Procurement statistics: a short guide

Overall figures

There are two main sources for data on how much the public sector is spending on procurement in total across the UK.

The Whole of Government Accounts

The Treasury’s Whole of Government Accounts is possibly the most useful source overall for looking at how much the public sector buys from the private sector. 

The latest data is currently for 2019/20, when £295.5 billion was spent on procurement – about a third of public sector spending (32%).

Public Spending Statistics

The Treasury’s Public Spending Statistics and Public Expenditure Statistical Analyses (PESA) give more recent figures but include the procurement of goods and services by one public sector body from another.

According to this source, gross spending on public sector procurement was £379 billion in 2021/22 across the UK.

There was an increase by £24 billion or 7% between 2020/21 and 2021/22. 

Published budgets for 2022/23-2024/25 suggest procurement spending staying at around the higher levels seen in 2021/22.  Note that these figures are based on government budgets which do not cover the full public sector, unlike the figures quoted above.

Other useful sources

Other useful sources include for procurement statistics include:

• Cabinet Office figures on Central government spend with SMEs

• European Commission studies on procurement with foreign suppliers – the most recent is Study on the measurement of cross-border penetration in the EU public procurement market

• Figures derived from published public sector transparency data, for example from Contracts Finder. Organisations analysing this data include Spend Network and Tussell

• The National Audit Office
