Most UK small businesses start with a small-to-medium panel van — typically something in the SWB (short wheelbase) “L1” size. It’s big enough for tools, parcels or a couple of bulky items, but still easy to park, cheap(ish) to run, and practical for mixed town and motorway work.
Why L1 vans are the common starting point
An L1 van usually gives a sensible balance of load space, payload and manoeuvrability. For trades, it’ll take toolboxes, ladders (often with a roof rack) and materials without feeling like you’re driving a “big van” every day. For delivery work, it suits multi-drop routes and tight residential streets.
What pushes people up or down in size
Go smaller (car-derived van or compact van) if you mainly carry light items, need city-centre access, or park on driveways. They’re often cheaper to insure and can be more fuel-efficient, but you may run out of space quickly.
Go bigger (L2/L3 medium van or large van) if you carry long materials, bulky stock, or need higher payload. The trade-off is higher purchase price, tyre costs, and generally more hassle in tight parking.
Two checks that matter on a new van order
1) Payload, not just load volume: A van can look huge but have a modest payload once you add racking, ply-lining, a bulkhead, roof bars and a driver. Ask the dealer for the payload on the exact spec.
2) Urban compliance: If you work in London or other Clean Air Zones, consider a new Euro 6 diesel or electric to avoid daily charges (rules vary by city and can change).
If you tell me your trade, typical loads (weight/length), and where you drive, I can suggest the most sensible starting size (and whether SWB or MWB makes more sense).
