You should be allowed to deduct the increase in costs from your share of the additional income - so your share being £270, less £370 leaves a minus figure of £100, which is then deducted from the creditors £270 share - leaving £170 to pay.
Whilst this does enable you to keep paying into your IVA, aren't you going to feel that you are going out to work for no personal gain? That said, one day per week is not so bad.
