The announcement that Prime Minister Keir Starmer will step down has created fresh uncertainty across Westminster, with Greater Manchester Mayor Andy Burnham emerging as the frontrunner to succeed him.

For businesses, however, the key question is not simply who moves into Number 10. It is what, if anything, changes when it comes to UK energy policy.

Political Change Does Not Mean Immediate Energy Market Change

While leadership contests often dominate headlines, the reality is that energy policy rarely changes overnight.

The UK’s long-term commitments to net zero, investment in renewable generation, electricity market reform and energy security are expected to remain broadly intact regardless of who leads the government next.

However, a change in leadership can influence the pace, priorities and delivery of existing policies.

For businesses managing energy costs, these details matter.

The Key Questions Businesses Should Be Asking

As the political landscape evolves, there are several areas worth monitoring closely.

Will the Approach to Net Zero Shift?

The direction of travel towards decarbonisation is unlikely to change significantly, but the emphasis could.

Future decisions around grid investment, support for industrial decarbonisation, planning reform and the balance between energy affordability and climate ambitions could all influence business energy costs over the coming years.

What Happens to Great British Energy?

One of the flagship initiatives of the current government has been the creation of Great British Energy, a publicly owned investment body designed to accelerate renewable energy projects across the UK.

A new administration may review its objectives, governance structure or investment priorities, potentially affecting the speed of renewable deployment and the wider energy transition.

Will Energy Security Become an Even Greater Priority?

Recent geopolitical tensions in the Middle East have once again highlighted the importance of energy security and the UK’s exposure to global commodity markets.

Although the UK has increased renewable generation significantly in recent years, businesses remain vulnerable to wholesale gas market volatility, which continues to influence electricity prices. Diversification of energy sources, grid resilience and domestic energy production are likely to remain high on the political agenda.

Why Businesses Should Focus on Strategy, Not Headlines

Political developments can create short-term market uncertainty, but businesses should avoid making energy procurement decisions based solely on speculation around future policy changes.

Wholesale prices are influenced by a wide range of factors, including:

• Global supply and demand
• Geopolitical developments
• Weather patterns
• European gas storage levels
• Infrastructure availability
• Network and policy costs

Political leadership is just one piece of a much larger puzzle.

The most resilient businesses are those with a clear energy strategy that looks beyond the headlines and focuses on long-term objectives, risk management and procurement planning.

What Happens Next?

With Greater Manchester Mayor Andy Burnham widely viewed as the leading contender to succeed Keir Starmer, attention is already turning to what a change in leadership could mean for the UK’s energy agenda. While no formal policy announcements have been made, Burnham’s track record suggests a continued focus on regional energy investment, infrastructure development and improving energy affordability. For businesses, the key question is not simply who becomes Prime Minister, but how any new leadership team may influence the pace and priorities of future energy policy.

Whoever becomes the next Prime Minister will inherit a complex energy landscape shaped by competing priorities: affordability, security, decarbonisation and economic growth.

For businesses, the challenge remains unchanged.

Understanding how policy decisions translate into real-world energy costs will be essential in the years ahead.
