British potatoes are feeling the heat!
What drought means for the 2026 potato harvest…
Potatoes are one of the most familiar ingredients in British foodservice. From chips and roasties to mash and jackets, they’re a staple we rarely think twice about.
But behind the humble potato, British growers have been navigating a difficult few years.
Back in our previous article from 2022, The Woes of Potatoes, we explored how extreme weather, flooding, storage issues, rising operational costs and a reduction in planted area were already putting significant pressure on the British potato industry.
Fast forward to 2026 and, unfortunately, growers are facing another challenging season. Only this time, rather than too much water, one of the biggest problems is not having enough of it.
What’s happening to the 2026 potato crop?
Prolonged heat and drought across much of England and Wales have created particularly difficult growing conditions this year.
Potatoes need a reliable supply of water, especially while the tubers beneath the soil are developing and increasing in size. When water becomes limited at this crucial stage, the crop can still grow, but yields can fall and the potatoes themselves may be smaller.
Industry reports are already warning of:
- Lower average yields
- Smaller tuber sizes
- Greater proportions of undersized potatoes
- More variation in quality between growing regions
Some growers have described 2026 as potentially one of the most difficult seasons seen in a generation.
Can’t growers just irrigate more?
Unfortunately, it’s not quite that simple.
As we explored in Understanding Water Use in Food Production, irrigation relies on having water available in the first place.
After such prolonged dry conditions, demand has been exceptionally high and even heavily irrigated crops have struggled to maintain their normal yield potential.
It’s a perfect example of why water availability matters so much to our food system. What happens to rainfall, rivers, reservoirs and soil moisture ultimately has an impact on what comes out of the ground.
What could this mean for foodservice…
Importantly, a smaller crop doesn’t automatically mean we’re going to run out of potatoes.
Instead, the impact is likely to be more nuanced.
We could see smaller potatoes, greater variation in quality, tighter availability within certain grades and specifications, and increased pressure on market pricing.
Specification is particularly important within foodservice. A potato destined for chips has different requirements to one being used for mash or a jacket potato. So, even when potatoes remain available, finding the right size, variety or specification can become more challenging.
Some flexibility around size and specification may therefore become increasingly valuable as the season progresses.
From too much water to too little!
Perhaps what’s most interesting about the current situation is just how much conditions have changed.
A few years ago, we were talking about growers struggling to lift potatoes from waterlogged fields. In 2026, we’re talking about crops struggling because of prolonged heat and a lack of water.
It demonstrates the increasingly complex conditions British growers are having to navigate and why building a resilient food supply chain is about much more than reacting to a single difficult harvest.
For now, it’s a case of pressure, not panic.
The full picture will become clearer as the main harvest progresses. We’ll continue working closely with our growers and suppliers, monitoring quality, availability and market movement and keeping our customers informed as the season develops.
Because understanding what’s happening in the field helps all of us make better decisions further down the supply chain.
