Maximising funding, tax relief and profitability as you deliver low‑carbon projects
The UK energy and renewables sector is growing fast, with ambitions of up to 70GW of solar by 2035 and around 400,000 additional clean energy jobs by 2030. With opportunity comes complexity: grid connection delays and queue reform, planning and regulation, rising costs, intricate tax incentives, and accessing the right funding. We help energy and renewables businesses unlock every pound of available support while building sustainable, profitable operations.
Whether you’re investing in your own installation or working in the supply chain, we help you access funding, control costs and optimise tax so projects stack up and cash flow is protected.
We work with wind, solar, new technologies, energy generation and storage, site developers and supply chain providers.
Whether your projects sit within solar, hydro, wind, battery or the wider nuclear supply chain, we support set up and funding, financial reporting, tax reliefs and valuations.
We’ve secured successful R&D tax relief claims, ensured tax deductions on project sales, and delivered significant tax savings across wind, hydro and battery projects - turning complex rules into clear financial outcomes.
Memberships
We are active members of Scottish Renewables and BECBC, staying close to developments as the clean‑energy and technology sectors evolve.

We reached out to Armstrong Watson to do a first-year audit following a large investment in our business. They got to work straight away and quickly made themselves indispensable to the business. The audit team have been excellent to work with and highly responsive to the needs of a fast-growing business in an emerging market. We see Armstrong Watson as key partners on the growth journey of our business.

Aegis Energy
At Greenbackers Investment Capital, we operate exclusively within the renewable energy sector, supporting businesses at every stage of their growth journey. Our community ranges from early-stage startups and scale-ups raising several hundred thousand pounds from friends, family and angel investors—often under SEIS and EIS schemes—to more established companies seeking £20 million or more from venture capital and institutional investors.
Across this broad spectrum, one requirement is constant: access to agile, commercially astute advisers who understand both the technical and financial complexities of growth. Mark and his team consistently deliver exactly what these ambitious businesses need.
Their responsiveness, depth of expertise and practical understanding of funding structures provide real confidence to founders and investors alike. In addition, the strength of Armstrong Watson’s wider international network brings further strategic value, particularly for companies with global ambitions.
The support Mark and his colleagues provide plays an important role in underpinning the prospects of these businesses becoming the renewable energy success stories of tomorrow.
I would have no hesitation in recommending Mark McRae and Armstrong Watson to any growth-focused business seeking high-quality, forward-thinking advisory support.
