge.

TransUnion (formerly known as Callcredit) is one of three main credit reference agencies in the UK used by lenders when deciding how much of a risk you are as a potential borrower and how much money they can make from you. A number of factors detailed on your credit report make up your credit score, which ultimately places you in a rating group ranging from very poor to excellent.

What is a TransUnion Score?

TransUnion uses everything it knows about you in your credit file and boils it down to a number. If you have a good score, you can usually be approved for a loan, credit card or mortgage and receive decent interest rates.

It’s important to know that although all lenders use your credit score when going through the approval process, they also have their own qualifying criteria as well.

What does a TransUnion credit score look like?

Each credit reference agency has its own scoring system. TransUnion scores range from 0 to 710: the higher your score, the better your chances of obtaining credit.

  • TransUnion: 0-710
  • Equifax: 0-700
  • Experian: 0-999

Depending on your score, you’ll be rated as having excellent, good, fair, poor or very poor credit:

TransUnion credit scoreTransUnion credit ratingWhat this means for you
0-550Very poorIt’s highly likely your credit application will be rejected.
561-565PoorYou have a chance of being approved for credit, but are likely to be charged a high interest rate and have a low limit.
566-603FairYou should be offered reasonable interest rates, but are likely to have a low credit limit.
604-627GoodYou’re likely to be approved for credit, but won’t necessarily have the best interest rates.
628-710ExcellentYou’re very likely to be approved for competitive credit offers.

If you want to find out your credit score, you can do so for free from all of the credit reference agencies. If you want to access your credit report and find out the reasons behind negative marks to your score, you’ll usually have to pay, although some agencies offer a free one-month trial subscription.

How to improve your TransUnion credit score

If you’ve been rejected for a loan, credit card or mortgage application because of a low credit score, there are steps you can take to improve it.

Be aware, it will take time for good financial behaviours (such as those detailed below) to improve your score and rating.

  • Pay your bills on time and try to make as big of a payment as your financial situation allows to clear the debt faster.
  • Close any unused credit accounts (e.g. old credit cards) as these could impact negatively on the lender’s decision-making process.
  • Register on the electoral roll and make sure your current address is on your credit report. Lenders can be wary if you move home frequently.
  • Keep your credit utilisation ratio low by not maxing out your credit limit. So if you have a balance of £500 and a credit limit of £1,000, your credit utilisation ratio is 50%. A low credit utilisation ratio is preferable and shows that you’re not using most of your available credit.
  • If you have no credit history at all, opening a credit builder card may help build your score.
  • Check your credit report for errors. An administrative mistake could result in you wrongly being rejected for credit.
