Data platforms, real-time operations, modernisation that serves the transition.
Direct working experience with Bryt Energy, Amber Energy, Switch2, ENSEK, and ITP Energised. Cloud-native application development, modern data services, and managed services on AWS. AWS Advanced Consulting Partner with the Energy Competency.
UK energy is in the middle of a structural shift. Renewable supply is growing faster than the systems that account for it. The smart meter rollout is generating data at a tempo most retail platforms were never built to handle.
Settlement is reforming. Grid operators are publishing real-time data that downstream players need to consume and act on. ESG and emissions reporting cycles are tightening. The wholesale price volatility of the last few years hasn’t gone away.
Each of those pressures sits on your data layer. The platforms that ran your business well at lower data volumes and slower tempos now need to do more, faster, with cleaner inputs.
Within Energy, the third-party-intermediary (TPI) sub-vertical (energy procurement, broking, and net-zero advisory) is a named D55 sub-specialism. Our anchor client is Amber Energy, a B Corp TPI in Cardiff, where the work was an event-driven Salesforce-to-payments integration on AWS using EventBridge and Lambda. If you’re a TPI, that’s the closest comparison we’ll bring to your conversation.
Overnight batch reporting cycles that no longer match a business operating on real-time wholesale prices and half-hourly settlement.
Self-service portals, live consumption views, account changes processed without overnight delay. The customer expectation has moved past what most retail energy platforms were built to deliver.
Grid operator feeds, smart meter data, weather APIs, third-party services for tariff optimisation. Each integration is a small project that adds to your operational tail.
The same numbers used in your commercial decisions need to stand up in regulatory and investor reporting.

Your data layer is where the gain comes from. Get the data right and the rest of the capability stack becomes possible: real-time operational visibility, customer-facing services that match consumer expectations, ESG reporting that lands clean, AI and analytics that produce decisions your business will trust.
Real-time, event-driven architecture is the default shape for energy work. The half-hourly settlement world doesn’t fit overnight batch; event-driven AWS architectures on services like EventBridge, Step Functions, and Lambda are the right shape for the work.
The Funded Data Strategy Diagnostic, one structured morning with your leadership team financed directly by D55, is the standard low-friction entry for a data conversation. Anchored on Mindset, People, Process, and Technology, it surfaces your priorities across the four dimensions in parallel and ends with a clear next-conversation decision.

Single source of truth on AWS for the customer, consumption, generation, and operational data your business runs on. Built so the platform can carry your next phase (analytics, AI, customer-facing data services) rather than just tidy up today’s reporting.

Re-architecture of your legacy batch platforms into asynchronous, event-driven services on AWS. The pattern fits retail energy suppliers, heat network operators, generation businesses, and TPIs whose data tempo has outpaced the original architecture.

Salesforce, billing platforms, payments stacks, and operational systems brought together into a unified data layer. Real-time integration via EventBridge and Lambda where your use case calls for it; batched where it doesn’t.

Joint build models where your team finishes the engagement equipped to own and evolve the platform. The Switch2 engagement is the clearest example: we worked alongside Switch2’s in-house developers throughout the legacy-to-AWS modernisation, and the Switch2 team finished with modern cloud skills and a platform they control.
Your first conversation usually identifies one of three doors: a Funded Data Strategy Diagnostic when your data and AI plan isn’t yet settled, an AWS-funded migration assessment when the work is platform replacement or modernisation, or a paid scoping engagement when the work is well-defined.
Engagement cadence fits the sector. Your quarterly business reviews are anchored on your commercial and operational metrics. Skills transfer continues into the managed engagement. The regulatory context for your sector is built into the way we make recommendations.

A 100 per cent renewable commercial supplier. Consolidated a fragmented SaaS estate into a central data platform on AWS, with intelligent data pipelines on AWS Step Functions and Lambda feeding a single data lake.
A B Corp TPI in Cardiff. Replaced a manual integration between Salesforce and its payments stack with a real-time, event-driven bridge on AWS EventBridge and Lambda.
The UK’s most experienced provider of end-to-end heat network solutions. Modernised a legacy on-premises estate to AWS as a joint build with the in-house team. The core platform was re-architected from overnight batch into asynchronous, event-driven services on Amazon ECS.
A leading provider of utilities billing and customer management technology. Worked with D55 on application development.
