Start of Career
In 1991, John Pettigrew joined National Grid as a graduate trainee. This marked the beginning of a career that would span more than three decades within the same organisation, a path increasingly rare in modern corporate life.
Starting at entry level gave him direct exposure to operational realities. Rather than bypassing foundational roles, he learned the business from the inside, building credibility that later proved invaluable when leading thousands of employees.
Rise Through National Grid
Over the years, Pettigrew progressed through a series of operational and executive roles across both the United Kingdom and the United States. Each position deepened his understanding of electricity and gas networks, regulation, and infrastructure resilience.
His rise was not instant. It required patience, adaptability, and resilience. This gradual progression allowed him to lead with authority grounded in experience rather than title alone, a quality often praised by colleagues and industry observers.
Becoming CEO of National Grid

The position carried immense pressure. Decisions made at this level affected national reliability, long-term investment, and public trust. Pettigrew’s leadership combined caution with clarity, balancing stability with the need for adaptation.
Leadership Style and Philosophy
As CEO of National Grid, Pettigrew became known for a calm, methodical leadership style. He favoured collaboration, long-term planning, and operational excellence over dramatic gestures.
However, leadership at this level also involved difficult trade-offs. Regulatory pressure, public scrutiny, and infrastructure demands meant not every decision was popular. His ability to absorb criticism while maintaining direction defined his tenure.

Income and Net Worth
During his time as CEO of National Grid, Pettigrew received executive compensation consistent with leadership of a major listed utility. His income came from salary, performance incentives, and long-term awards.
His estimated net worth is largely derived from these earnings and board roles. While financially successful, his public image remained centred on responsibility rather than personal wealth.

John Pettigrew is married and is the father of two daughters. Despite the demands of executive leadership, he has consistently maintained a private personal life.
He is known for valuing family balance, an aspect that humanises his public image. This separation between professional responsibility and private life reflects discipline rather than distance.
Retirement and Recent Developments
In 2025, Pettigrew stepped down as CEO of National Grid after nearly a decade in the role. His departure marked the end of an era defined by continuity and internal leadership development.
Following his retirement, he accepted board responsibilities, ensuring his experience continues to contribute to corporate governance without the pressures of day-to-day executive management.
Legacy and Impact
John Pettigrew’s legacy is rooted in consistency. Rising from graduate trainee to CEO of National Grid, he demonstrated that long-term commitment can still lead to the highest levels of leadership.
Positively, he is remembered for stability and operational understanding. Critically, his tenure also shows the heavy burden leaders carry in sectors where failure is not an option. This balance defines his lasting professional impact.
