When Russia invaded Ukraine in February 2022, most people in the UK did not immediately think about their energy bill or supermarket shop. Within months, they had good reason to. Ukraine and Russia together supply a significant share of the world's wheat, sunflower oil, and fertiliser. Russia is one of the world's largest natural gas exporters. The disruption to those markets sent prices across Europe — including the UK — sharply higher.
Four years on, the immediate crisis has passed. But its effects are still embedded in UK household budgets in ways that are easy to underestimate.
Energy: the most dramatic impact
Before 2022, Europe had built significant dependency on Russian pipeline gas. When Germany, the UK, and other European nations accelerated their move away from Russian energy, global gas markets tightened sharply. Liquefied natural gas (LNG) from the US, Qatar, and Norway became more valuable as European buyers competed for it.
The UK was not directly dependent on Russian pipeline gas (it imports mostly via Norway and its own North Sea production), but it is part of the global gas market. When global gas prices spiked, UK wholesale prices spiked with them.
The result: the Ofgem price cap, which had averaged around £1,050 per year for a typical household before 2022, rose to levels that would have meant bills over £3,000 a year at the 2022 peak. The government's Energy Price Guarantee kept actual bills lower — at enormous public cost — but even at the capped level, bills were roughly double their pre-war norm.
Where things stand in 2026: Global gas prices have eased significantly as LNG supply expanded, Europe built out storage capacity, and demand management measures took effect. The UK price cap is now approximately £1,700–£1,800 per year for a typical household — lower than the crisis peak but still around 60–70% above where it was before the invasion. The permanent price level has shifted upward.
Food: the fertiliser and grain effect
Ukraine is one of the world's largest exporters of wheat, maize, barley, and sunflower oil — collectively sometimes described as the "breadbasket of Europe." Russia is a major fertiliser producer, particularly for nitrogen-based fertilisers derived from natural gas.
When the war began:
- Ukrainian grain exports were disrupted, with port blockades in the Black Sea constraining shipments.
- Russian fertiliser exports faced sanctions and logistical constraints.
- The cost of nitrogen fertiliser surged, raising production costs for farmers worldwide.
- Sunflower oil — used extensively in food manufacturing — became scarce, forcing substitution to other oils that were themselves in tighter supply.
UK food price inflation peaked at over 19% annually in early 2023 — the highest in decades. Supermarkets struggled to maintain price points on basics including bread, eggs, dairy, cooking oil, and pasta.
Where things stand in 2026: The Black Sea Grain Initiative, while fragile, partially restored Ukrainian grain exports. Fertiliser prices have come down from peak levels. Food inflation has moderated substantially. But — and this is the key point — moderated inflation means prices are rising more slowly, not that they have fallen back. A loaf of bread, a litre of cooking oil, or a kilogram of pasta costs meaningfully more in 2026 than it did in 2021. These prices are not reverting.
ONS data consistently shows that lower-income households have been disproportionately affected, since food represents a larger share of their overall budget.
The hidden transmission: fertiliser and farming costs
Even UK-produced food has been affected. British farmers faced dramatically higher costs for fertiliser, fuel, and animal feed through 2022–2024. Many passed these costs on; some absorbed them at the cost of their margins. Agricultural labour shortages — partly connected to post-Brexit changes in EU worker mobility — compounded the pressure.
The result is that even food produced in the UK became more expensive. This is a less visible effect than gas prices, but it is a real one that contributed to the food inflation spike.
The indirect effects on UK households
Beyond energy and food, the war has had several secondary effects relevant to personal finance:
- Higher mortgage rates: the Bank of England raised interest rates sharply to combat inflation, which was itself heavily influenced by energy and food prices. Those rate rises fed directly into mortgage costs. Although the Bank has since begun cutting rates, they remain above pre-2022 levels and will do so for the foreseeable future.
- Transport costs: diesel and petrol prices spiked in 2022 and have not returned to pre-war levels. Anyone who commutes by car has absorbed this permanently.
- Business costs: higher energy and input costs led many businesses to raise prices across their product ranges. The inflationary pressure was broad-based, not limited to energy and food.
What this means for your budget in 2026
The practical message for anyone budgeting in 2026 is this: do not use pre-2022 mental models for what things should cost. Your energy bills, food shop, and transport costs are all permanently higher than they were five years ago, and the baseline has moved.
A few concrete anchors for 2026 budgeting:
- Groceries for one person: budget £200–£300 per month for a moderate but not extravagant diet.
- Groceries for a couple: £350–£500 per month depending on eating habits.
- Energy (one-bed flat): £80–£100 per month is reasonable; more in older properties.
- Petrol: the pump price per litre remains well above pre-2022 levels. Budget accordingly if you drive regularly.
These figures are not punishment for something outside your control — they are simply the financial reality of the current environment. Planning around them accurately is more useful than comparing them to a world that no longer exists.
Looking ahead
The longer-term trajectory depends heavily on how the war resolves, how quickly European energy infrastructure diversifies (including renewable build-out), and whether global grain markets normalise fully. None of these outcomes are certain.
What is certain is that energy transition investment — wind, solar, heat pumps, improved insulation — is accelerating partly as a direct response to the vulnerability exposed by the war. Over a 5–10 year horizon, that transition should bring greater energy price stability for UK households. In the near term, the elevated baseline is where we are.
