LeaderTelecom B.V. is VAT-registered with the UK’s HM Revenue and Customs (HMRC) and has a UK VAT number (GB373878249) , so we can charge UK VAT as normal. All invoices for UK customers now include 20% VAT, although still denominated in EUR as the company’s tax residency is the Netherlands.

As of March 10, 2025, we will discontinue offering certificates from Entrust due to the divestiture of Entrust’s SSL/TLS business to Sectigo.
However, we can provide a suitable alternative from Sectigo, formerly known as Comodo.
