Direct answer
Work from your inventory, not a vehicle name. A short-wheelbase (SWB) panel van typically offers around 5 to 8 cubic metres of load volume with a payload commonly between 800 and 1,200 kg - enough for a small flat or a handful of large items. A long-wheelbase (LWB) panel van steps up to roughly 8 to 12 cubic metres and 1,100 to 1,500 kg payload, suiting a one or two-bedroom flat's worth of furniture. A Luton van, with its separate box body built over the cab, offers the most volume - commonly 15 to 20 cubic metres - but its payload, typically 900 to 1,200 kg for a standard 3.5-tonne model, isn't always higher than an LWB's, since the box body itself takes up part of the weight allowance. Figures vary by manufacturer and model, and real-world loads involving sofas, wardrobes or mattresses often fill the usable space well before the cubic-metre figure is reached, which is why an inventory-based estimate beats picking a van by name alone.

What SWB, LWB and Luton actually mean
Body shape and construction, not a single fixed capacity number.
SWB and LWB stand for short wheelbase and long wheelbase - they describe the length of the van's chassis and, by extension, its panel-van body, which keeps the familiar sloped roofline running back from the cab. An LWB version of a given van model is simply a stretched body on a longer chassis, carrying more load length and usually a higher payload than the SWB version of the same range, but still within one continuous load area behind the cab.
A Luton is a different kind of body altogether. Rather than extending the existing panel-van shape, it's a separate box built on a cab-chassis, with the box extending forward over the cab roof - the distinctive overhang that gives a Luton its shape and its name (after Luton, where this body style was first produced for furniture removals). Because the box is taller and roughly rectangular rather than following a sloped roofline, a Luton typically carries significantly more volume than an LWB panel van of similar overall length, which is why it's the default choice for full house and flat clearances rather than a stretched panel van.
None of these names guarantee an exact capacity. Manufacturers and converters build SWB, LWB and Luton versions of several different base vehicles, and roof height (standard vs high roof, for Luton box height) changes the figure further. Treat the names as a useful shorthand for roughly what class of job a vehicle suits, and check the specific load volume and payload for the exact vehicle before assuming a figure.
Internal dimensions, load volume and payload compared
The two numbers that actually decide what fits: volume and weight.
A short-wheelbase panel van's load area commonly measures somewhere around 2.4m long, 1.7m wide and 1.4m high internally, giving a load volume typically in the 5 to 8 cubic metre range (roughly 6.5 to 10.5 cubic yards). Payload - the maximum weight of goods it can legally carry, separate from volume - commonly falls between about 800 kg and 1,200 kg, though specific models vary either side of that. An SWB suits a studio or compact one-bedroom flat's worth of boxes and light-to-medium furniture, or a run of a few large single items.
A long-wheelbase panel van extends the load length to somewhere around 3.2m to 3.5m, with similar width and height to an SWB but more usable floor length, giving a load volume commonly in the 8 to 12 cubic metre range (roughly 10.5 to 15.7 cubic yards). Payload typically runs higher too, commonly 1,100 kg to 1,500 kg depending on the model. An LWB is a realistic fit for a one or two-bedroom flat, or a house move where most items are boxed and stackable rather than bulky.
A Luton van's box body is built separately from the cab, and internal dimensions commonly run to roughly 3.5m to 4.2m long, 2.0m to 2.1m wide and 2.0m to 2.2m high, giving a total load volume commonly cited in the 15 to 20 cubic metre range (roughly 19.5 to 26 cubic yards) depending on the specific model and roof height. Payload for a standard 3.5-tonne Luton typically sits around 900 kg to 1,200 kg - broadly similar to, and sometimes lower than, an LWB panel van, because the box body itself is heavier and eats into the vehicle's overall 3.5-tonne weight limit before any load goes in. Fitting a tail lift, which is common on Luton vans used for clearance and removal work, typically reduces available payload by around 250 kg further. This is the main reason a Luton isn't automatically "better" on every measure than an LWB - it wins decisively on volume, but not necessarily on how much weight it can carry.
