Card Machine Rental vs Purchase UK 2026: Which Works Out Cheaper?

The Two Models: How They Actually Work

In the UK market there are broadly two ways to get a card machine. You can buy a device outright and own it, or you can rent one through a provider on a monthly rolling agreement. Both models have very different cost structures, and comparing them is not as simple as looking at the sticker price on the hardware.

With an outright purchase, you pay for the device up front and then pay transaction fees on each card sale. With rental, the hardware is included in your monthly fee and you typically get support, replacements, and software updates bundled in. The real cost of either model only becomes clear when you factor in transaction fees over time.

The Outright Purchase Option

The cheapest card readers you can buy are small Bluetooth devices that pair with your phone. A Square Reader costs around £19 plus VAT and a SumUp Air is roughly £29. These are genuinely affordable entry points, and if you only take a handful of card payments a week, they can make sense.

The catch is the transaction fees. Square charges 1.75% per transaction. SumUp charges 1.69%. Those percentages sound small, but they compound quickly as your card turnover grows. On £5,000 per month in card sales, you are paying £87.50 to Square or £84.50 to SumUp in transaction fees alone.

There is also a practical limitation. These readers rely on your phone for connectivity and display. They are fine for a craft stall or mobile hairdresser doing low volumes, but they feel unprofessional at a busy counter and they do not print receipts.

The Rental Model: Dojo Through CapExpand

When you get a Dojo card machine through CapExpand, the hardware is included in your monthly fee. There is no upfront cost for the terminal itself. You get a proper countertop or portable device with a built-in screen, receipt printer, and 4G fallback.

Dojo's transaction fees are competitive for established businesses and typically come in lower than the flat-rate providers, especially at higher volumes. Rates are tailored to your business, so I cannot quote an exact figure here, but for most businesses processing £5,000 or more per month through CapExpand, the total monthly cost (fees plus terminal) works out cheaper than a “free” reader with higher transaction fees.

The 12-Month Cost Comparison

Let us run through a realistic example. Say your business processes £8,000 per month in card payments. Here is roughly what each option costs over a year:

The numbers shift even further in Dojo's favour as your monthly volume increases. At £15,000 per month, the gap between a flat-rate reader and a properly priced terminal is hundreds of pounds per year.

The 24-Month Picture

Over two years the maths becomes even starker. That £19 reader is not really £19 when you have paid £3,360 in transaction fees over 24 months at 1.75%. The hardware cost is a rounding error compared to the ongoing fees, which is exactly how those providers make their money. Low entry price, higher long-term cost.

With Dojo through CapExpand, your transaction rate is set up front and stays competitive. Over 24 months, a business processing £8,000 per month will typically save several hundred pounds compared to the flat-rate alternatives, while also getting a professional-grade terminal, next-day payouts, and proper support.

What People Forget: The Hidden Costs of Buying

There are costs to owning a device that are easy to overlook. If your purchased reader breaks after the warranty period, you buy another one. If the battery degrades (and they all do after 12 to 18 months of heavy use), you are replacing it out of pocket. Software updates may eventually stop, leaving you with an outdated device.

With Dojo's rental model, faulty devices get replaced at no extra charge. You always have the latest software and security patches. If something goes wrong, you call support and they send a replacement. That peace of mind has real value, especially if you depend on card payments for the majority of your revenue.

Transaction Fees Matter More Than Hardware Price

This is the single most important takeaway from this article. The cost of the device itself is almost irrelevant compared to what you pay in transaction fees over time. A £19 reader with 1.75% fees costs more than a £0-upfront terminal with 1.2% fees within the first few months of trading.

If you are processing less than £1,000 per month, the difference is small enough that convenience might be your main consideration. But once you cross £3,000 to £5,000 per month, every 0.1% in transaction fees starts to add up meaningfully.

When Buying Makes Sense

I will be straightforward about this. If you are a sole trader doing occasional markets or a mobile therapist taking five to ten card payments a week, a SumUp or Square reader is a reasonable choice. The volumes are low enough that the higher transaction fees do not add up to much, and the zero monthly commitment gives you flexibility.

But here is where I see businesses make a mistake: they start with a cheap reader, their volumes grow, and they never reassess. Six months later they are processing £10,000 a month through a device that is costing them an extra £50 to £80 per month in fees compared to what they would pay with a properly priced terminal.

When Rental Wins

For any established business with consistent card turnover above £5,000 per month, a rental terminal through a provider like Dojo almost always works out cheaper on a total cost basis. You get lower transaction rates, professional hardware, support, and replacements all bundled in.

Watch Out for Long Lock-in Contracts

One thing to watch with rental is the contract length. Some traditional providers lock you into three or even five year terms with hefty early termination fees. That is not the case with Dojo through CapExpand. Dojo offers straightforward terms without the aggressive lock-in periods you might have experienced with legacy providers like Worldpay or Barclaycard.

Always read the contract terms before signing. If a provider will not let you leave without paying hundreds of pounds in penalties, that is a signal they are not confident their service will keep you around voluntarily.

The Bottom Line

Do not get distracted by the upfront price tag. A card machine that costs nothing up front but charges 1.75% per transaction is more expensive over 12 months than a rental terminal with lower rates for any business doing reasonable volume. Run the numbers for your specific turnover before making a decision.

For most established UK businesses, renting a Dojo terminal through CapExpand gives you the best combination of low total cost, professional equipment, and hassle-free support. If you are just starting out and volumes are very low, a budget reader is fine for now, but set a reminder to review once your monthly card turnover passes the £3,000 mark.
