Automatic 3.5t Horseboxes for Sale in the UK

Horseboxes vary widely in weight depending on their size and build. A small 3.5-tonne horsebox (the kind you can drive on a standard car licence) typically weighs around 2,300–2,700kg unladen, leaving the rest as payload. Larger 7.5-tonne horse lorries are usually much heavier, often weighing 5,000–6,000kg empty, with bigger payload capacity and more living space.

A horsebox’s payload is the maximum weight it can legally carry, including horses, tack, people, and equipment. Payload varies by size - a typical 3.5-tonne horsebox often has a payload of 800kg–1,200kg, while larger 7.5-tonne lorries can offer 1,500kg–3,000kg or more, depending on the build and features. Build quality and unladen weight vary between manufacturers - for example, an Equi-Trek may differ in payload from an Oakley or Whittaker of similar gross weight, so always check the individual vehicle's weight plate.

The choice between manual and automatic depends on how and where you drive. A manual gearbox gives you more direct control over gear selection, which some drivers prefer when towing or navigating steep terrain. Automatic gearboxes offer easier, more relaxed driving - especially useful in traffic or on longer journeys - and are increasingly common on newer horsebox builds.

Both options are available across 3.5t and 7.5t horseboxes. Consider your driving experience, typical journey type and personal preference when deciding.

In the UK, you can drive a 3.5-tonne horsebox on a standard car licence (Category B). For anything over 3.5 tonnes - such as a 7.5t horsebox - you’ll need a Category C1 licence, and for even larger lorries you’ll need Category C (HGV). Your licence will show which categories you already hold, and if you passed your test before 1 January 1997, you may automatically have C1 entitlement.
