VAT and prices

Entering a VAT registration number

A VAT registration number is alphanumeric and consists of up to 15 characters. The first two letters indicate the respective EU member state, e.g. GB for the United Kingdom or DE for Germany, and must be included when entering your VAT registration number.

How is VAT calculated?

VAT will be calculated in accordance with the VAT regulations in force at the time. See the HM Revenue & Customs website for more information.

Incorrect VAT information

If, as a result of incorrect information being submitted, a sale that should have been inclusive of VAT is made without VAT being charged, BSI reserves the right to recover a sum from the customer equal to the VAT that should have been charged.
