If you’re a trade carrying genuinely heavy kit (plaster, tools, fixings, generators, pipe, tiles), the “best” new van is usually the one with the right payload and axle capacity for your typical load, not the biggest body. In practice, that often means a 3.5-tonne (3,500kg GVW) panel van in a medium or large size, specced correctly, because it keeps you on a standard car licence (Category B) while offering strong carrying ability.

Start with payload (and don’t forget the driver)

Payload is GVW minus kerb weight. Kerb weight includes fuel and often the driver; check the exact definition on the van’s plate/spec sheet. Options like racking, ply-lining, towbar, extra seats, auto gearboxes and 4×4 can cut payload more than people expect. If you routinely carry 800–1,200kg, you’ll want a van with a comfortable margin, not one that’s “just enough” on paper.

Choose a layout that suits dense loads

For heavy equipment, a shorter wheelbase with a high payload can be better than a long van: it’s easier to load safely and you’re less tempted to pile weight behind the rear axle. Look for a strong bulkhead, sensible load-floor height, and plenty of lashing points. If you carry long items as well as weight, a long wheelbase helps, but keep an eye on rear-axle limits.

Powertrain: diesel still makes sense for heavy work (often)

For frequent heavy loads and towing, a modern diesel with the right gearbox can be the simplest choice. Electric vans can work well for heavy kit on local runs, but range drops with weight and motorway speed. If you’re considering electric, check real-world range with your payload and charging access. Grants can apply (OZEV’s Plug-in Van Grant is currently up to £2,500 or £5,000 depending on GVW), but schemes and rates can change—verify on Gov.uk.

Two quick follow-ups to ask yourself

Do you tow? If yes, check gross train weight and towing limits, not just payload.
Do you work in Clean Air Zones? Rules vary by city; new electric vans are typically compliant, while diesel compliance depends on the scheme—always check the local authority site.
