per crema de brancatge agricola or in good old google " For agricultural burning branches" I am owf to get mine in the morning. I just take my old ones along and they hand over a new one. This year a few have been caught out when fires have got the better of them and even worse they had no licence. It only takes half an hour and can save you a lot of trouble if things do get out of hand.They also send you a text if burning is suspended.  8-)
