Monitoring of GLA expenditure

This page is updated quarterly with the most recent published information about the Greater London Authority's expenditure, covering both revenue and capital expenditure.

This information is first published in the GLA's quarterly financial monitoring reports, with key information compiled on this page by the London Assembly Research Unit.

The charts are based on the most recent quarterly report, and present 'year to date' figures for the current financial year for each GLA directorate. Prior to the publication of the first quarterly report of the year, charts will display outturn figures for the previous year.

These charts display actual revenue expenditure in the current financial year, to date. The first chart displays the gross (total) expenditure for each GLA directorate (excluding the Assembly Secretariat). The second chart displays net expenditure, which is the gross expenditure minus income received (for instance from grants).

This chart displays variances between actual revenue expenditure and the revenue budget for each GLA directorate. Budget figures are the revised budgets as set out in the GLA's quarterly monitoring reports. 

This chart displays actual capital expenditure in the current financial year, to date, for each directorate. Directorates without capital expenditure in the year to date are not included in the chart.

This chart displays variances between actual capital expenditure and the capital budget for each GLA directorate. Directorates without capital expenditure in the year to date are not included in the chart. Budget figures are the revised budgets as set out in the GLA's quarterly monitoring reports. 

Expenditure to support the building of new homes under the Affordable Homes Programme is classed as capital expenditure by the GLA.

Prior to 2025-26, the GLA also published financial performance figures by budget theme as well as by directorate. This information is no longer provided in quarterly financial monitoring reports.

From 2025-26, the GLA moved to a 13-period approach to financial reporting, in which financial the year is divided into 13 'periods' of four weeks. Previously, the year was divided into four 'quarters' of three calendar months.

For the calculation of budget variances, the GLA uses 'revised budget' figures, which are published in each quarterly financial monitoring report, rather than the original budget agreed by the Mayor and London Assembly before the start of each financial year. 

The GLA's quarterly reports, along with those of GLA Functional Bodies, are submitted to the London Assembly Budget & Performance Committee. The Committee also scrutinises the Mayor's annual budget proposals. Read more about the work of the Budget & Performance Committee.

The London Assembly Research Unit has published analysis of the GLA's expenditure on environmental programmes. This includes information the GLA Group's climate budgeting and the Mayor's environmental mandates. 

The Research Unit has also published analysis of the Mayor's budget proposals for expenditure on missions and themes over recent years.

The GLA's quarterly financial monitoring reports and the Mayor's annual budget proposals are available on the GLA website.
