We are planning to drive over to our place in

We are planning to drive over to our place in northern Tuscany in April with a van load of furniture (all second hand) bits and bobs for the house etc but I have suddenly realised that this may not be as straightforward as it was pre brexit!! What are the rules regarding transporting stuff now? I had also thought it might be possible to take my 50 year old little Fiat (in a van, not driving it!) for use over the summer - I’m guessing that May no longer be possible???
