We often hear about (and get asked about) the complexities of putting Kombi's through the business. Kombi's are often seen as the perfect answer for a self-employed tradesman or small business owner. Proper load space for tools and stock during the week, plus a second row of seats so the same van does the school run or a weekend away. One vehicle, two jobs.
Before we get into it: we're not accountants, and this isn't tax advice. It's our general understanding of the current rules, built up from our own reading and from conversations with customers and their accountants. If you're making a real decision about your own van and your own books, talk to an accountant who knows your specific situation. What we can offer is a clearer, more current picture than the mixed messages that tend to do the rounds at van shows and in forums.
Why people get mixed answers
The old rule of thumb was: if the van's payload is over a tonne, a T32 rather than a T30, say it's a commercial vehicle, seats or no seats. That's not a bad instinct. It's genuinely how VAT treats vans, and it still applies today: buy a genuine one-tonne-plus payload kombi, and the VAT on the purchase can still generally be reclaimed in the normal way, same as any other van.
The confusion creeps in because VAT isn't the only tax question, and because the answer genuinely depends on how you're set up. A sole trader and a limited company director are asking two different questions, even though it sounds like the same one.
If you're a sole trader, this mostly isn't the problem you think it is
Most of the noise around this topic is regarding the Benefit in Kind rules, the car-versus-van fight, the court case we get to below is actually an employment tax question. It applies where a limited company provides a vehicle to an employee or director. If that's your setup, keep reading, because it does matter to you.
But if you're a sole trader running your own van through your own books, there's no employer handing you a "benefit" to be taxed on, so the sharp car vs van decision doesn't really apply in the same way. Your question is simpler, How much of the running cost and how much of the vehicle's value can you fairly claim against your profits, given the mix of business and private use. That's a matter of reasonable portioning of mileage, usage patterns, evidence, rather than a single yes/no test on the vehicle itself. It's a softer, more forgiving standard, and for a lot of our customers, this is genuinely better news than some forum chat suggests.
If you're a limited company, here's what's actually at stake
If you are drawing a kombi as a benefit through a limited company, the position tightened in 2020 and it's worth knowing the real numbers, because "you can't do this" isn't quite right either. It's more that the downside is bigger than people assume, and it's worth pricing in rather than guessing at.
The often cited case is Payne, Garbett and Coca-Cola European Partners v HMRC, decided by the Court of Appeal in 2020. Coca-Cola gave field technicians modified VW Transporters and a Vauxhall Vivaro, kitted out with a second row of seats and some racking. HMRC said these counted as cars, not vans, for tax purposes, and the Court of Appeal agreed. The reasoning: the legal test asks whether a vehicle is "primarily suited" to carrying goods, and "primarily" means first and foremost, not just "quite good at it." Once you've added a second row of seats and windows, a vehicle does two jobs equally well, and that's enough to fail the test.
Here's why the numbers matter. If HMRC accepts the vehicle as a van with private use, the Benefit in Kind charge is a flat £4,020 for 2025/26, taxed at your threshold rate, around £800 a year for a basic-rate taxpayer, or £1,600 for a higher-rate one. If it gets reclassified as a car, the charge is based on list price and CO2 emissions instead, and for a mid £30k kombi that can mean a taxable benefit north of £10,000 a year, several times the van charge. That's the real financial gap the classification question is protecting: not "allowed or not allowed," but a genuinely bigger tax bill if it goes the wrong way.
Worth flagging: HMRC's litigated cases in this space tend to be large fleets under formal audit, like Coca-Cola's, where the volume makes the fight worth having. Smaller businesses are only really likely to encounter this through routine PAYE or P11D checks than a dedicated investigation. That's not a reason to assume you'll never be asked about it, but it's useful context for weighing up the actual risk with your accountant, rather than treating it as a complete gamble.
Tongue in cheek for a second: every case I could find on this involved a multinational with a fleet of hundreds, under a formal HMRC audit that presumably cost more in professional fees than the tax at stake. I couldn't find a single example of HMRC turning up at a sole trader's van to count the windows. Make of that what you will, we're not saying it couldn't happen, just that it doesn't seem to be how anyone's actually been caught so far.
Does the new electric Transporter change any of this?
Worth a mention, given how much better the range is on the new e-Transporter and e-Transit Custom compared to the early electric vans. It's now genuinely usable for a working day, not just a novelty. And it happens to change this whole conversation quite a lot, because electric vehicles get much friendlier tax treatment across the board.
