Record Heat Slams UK Dairy Production

Core Event: Summer Heat Cuts Milk Output by 240 Million Litres
During the exceptionally hot summer of 2026, dairy farms in England and Wales delivered roughly 240 million litres of milk less than expected, according to the Energy and Climate Intelligence Unit. The shortfall equals four fewer days of milk supply between May and August, based on daily delivery records.
Background & Context
2026 saw the United Kingdom experience its hottest summer on record, with five intense heatwaves and prolonged dry spells that triggered drought declarations and hose-pipe bans. Poor grazing and heat stress forced many farms to shift cattle onto winter feed earlier than usual.
Data & Statistics
- £83 million worth of milk was lost, calculated from the volume shortfall.
- 87 days between May and August fell below expected output versus the 2008-2025 benchmark.
- The deficit widened as the season progressed, affecting 25 days in June and every day of July and August.
- The UK milking herd hit a record low in 2026, yet total annual production could still approach near-record levels because farms built up a cushion earlier in the year.
- As of September 4, grass growth for the season stood at 86 % of the 2019-2024 average, enough to feed the national cattle herd for two months.
On-the-Ground Reports
- Debbie Wilkins, a dairy and beef farmer in Gloucestershire, called the season “a difficult summer,” noting that her herd was fed full winter rations in midsummer and kept indoors to mitigate heat stress.
- Rather Grice, a dairy farmer in Leicestershire, described a “double whammy” of rising costs and low milk prices, forcing indoor housing from mid-August until grass regrew.
Both farmers highlighted the added cost of indoor housing, silage production and labour, which compounded the loss of milk output.
Official Statements & Responses
The ECIU senior analyst, Tom Cantillon, warned that the shrinking UK dairy herd makes the sector increasingly vulnerable to climate-related shocks. He argued that without substantial climate-resilience measures—such as increased shade, tree planting and water infrastructure—future heat events could further erode farm incomes. Cantillon noted that the current loss is unlikely to affect national milk supplies or prices in the short term but underscores growing financial pressure on producers.
Verbatim Quotes
- “For months, UK dairy farms produced below a normal summer, and by August the scale of the impact was regularly worse than anything seen in 18 years.” — Tom Cantillon, ECIU senior analyst
- “This has been a difficult summer.” — Debbie Wilkins
What’s Next
The ECIU recommends that policymakers and industry bodies support climate-adaptation strategies for dairy farms, including incentives for on-farm shade structures and diversified forage options. No specific legislative timetable has been announced, but proactive measures are deemed essential to mitigate the impact of increasingly frequent heatwaves.
