Advertisement
By Chandraketu Tripathi  |  Updated April 2026
Accepting card payments is now essential for any UK business — cash use has fallen below 15% of all transactions. In 2026, small businesses have more affordable options than ever: portable card readers from SumUp, Square, and PayPal Zettle cost £19-49 upfront with no monthly fees, charging only 1.69-1.75% per transaction. Traditional terminal rental from banks costs more monthly but offers lower per-transaction rates at higher volumes. This guide helps you choose the right card payment solution for your business.

What to Consider When Choosing a Card Machine UK

  • Transaction volume: Under £5,000/month — buy outright (SumUp, Square). Over £10,000/month — monthly rental may be cheaper overall
  • Connectivity: Bluetooth (connect to phone) for portable traders; WiFi + 4G for fixed premises; check signal in your location
  • Battery life: SumUp Air battery life ~500 transactions; Square Reader ~12 hours; important for busy market traders
  • Payout speed: SumUp pays to bank within 1-3 working days; Square pays next day; PayPal Zettle same day to PayPal balance
  • EPOS integration: If you need a full point-of-sale system (till, inventory, receipts), Square has the strongest free POS software
  • Contactless limits: All major UK card machines process contactless up to £100 (the current UK contactless limit)
  • Contract length: SumUp, Square, Zettle — no contract; rental terminals typically 12-24 month contracts

Frequently Asked Questions

What is the best card machine for a small business UK 2026?
SumUp Air is the best all-around card machine for most small UK businesses in 2026: £39 upfront, 1.69% per transaction (the lowest among the major portable readers), no monthly fees, and no contract. Square Reader at £19 is the cheapest to start if you want the absolute lowest entry cost. For businesses processing over £10,000/month in card payments, a monthly rental terminal from Worldpay or Barclaycard may become more cost-effective.
How much do card machines cost UK?
Portable card readers (no monthly fee, pay per transaction) cost £19-59 to purchase. Monthly rental terminals from banks and payment processors cost £15-40/month with lower per-transaction rates (0.8-1.5%). The right choice depends on your monthly card turnover — buy-outright readers are cheaper below approximately £5,000-8,000/month; rental terminals become competitive above this level.
What are the fees for card machines UK?
SumUp: 1.69% per transaction, no monthly fee. Square: 1.75%, no monthly fee. PayPal Zettle: 1.75%, no monthly fee. Monthly rental terminals: 0.8-1.5% per transaction plus £15-40/month rental. All fees are subject to card type — some premium and corporate cards carry additional interchange fees with some providers.
Do I need a card machine or can I use my phone UK?
You can accept card payments using only a smartphone with some providers — Square and SumUp both offer virtual terminal options (type in card details) or QR code payments. However, a dedicated card reader with tap/chip payments is more professional, faster, and required for contactless payments. A card reader also provides better fraud protection as it reads the chip rather than relying on manually entered card details.
