Mild downward pressure as wholesale gas eases from winter peaks, storage rebuilds and renewable output peaks across the UK grid.
Renewed upside risk as heating demand returns; LNG competition with Asia and any geopolitical disruption could push the cap back above £1,700.
What 2026 means for your bill
For a typical UK home using 2,700 kWh of electricity and 11,500 kWh of gas, every 5% movement in the price cap is worth roughly £85–£90/year. If you're on a standard variable tariff in 2026, you'll absorb every cap change directly. If you're on a fixed deal, you're shielded until renewal — which is why the next 6 months will be a critical window for switching decisions.
Should you fix in 2026?
With short-term softening but medium-term winter risk, locking in a competitively priced 12-month fixed tariff this spring can hedge against next winter's likely rise — provided exit fees stay under £75 per fuel and the fix is at least £100 below the current cap.
