What are Estimates?

Estimates are the Government's spending plans which are presented to Parliament for approval every year. Government requests to Parliament for funds for departments are made in at least two and sometimes as many as four stages throughout the year in a process known as the 'Estimates Cycle'.

Consideration of Estimates happens at least once a year (between April and July, with respect to the Main Estimates), but more usually twice (between February-March with respect to the Supplementary Estimates). Select Committees can scrutinise each departmental Estimate, and MPs collectively debate and scrutinise them on Estimates days.

Once the Estimates have been debated, the House of Commons must consider a Supply motion. If the House approves the motion, then the Supply Resolution that results paves the way for a Supply and Appropriation Bill. Once this Bill is passed, it legally authorises the expenditure as set out in the Estimates.

Each Government department produces its own annual Estimate, and HM Treasury compiles and publishes them together in a single Estimates report for presentation to Parliament.

Treasury rules define the spending categories contained in the Estimates. Each departmental Estimate is made up of three key parts.

The ambit

This is the high-level description of what the money will be spent on in each department. If a department spends money outside the scope of the ‘ambit’ approved by Parliament, then that spending is unauthorised and therefore illegal. In such circumstances a department will require a Statement of Excess to provide retrospective approval for the spending.

Departmental expenditure limits (DELs)

These cover net spending, subject to the limits set out in the Spending Review process, in areas of activity that departments can generally forecast and over which they are therefore expected to exercise control. In each annual Estimate, the DELs are divided into two sub-categories:

Resource DEL, or current ‘day-to-day' spending: this includes, for example, costs for staff, purchasing goods and services, rents, maintenance and other administrative costs, depreciation and the sale of assets.
Capital DEL, or investment spending: this includes capital grants, loans, and the purchase, disposal or improvement of major assets.

Annually managed expenditure (AME)

This covers net spending in areas that are less predictable and therefore more difficult for departments to forecast and control:

Resource AME: this includes benefits, state pensions, and other welfare costs, as well as provision for liabilities.
Capital AME: this includes areas such as student loans.
Generally, departments cannot switch funds from DEL to AME, or from resource to capital spending categories, once the Estimate has been approved. However, within each category, a breakdown of proposed spending is provided, and this does not bind the government. Here, the government can vire money from one heading area to another, provided that neither the ambit nor the overall spending limit is breached.

News / 101 resolutions and a Finance Bill. How the Budget becomes law - Parliament Matters podcast, Episode 117

It’s Budget week, so we look at what happens after the Chancellor sits down and how the days announcements are converted into the Finance Bill. We speak to Lord Ricketts, Chair of the European Affairs Committee, about whether Parliament is prepared to scrutinise the “dynamic alignment” with EU laws that may emerge from the Government’s reset with Brussels. And we explore the latest twists in the assisted dying bill story, where a marathon battle is looming in the New Year after the Government allocated 10 additional Friday sittings for its scrutiny.

Publications / Budget 2025: Letter to Chief Whip Jonathan Reynolds MP calling for an ‘Amendment of the Law’ motion

The form of the first Ways and Means motion tabled after the Budget – either an Amendment of the Law motion or an Income Tax (Charge) motion – determines how much scope MPs have to propose amendments when the Budget is translated into the Finance Bill. An Amendment of the Law motion provides broader scope for amendment and was standard practice until it was unilaterally dropped by the then Government in 2017. We have written to the Chief Whip urging the restoration of this procedural practice so that MPs can properly fulfil their constitutional responsibility to scrutinise the nation’s finances and ensure that consideration of the Finance Bill is a genuinely political debate, not merely a technical exercise.

News / Is the House of Lords going slow on the assisted dying bill? - Parliament Matters podcast, Episode 116

In this episode we look at the latest Covid Inquiry report addressing the lack of parliamentary scrutiny during the pandemic and the need for a better system for emergency law-making. With the Budget approaching, we explore how the Commons Speaker, Sir Lindsay Hoyle MP, might discipline ministers who announce policies outside Parliament and why a little-known motion could restrict debate on the Finance Bill. Sir David Beamish assesses whether the flood of amendments to the assisted dying bill risks a filibuster and raises constitutional questions. Finally, we hear from Marsha de Cordova MP and Sandro Gozi MEP on their work to reset UK–EU relations through the Parliamentary Partnership Assembly. Please help us by completing our Listener Survey.
