About us

Honestly forward

We verify with a genuine understanding of your business. Because understanding is a kind of psychological fuel. It lowers defences. That makes honesty possible, allowing us to establish more clearly where you currently stand. And that's essential to move forward.

Frequently asked questions

Want to know more about how we help companies become more sustainable?

  • What makes Fira different?

    We combine independent assurance with a genuine interest in and understanding of your business. We don’t just come looking for mistakes to point fingers at. We take the time to understand how your organisation works before we assess it. That deeper understanding leads to better insight. And we believe that’s the foundation of clear, independent sustainability assurance.

  • Why does independent sustainability assurance matter?

    Because sustainability has become part of doing business. Claims need evidence. Customers, banks, investors and business partners want confidence that your sustainability claims hold up. Our independent assurance provides that confidence, without passing judgment.

    We don’t provide assurance to judge, but solely to establish the facts with clarity, so you know exactly where you stand. The result? Greater trust. Greater credibility.

    Customers, banks, investors and supply chain partners increasingly expect evidence. Organisations that can’t substantiate their claims risk losing trust and damaging their reputation.

  • Does Fira only provide assurance, or do you also help organisations improve?

    We're an organisation that measures and verifies sustainability: assurance, in other words. But we do it in a way that encourages improvement. We verify with a genuine understanding of your business. Understanding lowers defences. That allows us to verify your sustainability performance even more thoroughly. Which means you can improve more effectively, make better choices, and take on sustainability yourselves.

  • What type of organisation does Fira work with?

    We provide assurance across every industry and sector. Our ideal clients are organisations that take sustainability seriously and want to communicate about it honestly. From SMEs to large enterprises. Whether you’re just getting started or already well advanced, independent insight always adds value.

  • What does “Honestly forward.” mean?

    It means real progress starts with knowing exactly where you stand. Not with polished stories or empty claims, but with honest insight. Because honest insight creates direction. It builds trust. And it gives organisations the confidence to keep moving forward.

  • How much does sustainability assurance or a TIM Rating cost?

    Every sustainability assurance engagement and every TIM Rating is different. That’s why we first take the time to understand your organisation and your objectives before preparing a proposal. You’ll receive that proposal within one working day of our introductory meeting, so you’ll know exactly what to expect.
