The best place to see your credit score is with the credit agencies. You will have to create an account with them, but it's free.
TransUnion - Please note to see your TransUnion credit score you will need to create an account with their partner, Credit Karma.
While you're there, ask a credit agency to provide a free statutory report. It contains most of the data on you that they provide to lenders. It's worth checking out to see if there are any errors that need fixing.
And remember, checking out what credit agencies hold on you doesn't affect your credit score.
