I have always found it an injustice that those who look to shop around for a loan, credit card or mortgage actually risk damaging their credit rating in the process. It goes like this – each time a potential lender checks out your credit file it leaves a trace. If the consumer is turned down – for whatever reason – the trace turns into a great big muddy mark and, in these straitened lending times, this can be enough to bar the individual from accessing credit elsewhere.
