Cheapest Card Machines UK 2026: True Cost Comparison

Square Reader is the cheapest at £19+VAT one-off cost with no monthly fees. Transaction fee is 1.75%. SumUp Solo is £29+VAT with 1.69% fees. Both have no contracts or monthly charges, making them ideal for low-volume businesses.

Yes for low-volume businesses (under £5,000/month in card sales). If you process over £5,000/month, Dojo usually works out cheaper: it publishes a 1.2% blended rate for businesses under £100,000 a year in card turnover, with a custom quote above that, and terminals are bought upfront or hired from £15/month. Calculate your total cost: hardware + monthly fee + (sales × transaction %).

Even "cheap" card machines can have: PCI compliance fees (£5-15/month), chargeback fees (£15-25), minimum monthly service fees, terminal rental vs purchase costs, early termination fees. Always ask for ALL costs upfront.

Some providers offer "free" terminals if you commit to a contract. Reality: The cost is built into higher transaction fees or minimum monthly fees. True cost over 24 months often exceeds buying outright.

Example: £20,000/month sales at 1.75% = £350/month = £4,200/year. Dojo publishes a 1.2% rate under £100,000 a year in card turnover and quotes a custom rate above (we have seen quotes as low as 0.29% at high turnover) - at £20,000/month the saving comfortably outweighs the hardware cost. Always calculate based on YOUR volume.

Virtual terminals (take payments by phone) often cheaper than physical machines: £10-20/month + 1.5-2.5% fees. Good for businesses taking phone/mail orders. No hardware cost at all.

Not always. Square and SumUp have excellent app-based support despite low costs. However, premium providers (Worldpay, Barclaycard) offer dedicated account managers and faster issue resolution for complex businesses.

Yes! Providers negotiate based on volume. Processing £20,000+/month? You can often get 0.2-0.5% rate reductions. We negotiate on your behalf using our buying power across multiple clients.

No - Visa and Mastercard set interchange fees (0.3-1.5% of transaction). This is unavoidable. Provider fees are charged ON TOP of interchange. The cheapest providers just add less markup.

Calculate: (Hardware cost ÷ 36 months) + Monthly fees + (Monthly sales × Transaction %). Example: £29 hardware, £0 monthly, £10k sales, 1.69% = £0.81/month + £169 = £169.81/month total.
