You should let the OR know about the extra money. If it is a one-off payment then it will be counted as a windfall and the OR may or may not bother with it. Some OR's may not bother as they will have to complete additional paperwork and, as it is a small amount, may not bother.
If it is a regular amount (i.e. £200 each month) then you should definitely inform the OR and you will probably have to submit and new I&E and may get an IPA based on this amount.
