When you have placed an order for the UK and since Brexit the UK is a non-EU country, customs can charge you VAT.
We still ship to the UK as we used to do after Brexit. As for every non-EU customer, you don't pay VAT to us when shopping with us. However, VAT can be charged by your local customs service. UPS will charge you for the amount owed to the customs service.
