Should I write letter

You say that you have been overpaid, does this mean that you exceeded either the hours worked (on paper) or the income limit for PW?

The legislation covering PW is black and white, if either of the limits are exceeded then your ESA(CB) is not payable for that period, the DWP can take an average where there is an established variation in work hours or pay but it will be at the discretion of a DM whether they apply this rule.

As to whether you should contact them, I can't tell you that you don't need to, these things can get flagged to the DWP by HMRC via your tax but if the amount is small and is a one-off then it might be ignored.
