Our window supplier/installer has just turned up with "bad news". The lorry is due to be loaded on the 20th from Poland with all our windows and bifolds etc. He is now saying he's been advised that we have to pay the VAT and duty on this upfront and then hopefully reclaim it later.   Surely, as a new build, we are not liable for any VAT on this and the UK already has a trade deal with Poland as part of the EU so there will be no VAT due on this job?   Confused.
