Equifax and Experian both sell expensive credit checks online which cost £6.99 / £9.99 / £14.99. These are all a rip off and are often by monthly subscription. Spotted this hidden on the Equifax site but by the looks its basically the same thing, just on paper! I dont think they want you to do this though!
By law, you are entitled to a copy of your Statutory Credit Report by post for a fee of £2.
