Centrica's first-half profit falls due to mild weather, lower energy prices

Centrica, owner of British Gas, reported a halving of its first-half adjusted operating profit to £500 million, down from £1 billion, primarily due to mild weather, falling wholesale energy prices, and weaker returns from its gas storage operations. This performance reflects challenging market conditions impacting its retail and energy trading segments. Despite the profit decline, the company plans to raise its full-year dividend by 22% and has invested in a 15% equity stake in the Sizewell C nuclear project, while also seeking regulatory support for its Rough gas storage facility to ensure its long-term viability.

Analysis

Centrica's first-half 2025 financial results reveal a significant contraction in profitability, with adjusted operating profit halving to £500 million from £1 billion year-over-year. This decline is directly attributed to external headwinds, including milder weather that suppressed residential energy demand for its British Gas arm, and falling wholesale energy prices which limited opportunities in its trading business. A key operational pressure point is the Rough gas storage facility, now projected to incur an adjusted operating loss of £50 million to £100 million for the year, with the company explicitly stating the situation is "not sustainable" without a new regulatory support mechanism. Further signs of operational weakness appeared in the services & solutions division, which recorded a 2% decline in its customer base. Despite these challenges, which prompted a 1.2% drop in the share price, management is signaling confidence through two key strategic actions: a commitment to a 22% increase in the full-year dividend and a long-term investment in a 15% equity stake in the Sizewell C nuclear project, which targets a 10.8% return on equity.

Key Decisions for Investors

• Investors should weigh the severe 50% drop in first-half operating profit, driven by market conditions, against management's commitment to a 22% dividend hike, assessing whether this capital return policy is sustainable.
• The future of the Rough gas storage facility presents a key risk, as its projected operating loss and explicit dependence on a new regulatory framework for future viability must be closely monitored.
• Consider the long-term strategic pivot towards regulated assets, evidenced by the Sizewell C nuclear investment, while scrutinizing for a turnaround in the underperforming services & solutions division, which saw a 2% customer decline.
