A shop that now costs £139
The basket of groceries that cost you £100 in January 2020 now costs £138.60. That is a painful number. It comes from the Office for National Statistics. This increase of 38.6 per cent reflects the cumulative pressure on food prices over more than six years, a period which has seen supply chains snap and energy costs spiral. For a family doing a weekly shop, this is not an abstract percentage but a concrete cost. It is an extra £38.60 that has to be found from somewhere each week. Nothing has changed except the price.
That figure changes a household budget entirely. The additional £38.60 weekly spend translates to an extra £167 per month, or just over £2,000 a year, for the same trolley of food. It is the price of a family holiday. It is the cost of running a small car. The money must be found. For millions of people, that has meant cutting back, switching to cheaper brands, or simply buying less. The cumulative effect of small, persistent price rises has fundamentally altered the affordability of basic goods in the United Kingdom. This is not a temporary shock. It is a new reality.
Now another number enters the equation. Four per cent. Industry analysts predict food inflation will approach an annual rate of 4 per cent by Christmas. This is not a price cut. It is not even a price freeze. It means that the new, higher prices will continue to rise, just at a slower pace than before. The shop that already costs £138.60 will see its price climb higher still. At a 4 per cent rate of inflation, that weekly shop would increase by another £5.54 over a year. The total bill would then be £144.14. People should not expect relief. Prices will keep rising.
The pressures are not easing
The forces driving prices higher have not vanished. They are now embedded in the system. Chief among them is the cost of energy. Food production runs on energy at every single stage of its journey from a field in Lincolnshire or a farm in Spain to the kitchen table. Farmers need gas to produce the fertilisers that grow crops, and they need diesel to run the tractors that harvest them. Food processors need vast amounts of electricity and gas to cook, pasteurise, and package the goods that fill supermarket aisles. Everything gets cold. Refrigeration of warehouses and transport is a constant drain on power, as are the chilled aisles in the stores themselves. These are not small costs. They are fundamental inputs. And while wholesale energy prices may fluctuate, the fixed contracts signed by businesses mean price falls are slow to reach the factory floor. The pain remains.
Then there is the cost of labour. People cost money. Staff must be paid. From the workers picking vegetables to the drivers transporting chilled goods overnight and the employees stacking shelves for the morning rush, wages have been rising. Increases in the National Living Wage have set a higher floor for pay across the economy, while intense competition for workers in critical sectors like haulage has forced companies to offer more attractive terms. These are not discretionary costs that a business can choose to absorb indefinitely. They are passed directly to the customer in the form of higher prices on the shelf. The price of a pint of milk includes the wage of the dairy farmer, the tanker driver, and the checkout operator. Every salary has gone up. Every price reflects it.
Moving food has also become permanently more expensive. This is not just about fuel. The system is slower. New rules for importing goods from the European Union have introduced a layer of cost that did not exist before 2021. A lorry of French apples now requires extensive paperwork, health certificates, and physical inspections, all of which adds time and expense to every single consignment. The paperwork is a cost. The vet’s signature is a cost. These are not temporary problems. They are now a structural feature of Britain’s supply chain. This new friction is permanent.
These pressures are not separate. They are connected. Higher energy prices push up the cost of packaging materials like plastic and glass, while also making it more expensive for workers to commute to their jobs in rural food processing plants. The shortage of lorry drivers is made worse by the rising cost of fuel. All these factors create a powerful, persistent inflationary current running through the entire food economy. They form a base of higher costs for everyone in the supply chain, from farmers to retailers. This is why the rate of price rises is slowing, not reversing. The fundamental costs are locked in. The new price level is the floor. From here, prices will only go up.
Slowing down is not reversing
Politicians celebrate falling inflation. This is a profound misdirection. A slower rate of price rises is not the same as falling prices. It is not relief. Your weekly food shop is still getting more expensive, every single week, and the official figures confirm that this trend will continue right up to Christmas and almost certainly beyond. The simple, brutal fact is that a slowing rate of price increases still means prices are increasing. The pain just gets worse more slowly.
