The call

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.

Why
01
AI pressure: Octopus Energy's Kraken AI platform. Octopus runs customer service and pricing on an AI-heavy Kraken system, letting it undercut British Gas on cost and already overtaking it in electricity share. Could AI do the core job? Unlikely.
02
Bigger players: None apparent. No large tech or oil major is currently pushing into UK household energy retail or the nuclear/gas-storage infrastructure Centrica runs. Could a giant copy it? No, they are blocked.
03
What protects it. Regulated UK licenses, nuclear and gas-storage assets, and a 7,000-strong field engineer network Octopus cannot quickly replicate.
What would change this call
British Gas domestic customer count in H2 2026 and FY2026 results versus 7.45m at H1 2026. Falling count would confirm continued customer loss to rivals like Octopus.
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.
Key numbers
  • FY2025 adjusted EBITDA fell to £1.4bn from £2.3bn (2026-02-19)
  • British Gas customers dropped to 7.45m in H1 2026 (2026-07-23)
  • £2bn buyback cut shares outstanding by ~25% in 2025 (2026-02-19)
Named risks
  • Retail customer base shrinking (7.5m to 7.45m in H1 2026) as Octopus takes share. Severity: medium
  • Ofgem prepayment-meter compliance review could yield further costs beyond £90-112m already booked. Severity: medium
  • Sizewell C is a multi-decade, £38bn project with COD not until mid-late 2030s, exposing Centrica's £1.3bn cap to overrun risk. Severity: medium
  • Union disputes over AI-driven job cuts framing could generate labor relations and reputational fallout. Severity: low
  • Statutory operating profit collapsed to ~£0.1bn in FY2025 on exceptional charges, showing earnings volatility. Severity: high

Questions people ask
Is Centrica profitable in 2026?
Yes but weaker: FY2025 adjusted operating profit fell to £814m from £1.552bn in 2024, and statutory operating profit collapsed to roughly £0.1bn on exceptional charges, per Centrica's 19 Feb 2026 preliminary results. H1 2026 retail operating profit rose to £346m from £338m.
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.
Who owns Centrica and British Gas?
Centrica plc is a fully public FTSE 100 company on the London Stock Exchange (ticker CNA), with no controlling parent. Top institutional holders as of mid-2026 include BlackRock Fund Advisors (~87.7m shares) and Vanguard, per Fidelity data dated 9 July 2026.
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.
What is Centrica's biggest competitor?
Octopus Energy is Centrica's most pressing rival in UK retail energy, having overtaken British Gas in electricity market share (25.7% vs 20.4%) by July 2026 and ranking far higher on customer satisfaction per Which?'s 18 January 2026 survey.
