The lenders themselves make it clear they don’t as well, as do the credit reference agencies. They only consult the records.
The only reason its good to check your credit reference is purely to ensure its correct and to stop fraud.
I’ve never seen the point of relying on a score personally, but some think its a godsend.
A good example is Sky mobile, it has a totally different process than Sky itself, so you may be with Sky and declined a Sky mobile signing up to both at the same time, using the same details, using the same score.
