Value added Tax (VAT) at the current rate is added to all UK-Cheapest invoices. This applies to both EU countries and non-EU countries.
This is a ruling by HM Customs and Excise because the service is supplied in the UK and not the country of the ISP or registrant.
You may be able to reclaim VAT in your own country. Please see the HM Customs & Excise website for details.
