Buying commercial goods from Portugal - Collecting and bringing them into UK in my own van?

Hi all, I need to import some goods from Portugal and the timescales between when the goods are complete and when I need them to be in UK is so tight that I dont want them to run into any trouble with couriers. Does anybody know what the process is with regards to me colelcting them myself in a van and bringing them back into the UK, probably via Calais. Do I just need to have invoices and sort taxes when back in UK or is it not that simple?

Have a look at the guidelines here. There is a simplified electronic declaration for goods belo £2500 provided they are not restricted goods. https://www.gov.uk/guidance/bringing-commercial-goods-into-great-britainin-your-baggage. You may need to check requirements for export from Portugal / EU . Your supplier is also likely to need proof of export so they don’t charge the Portuguese VAT . Perhaps your supplier can assist you.
