Hi Marvel2017
I'm sorry, but I honestly can't tell you, but I suspect it will be a lengthy wait (months) - unless they make a paper-assessment. New claimants have higher priority over claimants reporting a change of circumstance and many of our members are experiencing waits of 6 months or more for reviews. The one good thing is if you are awarded an increased claim, they will backdate it to the date on which you informed them of the change of circumstance.
