What is TransUnion UK?
TransUnion is one of the three main credit reference agencies (CRAs) operating in the UK, alongside Experian and Equifax. It holds credit records on millions of UK consumers and businesses, including information on credit accounts, payment history, electoral roll data, and public records such as CCJs. Lenders, landlords, and employers use TransUnion credit reports to assess creditworthiness. TransUnion UK is registered with the ICO under UK GDPR.
Which UK banks and lenders use TransUnion?
TransUnion is used by a wide range of UK lenders including HSBC, NatWest, Nationwide, Capital One, and many specialist lenders and fintechs. Not all lenders use all three CRAs — some prefer Experian, some Equifax, and some use a combination. If a lender uses TransUnion, a credit search will appear on your TransUnion report. Lenders using open banking affordability checks may use TransUnion credit data alongside real-time bank transaction data.
How does TransUnion relate to open banking?
TransUnion credit data and open banking data are complementary rather than identical. Open banking provides real-time transaction data — income, spending, and account behaviour — while TransUnion provides historical credit records. Some UK lenders now use both: a TransUnion credit check for the credit history, and an open banking AISP connection for real-time affordability. TransUnion itself has invested in open banking data capabilities through its own product suite.
