These Regulations revoke and replace the Road Vehicles (Payment of Duty by Credit Card) (Prescribed Fee) Regulations 2005 and remove the need to pay a fee where Vehicle Excise Duty (“VED”) is paid using a personal credit card (i.e. non business), or personal credit card account. Otherwise, the fee remains £2.50.
