UK Energy Market Update - Prices Stable Amid High Renewables and Mild Autumn Demand - 28th October 2025

Steady markets continue as strong wind and stable supply balance autumn demand.

Both gas and electricity markets remained calm and well-supplied last week, with prices holding steady amid mild weather and high renewable generation. Wind output frequently exceeded 18–20 GW, easing pressure on gas-fired plants and helping maintain balanced system margins.

For now, the UK energy market remains defined by stability a combination of strong renewables, healthy imports, and robust gas supply keeping volatility at bay as we approach November.

Electricity Market: Wind and Nuclear Boost Stability

UK wholesale electricity prices traded within a narrow range last week, supported by strong renewables and improving baseload capacity. Day-ahead baseload averaged around £80–82/MWh, while forward contracts held firm for Q4 as traders maintained confidence in supply heading into winter.

Key drivers included:

• High wind generation across the latter half of the week, frequently exceeding 18–20 GW and reducing reliance on gas-fired generation.

• Improved nuclear availability, with the return of the Heysham units boosting zero-carbon baseload output.

• Steady interconnector imports from France and the Netherlands, enhancing grid flexibility during lower wind periods.

• Typical seasonal demand, as mild autumn temperatures kept consumption moderate and system stress minimal.

Overall, the electricity market continues to show resilience, with strong renewable output and improved nuclear performance ensuring healthy margins and low volatility.

Gas Market: Comfortable Supply and High Storage Keep Prices Contained

UK wholesale gas prices edged slightly lower, with the NBP day-ahead contract averaging around 79p/therm. Ample supply, record European storage, and mild weather continue to underpin a stable and confident outlook.

Key factors shaping the week included:

• Steady North Sea and Norwegian pipeline flows, maintaining consistent supply following maintenance outages.

• Multiple LNG cargo arrivals keeping terminal send-out robust.

• European gas storage at record highs, reinforcing security of supply and limiting upward price risk.

• Stable carbon pricing around £55/t, exerting mild pressure on high-emission generation but not enough to drive price swings.

Even as the heating season approaches, the combination of strong supply fundamentals and limited demand growth continues to cap volatility across gas markets.

Bright Edge View: Stability Now, But Don’t Wait for Winter

The UK energy market remains steady but this balance could shift quickly if colder weather or supply interruptions emerge in the weeks ahead. While current fundamentals are positive, forward contracts are already pricing in winter risk, suggesting that market confidence doesn’t always guarantee low prices later.

For businesses, this is a key window to secure competitive energy rates before the seasonal uplift begins. At Bright Edge, our energy brokers continuously track these wholesale movements to help organisations lock in stability, avoid winter volatility, and manage long-term cost efficiency.