If HMRC accepts it as a van, a zero-emission van currently carries a nil Benefit in Kind charge, no tax at all, regardless of private use. And even in the worst case, if it gets reclassified as a car under the same Coca-Cola reasoning, electric cars are taxed at just 3% of list price for 2025/26 (creeping up gradually to 4%, then 5%, then 7% over the next few years) rather than the 30-37% an equivalent diesel would attract. So for an electric kombi, the entire car vs van argument that costs a diesel driver thousands of pounds a year barely moves the needle either way.
A side note, since we get asked this a lot in the context of weight and range: our Switch unit weighs around 80kg in the SWB version, which is roughly the same as having one more passenger sat in the back. It's not nothing, but it's not the kind of weight that meaningfully dents an electric van's range either. If you're weighing up an e-Transporter or e-Transit Custom and wondering whether fitting a storage system will eat into your range, the honest answer is: not by much.
Are our Switch units allowable as a business expense?
Since we're on the subject of tax, it's worth addressing this directly, because most of the tradespeople we work with put their Switch or dual deck system through the business as exactly what it is on the invoice: racking and storage equipment, nothing more.
That's a fair way to treat it, and for good reason. Racking, shelving, drawer systems and similar equipment fitted into a van are treated as plant and machinery for tax purposes, entirely separately from the van's own car vs van test above. Fitted equipment like this normally qualifies for full relief in the year you buy it through the Annual Investment Allowance, the same way a tool box, ladder rack, or set of shelving would. It's a genuinely different question from everything else in this post, and as far as we can find, there's no case law or HMRC guidance suggesting racking and storage systems get any special scrutiny.
In our case, that's reinforced by what the units are actually for during the working day: a full-height or mini bulkhead for security, a drawer system that improves access to tools and materials, and enough clear floor space with the seats down to carry sheet materials. That's a hard case to argue is anything other than business equipment.
The one honest caveat: the same general principle that applies to any dual-purpose asset technically applies here too, if there's identifiable personal use of the bed function, in strict theory a sliver of the cost relates to that rather than pure business use, in the same way a laptop used partly for personal browsing would be apportioned. In practice this is a soft, judgement-based question rather than a hard test, and we're not aware of HMRC ever having pushed on this specifically for van racking or storage systems. It's a much lower-risk category than the vehicle question above, just not a guarantee in theory.
Does adding seats to a plain panel van get around it?
We hear this one a lot, because some converters sell exactly this route: buy a panel van, retrofit a second row of seats and windows afterwards, rather than buying the equivalent factory kombi, on the basis that on paper it's still registered as a panel van.
Based on the Coca-Cola case, we don't think this holds up, and it's worth knowing why. Two of the three vehicles in that case were genuine factory Kombis, but the third, the Vivaro, was a standard panel van that Coca-Cola had fitted with seats and a window afterwards. The court didn't treat it any differently. It looked at the vehicle in the state it was actually used, seats and windows in, and taxed all three the same way. If it were ever tested, a retrofit conversion looks very likely to be assessed on the same basis as a factory kombi, whatever the registration document says.
Also worth a quick separate mention: double-cab pickup trucks got their own widely-reported rule change from April 2025, reclassifying them as cars for BIK and capital allowances (with some protection for vehicles bought before then). That's a related idea but a different rule aimed specifically at pickups, and doesn't change anything that wasn't already settled for kombi vans back in 2020.
Where we fit into this
Whichever position you and your accountant land on, the practical question doesn't go away: how do you actually use the space in the van day to day. That's the bit we can help with, regardless of what's in the back or what box HMRC puts your vehicle in.
Most of our customers run kombis with the rear seats left in, and our Switch range is built for exactly that, secure tool and equipment storage that works over the top of the existing seats, switching to a full-size bed for evenings and weekends. But plenty of our customers turn up with a plain panel van, no seats at all, and the same units work just as well for them: same storage, same functionality, without needing anything else fitted.
For anyone running a Transit Custom or similar crew-cab, with a bulkhead already fitted behind the second row of seats, our dual deck system is built for that setup specifically giving you a properly defined, secure storage area behind the bulkhead. The one thing it doesn't do is convert into a bed, simply because the bulkhead divides the space in a way that a full-length platform can't work around. If sleeping space matters to you as well as storage, that's worth knowing before you commit to a crew-cab layout with a fixed bulkhead. Also worth knowing that a Transits seats do bot fold int he same way a kombi's seats would, so if you have the intention of buying a Transit and removing the bulkhead, its not as simple as expected.
If you're not sure where your own van stands, that conversation is worth having with your accountant, armed with the actual numbers rather than the version that gets passed around at the van show. And if you're after proper storage and a comfortable bed out of the same vehicle, seats in, seats out, or bulkhead behind them, take a look at the range and see what fits.
