Understand van size terminology

SWB = Short Wheelbase, MWB = Medium Wheelbase, LWB = Long Wheelbase, XLWB = Extra Long Wheelbase. H1 = Low Roof, H2 = Medium Roof, H3 = High Roof. These combine to describe the van's load space dimensions.
Measure your typical load

Measure the longest, widest and tallest items you regularly carry. Add 10–15% headroom for manoeuvring. This tells you the minimum load space dimensions you need.
Consider where you'll drive and park

LWB high-roof vans are harder to park in multi-storeys and tight city streets. If you work mainly in urban areas, a compact or SWB van may be more practical despite the smaller load space.

Check payload capacity

Payload is the maximum weight you can carry (gross vehicle weight minus the van's kerb weight). A larger van doesn't always mean more payload, some LWB models are heavier, leaving less capacity for cargo.
Match the van to your trade

Plumbers and electricians usually need SWB/MWB low-roof vans with good racking options. Couriers need LWB high-roof for volume. Builders need dropside or tipper options. Removals firms need Luton bodies.

Frequently Asked Questions

For a one-bedroom flat, an LWB high-roof panel van (around 10–12 m³ load volume) usually suffices. For larger homes, a Luton van with tail lift (15–20 m³) is the standard choice in the removals industry.

Yes, as long as the van's gross vehicle weight (GVW) does not exceed 3,500 kg. This covers the vast majority of commercial vans. Anything over 3.5 tonnes requires a Category C1 licence.
