Problems solved, start to finish.

The challenge

OneSelect was a five-person energy supplier with no real IT foundation. They were set to grow fast and needed infrastructure that could scale with them, built right the first time rather than rebuilt every few months.

What we did

We designed and delivered the entire environment from a blank slate, starting at the network: the first switch and a firewall configured for high availability, so a single failure couldn't take the business offline.

On top of that we provisioned their first on-premises Windows server with structured file shares and permissions, migrated mailboxes to Microsoft 365, deployed VoIP telephony and set up encrypted cloud backup to AWS.

The outcome

The business grew from five people to sixty on the same foundation. Because resilience and backup were designed in from day one, OneSelect kept adding people and capability without tearing anything up.

The challenge

EnergieFlex, a Dutch energy company and the parent behind OneSelect's UK launch, needed a partner to take over its existing IT estate and bring it under tighter, more resilient management as the group expanded into the UK.

What we did

We took ownership of the environment and relocated their on-premises servers from the Netherlands to the UK.

We then provisioned site-to-site VPN links so the Dutch and UK operations ran as one secure, connected network rather than two islands, and took on day-to-day support across the group.

The outcome

One unified, resilient IT backbone spanning two countries, supporting more than 250 users, with consistent infrastructure, secure connectivity between sites and a single team that understood the whole estate.

The challenge

When more than 30,000 customers were moving from OneSelect to BrilliantEnergy, the billing behind every account had to be reviewed and validated before handover. The volume and detail were beyond what off-the-shelf tools could handle cleanly.

What we did

We built a bespoke application to review billing across every account, surfacing discrepancies and giving a clear, accurate picture of each customer ahead of the transfer.

The outcome

A high-volume, error-prone migration became a controlled, auditable process. It shows a different side of what we do: custom software built to solve a specific business problem at scale.
