Still Struggling with Utility Billing? These 6 Platforms Solve It in 2025

Utility billing is undergoing a rapid transformation in 2025 as providers face mounting pressure to modernise. With the rollout of smart meters and increased regulatory focus on billing accuracy, traditional systems are being replaced by automated platforms designed to enhance transparency and customer trust.

According to Ofgem, over 33 million smart and advanced meters have been installed across homes and small businesses in Great Britain as of early 2025. This shift is driving a parallel demand for billing platforms that can process real-time usage data, issue timely invoices, and support flexible tariff models.

But billing is only half the story.

What’s often missing is a streamlined way to actually collect payments, reconcile transactions, and avoid costly delays, especially for providers with large customer bases or complex disbursement models.

How Finexer Can Support Your Utility Billing Stack

Most utility billing software focuses on invoicing, metering, and compliance, but collecting payments and reconciling them quickly is often still a challenge.

That’s where Finexer comes in.

Finexer provides a suite of UK-focused Open Banking APIs that utility companies can integrate alongside their existing billing platform to improve the full meter-to-cash process.

That’s why in this guide, we’re not just covering the 6 best utility billing platforms, but also showing how modern providers are combining these systems with Open Banking-based Payments APIs like Finexer to automate the full meter-to-cash process.

1. Get Paid in Real Time

Instant Request to Pay (RTP): Collect payments directly from customer bank accounts within minutes. No card fees, no waiting periods.

2. Bill with Confidence

Balance Check Before Billing: Avoid failed collections by verifying customer account balances before charging. Reduce friction and reprocessing.

3. Reconcile Instantly

Real-Time Payment Reconciliation: Automatically match incoming payments with billing records using transaction data no manual work required.

4. Scale with Smart Recurring Payments

Flexible VRPs (Variable Recurring Payments): Enable recurring payments that adjust to actual usage, ideal for services like water, electricity, or heating.

5. Keep Costs Predictable

Affordable and Transparent Pricing: No setup fees. No cancellation penalties. Just flat, usage-based pricing that scales with your billing needs, helping UK utility firms save up to 90% on transaction costs compared to traditional card-based systems.

Finexer doesn’t replace your billing system; it enhances it.

If you’re managing high-volume payments or want better control over cash flow and transaction costs, Finexer can be added as a flexible, API-first payments layer tailored for UK utility providers.

“Our business isn’t about the volume of consents—it’s about delivering high-quality services to some of the biggest names in the industry. We needed a partner who understood the importance of providing business-focused solutions, and Finexer joined us on that journey.”
