We aredifferent We are Sigma Connected

As an outsourcing partner, we provide customer experience solutions, but at Sigma Connected, we do things a little differently.

We are Sigma Connected,
we are different

Different is thousands of independent thinkers, connected and working together. Different is flexible, scalable, smart. Different listens so different learns; that’s why different understands. Different says ‘can do’ and then it does. Different is never settling for ‘good’ as good enough. Different is brave. Different is kind. Different is better.

We are not just another business process outsourcing provider. We are a people company, built on the power of human connections. Whether that’s with our employees, our clients, our clients’ customers or our wider communities, to us every connection is important. Because better connections mean better outcomes for all.

Celebrating 15 years of difference

2026 marks a defining moment for Sigma Connected as we celebrate 15 years of growth, partnership, and progress.

Take a look at our journey
  • What started as a small business has grown into an organisation of over 5,000 people, supporting clients across different sectors and geographies.

    From the beginning, we have taken a different approach – building our business around long-term partnerships, deep sector expertise, and a clear focus on delivering the right outcomes for our clients and their customers.

  • This milestone reflects more than scale. It reflects how we have chosen to operate.

    As customer interactions have become more complex, sensitive, and often regulated, we have focused on the moments that matter most – where empathy, judgement, and expertise make the difference.

    Our approach has remained consistent: stay close to our clients, understand their challenges, and deliver in a way that is practical, resilient, and built to last.

  • Fifteen years in, we are proud of what we have built and the partnerships that have shaped us.

    Being different has never been about standing apart for the sake of it – it is about doing the right things, in the right way, for the right reasons. That focus continues to guide us as we look ahead to what comes next.

“World class collections started with a simple belief. Every customer deserves genuine care, real effort and the strongest possible support, especially those who need it most. Our ambition was to make that instinctive, a culture rather than a checklist. Sigma Connected shared that vision from day one and brought the passion to make it real on every call.”

Matt Court
Head of Customer Operations, Oakbrook.

“We know that when our residents struggle to pay their council tax, it’s rarely a standalone issue. It’s often linked to wider financial pressures, and without early support, debt can quickly escalate.

ReachOut gave us a trusted, non-judgemental way to re-engage residents who had stopped responding, helping them reconnect with council support and begin addressing their arrears. Many also discovered they were entitled to additional financial help – in some cases nearly £800 a month – making a huge difference to their situation.”

Nick Houlton
Finance Manager: Revenues & Benefits, Barnet Council

The past 12 months have seen us achieve incredible success. It’s been amazing to watch everyone work in such a collaborative environment and to see a partner truly listen to their agents and implement the necessary improvements.”

Sammy Cocker
Head of Outsource Operations at Shell Energy

“The strongest partnerships are built on trust, openness and a shared purpose. Together with Sigma Connected, we empowered our people to deliver the very best outcome for every customer. That’s what genuine partnership looks like.”

Chelsie Mead
Operations Relationships Manager, Oakbrook.

“ReachOut have enabled us to start conversations with residents that we had previously been unable to liaise with. This has enabled us to offer further support to more low-income households using the support and advice available to us.”

Andrew Hatcher
Revenues and Benefits Lead Specialist, Folkestone & Hythe District Council
