UK Food Security: How Much Food Does Britain Produce?

Britain produces much of the food it eats, but it still relies heavily on imports. The answer to UK food security is not a single percentage, because the result changes depending on whether the calculation includes every food product or only foods that can be grown here.

Defra’s latest figures show a country that is capable of feeding itself in several key areas, yet remains exposed to energy costs, poor harvests, transport disruption and overseas supply chains. The figures also raise a political question: should Britain accept import dependence, or make domestic production a bigger national priority?

What does UK food security measure?

The main statistic is called the food production-to-supply ratio. It compares the value of raw food produced on British farms with the value of raw food available for people to eat.

That definition matters. The UK cannot grow bananas, coffee or many other products at commercial scale because of its climate. Those imports lower the overall figure, even though importing them is unavoidable.

Defra therefore publishes two related measures:

• All food includes every food category consumed in the UK.
• Indigenous-type food includes food that could be grown or produced commercially in Britain.

The latest confirmed figures in the UK Food Security Report 2024 put the UK’s production-to-supply ratio at 62% for all food in 2023. For indigenous-type food, the figure was 75%.

Defra’s 2024 agriculture estimates lifted those figures to 65% for all food and 77% for indigenous-type food. The 2024 numbers are estimates, so the 2023 figures remain the clearest benchmark for comparing recent performance.

The figures don’t mean that 62% of every item on a supermarket shelf is British. They measure value across broad food categories. A fall in the price of British grain, for example, can affect the ratio even when farmers produce a similar volume.

Britain’s food security depends on production, affordability and reliable access. Self-sufficiency is only one part of that picture.

How much food does the UK produce?

The short answer is that Britain produces around two-thirds of all food consumed by value, or roughly three-quarters of the food it could produce domestically.

Measure	2023	2024 estimate
All food	62%	65%
Indigenous-type food	75%	77%

The long-term record shows why the issue attracts concern. The all-food ratio reached about 78% in 1984, before falling during the following decades. It stood at roughly 62% in 2010, then moved around 60% to 62% in recent years.

That decline doesn’t mean British agriculture has stopped producing food. It reflects changes in diets, farming costs, land use, trade, prices and the growth of international food supply chains.

Some domestic sectors remain strong. Britain has substantial dairy, livestock, cereal and poultry production. However, the country is much more dependent on imports for certain fruit and vegetables. The National Farmers’ Union reports that fresh vegetable self-sufficiency fell to 53% in 2023, the lowest level recorded since its series began in 1988.

The gap is important because fresh produce is not always easy to replace quickly. A poor harvest in Britain can be followed by higher prices when other countries also face drought, flooding or transport problems.

Food production also supports a large part of the rural economy. Defra’s agriculture dashboard says UK agriculture provides 62% of the food people eat, employs almost half a million people and generated £7.2 billion in Total Income from Farming in 2023.

Why self-sufficiency varies between foods

A national average can hide major differences between individual products. Britain may produce a high share of one food while importing most of another.

Climate is the first factor. British farms can produce wheat, barley, potatoes, milk, beef, lamb and many vegetables. They cannot produce enough citrus fruit, rice, tea or coffee for normal consumption.

Seasonality also affects the figures. British growers supply more vegetables during the warmer months, while retailers depend on imports during winter. Greenhouses can extend the growing season, but heating them requires substantial energy.

Costs have a direct effect on output. Fertiliser, animal feed, fuel, machinery, electricity and labour all influence whether a farm can remain profitable. When costs rise faster than the price paid to producers, some businesses reduce production or leave farming.

Land use creates another pressure. Farms compete with housing, roads, commercial development, woodland and renewable energy projects. Reform UK argues that poorly planned net zero policies have put productive farmland under pressure, including through solar farms and wind developments. Its farming policy calls for fewer paperwork burdens, fairer prices and stronger support for domestic producers.

Those claims form part of a wider political argument about how Britain should balance energy generation, climate policy and food production. Renewable infrastructure can provide power, but decisions about its location affect the amount and quality of land available for farming.

