Outfox dont have a way to directly reduce the payment online.
You can however claim a refund if your credit is more than one months payment.

Already done that twice this year and right now the balance is well over again.
However, since winter is approching, I'll wait and see how much that eats into it.
Its boosted by the Warm House payment, and of course, electricity being 5% cheaper for the next 8 months.
