Reclaim of VAT on lorry diesel in EU

I cannot seem to get my head round how to make a reclaim for lorry diesel purchased in France mostly, sometimes Germany, Spain, etc.

Purchases are mostly on Shell Card so the information is readily available.  Do we also need to send the little slips issued at the pump as well as the .pdf invoices supplied by Shell online.

Some fuel expenses are made by Barclaycard - again, is the statement enough or are the tiny slips required too? 

 Very occasionally payment is made in euros in cash, again a tiny receipt slip is held for the purchase

Will take ages to scan all those in..

Do we make the claim online on Form VAT65A ?

Is VAT on fuel reclaimable anyway?  For information, the company is a Removals company for private individuals - either moving to EU or back from EU and as the customers are private individuals we charge a UK invoice with VAT at standard rate, as the total for the year is under the French de minimus limit (e100,000).

Just trying to put the claim in for period 1st January 2011 to 31st December 2011 and am aware that the 30th September deadline is rapidly approaching..

Thanks
