Ok long and short of it, I was turned down from buying a car today as they failed me on my credit score. The lady said to check on Experian and see whats causing the drama. Well I have a look and even pay the extra Â£5 to see the actual score itself. It then gives me a pros and cons list as to whats affecting it. The only red (bad) thing affecting it apparently is the fact im not on the electoral roll. Lots of plus points and only the above mentioned negative. My rating was classed as "very poor". So my question is, if I jump on the electoral register will that have such a dramatic effect on my score or is the whole site full o'shiite?