Access: tail lifts, low loading and awkward routes
Getting items into the van matters as much as the space once they're in it.
Luton vans are commonly specified with a tail lift - a hydraulic platform at the rear that raises heavy or bulky items to loading height rather than requiring them to be carried up a ramp or lifted directly into the box. This matters most for heavy single items such as wardrobes, sofas or appliances, where lifting height and loading-floor height (often higher off the ground on a Luton than on a panel van) would otherwise make loading considerably harder. As noted above, a tail lift reduces the van's available payload by around 250 kg, which carriers factor into their weight planning rather than it being a free addition.
SWB and LWB panel vans generally load at a lower floor height with no tail lift, which can actually be quicker for boxes and smaller furniture carried by hand, but makes very heavy single items harder to manage without a ramp or extra lifting help. Neither access style is universally better - it depends on what's actually being moved, which is another reason a carrier assessing your specific inventory is more reliable than picking a van size from a label.
Why bulky, irregular shapes beat the spec sheet
Cubic-metre figures assume efficient stacking - real furniture rarely stacks efficiently.
A published load-volume figure describes the maximum empty space in the vehicle, calculated as a simple box measurement. It doesn't describe how efficiently that space can actually be filled. Boxes stack well and leave very little wasted space. Furniture doesn't: a wardrobe, a sofa, a mattress or an armchair is an irregular shape that leaves gaps around it that smaller items can only partly fill, and some items - a mattress in particular - can't be stacked on top of much else without damage or an unsafe load.
In practice, this means a van's real-world usable capacity for a mixed household load is usually somewhat below its rated cubic volume, and the gap gets bigger the bulkier and more irregularly shaped the items are. A room full of boxed books and kitchenware will come close to filling a van's rated volume; a room with a sofa, two armchairs and a dining table will typically use the space far less efficiently, even if the total weight and a naive volume calculation suggest it should fit.
The practical fix is to describe your actual inventory - room by room, noting anything bulky or an unusual shape - rather than trying to translate a cubic-metre figure yourself. A carrier assessing a real list of items, including large or awkward pieces, will judge usable capacity and vehicle choice far more accurately than a volume-only calculation can.
Van size comparison at a glance
Typical figures across common UK van-hire specifications - exact numbers vary by model.
| Option or job scenario | What it includes | Main restriction | What to confirm before booking |
|---|---|---|---|
| SWB panel van | Roughly 5–8 m³ load volume (about 6.5–10.5 cu yd); payload commonly 800–1,200 kg | Compact load area suits boxes and light-to-medium furniture, not a full room of bulky items | Whether your inventory is mostly boxed/stackable or includes large single pieces |
| LWB panel van | Roughly 8–12 m³ load volume (about 10.5–15.7 cu yd); payload commonly 1,100–1,500 kg | Longer load floor than SWB, but still a sloped panel-van roofline, not a box shape | Load length against your longest items (e.g. a dining table or bed frame) |
| Luton van (3.5t box body) | Roughly 15–20 m³ load volume (about 19.5–26 cu yd); payload commonly 900–1,200 kg | Highest volume of the three, but payload isn't always higher than an LWB’s; tail lift reduces payload further by around 250 kg | Whether a tail lift is fitted, and whether your load is volume-limited or weight-limited |
| Heavy or dense materials (soil, rubble, tiles) | Weight limit is reached well before the van looks visually full | Payload, not volume, becomes the limiting factor for dense waste | Ask the carrier whether your load is being priced by weight rather than van fraction |
| Mixed household clearance with bulky items | A carrier assesses your room-by-room inventory rather than a single volume figure | Irregular shapes (sofas, wardrobes, mattresses) use space less efficiently than boxed items | Describe large or awkward items specifically when you request quotes, not just a room count |
When one van isn't enough: multiple trips vs a bigger vehicle
Sometimes two SWB runs make more sense than a single Luton booking, and sometimes it's the opposite.