The Agriculture and Horticulture Development Board’s analysis of UK food security also separates food availability from the strength of the supply chain. A country may grow enough food in theory, yet still face problems if farmers lack affordable inputs or retailers cannot move products efficiently.

Why imports still matter to Britain’s food supply

Imports are not automatically a weakness. They give consumers access to foods that Britain cannot grow in sufficient quantities, while allowing British farmers to export products where they are competitive.

The risk comes when too much dependence builds in a small number of places or supply routes. A blocked shipping lane, poor harvest, disease outbreak, trade dispute or sudden energy shock can affect several countries at once.

Britain imports food, animal feed, fertiliser, seeds, machinery and packaging. These connections make food production more efficient, but they also create points of pressure. A farm may have British land and workers, yet still depend on imported fuel or fertiliser.

The same applies to supermarkets. Shops usually hold limited stocks of fresh food because customers expect regular deliveries. That keeps prices and waste under control during normal conditions, but it leaves little room when transport or production fails.

Food security also includes household finances. Defra’s United Kingdom Food Security Digest 2025 says at least 90% of households have been food secure in each of the five years measured since the financial year ending in 2020. That still leaves around one in ten households facing some level of food insecurity.

A plentiful national supply does not guarantee that every family can afford a healthy diet. Wages, rent, energy bills, transport costs and food prices all affect access. Stronger domestic production can help reduce exposure to overseas disruption, but it cannot solve household poverty on its own.

Energy costs and farmers are part of the same debate

Food security begins on farms, but farming depends on affordable energy. Tractors need diesel, grain drying needs heat, milking equipment needs electricity, and protected crops often need controlled temperatures.

High energy costs raise the price of almost every stage of production. They also affect fertiliser, glasshouse growing, food processing, cold storage and distribution. When British production becomes more expensive than imported alternatives, retailers face pressure to buy abroad.

Reform UK’s policy position links energy security with food security. The party says Britain should expand domestic energy production, reduce policies that push bills higher and give farmers more freedom to operate. Its wider argument is that lower energy costs would help households, businesses and food producers.

The practical challenge is balancing cheaper energy with reliable supply and environmental responsibilities. Farmers need clear rules, stable investment conditions and access to power. Sudden policy changes make it harder to plan for livestock buildings, irrigation, greenhouses or machinery.

A stronger approach would also protect fertile farmland, improve water storage, support British horticulture and reduce unnecessary administration. Those measures would not make Britain entirely self-sufficient, but they could raise production in areas where the country is already capable of doing more.

What would stronger UK food security require?

The first step is to measure food security honestly. A headline figure should always state whether it covers all food or only indigenous-type food. Without that distinction, public debate quickly becomes confused.

The next step is to identify the foods and inputs where Britain is most exposed. Fresh vegetables deserve attention because the domestic share is low. Fertiliser, animal feed, fuel and seasonal labour also matter because shortages can reduce output even when land remains available.

Government policy has a major influence on the result. The Reform UK policy platform puts farmers, domestic energy and national self-reliance within a wider programme focused on reducing regulation and prioritising British interests.

For its supporters, food security fits a broader belief that essential national capacity should not be surrendered without a clear reason. That argument needs practical measures, not slogans: reliable energy, fair farm-gate prices, sensible planning decisions, skilled workers and trade relationships that keep imports available when domestic production falls short.

Conclusion

Britain produces about 65% of all food by value, based on Defra’s 2024 estimate, and around 77% of the food it can grow domestically. Those figures show real agricultural strength, but they also reveal dependence on imports, energy and international supply chains.

The central question for UK food security is not whether Britain can produce every food it consumes. It is whether the country has enough domestic capacity, dependable trade and affordable access to keep food on shelves when conditions change.

Backing farmers and protecting productive land would strengthen that capacity. Britain cannot remove every risk, but it can decide how much control it wants over the food that feeds its people.
