International energy consultancy Penspen has underlined its long-term commitment to the north-east of Scotland by opening a new office in Aberdeen. The move to Balmoral Business Park in Altens marks a major milestone in the company’s regional growth and brings together the expertise of Penspen and C&I Engineering Solutions, which it acquired in October 2024.

The new office at Building One, three miles south of the city centre, provides a modern, well-connected base for more than 200 specialist engineers. It supports Penspen’s growing pipeline of energy security and energy transition projects, while also creating space for future expansion.
From the new base, Penspen’s team in the north-east will deliver several flagship projects, including:
- The detailed engineering scope for the HyNet CO₂ transportation pipeline in Liverpool Bay.
- Hydrogen gap analysis for the Trans Adriatic Pipeline, part of the EU’s Southern Gas Corridor.
These projects reflect Penspen’s dual focus on energy security and infrastructure repurposing to support hydrogen and CO₂ integration — a strategic priority for many of its global clients.
Darren Bartlett, Director of Engineering and Energy Transition at Penspen, said: “Aberdeen is a critical hub for us — a region where we have deep roots and long-standing relationships with key clients. This move reflects both our history in the north-east and our ongoing commitment to its future.
“Bringing the Penspen and C&I Engineering Solutions teams together under one purpose-built roof will strengthen collaboration and further enhance the service we deliver to our clients.”
The Altens site will also support delivery of Penspen’s new training courses on repurposing infrastructure for hydrogen, as well as CO₂ capture and transmission — key areas of focus as the UK positions itself at the heart of the energy transition.
“This new base provides a sustainable and flexible working environment that supports innovation and growth. We’re proud to be investing in Aberdeen at a time when high-quality engineering is vital to delivering secure, low-carbon energy systems.”, Bartlett added.
Milestone Moment for Growing Engineering Consultancy
While C&I Engineering Solutions had been based in Balmoral Business Park since 2019, this relocation into a larger, shared facility marks a significant step forward for London-headquartered Penspen.
Penspen has relocated from its long-standing base at Queen’s Gardens, where it had operated from in Aberdeen since 2019.
Operating for over 70 years, the global organisation has delivered more than 15,000 projects across 100+ countries, including major developments in the Middle East, Africa, Asia, Europe, and North America. The company’s presence in Aberdeen dates back to the late 1980s, and its workforce has grown steadily — from around 750 people globally in 2019 to more than 1,200 specialists today, including over 200 engineers based in Aberdeen.
“It’s an exciting period for Penspen as the demand for quality engineering solutions ramps up to support not only energy security, but the design of both new facilities and the repurposing of critical infrastructure to support hydrogen and CO2 integration,” said Bartlett.
“Investing in our Aberdeen presence enables us to grow our team and our capabilities to deliver technically challenging projects that support global clients at every stage of the energy project lifecycle.
“We’re proud to make a commitment to the city as it positions itself at the heart of the energy transition.”
- Penspen’s Aberdeen-based energy transition courses take place on 17-18 June (Repurposing Pipelines for Hydrogen) and 24-25 June (CO2 Capture and Transmission).
