Due diligence consulting – supporting decision-making in investments and acquisitions
When investment and divestment decisions involve high stakes, reliable due diligence provides the foundation for trust. Sweco offers due diligence services for companies, investors and financiers who need an independent assessment of project risks, profitability and feasibility. Through the DD process, clients gain a clear understanding of how a project performs financially, technically, in terms of market outlook and regulatory requirements.
Sweco has carried out due diligence assessments for dozens of investment and acquisition projects across the Nordics, and our clients value the clarity of our documentation and the reliability of our analysis. Every due diligence assignment is tailored to the client’s needs – from comprehensive assessments to smaller, agile reviews.

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.
Technical due diligence
We assess the functionality, performance and feasibility of technologies, assets and industrial concepts. Our work often includes reviewing production processes, network connections, energy systems, safety conditions and overall operational maturity.
We also frequently evaluate emerging or pilot‑level technologies that are being scaled from demonstration to full industrial operations. In these assessments, we consider technical feasibility, commercial potential, ESG impacts and the regulatory environment.
Commercial due diligence
We analyse the commercial viability of each case. Commercial DD is closely linked to technical and regulatory factors, as technology performance and regulatory frameworks strongly influence commercial outcomes.
In addition to profitability, we assess future market developments, related risks and their impact on the project’s commercial performance.
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.
Geographical focus
Our primary geographical focus is the Nordic countries, and we also carry out assignments in the Baltic states. Thanks to our international network, we can support clients in other European markets as well. In many due diligence assignments, the assessed assets may be located in several countries—for example across multiple Nordic or Baltic markets.
Due diligence consulting across sectors and asset classes
We work with clients from a wide range of industries, including industrial companies, infrastructure asset owners, financial institutions and lenders, energy project developers and renewable energy companies, real estate investors and developers, as well as private equity investors and funds.
We support various types of transactions, such as acquisitions, divestments, greenfield investments, and opportunities to scale emerging technologies.
Early involvement for better outcomes
We recommend engaging Sweco as early as possible in the transaction preparation phase. Early involvement enables:
- Access to more comprehensive operational and technical information
- More time to validate assumptions and test scenarios
- Better alignment between financial advisors, technical experts, and leadership 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.
