In March 2025, the total business population of Buckinghamshire was approximately 30,535.

This represents a 2.1% decrease on the previous year, or a net decrease of 645 businesses, most of which was due to a decrease in the micro business population, falling 2.4% on last year. Nevertheless, Buckinghamshire maintains its status as having the highest concentration of micro businesses (<10 employees) of all enterprise regions in England, at 91%.

It should also be noted that this decrease in the number of businesses was significantly higher than the national and regional rates. The business population of England grew 0.35% in the year to March 2025, and the business population grew 0.14% in the South East. Therefore, Buckinghamshire’s high concentration of micro businesses may explain its decrease in business population relative to other areas with a lower micro business population.

There were gains in the population of larger businesses in Buckinghamshire, with a 1.2% growth in the number of medium sized businesses (50 to 249 employees).

By sector, there was a net decrease of 405 retail businesses in the year to March 2025, and a net decrease of 275 ‘office administrative and support activities’ businesses – these sectors contributed most to the net loss of 645 businesses in Buckinghamshire. However, there was a net gain of businesses in sectors such as electricity supply (+45 businesses), motor trades (+35) and film & TV production businesses (+30 businesses).
