Your credit history in the UK is recorded by the three Credit Reference Agencies (CRA) Experian, Equifax, and TransUnion (formerly Call Credit).
Ways of getting your credit history:
Via Credibble.com – your data from Equifax, plus gives detailed insights into file problems and what you need to do to fix them on an ongoing basis.
Via Checkmyfile – gets your data from all three Credit Reference Agencies but does not give any insights. So, you will need to read this page in detail to get ideas as to what you’ll need to do to your file.
Individually With Each Agency – you can go to the three Credit Reference Agencies individually, but this would be more expensive.
