At the end of September, the UK diesel average climbed to 199.18p a litre, eclipsing the record set in the feverish summer of 2022, and by then a quarter of British forecourts had already crossed the £2 threshold. Somewhere between the pump nozzle and the receipt, ordinary Britons are paying the instalments on a war they never ordered.

Oil: The Slow Bleed

Since Trump struck the match on 28 February, Europe has been breathing the secondhand smoke of a war that has shattered the oil markets beyond repair. Anyone following this war has learned to distrust the word “imminent”, much of it due to the American diplomatic farce performed in monthly instalments.

In May, Trump declared a deal with Iran “largely negotiated.” By June, he was assuring the world the strait would be fully open within the week. In August, the circus continued, with US officials claiming an agreement could be signed within 48 hours. Each announcement nudged oil lower for an afternoon, and each collapsed soon after.

Consequently, Europe has been planning its winter around a fiction. Tehran, emboldened by the stalemate, has floated the idea of making European countries pay for the strait’s upkeep. Europe, in other words, is being asked to pay rent on a house someone else set alight. Furthermore, when Saudi Arabia’s pipeline to the Red Sea was crippled by Houthi attacks in September, Aramco told European buyers to expect nothing in October.

After the invasion of Ukraine, Europe rightly turned its back on Moscow’s crude and fuels, and in January 2026 it went further, banning diesel refined from Russian crude in countries such as India and Turkey. The gap was filled by the Gulf, as Saudi Arabia and Kuwait became major diesel suppliers to Europe in Russia’s place. Europe, in effect, traded one dependence for another, and Washington then set the replacement ablaze.

Natural Gas: A Thinner Blanket

Gas is where winter will truly bite. Storage stood at 68.49% in mid-September, sixteen points beneath the five-year norm, and the injection season has all but closed. Consequently, Europe enters the heating months with a thinner blanket than at any point in recent memory.  The damage, meanwhile, runs far deeper than rhetoric. Gulf LNG exports still crawl along at 15 to 25 percent of their pre-war volumes, and Qatar’s emergency suspension of contracted shipments now stretches into early November.

Some wounds will outlast any ceasefire in the region, since strikes on Ras Laffan have knocked roughly 17% of capacity offline, with repairs measured in years. Energy Aspects warns that a cold winter without Qatari supply could drive average prices to €110/MWh, and that a prudent attempt to keep a safety buffer might push them to €210. Here, too, sanctions tighten the knot. Russia still supplied 12.5% of EU gas imports, and Brussels will ban Russian LNG from 1 January 2027, closing one more door in the very depths of winter.

Those figures translate into human terms with brutal speed. Gas sets the price of electricity across much of the continent, so every spike ripples into homes that heat with neither gas nor oil. Families who weathered 2022 by drawing down savings now face a second siege. Governments that spent lavishly on support schemes four years ago find their coffers depleted and their bond markets watchful. The safety net, in short, has frayed precisely when more people are about to fall.

The Atom as Armour

If this winter teaches Europe anything, it is that energy bought from distant straits is energy held hostage. Every tanker that must thread Hormuz, every cargo that must outbid Shanghai or Tokyo, leaves the continent’s fate at the mercy of someone else’s war.

Nuclear power offers a way out of that captivity. A reactor needs fresh fuel only every year or two, its uranium can be sourced from stable partners such as Canada and Australia, and a modest stockpile can sit quietly in a warehouse for years. No blockade can starve a reactor in January, and no president can talk its output up or down from a podium.

Britain, for its part, has spent decades forgetting how to build them. The country’s last completed plant was Sizewell B in 1987, and its ageing fleet has been retiring faster than anything can replace it. Hinkley Point C, which should eventually power about six million homes, has become a byword for delay and overspending. Yet the lesson of Hinkley is to build more often, and to build better, since every nation that has mastered nuclear construction did so through repetition.

Sizewell C now has the government’s backing, and Anglesey has been chosen to host Britain’s first small modular reactors, beginning with up to three Rolls-Royce units and potentially eight. Each of those factory-built reactors could supply roughly a million homes, and the design is in the final stage of regulatory assessment, expected to finish by December. The foundations, in other words, are finally being poured. What remains missing is urgency.

That urgency should now come from the forecourt and the gas meter. Every pound Europe spends propping up households through another fossil-fuel shock is a pound that builds nothing lasting. Money poured into reactors, by contrast, buys decades of steady, low-carbon power that dampens the very price spikes now terrorising households.

Ultimately, energy independence is a strategic choice made years before the crisis arrives. Europe failed to make it after 2022, and it is paying the price again in 2026. Should it hesitate once more, the next war in a faraway strait will find the continent just as cold, just as exposed and just as poor. The atom offers armour, and it is time Europe put it on.
