But could increased demand make it harder for food banks to obtain essential supplies?
The Government wants households to keep three days' worth of emergency food supplies.
But could this well-intentioned advice have unintended consequences for Britain's food banks?
The UK Government's new Be Ready campaign, launched on 22 October 2026, encourages households to prepare for emergencies by keeping three days' worth of non-perishable food and bottled water at home.
The reasoning is understandable. Severe weather, flooding, power cuts and other emergencies could temporarily disrupt food supplies and essential services.
Being prepared makes sense.
However, here at That's Food and Drink, we believe there is another question that deserves serious consideration.
What happens to our food banks if millions of households suddenly start buying additional tins, packets and other long-life foods?
The Problem of Competing for the Same Products
Think about the foods that the Government recommends households should keep in reserve.
Tinned meat, fish, vegetables and other non-perishable products are among the suggested emergency supplies.
Now consider the foods that food banks regularly need.
Tinned vegetables, soups, beans, fish, meat and other long-life products are frequently requested because they are relatively inexpensive, easy to store and suitable for emergency food parcels.
There is considerable overlap.
If large numbers of shoppers begin purchasing additional supplies, could this place pressure on the availability of precisely those products food banks rely upon?
It is important to emphasise that there is currently no established evidence that the new campaign has caused widespread food bank shortages.
Nevertheless, the possibility deserves attention.
Remember What Happened During the Pandemic?
Many of us remember the extraordinary scenes during the early months of the COVID-19 pandemic.
Supermarket shelves were stripped of toilet rolls, pasta, rice, tinned foods and other essentials.
Some shoppers purchased considerably more than they needed, leaving others struggling to obtain basic groceries. And eventually much of these foodstuffs were binned as they had expired.
Nobody is suggesting that the Government's latest advice will necessarily produce a repeat performance.
Indeed, the official guidance specifically recommends building emergency supplies gradually rather than purchasing everything immediately.
But public behaviour is not always predictable.
If enough people interpret the advice as an urgent instruction to stockpile food, temporary shortages of popular products could become a possibility.
And food banks could find themselves competing with ordinary shoppers for limited supplies.
Food Banks Are Already Under Pressure
Britain's food banks continue to provide an essential lifeline for families and individuals experiencing financial hardship.
According to figures published by Trussell, food banks in its network distributed more than 2.6 million emergency food parcels during 2025.
Although this represented a reduction compared with 2024, demand remained substantially higher than before the pandemic.
These organisations depend upon a combination of public donations, supermarket collections, charitable support and purchased supplies.
Imagine a food bank volunteer visiting a supermarket to purchase essential provisions, only to discover that the cheaper tins of vegetables, beans or soup have sold out.
More expensive alternatives might be available, but purchasing those would mean stretching already limited funds.
Even modest increases in demand could create difficulties if they were concentrated on particular products or locations.
What About Families Who Cannot Afford Emergency Supplies?
There is another uncomfortable question.
How can someone who already struggles to afford today's dinner reasonably be expected to purchase three additional days' worth of food?
For financially secure households, buying an extra tin or two during the weekly shop may present little difficulty.
For people relying on food banks, however, even a small additional expense can be impossible.
The Government acknowledges that not everyone can follow every recommendation and says households should take the steps appropriate to their circumstances.
That is welcome.
Nevertheless, emergency preparedness must not become another area in which poorer households are left at a disadvantage.
Those least able to prepare independently may also be among those most vulnerable when an emergency occurs.
Could Supermarkets Help?
Supermarkets have an important role to play.
They could monitor demand for popular emergency foods and ensure that food bank collection points continue receiving appropriate supplies.
They might also consider additional donations of long-life products during the Government's campaign.
Manufacturers and wholesalers could help by working with food banks to maintain reliable supplies of essential products.
And shoppers themselves could make a difference.
If you are fortunate enough to afford an emergency food reserve, why not consider purchasing an additional item for your local food bank whenever you add something to your own supplies?
One tin for your emergency cupboard and another for someone who needs food today.
It is a simple idea, but one that could make a meaningful difference if enough households participated.
Should the Government Go Further?
The Government says its campaign has been developed with input from charities and organisations representing vulnerable people, including food bank users.
That is encouraging.
However, it would be sensible to monitor whether the campaign affects food bank donations, purchasing costs or access to essential products.
Local authorities, supermarkets and charitable organisations could work together to identify shortages before they become serious.
Emergency preparedness should strengthen communities, not inadvertently place additional pressure on those already struggling.
A Final Thought from That's Food and Drink
We support the principle of being prepared for emergencies.
Keeping a modest reserve of food and water is sensible advice, particularly as severe weather and other disruptions become increasingly important considerations.
But there is a difference between being prepared and forgetting about those who cannot afford to prepare.
The Government's three-day food plan could prove extremely valuable.
However, its success should not be measured solely by the number of households with well-stocked cupboards.
It should also be judged by how effectively the country protects its most vulnerable residents.
After all, what good is a national emergency food preparedness campaign if the people who most desperately need food find it harder to obtain?
Perhaps the message should be expanded.
Be ready for yourself. But help make sure your neighbours are ready, too.
And please, if you can afford to do so, remember your local food bank when purchasing those extra emergency supplies.
Because for some families, the food emergency isn't something that might happen in three days' time.
It is happening right now.
