Why executive wellbeing is a board-level metric

In NHS clinics I've seen plenty of senior leaders — but never as part of their job. They came in privately, quietly, often years after the warning signs. By then we were managing damage, not preventing it.

That gap between "the executive team works hard" and "the executive team is clinically supported" is where most companies sit today. And it's a more expensive gap than most boards realise.

The replacement cost no one models

Leadership replacement isn't a salary line. Harvard Business Review estimates senior executive replacement at 213% of annual salary when you factor in search fees, lost productivity, transition risk and team disruption. For a CTO on £250k, that's over £500k of direct cost — before you price in deal slippage, missed product cycles, or the strategic drift that happens during a 6-month gap.

At the founder level, the number is uncountable. An unexpected leave of absence at Series B can trigger a down-round, a covenant breach, or a strategic pivot the company isn't ready for.

What clinical risk actually looks like at the top

The pattern is consistent across the leaders I've assessed:

• Sleep debt measured in years, not weeks
• Cardiometabolic risk markers drifting silently for 3–5 years
• MSK issues ignored because there's no time, until they aren't ignorable
• No primary care relationship because the NHS GP gets a 10-minute slot every 18 months

None of this is dramatic in any single quarter. All of it compounds.

What a board-level wellbeing programme looks like (and doesn't)

It is not an annual private medical with a 200-question form and a 15-minute GP review. That's a screening transaction, not a relationship.

It is:

1. A named clinician — physio, GP-equivalent, or both — with a continuous record of the executive's health
2. Quarterly check-ins, not annual ones, because the leading indicators (sleep, recovery, training load, blood pressure trend) move quarterly
3. Direct triage when something goes wrong, so the executive isn't spending political capital chasing referrals
4. Confidentiality that the executive trusts implicitly — clinical record, not HR record

Why this belongs on the board agenda

If the board reviews key-person insurance, succession planning and continuity risk, executive health is the leading indicator for all three. Treating it as a perk under the People function understates what it actually protects.

The boards that get this right tend to be the ones whose chair has personally lost a CEO or co-founder mid-cycle. The rest are running on the assumption it won't happen to them.
