Key Open Banking Pricing Models Explained

In 2025, the UK’s Open Banking landscape offers a variety of pricing models tailored to diverse business requirements. Understanding these models is crucial for selecting a provider that aligns with your operational and financial goals.

1. Flat Fee per Transaction

Overview:
A straightforward model where a fixed fee is charged for each transaction, regardless of its value.

Typical Rates:
Between £0.20 and £0.30 per transaction.​

Ideal For:
Businesses with predictable transaction volumes seeking simplicity and ease in budgeting.​

Considerations:
While this model offers predictability, it may not be cost-effective for high-volume or high-value transactions.​

2. Percentage-Based Fees

Overview:
Charges are calculated as a percentage of the transaction amount.

Typical Rates:
Ranging from 0.1% to 0.5% per transaction.​

Ideal For:
Businesses with lower transaction values, such as micro-payment platforms.​

Considerations:
Costs can escalate with higher transaction values, potentially impacting profitability.​

3. Tiered Volume Discounts

Overview:
Pricing decreases as transaction volumes increase, incentivising higher usage.

Example Structure:

• First 1,000 transactions: £0.25 each
• 1,001–5,000 transactions: £0.20 each
• 5,001+ transactions: £0.15 each​

Ideal For:
Scaling businesses anticipating growth in transaction volumes.​

Considerations:
Requires careful forecasting to ensure cost benefits are realised.​

4. Monthly Minimum Commitments

Overview:
A minimum monthly fee is charged, regardless of usage.

Typical Rates:
Starting from £100 per month, varying by provider and service level.​

Ideal For:
Established businesses with consistent transaction volumes.​

Considerations:
May not be suitable for startups or businesses with fluctuating transaction volumes.​

5. Freemium and Sandbox Access

Overview:
Providers offer free access to a sandbox environment for testing and development.

Ideal For:
Startups and developers seeking to evaluate services before committing financially.​

Considerations:
Some providers may limit the duration or features available in the free tier.​

What Drives Open Banking Costs?

Not all Open Banking pricing models are created equal. Beyond just the transaction fee, several behind-the-scenes factors influence what you’ll actually pay and whether the provider’s pricing is sustainable for your business in the long run.

Here are the main cost drivers behind Open Banking pricing in the UK:

1. Type of Service: Payments vs Data

• PISP (Payment Initiation Service Providers) offer account-to-account payments. These often come with variable fees depending on the transaction volume, value, or added features like bulk payouts or branded checkouts.
• AIS (Account Information Services) provides access to financial data such as balances, transaction history, and categorised merchant data. Data-only services may appear cheaper, but costs can rise if you need real-time access, enrichment, or aggregation.

Some providers offer both services under a single platform, bundling pricing; others separate them, so you’ll need to budget accordingly.

2. UK Bank Coverage and Availability

Providers that connect to 99% of UK banks, including both high street and challenger banks, generally offer more value. However, building and maintaining these connections (especially with real-time data) can increase infrastructure costs, which often trickle down into the final pricing.

Important note: Some EU-based providers operating in the UK may offer limited UK coverage, which can mean fewer supported customer accounts and additional integration gaps.

3. Developer Experience & Integration Style

Your costs don’t just come from the provider’s invoice — they also show up in your development time. Some providers offer:

• Full APIs with clear docs (ideal for in-house teams)
• Low-code or no-code tools (faster to deploy but may come at a premium)
• SDKs, plugins, or white-label components (good for platforms but sometimes locked behind higher pricing tiers)

The smoother the integration, the less you’ll spend on setup, debugging, or workarounds.

4. Compliance & Regulatory Infrastructure

UK providers must comply with the Financial Conduct Authority (FCA) and PSD2 regulations. Some also undergo ISO 27001 or SOC 2 audits to meet enterprise-grade data security standards. These certifications come with costs, and the more rigorous the infrastructure, the higher the provider’s baseline operating expenses.

That said, you benefit from this too: it reduces your own compliance burden.

5. Add-on Features and Customisation

Expect additional costs for:

• White-label support (your branding on flows and dashboards)
• VRP (Variable Recurring Payments) support for advanced recurring payments
• Fraud prevention tools (e.g., account risk scoring, transaction analysis)
• Advanced data enrichment (e.g., categorising merchants, income verification)

Not every business needs all of these, but if you do, make sure they’re not billed as expensive add-ons after you’ve signed up.

Choosing an Open Banking Provider Based on Your Business Type

The right Open Banking provider isn’t just the one with the lowest rates — it’s the one whose pricing model fits your use case, usage pattern, and technical setup. What works for a fast-scaling platform may be inefficient for an accounting firm managing recurring client transactions.

Below is a breakdown of what to consider based on the nature of your business.

1. Startups and Early-Stage Platforms

Startups often need room to test, build, and pivot, without incurring high fixed costs. When evaluating Open Banking pricing, look for:

• No monthly minimums: Avoid platforms that charge base fees regardless of usage.
• Transparent, usage-based pricing: Predictable and scalable as transaction volumes increase.
• Full-featured sandbox access: Critical for internal testing and early-stage product development.
• Simple API documentation or no-code options: To reduce reliance on heavy engineering teams.

Finexer, for example, allows startups to integrate core payment and data features without upfront cost pressure or usage thresholds.

2. Accounting and Bookkeeping Firms

For accounting firms, pricing predictability and data access quality are paramount. Look for:

• Real-time AIS capabilities: To retrieve categorised transaction and balance data across client banks.
• Flat or low-cost usage pricing: Suited to recurring workflows such as reconciliations or affordability checks.
• No bundled fees for unused services: If your firm doesn’t need payment flows, avoid platforms that require joint AIS + PISP commitments.
• White-label options (optional): Useful for firms offering branded portals or dashboards.

Finexer’s model supports firm-level use cases without imposing payment processing overheads if they’re not needed.

3.SaaS and Client Platforms

If you’re building a platform that embeds finance or payments, such as a payroll, lending, or procurement tool, you’ll want pricing models that:

• Scale with transaction volume
• Include optional VRP and bulk payout features
• Support white-labelling for client-facing flows
• Avoid expensive licensing tied to user seats or platform fees

A provider that bundles pricing with flexibility for branding and custom flows is typically more cost-efficient over time.

4. Enterprise or High-Volume Use Cases

For regulated firms or high-throughput platforms:

• Tiered volume discounts become essential.
• Custom SLA and compliance support may factor into pricing.
• Access to dedicated integration support can justify higher rates if it reduces operational risks.

Here, custom-quoted platforms may offer better flexibility, but be sure to clarify minimum commitments and renewal terms.

Bottom Line:
Pricing should align with how and when you plan to use Open Banking. Whether your business needs 100 calls per month or 100,000, the right provider will offer clarity, scale, and pricing that doesn’t penalise you for growing at your own pace.
