Just a heads up. I've just had a look at my credit report and it is covered in "ROYAL & SUN ALLIANCE INSURANCE PLC" credit checks (30 in total). Turns out every time I used confused.com to get a quote, I got a credit check from them each time. For those who don't know what that means, banks, credit card companies,phone companies, insurance companies or anyone associated with money might have alarm bells ringing when they see so many credit checks carried out in a short space of time (as they may think I having been going mad applying for lots of credit) and thus refuse to approve me for a credit card / bank account / good interest rate etc etc.
So just bare that in mind if you use confused.com and tinker bits to see if something makes a difference to your insurance or to see how much insurance is on a new car you're thinking of buying.
