Card Machine Comparison Guide UK 2026
Comparing Card Machine Providers UK
Quick Answer: The best card machine provider depends on your business type, transaction volume, and specific needs. Pay-as-you-go providers (SumUp, Square, Zettle) suit low-volume businesses with no monthly fees. Traditional providers (Worldpay, Barclaycard) suit high-volume businesses with better transaction rates.

How to Choose the Right Card Machine Provider
Decision Framework
Choose pay-as-you-go (SumUp, Square, Zettle) if:
- You process under £5,000 monthly in card payments
- You want no monthly fees or contracts
- You need quick setup with minimal paperwork
- You’re testing card payment acceptance
- You have seasonal or irregular trading patterns
Choose traditional merchant account (Worldpay, Barclaycard) if:
- You process £5,000+ monthly in card payments
- You want the lowest possible transaction rates
- You need advanced reporting and integrations
- You operate multiple locations
- You need comprehensive business support
Key Factors to Compare
1. Transaction Fees vs Monthly Volumes
Calculate your break-even point. Example:
- Pay-as-you-go at 1.75%: £10,000 monthly = £175 in fees
- Traditional at 1.2% + £20 monthly: £10,000 monthly = £120 + £20 = £140 in fees
- Savings with traditional: £35/month (£420/year)
As volume increases, traditional providers become increasingly cost-effective.
2. Contract Commitment
No contract (pay-as-you-go):
- Cancel anytime
- No early termination fees
- Flexibility to switch providers
Fixed-term contract (traditional):
- Typically 1-3 years
- Early termination fees (£200-£1,000+)
- May include rate guarantees
3. Terminal Costs
Pay-as-you-go: Buy terminal outright (£29-£299)
Traditional: Rental (£10-£30/month) or purchase (£100-£500)
Calculate 2-year total cost to compare fairly.
4. Settlement Speed
- Next-day: SumUp, Zettle, most traditional providers
- 2-4 days: Square (initially), Revolut
- Same-day available: Some traditional providers for established businesses
5. Feature Requirements
Basic needs (card acceptance only): Any provider works
EPOS integration: Square, traditional providers with integrations
Inventory management: Square excels here
Multi-currency: Revolut Business best option
Online payments: Most providers offer this, compare rates
6. Support Quality
Pay-as-you-go: App-based support, email, limited phone support
Traditional: UK-based phone support, dedicated account managers for larger businesses
Common Comparison Mistakes
1. Comparing Headline Rates Only
1.75% with no monthly fees might cost more overall than 1.2% with £20 monthly fees if you process £5,000+ monthly. Calculate total costs based on your volumes.
2. Not Considering Growth
If you expect to grow significantly, choose a provider that scales well. Pay-as-you-go works initially but becomes expensive at higher volumes.
3. Ignoring Integration Needs
If you need EPOS integration, ensure the provider supports your chosen EPOS system. Square’s built-in EPOS is excellent for restaurants and retail.
4. Overlooking Contract Terms
3-year contracts with traditional providers can be restrictive. If you value flexibility, pay-as-you-go may be worth slightly higher transaction fees.
5. Focusing Only on Cost
Cheapest isn’t always best. Consider support quality, reliability, settlement speed, and feature set alongside costs.

Card Machine Comparison – Frequently Asked Questions
Which card machine provider is cheapest?
Revolut Business has the lowest transaction fees at 1%, but requires a Revolut Business account. For pay-as-you-go without account requirements, SumUp at 1.69% is most competitive. For high-volume businesses, traditional providers with custom rates often work out cheaper overall despite monthly fees.
Is SumUp better than Square?
SumUp is better for basic card acceptance with slightly lower fees (1.69% vs 1.75%). Square is better if you need integrated EPOS, inventory management, or advanced business features. SumUp is simpler and cheaper, Square is more feature-rich.
Do I need a contract for a card machine?
Pay-as-you-go providers (SumUp, Square, Zettle) require no contracts. Traditional providers (Worldpay, Barclaycard) typically require 1-3 year contracts. No-contract options offer flexibility but may cost more at high volumes.
Can I switch card machine providers easily?
With pay-as-you-go providers, yes – simply stop using the service. With traditional providers on contracts, you may face early termination fees. Always check exit clauses before signing. After contracts end, switching is straightforward.
Which provider has the best customer support?
Traditional providers (Worldpay, Barclaycard) typically offer better UK-based phone support. Pay-as-you-go providers rely more on app-based support and email. For businesses needing reliable phone support, traditional providers are better.
Do all providers accept the same card types?
Yes, all major UK providers accept Visa, Mastercard, and contactless payments. Most also accept American Express, though some charge higher fees for Amex transactions. Digital wallets (Apple Pay, Google Pay) are universally supported.
What is the fastest way to start accepting card payments?
Pay-as-you-go providers offer same-day or next-day setup. SumUp, Square, and Zettle can have you accepting payments within 24 hours. Traditional providers take 5-7 days due to more comprehensive underwriting and terminal delivery.
Can I use multiple card machine providers?
Yes, there is no restriction on using multiple providers. Some businesses use pay-as-you-go for mobile work and traditional providers for fixed locations. However, managing multiple providers adds administrative complexity.
Which provider is best for restaurants?
Square excels for restaurants due to integrated table management, order tracking, and kitchen display systems. Traditional providers with portable terminals work well for established restaurants. SumUp suits small cafés wanting simple table-side payment.
How do I know if I am paying too much?
Compare your effective rate (total monthly fees ÷ monthly processing volume) against provider offerings at your volume level. If paying over 2% effective rate on volumes above £10,000 monthly, you are likely paying too much and should review alternatives.
