The van that “costs nothing” is usually the expensive one.

It is a story worth telling because it is so common — the same situation comes up again and again with sole traders running an older van. The van is owned outright, or sitting on a small finance payment, and on that basis it feels close to free. There is no large monthly cost to point at, so when the idea of hiring comes up at a few hundred pounds a month, it looks like the expensive option by a distance.

Then the van starts to age. On one working van of this kind, the gearbox failed — a repair north of £2,000. On a van of that age and value, that is not really a repair decision at all: spend the £2,000 or the van is worth little more than scrap. Either way the money is gone. The same year's MOT added another £500 — not for anything dramatic, just the accumulating wear of an older vehicle: bushings, drop links, the parts that quietly reach the end of their life all at once on a van that has done the miles.

None of that included the part that hurts a sole trader most, because it never appears on a bill. While the van was off the road, the work stopped. There was no second vehicle to fall back on. For a one-person business billing a typical day rate — take a conservative £200 a day as an illustration — even three or four days waiting on a repair is £600–£800 of work that simply did not happen, on top of the repair itself. The van that “costs nothing” had, across the year, cost thousands in repairs and lost earning days combined — it just never arrived as a single, visible figure anyone could plan around.

That is the trap this page is about: the difference between what an old van appears to cost and what it actually costs once the failures, the wear bills, and the lost days are added together.

For a sole trader or a new business, the maths on vehicle hire usually starts in the wrong place. The comparison feels like this: the current van is owned outright, or sitting on a small finance payment on a used vehicle, so it costs almost nothing each month. A flexi hire van at, say, £450 a month feels like an enormous jump from there. On that basis, hiring looks like the expensive option and keeping the old van looks like the careful one.

The problem is that the old van is not costing nothing. It is costing a fortune — just not in a way that shows up as a tidy monthly figure, which is exactly why it gets left out of the comparison.

The big-ticket failures. On a van that is five to ten years old and working for a living, the serious failures are not a question of if but when. A turbo failure runs anywhere from £450 to £3,000, with most jobs landing around £800–£1,200 — and in a bad case, debris from the turbo enters the engine and the bill becomes a new engine. A timing chain is typically £750–£1,000 and can exceed £2,000 on more complex engines; a cambelt with the water pump done at the same time is around £700. A gearbox failure can run well past £2,000 — and on an older van that is the cliff edge, because the repair can cost more than the vehicle is worth, leaving the owner choosing between a four-figure bill and scrapping a van that still has work to do. Any one of these arrives with no warning, on no schedule, and at the worst possible moment.

The accumulating small stuff. Underneath the headline failures is a steady drip that most owners never add up. On an older van, the MOT stops being a formality and starts being a bill: drop links, bushings, engine mounts, brakes, exhaust components — items that wear out together on a high-mileage vehicle. It is entirely normal to hand over £500 in a single MOT on suspension and steering parts alone, and then face the next set a few months later. Even a battery is no longer a small cost: a modern van with a stop-start system needs an AGM or EFB battery at £150–£400 fitted, comfortably double a standard battery, and it cannot be downgraded to a cheaper type without the system failing. None of these are disasters on their own. Added across a year, they are a second, invisible finance payment.

The cost nobody invoices: downtime. For a sole trader this is the one that really hurts, and it never appears on any repair quote. When the van is in the garage for three days waiting on a turbo or a gearbox, the sole trader is not earning. There is no second vehicle, no fleet to absorb the gap. The repair bill is only half the cost — the lost days are the other half, and for a one-person business those lost days can dwarf the repair itself. A genuinely unreliable van does not just cost money to fix; it costs money every day it is off the road.

The “buy another cheap van” trap. Faced with the failing old van, the instinct is often to buy another cheaper used van — usually on a hire purchase deal, because the cash isn't there to buy outright. It feels like the safe middle ground: newer than the old one, only a modest monthly payment. But this is where the trap closes. Twelve to eighteen months on, the “new” van is showing the same accumulating faults as the old one — because a cheap used van is, by definition, already well into its wear curve. Now the picture is worse, not better: the same building repair costs, plus a finance payment that is often slightly higher than before, plus — critically — no way out, because the van is tied into a three or four-year HP agreement. The owner is now contractually committed to a vehicle they cannot easily shift, carrying every repair bill themselves, with the annual MOT and the next battery and the next failure all still landing on them. They have taken on the commitment of finance without the reliability of new, and the maintenance burden of ownership without the freedom to walk away.

The honest comparison. When you total it properly — the unpredictable big-ticket failures, the accumulating MOT and wear bills, and the earning days lost to downtime — the “£0 a month” old van, or the cheap used van on finance, frequently costs more per year than a flexi hire van would. And it costs it in the worst possible shape for a small business: large, sudden, unbudgeted, and arriving exactly when the van is off the road and the owner is not earning.

Flexi hire turns all of that into a single, predictable monthly figure with servicing, maintenance and breakdown cover built in — and, crucially, a replacement vehicle when something goes wrong, so the downtime that does the real financial damage largely disappears. The monthly cost is visible and higher; the total annual cost is often lower and, just as importantly, it is known in advance.

The honest caveat. This argument applies to the aging, unreliable van — not every owned van. A reliable, paid-off vehicle with low mileage and no looming big-ticket repairs is genuinely cheap to run, and for that owner, keeping it is the right call. The point is not that owning is always wrong. It is that there is a specific, recognisable moment — when the failures start, when the MOT bills start climbing, when the downtime starts costing real work — at which keeping the old van, or buying another cheap one on finance, stops being the economical choice and starts being the expensive one. Recognising that moment is the whole decision.

There is one cost of an unreliable van that never appears on any quote, and for a sole trader it is the most dangerous of all: the work you lose when you do not turn up.

