Combined Online Information System

The Combined Online Information System (COINS) is the database for UK Government expenditure. The data is used to produce expenditure data in the Budget report; Supply Estimates; Public Expenditure Statistical Analyses (PESA); Whole of Government Accounts (WGA); the monthly Public Sector Finance Releases. It is also used by the ONS for other National Statistics releases.

At the release of the COINS raw data in June 2010, the government committed to publishing additional datasets utilising the COINS raw data. In August 2010 we published the first of these datasets showing in year time series data. The in-year dataset is updated quarterly and will be published in the links below.

The aim of these datasets is to make key parts of the COINS data accessible, manageable and comprehensible to the wider public, whilst maintaining a low level of aggregation. Datasets for the time series and for the outturn to budget comparison can assist in interpreting the COINS raw data. At the same time users will be able to drill down behind previously released high level aggregates.
