If you mean cookie banners then no, they won't stop. UK data protections laws are going to be almost entirely unchanged come 1st Jan. Having said that this doesn't mean there will be no practical effects, as our status with regards to other EEA countries is changing so data transfer between EEA and the UK is affected. It also seems likely that UK data protection laws will start to diverge from EU data protection laws over time, though what this might look like in practice is anyones guess.
