This growth, achieved despite challenging market conditions, reflects the Aberdeen-headquartered firm’s ability to deliver value across the energy sector.

Key project successes include a multi-million-pound front-end engineering design (FEED) contract from NEO Energy for the Greater Buchan Area redevelopment, and a project management consultancy (PMC) contract exceeding £10m for INEOS E&P’s Hejre Project.

Apollo also secured several low-carbon and industrial decarbonisation projects, including studies for gigawatt-scale floating offshore windfarms (FOW) and a hydrogen project in North Wales. Notably, 48% of the company’s revenue now comes from outside the oil and gas sector.

To capitalise on the evolving energy landscape, Apollo has reorganised its business into three core areas: Oil and Gas, Decarbonisation, and Marine Energies. This strategic shift enhances the firm’s ability to deliver focused expertise and align with industry priorities. Complementing this reorganisation is the launch of Apollo’s advisory business, offering strategic guidance on energy transition and ESG.

Apollo managing director Richard Bell said: “This year has been defined by growth, focus, and delivering exceptional results for our clients.”

He added: “As we enter 2025, I am delighted to report we are on track for a further year of growth, and we anticipate an increase in revenues of around 25% for this financial year.

“While engineering, consultancy and advisory services make up most of our revenue, our services in PMC, assurance and technical placements continue to grow, and our Apollo KnowHow platform, a proven software tool for asset integrity management, is being readied for deployment in new markets such as offshore wind.

“While 2025 will undoubtedly continue to have its challenges, we have an enviable track record and diversified portfolio across markets and regions.”
