I want my old credit limit back, is that possible?

Sorry, this is not possible.

All credit limits going forward will be calculated using the new solution. When implementing the new scorecard, a new Credit Limit strategy was developed alongside customer feedback to ensure that the credit limits being used were a better reflection of the UK marketplace, the new limit strategy is weighted based on the current risk score of the business and proven financial factors such as, Working Capital, Equity, Assets Values etc.
