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 April 15, 2024, we will discontinue offering certificates from GlobalSign.
However, we can provide a suitable alternative from Sectigo, formerly known as Comodo.
