Why every board needs a SID
When you think about boardrooms, you might imagine the chair or the CEO calling the shots. But there’s another figure quietly steering the ship from behind the scenes: the Senior Independent Director (SID).
For many UK boards, appointing this role is more than a regulatory checkbox – it’s a strategic move that balances boardrooms and transforms good governance into great governance.
But what exactly does an SID do, and why should every board have one?
A SID is neither a chair nor a NED – so what is their role?
A SID is a non-executive board member who provides independent oversight and support to enhance board effectiveness. At first glance, the role can feel a bit nebulous. They’re not the chair, but they’re not just another Non-Executive Director (NED) either.
That ambiguity is precisely where their power lies.
Senior Independent Directors are a critical counterweight to the chair and CEO, keeping the board aligned and ensuring discussions are independent, constructive and laser-focused on what’s best for the company.
Unlike their US counterpart, the Lead Independent Director (LID), who often serves as a “chair-in-waiting”, the UK-based SID role is more about:
- Facilitating transparent dialogue
- Mediating conflicts when personalities clash
- Safeguarding the board’s integrity
Think of them as the board’s wise counsellor. Whether it’s addressing concerns from shareholders or acting as a sounding board for the chair, the SID brings an independent perspective that’s crucial for effective governance.
Four key contributions of Senior Independent Directors
1. Navigating power dynamics and maintaining boardroom balance
The relationship between the SID and the chair is a high-wire act. While the SID supports the chair, they must also challenge them when necessary.
Imagine a scenario where the chair becomes too autocratic or the CEO’s influence grows too strong. This is when it’s important to have an independent party who can hit pause and question decisions when they’re veering off-track.
It’s not about creating friction for the sake of it. It’s about keeping the board from becoming a complacent echo chamber, rather than a strategic decision-making forum. The SID provides that essential layer of independent oversight, holding the chair accountable, giving everyone a voice and mitigating the risk of groupthink among directors.
2. Safeguarding the board during times of crisis
It’s easy to underestimate SIDs when things are running smoothly – but when the pressure’s on, they’re the steady hand boards need to stay the course.
Whether it’s a disagreement between the chair and CEO or a clash of egos among board members, the SID is there to mediate and bring everyone back to the table.
Beyond internal squabbles, the SID is an intermediary between the board and shareholders, especially when the heat is on from investors or regulators. In those moments, they’re the calm, composed voice that protects the company’s reputation and keeps everyone focused on long-term goals.
3. Enhancing board effectiveness through performance reviews
A lesser-known but vital part of the SID’s role is overseeing the board’s annual performance review. An effective SID engages with each board member, listening to their concerns and using these insights to identify blind spots and recommend genuine improvements.
Crucially, the SID’s role in evaluating the chair’s performance ensures that the board’s leadership remains fit for purpose.
If the chair’s effectiveness begins to wane – whether due to complacency, external pressures or just the passage of time – it’s the SID who leads succession planning, initiates the transition process and ensures a smooth appointment of a new chair, even if that means stepping in as interim chair themselves.
4. SIDs are the catalysts for a more diverse board
Boards today are under increasing pressure to embrace diversity and inclusion, so there’s a lot of talk about diversity – but sadly not enough walk.
The SID is a powerful advocate for change, ensuring that discussions about diversity go beyond tokenism and lead to meaningful action.
A forward-thinking SID will encourage the board to think about diversity in all its forms: gender, ethnicity, experience and thought. By doing so, they help build inclusive boards that don’t just look good on paper, but are genuinely passionate about driving change and better decisions.
The skills every SID needs in their toolkit
To fulfil these responsibilities, SIDs must possess the right blend of emotional intelligence (EI), strategic vision and an unwavering commitment to doing what’s right. Here are the qualities that set exceptional SIDs apart:
- The courage to challenge the status quo. Whether it’s questioning a popular decision or pushing back against the chair, it’s critical for SIDs to maintain independence of mind and prevent undue influence from an individual or group.
- Big-picture thinking helps SIDs stay two steps ahead. While everyone is caught up in quarterly results, the SID is five years in the future, keeping a long-term view on issues like succession planning, risk management and shareholder relations.
- EI skills are paramount given the SID’s role as mediator and confidant. They must be an excellent listener, master diplomat, someone who can build trust with the chair and other board members so that everyone unites towards common goals.
- Staying balanced, like knowing when to support and when to challenge, is the hallmark of a successful SID. They’re there to help the board and organisation succeed as a whole, not to get caught up in individual power plays or personal gain.
Taking on an SID role is a powerful way to deepen your impact within the boardroom, giving you the opportunity to influence strategy, champion positive change and steer an organisation through complex challenges.
