Probably worth noting the following:
There are 3 credit reference agencies in the UK in order of UK size:
1. Experian
2. Callcredit
3. Equifax
All 3 have 99%+ coverage of finance agreements on their database's.
There are 3 key business information / credit score providers:
1. Dunn and Bradstreet
2. Experian
3. Graydons
If you apply for finance as a consumer they will check you as a consumer. If you apply as a business they check as a business and for sole traders sometimes as a consumer too.
Scoring means a lot but each CRA calibrates differently so one score with one CRA could mean something else with another.
For info - MBFS use Equifax for consumer credit checking.
If you have concerns or want to check your credit rating FOR FREE register at

My industry so I know it well!
