New 4.5t Horseboxes for Sale in the UK

A 4.5 tonne horsebox and a 4.5 ton horsebox both refer to the same weight class vehicle, but the wording depends on country:

• Tonne (metric tonne) - used in the UK and Europe
  • 1 tonne = 1,000 kg
  • The correct term for horseboxes in the UK is usually 4.5 tonne
• Ton (imperial ton) - used mainly in the USA
  • 1 ton = 907 kg
  • Not generally used in UK vehicle classifications

Because horseboxes in the UK are regulated using metric measurements, a 4.5 tonne horsebox is the accurate term for listings, insurance, road tax, driving licence rules, and DVLA documentation.

The value of a 4.5 tonne horsebox depends on the age of the chassis and conversion, mileage, build quality, payload capacity and overall condition. A 4.5t sits between the popular 3.5t and 7.5t weight classes, offering more space and payload than a 3.5t while remaining lighter and more manoeuvrable than a full 7.5t lorry.

Prices vary depending on specification, so it is important to compare similar listings and verify the vehicle's condition before making an offer.

Payload is the difference between the Maximum Authorised Mass (MAM) of 4,500 kg and the unladen weight of the horsebox. Most 4.5t horseboxes offer a payload between 1,000 and 1,500 kg, though this varies depending on the build specification.

A 4.5t horsebox can comfortably carry one or two horses with tack and equipment. Heavier living accommodation, water tanks and additional storage will reduce the available payload.

Always check the VIN plate for the exact unladen weight, and consider using a public weighbridge to confirm the real figure before you buy.

You need a Category C1 licence to drive a 4.5 tonne horsebox. A standard Category B car licence only covers vehicles up to 3,500 kg, so it is not sufficient for a 4.5t lorry.

If you passed your driving test before 1 January 1997, C1 entitlement (vehicles up to 7,500 kg) is automatically included on your licence. Drivers who passed after that date need to take a separate C1 test, which involves a medical, a theory exam and a practical driving assessment.
