Vertical Farming in the UK: Industry Overview


Vertical farming has gained popularity in the UK in recent years as vertical farms are being set up in cities across the country. Private and government funds are widely supporting vertical farming across the country, aiming to promote and integrate this approach into urban centers. For instance, in an urban environment, such as London vertical farms can guarantee a constant fresh supply to its population at any time.

Traditional agriculture in the UK often makes excessive use of fertilizers and pesticides, and it continuously suffers from labor shortages. As a result, vertical farming and urban agriculture are rapidly integrating into the skyline of many British cities.

A growing number of vertical farms and vertical farming technology companies are currently operating in British cities, where they deliver fresh, pest-free produce to local supermarkets and consumers. Continue reading to learn more about some of the most innovative vertical farms in the UK, the size of the UK vertical farming market, and the research and education opportunities available to anyone who has an interest in vertical farming.

Vertical Farming Conditions in the UK

Agriculture in the United Kingdom is highly automated and efficient, and it produces about 64% of the total amount of food consumed in the country. However, climate change, Brexit, workforce shortages, and other environmental challenges are putting increased pressure on farmers and the agricultural sector in the UK.

The traditional agricultural sector occupies about 69% of the country’s land area, with most farmland located in the East of England. As of 2020, 83.9% of the UK’s population lives in urban areas. There are about 55.91 million urban dwellers and only 10.93 million rural residents. Vertical farms have a great potential to feed the increasingly urban population of the UK while taking advantage of vacant buildings, factories, and other community dead spaces in the cities. Furthermore, urban dwellers will have easy access to highly nutritious and carbon-neutral fresh produce within 24 hours of harvesting.

The excessive use of fertilizers and pesticides in agricultural practices is a constant concern for British agriculture, as it increases the risk of soil degradation and water pollution caused by agriculture runoff. By recycling water and harvesting rainwater, many UK vertical farms have significantly reduced their water consumption. Additionally, they use hydroponics and aeroponics growing methods, which can reduce water usage within vertical systems by as much as 98%.

But the most concerning problem for the British agricultural sector is the lack of farmworkers, such as harvesters. In the UK, 99% of agricultural workers are from eastern European countries like Bulgaria and Romania, while only 1% are domestic workers. The aftermath of Brexit made the situation for UK farmers even worse, as new regulations and restrictions were introduced regarding the right to work in the country. Consequently, agriculture workers were in short supply, which often resulted in catastrophic agriculture losses for the British farmers.

Highly automated vertical farms provide an excellent solution to the lack of agriculture workers in the UK since plants are grown under controlled conditions, where every aspect of their growth is controlled by sensors, and only a small number of highly specialized employees are required to run and operate the farm. Furthermore, the introduction of robotic arms in vertical farming has automated labor-intensive jobs such as harvesting, which no longer requires a great number of farmworkers. For example, the Jones Food Company operates 365 days per year while employing just six workers.

In addition, The Fresh Plaza reported that in 2020, UK farmers produced fewer vegetables and fresh foods, resulting in an increase in imports. Crops such as lettuce, onions, cucumbers, and bell peppers are mainly imported from countries such as France, Germany, the Netherlands, Italy, and Belgium. Brexit, however, made the trade with these countries more difficult and paperwork-intensive. Growing vegetables vertically could reduce Britain’s dependence on foreign fresh vegetable supplies. Growing leafy greens, such as lettuce, basil, and salads vertically allows growers to achieve maximum production on limited land. Additionally, vertical farms produce throughout the year regardless of the outdoor weather conditions.
