Case
Powering faster, fairer energy switching for consumers and business.
As the market moved to faster switching, a national operator needed technology that could keep pace — reliable data, real-time checks, and confidence for regulators and suppliers alike. Ju Group built the platform and programme delivery to make next-day switching achievable at scale.
- One market data layer replacing fragmented legacy interfaces
- Real-time switching validation with a full audit trail
- Leadership dashboards for assurance, incidents, and market health
The challenge
Consumers and businesses expected to change supplier quickly and fairly. Behind the scenes, batch processes, mismatched identifiers, and brittle point-to-point links made every release risky — and every error visible in complaints data.
The operator had to reform market systems while the market kept running. That meant a partner who combines platform engineering with programme governance and who understands regulatory scrutiny when billing and supply are involved.
Success required proof that switching would work first time — for participants, the regulator, and millions of end customers — not a big-bang cutover with hope as the fallback plan.

The solution
Ju Group delivered a cloud-native market data platform: canonical identifiers, event-driven validation, and self-service onboarding so suppliers could connect in weeks, not months.
Parallel running, automated reconciliation, and integration factories de-risked cutover weekends. Executive teams gained live visibility across the market graph — not end-of-week reports assembled by hand.
The result
Next-day switching went live on schedule. Switching-related complaints fell in the first quarter, and participants could trace and fix exceptions in minutes instead of days.
Auditors received a clear line from policy intent to production behaviour. The platform is now the spine for switching, settlement support, and the analytics that keep the market fair.
“We needed a partner who could hold the line on quality while the pace of reform accelerated. Ju Group never treated this as a technology project alone — it was a market outcome we had to land together.”
Ju Group continues to run the platform engineering function and extend the same patterns to adjacent market data products — so reform programmes reuse proven capability instead of starting from scratch.
For the operator, the investment is a strategic asset: faster switching for customers, lower integration cost for participants, and assurance evidence available when regulators ask — not weeks later.
Ju Group gave the market, regulators, and participants confidence that faster switching would work first time — and kept that promise through delivery and go-live.
