Hello together

So, I've been through the procedure....

When leaving Switzerland:
-Passive refinement
-transfer via EU territory with a T1
-deposit of approx. 30% of the vehicle value (EU territory)

Entering England:
-Clearance T1
-Temporary import vehicle
-Deposit again of approx. 30% of the vehicle value (England)

Exit England:
-Export Temporary Imported Vehicle
-transfer across EU territory with a T1
-Deposit of approx. 30% of the vehicle value (deposit can be taken over)

Entry Switzerland:
-Clearance T1
-Active refinement

Was time-consuming and complicated. But legal. Without VAT, the fun cost approx. 950 pounds for all documents.
A big part could be saved by the VAT (about 2/3), and the more you spend, the bigger the saving.
(This was calculated without Swiss VAT)

Many greetings and hopefully I can help someone, as this is the only way to get English VAT back if you have your vehicle optimised or repaired.
