Action by The chancellor has been threatened against mortgage lenders who set arrangement charges far too high. With arrangement fees having risen by two thirds in just 18 months, Alistair Darling has held talks with the Financial Services' Authority (FSA) and the Council of Mortgage Lenders (CML) over what constitutes a fair level for these charges to be set at. He stated afterwards that while these costs obviously have to be met, it is important that borrowers coming off fixed-rates are treated fairly and warned that he would have the FSA investigate if he felt that this was not the case.
