UK Energy Market Report - 12 June 2026

UK wholesale gas and power update, NBP day-ahead at a multi-week high on a Norwegian supply outage while Brent crude eases.

UK wholesale gas and power held a firm tone into the end of the week, with the day-ahead gas contract pushing to a multi-week high as a fresh Norwegian supply outage collided with a persistent geopolitical risk premium. The standout, though, was the split in direction across the energy complex, gas and power gripped tight to the supply story while oil sold off more than 2 per cent, a reminder that the current strength in the UK market is being driven by the gas balance rather than the wider commodity backdrop.

Gas Market

NBP day-ahead settled at 124.00 p/therm, up around 6.25 p/therm on the day and the highest in several weeks. The move was driven almost entirely by supply. An unplanned compressor failure at Norway’s Troll field, layered on top of scheduled annual maintenance, dragged total Norwegian nominations down towards 280 mcm/day and cut flows to the UK by roughly 25 mcm/day, mostly across the Langeled pipeline. With Britain leaning on Norwegian molecules through the shoulder season, any interruption of that scale feeds straight into the prompt.

The curve firmed alongside the front. Winter-26 closed near 124.20 p/therm, also a multi-week high and up around 3.6 per cent on the week, while Cal-27 sat close to 95.50 p/therm. The summer-27 contract, by contrast, eased to roughly 86.57 p/therm, leaving a wide gap between next winter and the following summer that continues to reward buyers who can shape volume away from the cold months. European prices moved in lockstep, with TTF day-ahead assessed around €50/MWh, its highest since mid-May. Cooler forecasts across north-west Europe and thin storage are keeping a floor under the whole curve. Businesses weighing their options here should read our guidance on flexible energy procurement.

Electricity Market

Power tracked gas higher. Day-ahead baseload was assessed around £109.30/MWh, with the prompt caught between firmer gas input costs and a softer renewables picture. Wind supplied close to 20.8 per cent of GB demand, with solar adding around 12.5 per cent, leaving combined-cycle gas plant to fill the gap at roughly 8.6 GW, or about 28 per cent of the mix. Reduced nuclear availability has lifted reliance on gas-fired generation, which is why power has been so sensitive to the Norwegian story this week.

Forward power followed the same pattern as gas. Winter-26 baseload firmed to about £105.76/MWh, up close to 1.8 per cent on the day, while summer-27 sat far lower at around £78.82/MWh and Cal-27 near £84.77/MWh. The shape of that curve, expensive winters and cheaper summers, is the single most useful signal for any buyer structuring a contract right now, and it sits at the heart of a sensible energy procurement strategy.

Oil, Carbon and Global Commodities

Crude went the other way. Brent slipped back to around $88.40 a barrel and WTI to roughly $85.91, both down more than 2 per cent on the session as traders banked profit on the recent geopolitical rally and looked through to a comfortable supply outlook for later in the year. That divergence matters: it tells you the firmness in UK gas and power is a regional supply story, not a broad energy-wide surge. Carbon stayed supported, with the EUA December contract near €77.50 a tonne, and Asian LNG kept its premium over Europe, with JKM around $18.89/MMBtu pulling flexible cargoes east rather than into the Atlantic basin.

Storage and Supply Outlook

The deeper concern behind the week’s strength is storage. EU inventories are sitting at roughly 43 per cent full, the lowest for this point in the calendar since 2022, which leaves the continent with a great deal of injecting to do before next winter and very little slack to absorb supply shocks like the Troll outage. Norwegian maintenance season still has weeks to run, and while LNG arrivals into north-west Europe remain healthy, the Asian price premium is diverting some of those cargoes away. Ofgem’s wholesale market indicators remain a useful reference for tracking how these fundamentals feed through to bills.

What This Means for Your Business

The market is telling two stories at once. The near term is tight and nervous, a single compressor fault was enough to push gas to a multi-week high, and with storage low and maintenance ongoing, that fragility is likely to persist through the summer. Further out, the curve still offers genuine value: summer-27 gas and power are trading well below the coming winter, and that gap is where buyers with flexibility can lock in savings.

For most businesses the takeaway is to avoid being forced into the market on a spike day and instead build a structured plan that captures the cheaper parts of the curve while managing winter exposure.
