UK Energy Market Report - 4 June 2026

UK wholesale gas and electricity market update for 4 June 2026 – NBP prices, day-ahead power, Brent crude and procurement guidance for UK businesses.

UK wholesale gas prices softened through this week’s sessions, with NBP day-ahead settling around 115.70 p/therm after a 6% weekly pull-back from Monday’s spike above 120 p/therm.

The easing reflects improved system balance and stronger wind output, but a threatened oil workers’ strike in Norway, due to begin 5 June, is sitting over the market. Buyers considering contract action this week should weigh that risk carefully before assuming current prompt levels represent a stable floor.

Gas Market

Day-ahead NBP closed around 115.70 p/therm on Wednesday, down from the 120.86 p/therm peak seen on Monday when Middle East tensions escalated and Norwegian supply dropped toward 281 mcm/day.

Outages at Aasta Hansteen and Oseberg were the principal cause. Flows recovered to roughly 290 mcm/day by Tuesday, and the UK system moved comfortably long, sitting approximately 11 mcm/day above requirement, which gave the market room to give back most of Monday’s gains.

The near-curve is essentially flat. July-26 is priced at 114.79 p/therm, Q3-26 at 115.28 p/therm, and Winter-26 at 117.31 p/therm.

That winter premium of just under 2 p/therm over the spot is modest, reflecting reasonable confidence that European storage will refill adequately before the cold season, provided Norwegian supply holds.

The long end tells a very different story. Summer-27 is at 85.27 p/therm and Cal-27 at 92.97 p/therm, a meaningful discount to today’s prompt. Cal-28 drops to 72.01 p/therm and Cal-29 to 64.76 p/therm.

That structural backwardation has been a consistent feature of the forward curve for several months, and it makes a strong commercial case for longer-dated fixed procurement where volumes and risk appetite allow.

The Norwegian strike scheduled for 5 June is the market’s primary near-term concern. Norwegian gas accounts for roughly 30% of UK pipeline imports on a typical day, and any prolonged action would tighten the system faster than LNG arrivals could compensate.

The prompt could move 10-15 p/therm higher quickly if the action proceeds as planned. Markets have priced in some caution but not an acute supply shock, which means upside risk to near-term prices remains significant.

TTF front-month is around 48-49 EUR/MWh. JKM LNG settled at 18.17 USD/MMBtu, with a heavy schedule of US cargoes flowing into north-west European terminals continuing to provide a backstop against deeper tightening.

European storage stands at just over 40% capacity, running approximately 9% behind the seasonal average compared to this time last year.

Electricity Market

UK day-ahead baseload settled around 96.99 GBP/MWh on Wednesday, recovering from a sharper peak of 111 GBP/MWh earlier in the week when weak wind and a combination of nuclear outages pushed demand onto gas-fired plant.

At one point, CCGTs were supplying close to one-third of the GB generation mix, an unusually high share for early June.

The nuclear outage picture remains congested. Heysham, Torness, Sizewell B and Hartlepool are all affected, trimming available baseload capacity and keeping power prices firmer than the gas-only picture would suggest.

Wind output has recovered somewhat, easing the prompt, but Q3-26 at 100.47 GBP/MWh and Winter-26 at 102.09 GBP/MWh reflect ongoing uncertainty about the generation mix through the coming months.

As with gas, the long end of the power curve is in steep backwardation.

Summer-27 is at 78.12 GBP/MWh and Cal-27 at 84.12 GBP/MWh. Cal-29 at 65.31 GBP/MWh points to sustained growth in cheap renewables displacing gas-for-power demand over the next few years, a reasonable structural assumption given the rate of new wind and solar capacity coming onto the UK grid.

Oil, Carbon and Global Commodities

Brent retreated to 96.97 USD/barrel on Wednesday, off 0.86% as the market gave back part of Monday’s sharp rally. WTI moved in a similar direction, settling around 93.50 USD/barrel.

The Middle East backdrop remains tense, with Iran having paused indirect negotiations earlier this week, and partial disruption to global LNG shipping through the Strait of Hormuz maintaining a risk premium across crude, gas and LNG markets. Until that situation either crystallises or eases, commodity markets are likely to stay more volatile than near-term fundamentals alone would justify.

EUA carbon for December 2026 delivery is at 79.17 EUR/tonne. That level remains broadly supportive for gas-for-power margins, though any material weakness in carbon could affect the economics of CCGT dispatch on lower-demand or higher-wind days.

Storage and Supply Outlook

European gas storage at just over 40% capacity is the structural number to keep watching. The injection season is running nine percentage points behind the same point last year.

That alone is not critical, summer is a long time in energy markets, but it means any disruption to Norwegian supply or LNG arrivals over the next three months will land on an already-stretched storage position. The margin for error heading into winter 2026/27 is narrower than most buyers will be comfortable with.

UK LNG arrivals remain well-supported, with a heavy schedule of US cargoes flowing into north-west European terminals. That provides some compensation for reduced Norwegian volumes, but it is not an elastic backstop.

Asian demand shifts, shipping disruptions and terminal constraints can all redirect cargoes at short notice. No Ofgem announcements have been made this week relevant to commercial buyers, though the regulator’s review of default tariff structures continues in the background.

What This Means for Your Business

This week’s prompt softening is a real opportunity, but not necessarily a lasting one. If you are approaching renewal or reviewing your procurement strategy, conditions now are meaningfully better than they were in early May, and considerably better than twelve months ago.

The risk of waiting for further downside is asymmetric: a Norwegian strike tomorrow or further escalation in the Middle East could shift the near-term market quickly, and the downside from here is limited given where storage currently sits.

For buyers with longer contract horizons, the backwardation in the long-dated curve is worth taking seriously. Cal-27 gas at 92.97 p/therm against today’s spot around 115.70 p/therm, or Cal-27 power at 84.12 GBP/MWh against a current prompt above 97 GBP/MWh, represents genuine value certainty at a forward discount. If your budget and risk appetite support it, fixing at the long end now may look like an obvious decision in twelve months.

If you are on pass-through or flexible pricing, this week is a reasonable moment to review your exposure before any Norwegian disruption changes the near-term market.
