silly me; there i was i thinking my child care voucher would automatically increase from £217 to £243 after the Budget and I have just got a voucher from Busy Bees for £217. "Oh," they said, "haven't you contacted your HR department and signed a new salary sacrifice agreement saying you want the new amount? We can't do anything til then." In this age of emails, it would have been nice if they had warned their customers that this was necessary, surely.
