More UK businesses are moving away from traditional card networks in favour of Pay-by-Bank APIs. The promise? Lower costs, fewer chargebacks, and much faster settlement.

But not all providers offer the same speed or the same infrastructure.

TrueLayer and Volt are two of the UK’s top contenders in the open banking space, each providing powerful account-to-account (A2A) payment capabilities. Both claim to offer “instant” settlement. Yet under the hood, their approaches differ: one prioritises full-stack Open Banking access with developer control, while the other optimises for real-time payment speed through network-level routing.

If you’re deciding between TrueLayer vs Volt, this comparison will help you understand how they perform in practice, especially when it comes to:

  • Actual settlement times across UK banks
  • API capabilities and use case alignment
  • Which is better suited for recurring payments, batch payouts, or ecommerce checkout flows

  • Pay-by-Bank Checkout: One-click A2A payments across the UK and EU
  • Smart Routing via IPSL: Accelerates settlement by choosing the best-performing payment rails in real time
  • Real-Time Payouts and Refunds: Facilitates instant withdrawals and refunds to verified accounts
  • Recurring Payments Support: Offers recurring mandates and VRP equivalents
  • Multi-Region Coverage: Active in the UK, EU, Australia, Brazil, and expanding

Volt stands out for its focus on performance, reliability, and smart payment orchestration. It’s built for speed and scale, especially where milliseconds and transaction success rates impact business revenue.

When TrueLayer Makes More Sense

TrueLayer is well-suited for businesses that:

  • Require both Open Banking payments and data access in one platform
  • Operate in fintech, lending, or digital onboarding spaces where KYC and account verification are essential
  • Want direct control over VRPs (Variable Recurring Payments) for subscriptions, personal finance tools, or automated transfers
  • Prioritise developer-first APIs with clean documentation, sandbox environments, and broad financial service integrations

TrueLayer’s value lies in its flexibility and deep integration with UK and EU Open Banking frameworks. It’s a good match for businesses that want to build tailored financial flows or combine payments with insights.

When Volt Is the Better Option

Volt is the stronger choice if your business:

  • Is focused on scaling internationally, especially in regions like Brazil or Australia where Volt has active payment coverage
  • Prioritises settlement speed and uptime reliability over additional data or analytics tools
  • Wants access to smart-routing technology to avoid failed or delayed transactions

Volt’s infrastructure is ideal for merchants operating in time-sensitive, cashflow-heavy environments where payment latency can create business risk.

Summary:

  • Choose TrueLayer if your business needs both payments and bank data, or if you’re building a full Open Banking stack.
  • Choose Volt if your priority is speed, reach, and smart network routing, especially for checkout, payouts, or disbursements at scale.

Does Volt offer faster settlement than TrueLayer?

Volt generally offers faster settlement due to its Instant Payment Settlement Layer (IPSL), which uses smart routing to reduce delays. However, both providers typically settle UK payments in under a few minutes.

Can I issue refunds with both providers?

Yes. Both TrueLayer and Volt support refunds. TrueLayer includes it as part of PayDirect, while Volt offers real-time refund capabilities via its payments API.
