22-26 Whitehall has 825 desk work settings. The site is used by multiple Government departments, and official figures have not yet been updated following the creation of the Department for Business, Innovation, Science and Trade.

On 30 June 2026, 22-26 Whitehall had 998 active DSIT civil servants as their contracted office location.

I am advised by the Department that, based on the most recent occupancy and space-planning data available, there are 3,206 desks within the King Charles Street building.

Desk numbers are kept under regular review and may increase or decrease over time to reflect operational requirements, estate reconfiguration, and changing business needs. As such, the figure provided represents the most accurate position at the time of the latest assessment rather than a permanent fixed total.

In terms of headcount, the number of civil servants assigned to the offices of the Foreign, Commonwealth and Development Office at King Charles Street is 4,129.

As of 30th June 2026, there are: 1) 1,261 desks; and, 2) 2,180 civil servants assigned to the Department for Transport office at 33 Horseferry Road.

It has been the practice of this and successive governments not to comment, on grounds of both national security and staff safety, on the physical capacity or staffing numbers for individual buildings of the government estate.

Mr Brown has taken up an unpaid role as a Special Reviewer. In this role, he has been supporting the Prime Minister by progressing existing government workstreams.

The civil servants working with Mr Brown are already working full-time within those policy areas.

The department regularly reviews its estate to ensure it meets the needs of customers and colleagues, supports service delivery and represents value for money for the taxpayer. The Workplace Transformation Programme began in 2021 to ensure the department has an estate that is the right size and shape to meet current and future business needs. It is aligned to the department and wider government’s ambition of creating a smaller, better and greener public estate.

While we do not undertake ‘regional occupancy modelling’, we seek to maintain a broad geographic distribution of offices across Great Britain. However, to ensure offices remain viable and the estate is aligned to operational requirements, the size and distribution of the DWP estate may change over time. Decisions on individual offices are not taken in isolation. When making decisions about the estate, the programme assesses the impact of proposed changes on:

• customer service delivery and operational resilience – working with business leaders to ensure no disruption to customers as a result of estate changes
• value for money – ensuring the department is only paying for the estate it needs
• office capacity and utilisation – our office capacity across the network is larger than our headcount by about a third
• building quality, sustainability and size – the programme seeks to move away from low quality, inefficient, smaller sites to fewer, better, larger and more sustainable buildings
• workforce requirements – ensuring the location and design of our buildings meets the needs of our workforce
• staffing levels – estate rationalisation activity is not delivered with the aim of reducing the department’s headcount, and our first priority is to retain, retrain or redeploy impacted colleagues.
• lease events

The programme recently announced consolidation activity impacting nine of our office buildings:

• Blackpool Peel Park
• Derby Holborn House
• Glasgow Northgate
• Halifax Dean Clough Mills
• Hyde Beech House
• Liverpool Belle Vale
• Motherwell Johnstone House
• Sunderland Wear View House
• Torquay Cotswold House

The department continually reviews our entire estate to ensure it is aligned to local requirements. Whenever the department makes decisions about our estate, our priority is to communicate with our colleagues first, followed by impacted MPs and members of the devolved administrations where applicable.

Further information will continue to be published through these established processes and in accordance with commercial and operational considerations.

The programme’s business case is regularly scrutinised to assess whether it measures up to the standards set out in Managing Public Money. A recent summary of the key points from the Accounting Officer’s Assessment of the Workplace Transformation Programme was made available to Parliament in April 2026 and can be found on GOV.UK. The Department does not routinely publish information where doing so could prejudice its commercial position, ongoing estate planning activity or the delivery of value for money for the taxpayer.

For security reasons we do not comment on the specific location of individual’s offices. The Prime Minister’s Special Reviewer on Global Finance and Cooperation has access to appropriate office space within the Cabinet Office’s existing footprint if required.

The Prime Minister’s Special Reviewer on Global Finance and Cooperation has access to appropriate office space on the government estate. He receives support from existing teams as part of their enduring policy responsibilities, as and when required.

The monthly total number of employees in the HQ building is calculated by using the number of unique individual security pass swipes recorded by the access control system.

The monthly capacity of the HQ building in each of those months for 22 Whitehall is calculated by the number of available individual IT-enabled work settings in the building and multiplying that by the number of working days in each month.

The HQ office attendance figures on GOV.UK are calculated using the total number of unique individual security pass swipes recorded by the access control system in the quarter as a percentage of the total number of available individual IT-enabled work settings in the building in each month of the quarter.

The Cabinet Office Second Headquarters is based in the Government Hub at 1 Atlantic Square, Glasgow.

The Cabinet Office's Second Headquarters serves as a key regional base, accommodating over 700 Cabinet Office staff.

It has been the practice of successive governments not to comment, on grounds of both national security and staff safety, on the physical capacity or staffing numbers for individual buildings of the government estate.

Civil Servants in 22 Whitehall book an unspecified space on a specific floor.

The numeric figures for July to September 2025 are:

The figures include the adjoining building 26 Whitehall, which was gradually opened and occupied in phases across July, August and September. From October onwards, capacity figures include 26 Whitehall. Monthly totals also include colleagues using meeting rooms and other shared building facilities, which are not included in capacity figures.

The Crown Court operates from 84 buildings across England and Wales, with a core estate of over 500 courtrooms. Most are jury-enabled and suitable for trials, with the remainder supporting other judicial work, such as interlocutory hearings. The wider HMCTS estate—including magistrates’, civil, family, and tribunal rooms —can also be used for Crown Court business when required. As a result, the precise number of rooms available for Crown Court use at any given time is variable.

HMCTS’s priority is to ensure all funded sitting days are fully utilised each financial year through active courtroom management. Estate capacity is not a limiting factor: last year, we sat 107,771, representing over 99% of our allocation, and we remain on track to deliver all allocated days this year.

Temporary unavailability may arise due to maintenance, but also due to overspill from other trials, alternative judicial activities (such as, box work, civil, family and tribunals hearings, or coroner’s court work), or other legitimate uses (including meetings and video-link sessions). However, these factors do not prevent the Crown Courts from sitting at their funded allocation.