The confusion is between disinflation and deflation. The distinction is critical. Imagine the economy is a car. For the past two years, the driver has had their foot pressed hard on the accelerator. That is inflation. The car was speeding up, going faster and faster, covering huge distances very quickly. Now the driver is easing off the pedal. This is disinflation. The car is no longer accelerating so fiercely, but it is still moving forwards at considerable speed, adding more miles to the clock. The total distance travelled continues to grow. Deflation is something else entirely. Deflation is hitting the brakes, stopping, and putting the car into reverse. It means going backwards.
Applied to your shopping basket, this means the 'speed' of price rises has slowed from a terrifying 19% recorded in March 2023, the highest in forty five years, to a projected rate of just under 4% by the end of this year. But the car is still moving forwards. It has not stopped. A 4% inflation rate means an item that costs £1 today will cost £1.04 in twelve months. It means a weekly shop that sets you back £139 now will cost you more than £144 by next September. The price is not falling. It is not even staying still. It is climbing, just up a less steep hill than before. Relief is not coming.
True price falls, or deflation, are exceptionally rare. Economists fear them. If people believe a television or a car will be cheaper next month, they stop buying things today, and that widespread delay in spending can cause a deep and prolonged recession. The central bank, the Bank of England, actively works to prevent this by targeting a low and stable rate of inflation, which is currently 2%. Its goal is not zero inflation. It is certainly not deflation. Widespread, sustained price cuts are a sign of a broken economy, not a healthy one. This is why your £100 shop is gone forever. It is not coming back.
Some pay a higher price
This 38.6% figure is just an average. The reality is worse for many. The pain is not shared equally. For a household in the richest tenth of the country, food accounts for a relatively small part of its weekly spending, but for a family in the poorest tenth, groceries can consume a huge and punishing share of its entire income. An aggregate price rise of almost forty per cent is therefore not an inconvenience that requires cutting back on luxuries, it is a financial catastrophe forcing impossible choices between paying for the gas bill or putting a hot meal on the table. There is no slack. There are no easy cuts to make.
These households cannot simply trade down. Many were already buying the cheapest own brand pasta and the most basic of bread, choosing the most affordable vegetables as a matter of course long before the current crisis began. Their flexibility is gone. They are trapped. The very structure of inflation in the food sector has hit them hardest, with prices for some value range items rising faster than their premium equivalents, leaving the most vulnerable with nowhere to turn. This is not a statistical curiosity. It is a daily disaster for millions.
Inevitably, attention turns to the supermarkets. They are the final link in the chain. They set the prices people see. The accusation of ‘greedflation’ has grown loud, with both campaign groups and politicians questioning whether the large grocers are protecting their profits at the expense of their customers. The numbers are vast. Seeing a company like Tesco or Sainsbury’s post hundreds of millions in profit while food bank queues lengthen invites public anger and intense political scrutiny.
The supermarkets deny this. They argue they are also victims of inflation, not its cause. Their defence is that they are caught in the middle, squeezed between huge cost increases from global suppliers and the need to keep prices low enough to compete with rivals like Aldi and Lidl. The energy to run thousands of stores and refrigerate tonnes of food has soared. So has the cost of fuel for their delivery lorries and the wages for their staff. They insist they absorb as much of this as they can, but that passing on some of the cost is unavoidable. A degree of public scepticism is understandable. The numbers are hard to reconcile. The profits are still enormous, even if the percentage margins are tight, and that visible wealth makes the supermarkets a permanent focus for discontent.
The £100 shop is gone for good
The idea of your grocery bill returning to what it was is a mirage. It will not happen. For every £100 spent on food in January 2020, shoppers are now paying £138.60, and this elevated price is not a temporary peak from which the market will retreat. It is the new foundation. A significant, sustained fall in the overall price of food is a historical and economic phantom. Believing in it is a mistake. The shock of the last few years has permanently reset the cost of eating, locking in the 38.6 per cent increase as the new reality for household budgets across Britain. The old prices are gone for good.
