British Gas profits tumble as household supply arm sees £80m hit

London : British Gas owner Centrica saw annual profits nearly halve in 2025, dropping to £814 million from £1.55 billion in 2024.
The decline was driven by an £80 million impact from unusually warm weather and a shift of customers to cheaper fixed-price deals. Household supply profits fell 39% to £163 million, with 32% of customers now on fixed tariffs, up from 25% last year, reducing overall margins. Despite the challenges, Centrica grew its UK and Ireland household customer base for the first time in over a decade.
Total customers rose 1% to 7.96 million, aided by 91,000 accounts acquired from failed suppliers Rebel Energy and Tomato Energy.
Chief Executive Chris O’Shea said the company remained disciplined, delivering operational performance while achieving retail customer growth across all businesses.
The results underline how weather and tariff changes can weigh on energy profits, even as customer numbers show modest expansion. — dpa
