The UK government has confirmed plans to cut Civil Service running costs by 15% by the end of the decade, according to Chancellor Rachel Reeves.

This announcement follows an ongoing review into public sector financing aimed at achieving savings and enhancing government efficiency.

Reeves stated that these reductions would primarily target back office and administrative roles rather than direct frontline services.

Unions have expressed concerns about the potential effects of these cuts on public services, with estimates suggesting that around 10,000 jobs may be eliminated in the process.

This announcement is anticipated ahead of Reeves' Spring Statement scheduled for Wednesday, which is expected to detail spending reductions across various government departments.

In the coming days, Whitehall departments will receive directives from Cabinet Office Minister Pat McFadden, mandating savings exceeding £2 billion annually by the end of the decade.

Specific sectors such as human resources, policy advice, communications, and office management are reportedly among those facing significant funding reductions.

During an interview on the BBC's Sunday with Laura Kuenssberg program, Reeves highlighted that the size of the Civil Service had seen a significant increase during the Covid-19 pandemic, without returning to pre-pandemic levels.

"We are, by the end of this Parliament, making a commitment that we will cut the costs of running government by 15%," she stated, asserting that technological advancements and artificial intelligence could facilitate these reductions.

When questioned about the anticipated job losses within the civil service, the Chancellor acknowledged the possibility of approximately 10,000 positions being cut.

According to data from the Office for National Statistics, as of December 2024, the Civil Service employed an estimated 547,735 individuals, including temporary and casual workers.

Civil servants, who remain politically impartial while working in various government capacities, play crucial roles in policy development and public service provision, including areas such as benefits and rehabilitation services.

Union leaders have expressed skepticism regarding the distinction between back office cuts and those affecting frontline services.

Dave Penman, head of the FDA union representing senior civil servants, criticized the notion that such cuts could be made without impacting public service delivery.

Mike Clancy, leader of the Prospect union, echoed these sentiments, emphasizing the integral role civil servants play in assisting the public and executing government initiatives.

He cautioned that cuts across the board will significantly affect public service availability.

This latest initiative follows earlier commitments from the government, with McFadden previously announcing plans for "radical" Civil Service reform, which could include performance-based compensation for senior officials and incentives for underperforming staff to exit their roles.

Prime Minister Sir Keir Starmer also indicated an intention to reshape the operational structure of the state, aiming to alleviate bureaucratic burdens on civil servants.

The urgency for these cost-saving measures is heightened by disappointing economic growth, rising borrowing costs, and lower-than-expected tax revenues, which have placed additional pressure on the government to identify areas for financial savings.

Alongside these announcements, the government has revealed modifications to the benefits system, including stricter regulations on disability claims designed to achieve annual savings of £5 billion by 2030.

In her upcoming Spring Statement, Reeves signaled that she would not pursue tax increases or overall government budget expansions, asserting that the UK cannot rely on taxation and spending alone to enhance public services and living standards.

She maintains that public debt must decrease relative to the UK’s economic output by the end of the 2029/30 fiscal year.

While affirming that all departments have been instructed to prioritize their spending, she refrained from specifying the budget outcomes for individual departments, such as the Home Office or Ministry of Justice, which may be subject to cuts.

Each department has been tasked with ranking its expenditures from most to least crucial.

The Chancellor stressed the importance of investing more resources in areas deemed vital by constituents while minimizing funding for less critical areas.

In response to criticism from some Labour Party members regarding the potential re-emergence of austerity measures, Reeves referred to the substantial capital spending of £100 billion and £20 billion allocated to the NHS as evidence of a different fiscal approach compared to Conservative administrations over the past 14 years.

The Conservative shadow chancellor, Mel Stride, articulated concerns about Labour's management of the economy, arguing the current financial climate has made the UK more vulnerable.
