I would be tempted to just claim it, and see what happens.

Convert with the exchange rate converted at the ECB published rate for the day from here http://www.ecb.int/stats/exchange/eurofxref/html/index.en.html

you have to convert DKK to euro then euro to GBP but if you do this at independently published rates, I can't see it causing a problem (my self-build reclaim had a whole mix of receipts with no itemised VAT, receipts with some items struck out so I manually recalculated the VAT remaining etc.)

or alternatively, call them - it may be possible to get them to zero rate the invoice - or check with HMRC, as I can see why they WOULDN'T want to pay it, as you have paid vat to the Danish government but get it repaid by the UK govermenent.

However - this implies it's all OK - see "purchases abroad" section

Thanks for the responses.

Joe - that is particularly reassuring to hear

Thanks, looks quite simple to complete.

I am using a main contract which will limit the amount of goods I pay for direct, but there are still a few receipts I will be accumulating.

<blockquote>I know that you can claim back the VAT on a new build, but does anyone have any experience on whether it is possible to claim back the VAT paid in another EU country via the HMRC return?</blockquote>

Yes and I've done it.

You can claim back the VAT actually paid even if this is higher than the UK rate :-)

I stapled the receipt to a sheet of paper containing the figures converted to £ and entered the £ figures on the spreadsheet.
