About the Farm Business Survey (FBS)
The Farm Business Survey (FBS) provides insight into the financial and physical performance of farm businesses in England. This page explains how the data is collected, what it represents, and how to interpret the results.
If you’re mainly here to explore charts and reports, you don’t need to read all of this detail — but it’s useful if you want to understand the methodology behind the survey.

About the survey
- The FBS is carried out every year through face-to-face interviews with farmers.
- The sample includes all farm types and all regions of England.
- Results are weighted so they represent the wider farming population (all farms with at least £21,000 of Standard Output).
Changes to sample size
- Around 1,780 farms were included in 2005/06.
- The largest sample was in 2010/11 with around 1,920 farms.
- Covid-19 restrictions reduced the 2019/20 sample to around 1,660 farms.
- In 2022/23, the sample was around 1,360 farms due to contractual changes.
- The latest year (2023/24) has a sample size of around 1,370 farms.
Accuracy and reliability
As the FBS is based on a sample rather than every farm in England, results include some uncertainty.
- We show 95% confidence intervals (error bars) to indicate the likely range for each result.
- Narrower intervals mean greater confidence in the result; results with wider intervals should be treated with more caution.
Understanding farm classifications
Accounting years
Results are based on farm accounts ending between 31 December and 30 April, giving consistency in harvest years and subsidies.
On average, the results cover a March to February fiscal year, with the most recent year shown ending in February 2024. Fiscal years are shown in YYYY/YY format, for example, the period of 1 March 2023 to 29 February 2024 is shown as 2023/24.
Farm size
Farms are grouped by labour requirement rather than land area:
- Spare/Part-time: Less than 1 full-time worker
- Small: 1 to 2 full-time workers
- Medium: 2 to 3 full-time workers
- Large: 3 to 5 full-time workers
- Very Large: 5 or more full-time workers
Farm types
Farms are classified based on what they mainly produce:
- Cereal
- General cropping
- Dairy
- Lowland grazing livestock
- LFA grazing livestock
- Pigs
- Poultry
- Horticulture
- Mixed
Standard Outputs (SOs)
- Since 2010/11, farm types have been classified using SOs — the average financial value of output per hectare or per animal.
- The Standard Output coefficients are updated every few years to reflect changes in agriculture.
- Before that, Standard Gross Margins (SGMs) were used.
Series breaks
There are breaks in the series at 2009/10, 2012/13, 2017/18 and 2022/23. Before 2009/10, Standard Gross Margins (SGM) were used to classify farms and to set the lower threshold for the survey. Since 2009/10, Standard Outputs have been used, which are based on a multi-year average. From 2009/10 to 2012/13, this was a 5-year average centred on 2007, hence this typology is called 2007SO. In 2017/18, the typology was updated to centre on 2010, and the 2010SO was used until 2017/18, at which point it was updated to centre on 2013. The current typology, based on a 5-year average centred on 2017, has been used since 2022/23.
Results for the series break years are calculated using both of the relevant typologies to allow for comparison.
SLR updates
Farm business size is classified using the Standard Labour Requirement, which represents the normal labour requirement for all the farm’s cropping and livestock activities under typical conditions. The previous update was in 2009, which was based on data from the 2004/05 to 2007/08 surveys. The most recent update was in 2024, which was based on data from the 2019/20 to 2022/23 surveys.
Revisions to 2022/23 & 2023/24 data
The phasing out of Direct Payments meant that the BPS variables used in the FBS calibration model are no longer available and, as a result, the model was updated in October 2025. As this was a methodological change, it caused a break in the time series. Instead of introducing a further break in 2024/25 two years after the 2017 Standard Output break, it was decided that the changes should be rolled back to the 2022/23 break. Therefore, the 2022/23 and 2023/24 results were revised. At the same time, the 2024 Standard Labour Requirement coefficients were introduced at the same series break.
