Prima Uno has secured a place on the Project Controls Preferred Partner List supporting the Programme and Project Partners (PPP) at Sellafield framework, marking a significant milestone for the Cumbrian-based, female-owned project controls consultancy.
The appointment is the first time Prima Uno has been formally selected to work within the PPP framework, with its integration partner KBR, which oversees a £7bn, 20-year programme designed to transform major project delivery at the Sellafield site.
Mobilised in 2019, PPP brings together Sellafield Ltd, four delivery partners and an extensive supply chain to safely progress some of the UK’s most critical nuclear infrastructure projects.
Prima Uno has successfully won the first mini-competition under this arrangement awarded February 2026 for the PPP’s Preferred Partners. This piece of work will see Prima Uno people supporting PPP’s major projects.
Managing director Sarah Purdham said the announcement represented an important step in the company’s evolution.
She said: “To secure a place on the Project Controls Preferred Partner List for PPP is incredibly exciting for us.
“This is the first time Prima Uno has been formally appointed to work on the PPP framework, we have been supporting KBR under a PCCS contract where four of Prima Uno’s people work as a fully integrated team with Sellafield Ltd and KBR’s project teams.
” After years of supporting Tier Twos such as Atkins, Amentum, Nuvia, Orano on decommissioning contracts such as DDP, being recognised at this level feels like a natural next step and a rewarding one.”
As a Preferred Partner, Prima Uno will provide project controls, risk management and project management expertise under NEC4 contracts, working collaboratively with PPP stakeholders across multiple major projects.
Sarah added: “2026 is a year of ambition for Prima Uno. With new people, new spaces and new opportunities ahead of us, our appointment to PPP arrives at exactly the right moment. It strengthens our commitment to delivering excellence, supporting UK nuclear infrastructure, and creating opportunities for talent here in West Cumbria.”
Prima Uno said joining the PPP Project Controls Preferred Partner List reinforces the company’s longstanding commitment to high-quality project delivery and the belief that an independent, female-led SME from Cumbria can play a significant role in some of the UK’s most complex and meaningful major projects.
“We’re proud of our roots, proud of our team, and proud to be part of PPP’s mission,” Sarah said. “This appointment reflects who we are; committed, capable and passionate about delivering work that truly matters.”
