Hi Gswain,
I have had a client that did just this last week.
You can't do it all in Sterling and you do have to raise a Bankers draft from the UK but yes it is a simple enough process(confuses the notary a little).
You will have to have some euros as the costs and retentions have to be paid in euros.
The client in question had to have approx 15,000€ from a sale price of 200,000€.
Hope that helps
Regards
Georgia