If an inventory sits right at the edge of one van size, there are two practical routes: book the next size up, or run the smaller van for two trips. Which makes more sense depends on access and distance as much as volume - a single Luton trip is usually more efficient for a full house clearance with a long drive to a disposal site, while two SWB trips can work better for a smaller job with tight parking or a narrow residential street where a large box van is harder to position.
Weight is worth checking separately from volume here too. A load that's visually modest but includes dense materials - full bookcases, filing cabinets, or garden items like paving slabs - can hit a van's payload limit while there's still clear floor space left in the box, which is a weight problem rather than a volume one. Our garden clearance and builders & renovation waste clearance pages cover jobs where this comes up often, since rubble, soil and tiles are classic examples of weight-limited rather than volume-limited loads.
How load size fits our van-fraction pricing
houseclearance.co is a quote-matching marketplace - vehicle choice sits with the carrier, not with us.
houseclearance.co connects you with independent, licensed clearance carriers who quote on your job - we don't operate our own van fleet or send a specific vehicle ourselves. Because of that, carriers on our platform commonly price smaller jobs by van-load fraction rather than a flat per-item rate, using a standard 3.5-tonne Luton van as the 100% benchmark. Our prices page sets out that fraction table in detail, with a full Luton load benchmarked at 16 cubic yards and a 1,000 kg weight threshold - figures that sit comfortably within the broader 15 to 20 cubic metre, 900 to 1,200 kg payload range for 3.5-tonne Lutons described above, reflecting one specific operational assumption carriers work to rather than a universal spec for every Luton on the road.
If you're planning a move rather than a one-off disposal job, our downsizing and house clearance planning guide covers timing and inventory planning in more depth, and our house clearance checklist sets out the keep/donate/remove sorting process that naturally produces the inventory a carrier needs to judge van size accurately in the first place. The most reliable way to get the right vehicle for your job is still to describe the actual inventory - rooms, large items and anything unusually bulky - when you request quotes, rather than trying to name a van size yourself.
Frequently asked questions
The questions that come up most often when comparing van sizes.
What's the actual difference between SWB, LWB and a Luton van?
SWB and LWB describe the wheelbase length of a panel van - the load area sits within the van's normal body shape, with a sloped roofline over the cab. A Luton has a separate, taller box body built over and ahead of the cab, which is why it carries noticeably more volume than an LWB panel van despite sometimes having a similar or lower weight payload. The names describe body shape and construction, not a fixed capacity number, which is why two vans both called "LWB" can still differ in load volume.
How much can an SWB van actually carry?
A short-wheelbase panel van typically offers somewhere in the region of 5 to 8 cubic metres of load volume, with a payload commonly between about 800 and 1,200 kg depending on the specific model. That's enough for a small flat's worth of boxes and light furniture, or a handful of large single items, but exact figures vary by manufacturer and roof height, so it's worth checking the specific van's spec rather than assuming every "SWB" is identical.
Is a Luton van always bigger than an LWB panel van?
In volume, yes - a Luton's load volume commonly falls between about 15 and 20 cubic metres, well above an LWB panel van's roughly 8 to 12 cubic metres, because the box body is taller and extends over the cab. In payload, not necessarily - a 3.5-tonne Luton's payload is often around 900 to 1,200 kg, which can be similar to or even lower than some LWB panel vans, since the heavier box body itself eats into the vehicle's overall weight allowance.
Why would loading time or trips matter more than the van's label?
Because bulky, awkwardly shaped items rarely stack as efficiently as boxes do, so a van rated for a certain cubic capacity on paper can still run out of usable space well before that figure is reached. A wardrobe, a sofa or a mattress leaves irregular gaps around it that smaller items can't always fill, which is why real loads often need more space, or an extra trip, than a straightforward volume calculation suggests.
Does houseclearance.co send a specific van size to my job?
houseclearance.co is a quote-matching platform connecting you with independent, licensed clearance carriers, so vehicle choice sits with the carrier who takes on your job, not with us directly. When you request clearance quotes, describing your inventory - rooms, large items and approximate volume - lets carriers assess the right vehicle and crew themselves, which is more reliable than you trying to pre-select a van size from a label alone.
