How Impact House can help
At Impact House, we strongly believe that value chain due diligence is a strategic tool. We support companies in identifying and addressing negative human rights and environmental impacts together with their supply chain partners, enabling them to strengthen competitive positioning, realise long-term cost savings, and build future‑proof value chains.
Our approach is grounded in internationally recognised frameworks, in particular the OECD Guidelines for Multinational Enterprises and the UN Guiding Principles on Business and Human Rights (UNGPs). These principles form the foundation of value chain due diligence and guide how we work with our clients.
Rather than a one‑size‑fits‑all or box‑ticking exercise, we help organisations translate these frameworks into practical, proportionate actions that genuinely fit their business context. No paper tiger—but a flexible, iterative process focused on real-world impact and decision‑making.
From ambition to action
Whether your organisation is just starting out or already well advanced, we support organisations step-by-step throughout their value chain due diligence journey. Our approach combines a clear long‑term roadmap with practical experience and tangible results in the short term (“the practice round”), allowing companies to build maturity over time while already delivering concrete value.
This results in:
- A clear governance structure for ESG in the value chain
- Insight into important risks and negative impacts across the value chain
- Due diligence processes aligned with the OECD Guidelines and UNGPs
- Support through learning by doing, with concrete outcomes
- Active ownership and engagement across relevant internal departments
- Accountability and documentation in line with legal and regulatory obligations
By combining impact and ESG expertise, up-to-date regulatory know-how, and a strong understanding of business realities, Impact House can help you turn value chain due diligence from a perceived burden into a practical system and a source of resilience, trust, and long‑term value creation.

Benefits of partnering with Grant Thornton Impact House
Relevant experience & expertise
We have a pool of experts with direct and relevant expertise on value chain due diligence. Both from a topical perspective (experts on human rights, labour rights, environmental topics, and governance); and a technical and legislative perspective (determining your liabilities and responsibilities and how to prepare for specific regulations). Our experience is demonstrated through our work with a large variety of clients with extensive and complex value chains.
A holistic, practical approach
We combine the business angle (a company’s organisational risks, leverage, and internal stakeholder drives and needs) with the impact angle (the responsibility of the organization towards the affected stakeholders throughout its full value chain).
Tooling agnostic
Rather than working with preferred products, we help organisations work with the tooling they already have, or help select what suits your due diligence needs best. We help determine the exact requirements a company has for ESG due diligence tooling, based on both their internal expertise and existing engagement systems.
Impact-driven
We are a truly motivated team that is proud of the fact that we support our clients in making value chain due diligence work for the organization while maximizing impact. A win-win for all (affected) parties involved.
