Vehicles (Excise) Act 1971

18 Alteration of vehicle or of its use

(1) Subject to the provisions of this section, where a vehicle licence has been taken out for a vehicle at any rate under this Act and the vehicle is at any time while the licence is in force used in an altered condition or in a manner or for a purpose which brings it within, or which if it was used solely in that condition or in that manner or for that purpose would bring it within, a description of vehicle to which a higher rate of duty is applicable under this Act, duty at that higher rate shall become chargeable in respect of the licence for the vehicle.

(2) Where duty at a higher rate becomes chargeable under subsection (1) above in respect of any vehicle licence, the licence may be exchanged for a new vehicle licence, for the period beginning with the date on which the higher rate of duty becomes chargeable and expiring at the end of the period for which the original vehicle licence was issued, on payment of the appropriate proportion of the difference between—

(a) the amount payable under this Act on the original vehicle licence; and

(b) the amount payable under this Act on a vehicle licence taken out for the period for which the original licence was issued but at the higher rate of duty, that amount being calculated, if that rate has been changed since the issue of the original licence, as if that rate had been in force at all material times at the level at which it is in force when it becomes chargeable.

(3) For the purposes of subsection (2) above the appropriate proportion is the proportion which the number of days in the period beginning when the higher rate of duty becomes chargeable and ending with the end of the period for which the original licence was issued bears to the number of days in the whole of the last-mentioned period, that period being treated as 365 days in the case of a licence for twelve months and 120 days in the case of a licence for four months.

(4) Where a vehicle licence has been taken out for a vehicle, and by reason of the vehicle being used as mentioned in subsection (1) above, a higher rate of duty becomes chargeable and duty at the higher rate was not paid before the vehicle was so used, the person so using the vehicle shall be liable to the greater of the following penalties, namely—

(a) an excise penalty of £50; or

(b) an excise penalty of an amount equal to five times the difference between the duty actually paid on the licence and the amount of the duty at that higher rate.

(5) Where a vehicle licence has been taken out for a vehicle of a certain description, duty at a higher rate applicable to vehicles of some other description shall not become chargeable in respect of the vehicle by reason of the vehicle being used as mentioned in subsection (1) above, unless the vehicle as used while the said licence is in force satisfies all the conditions which must be satisfied in order to bring the vehicle for the purposes of the charge of duty under this Act into the said other description of vehicles

(6) Where duty has been paid in respect of a vehicle at a rate applicable under Schedule 4 to this Act, then, so long as the vehicle is to a substantial extent being used for the conveyance of goods or burden belonging to a particular person (whether the person keeping the vehicle or not), duty at a higher rate shall not become chargeable in respect of the vehicle by reason only that it is used for the conveyance without charge in the course of their employment of employees of the person aforesaid.

(7) Where duty has been paid in respect of a vehicle at a rate applicable to farmers' goods vehicles under Schedule 4 to this Act, duty at a higher rate shall not become chargeable in respect of the vehicle by reason only that, on an occasion when the vehicle is being used by the person in whose name it is registered under this Act for the purpose of the conveyance of the produce of, or of articles required for the purposes of, the agricultural land which he occupies, it is also used for the conveyance for some other person engaged in agriculture of the produce of, or of articles required for the purposes of, the agricultural land occupied by that other person, if it is shown—

(a) that the vehicle is so used only occasionally;

(b) that the goods conveyed for that other person represent only a small proportion of the total amount of goods which the vehicle is conveying on that occasion; and

(c) that no payment or reward of any kind is, or is agreed to be, made or given for the conveyance of the goods of that other person.

(8) Where duty has been paid in respect of a vehicle at a rate applicable to farmers' goods vehicles under Schedule 4 to this Act, duty at a higher rate shall not become chargeable in respect of the vehicle by reason only that, during such periods and in such areas as may be specified by order of the Treasury made by statutory instrument, it is used, whether or not by the person in whose name it is registered under this Act, for any such purpose as is specified in the order.

An order under this subsection may be revoked or varied by a subsequent order of the Treasury.

(9) Subsection (8) above shall continue in force until such date as Her Majesty may by Order in Council determine.