This is because falling prices, an economic state known as deflation, are extraordinarily rare in a modern economy. They are also deeply feared. A consistent drop in the price level sounds appealing to a struggling shopper, but to an economist it is a five alarm fire signalling a profound economic crisis. Deflation was a feature of the Great Depression in the 1930s, a time of mass unemployment and industrial collapse, because when people expect prices to fall they stop spending money, causing demand to vanish. Central banks, including the Bank of England, and the government will do almost anything to avoid it. Their entire policy framework is designed to generate a small, stable amount of inflation, not to reverse price rises that have already occurred.
The mechanics of the food industry also make price falls unlikely. Costs are sticky. They do not go down easily. Once a farmer pays more for fertiliser, a processor signs a higher wage deal for its factory workers, or a logistics firm buys diesel at an inflated price, that new cost becomes embedded in the system. Those businesses will resist any attempt by supermarkets to pay them less, as they have their own margins to protect. The stickiest cost of all is labour. A company that gives its staff a pay rise cannot simply take it away a year later, meaning higher wage bills become a permanent part of the cost structure for producing, packing and transporting food. All these higher input costs have been consolidated. They form a new, higher floor from which all future prices will be set.
Some specific products might get cheaper. A good harvest could lower the price of strawberries for a few weeks. A promotion might bring down the cost of coffee for a month. But the total cost of a weekly shop will not meaningfully decrease. The battle between supermarkets is no longer about who can offer 2020 prices, an impossible task, but about who can slow the rate of future increases most effectively. The £139 shop is here to stay. Any real relief for households will not come from cheaper food, but from the hope that their wages might one day start to rise faster than their grocery bill. That is the only way out. The baseline has shifted.
Three signals to watch
So what happens next? The future path of your grocery bill is not a mystery. It depends on three clear economic signals. These are the things to watch: the price of energy, the value of the pound sterling, and the state of the British labour market. Together, these factors form a powerful engine that will dictate whether the rate of food price increases slows to a crawl or accelerates once more, shaping the financial reality for every household in the country. They are the inputs. The price on the shelf is the output.
First, track energy. Its cost is everywhere. It is a fundamental expense woven through every link of the chain that brings food from a field to your fork. From the natural gas required to synthesise the nitrogen fertilisers spread by farmers, to the diesel that powers the tractors, combine harvesters and vast fleets of articulated lorries, and the colossal amount of electricity consumed by food processing factories, cold storage warehouses and the brightly lit chiller cabinets in every local supermarket, energy is the non-negotiable ticket to play. This makes the system incredibly vulnerable. When global wholesale prices for oil and gas rise, the cost of producing food inevitably follows. There is no escape.
Second, monitor the pound. Its strength matters immensely. The United Kingdom imports almost half of the food it consumes, making the nation’s shoppers acutely exposed to currency fluctuations. A weak pound is bad news. A one cent drop against the euro or the dollar may seem abstract, but it translates into a tangible price hike for importers buying Spanish tomatoes, Dutch peppers, Danish bacon and New Zealand lamb, a new cost that is swiftly passed on at the checkout. It is a simple transmission mechanism. A weaker currency directly imports inflation. The value of sterling is, for the food sector, a primary determinant of cost. An unstable pound means unstable prices.
The final indicator is the domestic labour market. Watch the wage figures. Getting food to the table is a labour intensive business, involving millions of people in farming, manufacturing, logistics and retail. When their wages go up, so does the cost of the final product. Unlike a volatile commodity price, wages are sticky, meaning pay rises awarded one year become a permanent feature of a company’s cost base the next. A tight labour market, where businesses are competing to hire from a smaller pool of workers, forces them to offer higher pay and better conditions to attract and retain staff, a dynamic that creates a durable, long term upward pressure on the price of everything from a ready meal to a bag of apples. That pressure is now embedded. The monthly jobs data from the Office for National Statistics will tell you if it is getting stronger.
