UK Food Prices Soar: Climate Crisis and Tax Pressures Are Rewriting Your Shopping Basket

According to the latest data from the British Retail Consortium (BRC), annual food inflation in June rose to 3.7%, up from 2.8% in May – the largest monthly increase in nearly a year.
That means you may now be spending an extra £5–10 per week on food – equivalent to the cost of a coffee or half a dozen eggs. Even more concerning is that this surge is not a temporary blip but a warning sign of the sustained dual impact of the climate crisis and shifting tax policy on the agricultural system.
The price hike breakdown: ‘climate tax’ and ‘policy tax’ on the dinner table
Vegetable and fruit crisis: Potato prices have risen by 20% year-on-year, carrots by 38%, and olive oil by 40% due to disease outbreaks affecting olive trees in Italy. The Fresh Produce Consortium notes that 65% of the UK's fresh fruit and vegetables are imported. Severe droughts in southern Europe are driving up supply chain costs.
The chocolate crisis: West Africa – which produces three-quarters of the world’s cocoa – has been hit by drought, heavy rains, and crop disease, slashing production and nearly doubling some chocolate prices.
Staple food alert: Wheat and barley are expected to yield 15–20% less due to spring droughts. A new round of price increases is anticipated for everyday essentials like bread and pasta.
Tax and National Insurance: The Hidden Forces Behind Price Rises
1. The 'cost chain' of labour
From April 2025, the UK government increased the employer National Insurance rate from 13.8% to 15%, while slashing the threshold from £9,100 to £5,000. Research by the British Chambers of Commerce (BCC) shows that this change has raised average staffing costs in the retail sector by 4.2%, with supermarkets and food processors most affected.
M&S and Sainsbury’s are reportedly incurring nearly £200 million in additional annual staffing costs – equivalent to £1.80 more in labour cost for every £100 of goods sold.
These costs are being passed directly to consumers: Tesco raised the price of its own-brand bread by 5p in June, while Asda increased average dairy prices by 3.2%. The Food and Drink Federation (FDF) estimates that for every one percentage point increase in employer National Insurance, food prices rise by 0.7%.
2. Farming’s ‘cost trap’
Figures from the National Farmers' Union (NFU) show that average UK farm profit margins have dropped from 6.8% five years ago to 3.1% in 2025. 42% of small to medium farms say they have ‘no choice but to raise prices to stay afloat’. This has contributed to a 9.3% year-on-year rise in the price of locally grown vegetables – significantly above the overall food inflation rate.
3. Supply chain ‘butterfly effect’
While the UK government has temporarily removed tariffs on 89 imported food items (including pasta and fruit juice), adjustments to the VAT system continue to increase costs. A less visible impact comes from cross-border transport: haulage firms have raised shipping fees by £8 per tonne due to higher National Insurance costs for drivers. This has raised the import cost of Spanish citrus fruit by 6.7%, which is now being reflected on supermarket price tags.
4. Consumer ‘stress test’
Households are now being squeezed by shrinking income and rising expenses. The freezing of personal tax thresholds has effectively increased the real tax burden, while rising food prices are acting as a form of hidden wage cut.
The Resolution Foundation think tank estimates that a typical dual-income household earning £40,000 will see its disposable income fall by £1,200 in 2025 compared to 2023. Of that drop, 38% is attributed to higher food costs.
This pressure is especially acute among low-income families: those earning under £20,000 now spend 16.2% of their income on food, up from 14%. According to Kantar, this has led to an 8% fall in fresh produce purchases and a shift toward cheaper processed foods.
Climate Under the Microscope: Extreme Weather and Policy Pressure Combine
Crop Death Spiral
The Met Office reports that spring 2025 saw the driest and hottest conditions in a century, with soil moisture reaching record lows. With rising tax pressure, farmers lack the resources to invest in water-saving irrigation systems, worsening crop failures. In eastern England, a key potato-growing region, reduced water supply led to a 23% drop in yields. Combined with rising labour costs, retail potato prices have surged 20% year-on-year.
Agricultural Vicious Cycle
To cope with combined climate and tax stress, 15% of UK farms have reduced organic planting in favour of higher-yield crops that require more fertiliser. This has pushed up organic food prices by 12.8% – twice the rate of regular food inflation. Experts warn that this short-term move could accelerate soil degradation and pose long-term risks to crop yields.
Global Shockwaves
Brazil has raised its soybean export tax from 8% to 12% to fund rainforest conservation efforts. This has increased feed costs for UK livestock farmers by 11%, contributing to meat price hikes. Chicken breast prices in UK supermarkets have risen for six consecutive months, with a total increase of 14.2%.
Who is paying the price? The double hit on low-income families
Spending Gap
Rising food prices now account for a significantly larger share of spending in low-income households – up to 1.5 times that of higher-income households. Following a 4.1% food inflation rate in May, sales of supermarket own-brand items rose 12% year-on-year, while fresh produce purchases fell 8%.
Invisible Hunger
The UN reports that over 700 million people globally faced hunger in 2023, and this figure is expected to climb in 2025. In the UK, food bank usage has exceeded one million for three consecutive years. Meanwhile, increased tax revenue demands have led the government to cut its food aid budget by 12%.
When climate crisis meets tax reform, food price inflation in the UK is no longer the result of a single factor. Each rise on a supermarket shelf reflects the complex interplay between ecological strain and economic policy.
For consumers, understanding how these forces work can help with smarter budgeting, tax planning and sustainable choices. Ultimately, the key to solving this crisis lies not only with policymakers but also with every household’s dinner table.
