Being excluded from MARP is not the end of the World. Also it is not permanent. I have had a number of client who have been excluded from MARP for non-co-operation but then subsequently re-input when required info etc arrives. I wouldn't tend to panic about any inference that MARP exclusion would mean that you will be singled out for more severe treatment. Write to the bank and find out what specific issues of non-cooperation caused you to be excluded. If you are in a position to provide that co-operation now then do so and request that you be re-input to MARP. This will not happen immediately but will postpone any consequences of MARP exclusion (most occasions there will be no consequences unless you totally stop paying or are really messing them about).
