Supporting a strategic transition into offshore wind
At a glance
When Maven invested in GEV Group, the business had identified an opportunity to apply its specialist offshore access expertise to the rapidly growing wind energy sector. Supporting a management buyout, Maven provided the capital and strategic support required to accelerate diversification into renewables, expand internationally and strengthen the Group's market position. Over the course of the investment, revenues increased four-fold to almost £16 million, culminating in a successful exit to Bridges Fund Management that generated a 2.7x return for Maven investors.

Recognising a opportunity in offshore wind
GEV Group was originally established as a specialist engineering and access services provider to the North Sea Oil & Gas sector. Through its expertise in rope access and specialist manpower services, the business had built a strong reputation for delivering complex projects in challenging offshore environments.
As investment in renewable energy accelerated across the UK and Europe, management identified a significant opportunity emerging alongside the growth of offshore wind. Increasing numbers of turbines were being deployed offshore, creating a growing requirement for specialist maintenance services capable of supporting the long-term performance and reliability of these assets
For GEV, the opportunity was particularly compelling. Many of the skills and operational capabilities developed serving the Oil & Gas sector were directly transferable to wind turbine blade inspection and repair. The business was well positioned to leverage its existing expertise to enter a rapidly expanding market with strong long-term growth fundamentals.
However, capital would be required to support the transition. Management needed to invest in developing a dedicated renewables capability while maintaining the strength of its existing operations and creating an ownership structure aligned with future growth ambitions.
Investing behind a strategic diversification
Maven invested to support the management buyout of GEV Group, backing CEO David Fletcher and the wider management team as they pursued a strategy to diversify into renewable energy and accelerate growth.
The transaction enabled two legacy shareholders to exit the business while creating an equity participation structure designed to incentivise senior management and support long-term value creation.
For Maven, the investment represented an opportunity to back an experienced team with a clear vision for the future of the business. The combination of established technical expertise, a strong market reputation and exposure to a rapidly growing end market created a compelling platform for growth.
"GEV had developed a highly respected position within the energy services sector and possessed a skillset that was directly applicable to the growing offshore wind market,” says Andrew Ferguson, Partner at Maven. “We saw an opportunity to support management as they executed a strategy that could significantly expand the scale, reach and value of the business."
Reflecting on the investment, CEO David Fletcher adds "At that point, GEV needed development capital, but we also needed to address shareholder issues and ensure the business had the right capital structure and incentives to attract the talent required to drive growth into new markets."
Leveraging existing capabilities to enter a high-growth market
Following investment, management accelerated the development of GEV Wind, establishing a dedicated division focused on field rotor blade maintenance services.
Rather than building an entirely new business model, GEV's strategy centred on applying capabilities it had already developed within the offshore energy sector. Its expertise in rope access, offshore operations and technical field services provided a strong foundation from which to develop specialist blade maintenance capabilities and build credibility with wind farm operators.
As offshore wind deployment increased, demand for maintenance and repair services grew alongside it. GEV successfully established itself within the market, securing contracts and building a reputation as a trusted partner to operators seeking to maximise turbine performance and minimise downtime.
The business's ability to transfer knowledge and expertise from one energy sector to another enabled it to scale efficiently while creating a differentiated market position. What began as a strategic diversification initiative evolved into a significant driver of growth, helping reposition the business around one of the fastest-growing segments of the global energy market.
Expanding internationally to strengthen the platform
Alongside diversification, international expansion formed a key pillar of GEV's growth strategy.
Management recognised that establishing a presence outside Europe would provide access to a broader customer base while helping to mitigate seasonal fluctuations in demand caused by adverse winter weather conditions, which can restrict maintenance activity across European wind farms.
Working closely with management, Maven supported the strategic decision to expand into North America. The move not only increased the size of the addressable market but also created opportunities to generate more consistent revenues throughout the year.
The business quickly gained traction in the US, securing important contracts and establishing an operational foothold that would become an increasingly important contributor to growth.
"The timing of Maven's investment, as well as the strategic support they provided, enabled us to develop and successfully implement an international growth strategy,” says David. “This gave us a significant head start over competitors and helped de-risk our geographical exposure."
By combining sector diversification with geographic expansion, GEV was able to build a more resilient and scalable platform capable of supporting long-term growth.
Creating value through partnership
Throughout the investment period, Maven worked closely with management as an active and supportive partner.
Alongside providing growth capital, Maven offered strategic guidance and practical support as the business navigated a period of significant transformation. As opportunities emerged, additional co-investment funding was secured to ensure management could continue executing its growth plans without compromising momentum.
The relationship was characterised by open communication, constructive challenge and a shared focus on long-term value creation.
"When we engaged with Maven, we had a number of clear financial goals and growth milestones,” explains David. “Growth rarely follows a straight line, but we succeeded by forging a positive and effective working relationship. Maven's experience and ability to support the business through both opportunities and challenges played an important role in helping us achieve our objectives."
Over the course of Maven's investment, revenues increased four-fold, reaching almost £16 million as the business continued to strengthen its position within the global wind energy market.

Accelerating growth for British business
The successful execution of GEV's strategy attracted significant interest from both strategic and financial buyers.
By the time of Maven's exit, the business had transformed from a specialist North Sea energy services provider into a recognised global leader in field rotor blade maintenance services, with a growing international footprint and an increasingly focused position within the renewable energy sector.
Following a competitive process led by KPMG, Maven realised its investment through the sale of GEV Group to Bridges Fund Management less than four years after the original management buyout.
The transaction generated a 2.7x return for Maven investors and marked the beginning of the next stage in the company's growth journey.
"The growth achieved by GEV following the buyout was testament to the quality of the management team and the strength of the strategy they executed,” says Andrew. “We are proud to have supported the business as it diversified into renewables, expanded internationally and established a market-leading position in a sector benefiting from powerful long-term growth drivers."
Today, GEV's evolution demonstrates how strategic diversification, international expansion and strong management execution can create significant value. By identifying an emerging market opportunity and leveraging existing capabilities to capture it, the business successfully repositioned itself at the forefront of the global offshore wind industry.