A sole trader is the business. There is no brand to hide behind, no colleague to cover the job, no depot to send another van from. When the vehicle will not start on the morning of a job, it is not an inconvenience — it is a customer left waiting, a day's work handed to someone else, and, worst of all, a reputation quietly damaged. It happens: a sole trader loses a good customer not because of the quality of their work, but because the van let them down at the wrong moment, and the customer simply could not afford to wait again. In a business that runs on word of mouth, that does not just cost one job. It costs the repeat work and the referrals that would have followed.

This is why the “hire is expensive” instinct gets the maths backwards. The owned van's cost is not only the repair bills and the lost days — it is the slow erosion of the one thing a sole trader cannot rebuild with a credit card: the trust of the customers who keep them in work. A reliable vehicle, with breakdown cover and a replacement if something goes wrong, is not a luxury for a one-person business. It is reputation insurance.

Sole traders are often unsure what they are allowed to claim on a vehicle, and the rules genuinely matter here because the wrong choice can cost money. The key thing to understand is that there is a fork, and you cannot have both sides of it.

Option one: the simplified mileage method. You claim a flat rate per business mile — 45p per mile for the first 10,000 business miles in the year, then 25p after that — and that single figure is meant to cover everything: fuel, repairs, servicing, insurance, the lot. If you use this method, you cannot also claim the actual running costs or hire charges on top. It is simple and it suits low-mileage, lower-cost vehicles, but for a sole trader doing real business miles in a van that is costing real money to run, it often leaves money on the table.

Option two: actual costs. You claim the genuine running costs of the vehicle instead — and this is where hire charges sit. Van hire charges are an allowable business expense, deducted in full against your profits as you pay them, the same as fuel, insurance, servicing and repairs. For a working van, claiming actual costs is frequently the better route, and flexi hire fits it cleanly: the monthly charge is simply deducted as a business expense, month by month, with none of the complexity of capital allowances.

Where buying gets more complicated. If you buy a van outright or on hire purchase, HMRC treats you as the owner from day one — even under HP, the capital allowance is calculated on the full price of the van, not on your monthly payments. That can be valuable through the Annual Investment Allowance, but only if you are making enough taxable profit to use the relief, and only if you are claiming actual costs rather than mileage. And any private use of the van has to be stripped out: you can only claim the business proportion, and HMRC expects a mileage log to back it up.

The honest summary: for most working sole traders, claiming actual costs beats the mileage method, and within that, hire charges are the simplest possible thing to claim — a clean monthly expense, fully deductible, no capital allowance calculations, no private-use apportionment headaches on the vehicle's value, no records to defend years later. (Note: tax treatment depends on individual circumstances and this is general information, not tax advice — a sole trader should confirm their own position with their accountant.)

The “owning is cheaper” belief usually rests on the monthly cost alone. Once the full picture is in view, it rarely holds for a sole trader.

If you are not VAT registered — and many sole traders are not — buying is meaningfully more expensive than the headline. You pay the full VAT on the van and you cannot reclaim a penny of it. On a £30,000 van that is £6,000 of pure cost that a VAT-registered business would get back but you simply absorb. It quietly makes the purchase price a fifth higher than the sticker, and it is the single most overlooked factor when a non-registered sole trader compares buying with hiring.

If you are VAT registered, you can reclaim the VAT — but you still have to fund it upfront. Under hire purchase, the VAT on the full price falls due as a lump sum at the start, not spread across the payments, and you reclaim it on your next quarterly return. For a sole trader that is a real cash demand at exactly the moment money is tight.

Either way, the capital is yours and so is the risk. Buying ties up money — or commits you to finance in your own name, because as a sole trader there is no company to stand behind the debt; it is personally yours. You then carry every cost the old van taught you about: the depreciation, the repairs as it ages, the MOT bills, the downtime, the eventual replacement. Everything that made the old van expensive comes back, just on a newer vehicle and on a longer timescale.

Set against that, flexi hire is a single monthly figure with maintenance and breakdown built in, fully deductible as a business expense, with no capital tied up, no personal finance debt, and no depreciation or resale to worry about. The monthly number is visible and feels larger. The total cost, and the risk, is very often lower.

Most sole traders who move to flexi hire do it partly as a safety net. The thinking is defensive: if work dries up, I can hand the van back, so I am not stuck paying for a vehicle I cannot use. That reassurance is real, and it matters.

But the interesting thing is what actually happens. Far more often, the work does not dry up — it grows. And the flexibility that was meant to protect against the downside turns out to be exactly what enables the upside. The sole trader who can take a bigger van the moment a bigger job appears, add a second vehicle for a busy spell, or switch to a different vehicle type as the work changes — all without a finance application, a deposit, or a three-year commitment — can say yes to things an owned-van sole trader has to hesitate over.

This is what makes flexi hire genuinely suited to a sole trader testing whether they can take on bigger work. Buying or financing forces the bet upfront: you commit to the vehicle, and the cost, before you know whether the bigger work will stick. Flexi hire lets you prove it first. Take the bigger van for a month or two, see whether the larger jobs come good, scale back with no penalty if they do not, commit further if they do. It turns a daunting leap into a series of low-risk steps — which is exactly how a sole trader should be able to grow.

So the honest reframing is this: flexi hire is not just insurance against things going wrong. For most sole traders, it is the thing that lets them grow when things go right — without betting the business on a vehicle before the work is there to justify it.

The honest caveat. If you have a reliable, paid-off van with plenty of life left and your work is stable and predictable, keeping it is genuinely the lowest-cost option, and this page is not arguing otherwise. The case for flexi hire applies when the old van is becoming a liability, when reliability is starting to cost you work, or when you are trying to grow and need the freedom to move. That is the moment the maths — and the missed opportunities — tip the other way.
