Intensive farming in the UK, by numbers

A major Bureau investigation has revealed the changing face of British farming. The number of intensive farms in the UK has risen by a quarter since 2011, with many so big they fit the definition of a US mega-farm. 

Below you can find all the data we obtained, analysed per country, county and type of livestock. It contains information on the five companies controlling nearly all poultry meat production in the UK. You will also find information on which of these companies operate mega-farms, and the supermarkets they supply.

The Environment Agency - and its regional counterparts in Northern Ireland, Scotland and Wales - classify livestock farms as "intensive" if they have capacity for housing at least 40,000 poultry birds or 2,000 pigs grown for meat or 750 breeding pigs (sows).

These "intensive" farms each require a permit to operate that is issued by the relevant environment agency. Very large free range farms also need this licence but there are far fewer of them. This contains details of the farm operator, the number of livestock permitted to be housed and a detailed set of conditions that must be met for the farm to operate. 

Existing farms can be issued with a new permit if changes to the original conditions are proposed- such as if a farm wants to increase the number of livestock it houses - or if it changes owners.

How farms have intensified over time, and where

Most intensive farms in the UK are poultry farms, our analysis has shown. They make up 86% of the total numbers of permit-holding farms.

Between 2011 and 2017 there was a 27% increase in permit-holding poultry farms across the UK.

Overall, the number of large intensive farms - pig and poultry - with an Environment Agency permit in the UK is currently 1,674 - an increase of 26% since 2011 when there were 1,332 facilities requiring a permit. The figures are as of July 2017 for Scotland, March 2017 for England, and Northern Ireland and January 2016 for Wales.

Some areas of the UK saw particularly sharp rises: in Northern Ireland the number of pig and poultry factory farms has increased by 68% from 154 in 2011 to 259 in 2017.

The Bureau also calculated which areas in England had the most permit-holding intensive farms. This was broken down by operational area – which is the part of the country each local Environment Agency department covers.

Shropshire, Herefordshire, Worcestershire and Gloucestershire have the most intensive farms with a total of 208. Essex, Norfolk and Suffolk have the second highest total 176, with Yorkshire next with 168. This was compared with Solent and the South Downs – which have 20. Kent and South London have 8 and Hertfordshire and North London 3.

Nearly 800 mega-farms

Our investigation has also shown the UK is now home to at least 789 mega-farms or what the US calls CAFOs (Concentrated Animal Feeding Operations).

To meet the definition of a Cafo, a facility must have at least 125,000 broilers (chickens raised for meat), or 82,000 layers (hens which produce eggs) or pullets (chickens used for breeding),  or 2,500 pigs, 700 dairy cattle or 1,000 beef cattle. 

The majority of the UK mega-farms - 575 - are poultry, with 190 pig, 21 dairy and 3 beef units.

Seven of the 10 largest poultry farms - producing meat or eggs or both - in the UK have the capacity to house more than one million birds. The biggest two farms are able to hold 1.7 million and 1.4 million birds respectively. The biggest pig farm is able to hold 23,000 pigs, while the largest cattle farm - in Lincolnshire - can house approximately 3,000 cattle.

Supermarket links

The Bureau's investigation also established that many UK supermarkets and fast food chains buy from companies operating such US-style mega-farms, including Tesco, Sainsbury’s, Co-op, M&S, Morrisons, Asda, McDonalds and Nando's.

  • Poultry supplier Hook 2 Sisters is a joint venture between PD Hook and 2 Sisters Food Group. It operates farms that supply birds to 2 Sisters Food Group whose customers include Tesco, Morrison’s, Sainsbury’s, M&S, and Asda. Data shows that Hook 2 Sisters operates 37 Cafo-sized facilities across the UK.   
  • Faccenda Foods, which supplies poultry to Asda and Nando's, among others, operates 26 Cafos in the UK. Moy Park, which supplies Asda, McDonalds and Burger King, has 19 Cafos across the country.  
  • JSR Farms, which rears pigs, says it is in partnership with Sainsbury’s and Morrisons, and operates 4 Cafos, according to our analysis. J C Lister, another major pig producer, operates 2 Cafos and reportedly has supplied Tesco, Co-op and Aldi.
  • A large Cafo-sized farm called Pawton Dairy supplies milk to Arla. Arla butter and cheese are sold in Co-Op.

    Is there any way of pushing for honest food packaging so that people know the conditions these animals were raised in before they buy the product?

  • Rren

    Nope. And the worst is that you pay 10 times more for the meat in supermarket than it comes out of the farm!

  • Andrew Child

    How are DEFRA and the RSPCA addressing the disgusting animal cruelty being perpetuated within these farming companies?

  • Paul Toms

    How come there hasn't been an answer to the above question?

    Isn't it about time that the government made farming right in this country?
    Why are there US companies monopolising farming in the UK?
    Seeing as there is a global requirement for everyone to only eat meat once a week to help combat global warming, surely limitation for the production of meat products is required.
    All animals should be free range and ok so that would triple their cost but that's fine because that would have the desired effect of consumption reduction. This kind of approach is long overdue so when's it going to happen? Hasn't anyone seen what the consequences will be over the coming years? I think government are blind.

  • Jane Clan

    Why is intensive farming still a thing? As humans, we have achieved so much. Yet still, we adopt cruel methods that simply aren't necessary... there are many more ways we can mass produce animals - SURELY WE CAN MASS PRODUCE ANIMALS IN A CLEANER, NICER, FRIENDLIER WAY???

  • Amanda Lyons

    Im trying to find out how many Intensive Farms there are in Scotland. With the emergence of COVID 19 and the threat of zoonotic disease being born from any of these Factory Farms - I would love to get more current data.

  • Mojomonkey

    "Cruel conditions". The odd zoomed in snapshot of some birds in a shed and the general public get on their high horse. How predictable. These farms are routinely audited and checked, have vet visits on the regular and stick to very strict welfare laws. 99.9 percent of farm staff do their absolute utmost to give these animals the best life possible. Angers me greatly when people with no knowledge of the day to day goings on believe every negative comment from the media.
