Centrica plc
British Gas owner; UK energy retailer and operator of nuclear, gas storage and LNG assets.
Centrica's nuclear and gas-storage business looks solid for years, while British Gas keeps losing ground to Octopus's AI-run rival operation.
Centrica owns nuclear plants, gas storage, and British Gas, the country's largest home energy supplier. The power infrastructure side is hard to replace because it requires huge upfront spending and government approval, but British Gas is being squeezed by Octopus Energy, a younger company that uses technology and better pricing to win customers away. The company will likely survive the next few years, but jobs in customer service and back-office work are being cut as the retail side shrinks, while roles in infrastructure and energy trading remain safer.
Whether Octopus Energy's gas supply market share overtakes British Gas's beyond current ~26.7% vs 25.9%. Would confirm Octopus has decisively displaced British Gas as gas supply leader.
Retail operating profit trend in FY2026 results versus £346m H1 2026. A drop toward negative would show cost-cutting can't offset customer losses.
- FY2025 adjusted EBITDA fell to £1.4bn from £2.3bn
- British Gas customers dropped to 7.45m in H1 2026
- £2bn buyback cut shares outstanding by ~25% in 2025
- Retail customer base shrinking (7.5m to 7.45m in H1 2026) as Octopus takes share.
- Ofgem prepayment-meter compliance review could yield further costs beyond £90-112m already booked.
- Sizewell C is a multi-decade, £38bn project with COD not until mid-late 2030s, exposing Centrica's £1.3bn cap to overrun risk.
- Union disputes over AI-driven job cuts framing could generate labor relations and reputational fallout.
- Statutory operating profit collapsed to ~£0.1bn in FY2025 on exceptional charges, showing earnings volatility.

- Could AI replace British Gas customer service jobs?
- It already is: in July 2026 Centrica announced cuts of 1,300 customer-service and back-office roles, a 14% reduction in that function, citing 'targeted deployment of AI tools' and a ~20% year-on-year drop in call volumes as digital channels take over.

- Is Centrica losing to Octopus Energy?
- In retail supply, yes on some measures: as of July 2026 Octopus held ~25.7% UK electricity share versus British Gas's ~20.4%, overtaking it in electricity, though British Gas still led gas supply at ~26.7% versus Octopus's ~25.9%, per confused.com data dated 2 July 2026.
- Is it safe to take a job at Centrica right now?
- It depends on the division: infrastructure and field-engineering roles are stable, backed by nuclear, gas storage and LNG assets, but Centrica cut 1,300 customer-service and back-office jobs in July 2026, a 14% reduction in that function, as digital/AI tools replace call handling.
