Due diligence consulting services
Due diligence consulting services
When investment decisions carry high stakes, reliable due diligence becomes the foundation for confidence. Across all due-diligence streams, Sweco’s multidisciplinary experts support both sellers and buyers by uncovering the true technical, commercial, ESG, and regulatory realities behind every asset and transaction.
We support both buy-side and sell-side clients across all due-diligence streams.
Technical due diligence
We assess the functionality, performance and feasibility of technologies, assets and industrial concepts. Our work often includes reviewing production processes, grid connections, energy systems, safety conditions and overall operational maturity.
We also frequently assess emerging or pilot-scale technologies that are being scaled from demonstration level to industrial-scale facilities, including evaluating their technical feasibility, commercial potential, ESG implications and regulatory conditions.
Commercial due diligence
We analyze the commercial viability of each case. Commercial DD is often closely linked to the technical and regulatory streams, since technology performance and regulatory frameworks strongly influence commercial outcomes.
ESG due diligence
ESG aspects are increasingly central to investment decisions and long-term value creation opportunities. We review sustainability performance and governance processes, social sustainability aspects such as health, safety, labor and human rights, regulatory compliance, environmental impacts, and sustainability risks and opportunities.
In addition, our ESG assessments can include explicit alignment checks against key EU frameworks such as the EU taxonomy, the do no significant harm (DNSH) criteria and relevant SFDR sustainable investment requirements. ESG due diligence assessment topics are always customized based on material topics for the transaction in question.
Regulatory due diligence
For highly regulated industries, such as energy networks, regulation plays a defining role in value creation. Sweco’s regulatory consultants assess current and upcoming frameworks, compliance requirements and the implications for commercial and technical feasibility.
Depending on the case, regulatory DD may be integrated with commercial DD or form its own separate workstream, particularly in monopoly-type businesses where the regulatory model is a core value driver.
Our primary geographical focus is the Nordic region, with assignments also carried out in the Baltics. Our international network enables us to support clients also in other European countries. Assets assessed in a single DD assignment may be in multiple countries, for example across several Nordic or Baltic markets.
DD consulting across multiple sectors and transaction types
We work with clients from a wide range of sectors, including:
• Industrial operators
• Infrastructure asset owners
• Financial institutions and lenders
• Energy developers and renewable energy companies
• Real estate investors and developers
• Investors scaling new or emerging technologies
• Funds that raise capital from multiple investors to acquire or develop assets
• Clients seeking suitable acquisition targets before entering the DD phase
We support different transaction types, such as:
• Acquisitions
• Divestments
• New-build investments
• Technology scale-ups
• Investment rounds
• Portfolio-level analysis
Our due diligence services are available for both buyers and sellers and may also be required by lenders as part of the financing process.
Early engagement for better outcomes
We recommend involving Sweco as early as possible in the transaction pipeline. Early engagement allows:
• Access to more complete operational and technical data
• More room to verify assumptions and test scenarios
• Better alignment between financial advisors, technical specialists and management teams
Our approach to due diligence
Our due diligence assignments are typically compact 2–4-week processes:
1. Kick-off & scoping: Understanding the asset, business model, technology and client priorities.
In addition to DD carried out during ongoing transactions, Sweco can also support earlier phases, such as identifying suitable acquisition targets or conducting preliminary market assessments.
2. Data room review: Analysing documentation provided by our client and identifying gaps.
3. Open source & market research: Complementing data room material with independent research.
4. Q&A & stakeholder interviews: Clarifying open questions, validating assumptions and exploring risks.
5. Site visits (optional): When relevant, on-site inspections help confirm safety conditions, technical performance or physical risk factors.
6. Findings & reporting: Delivering a decision-ready DD report or presentation that highlights the issues most likely to influence valuation, schedule, permitting or operability.
We can also support clients in the next steps after the due diligence phase, such as implementing recommended mitigation or optimisation measures, preparing documentation or verifying the feasibility of identified improvements.
Why choose Sweco for due diligence consulting?
Multidisciplinary expertise, one integrated DD team
Sweco brings together specialists from across our organisation, forming tailored teams with exactly the expertise each case needs. This means the same team can examine technical performance, regulatory implications and commercial consequences in one coordinated process.
End-to-end capability
Beyond reporting risks, we help clients understand what they mean in practice, whether it concerns energy efficiency, process reliability, grid capacity, permitting or ESG compliance. We can also support the implementation of recommended improvements.
Cross-market experience
Our Nordic and European network enables us to execute DD assignments across borders. Assets do not need to be in a single country; we routinely assess portfolios spanning multiple Nordic or Baltic regions.
Holistic view of value creation
Technical and commercial perspectives are deeply intertwined. We prioritise the issues that influence EBITDA, capex, OPEX, regulatory incentives or operational resilience.
