On 29 May 2026, the Government Property Agency said fit-out works had begun at Marischal Square in Aberdeen, the site that will become the permanent headquarters of Great British Energy. The agency said the project is intended to provide a workplace that supports productivity, collaboration and different ways of working. (gov.uk) In policy terms, the announcement is administrative as much as symbolic. A headquarters fit-out is the stage at which a ministerial initiative starts to take shape as a permanent public body, with staffing, procurement and governance tied to a fixed site. (gov.uk)
Great British Energy's GOV.UK profile describes the company as a publicly owned clean energy company whose mission is to drive clean energy deployment, create jobs, strengthen energy independence and ensure taxpayers, billpayers and communities benefit from secure, home-grown energy. GOV.UK says that mission is delivered through five functions: project investment and ownership, project development, the Local Power Plan, supply chain work and Great British Nuclear. (gov.uk) That legal footing is recent. The government's factsheet on the Great British Energy Act 2025 says the Act received Royal Assent on 15 May 2025 and put the company on a statutory basis as a publicly owned and operationally independent body.

The Department for Energy Security and Net Zero announced on 24 September 2024 that Aberdeen would host Great British Energy's headquarters, with additional sites planned for Edinburgh and Glasgow. Ministers framed the choice around Aberdeen's engineering strength and its continuing role in the UK's energy sector and North Sea transition. (gov.uk) Great British Energy's own material has since set out the operational case. It says Aberdeen offers access to a large skills base and that the permanent headquarters will host the company's main corporate functions, supply chain activity and major development work, including ambitions in deep-water offshore wind.

The Marischal Square location was confirmed on 12 February 2026, when Great British Energy said the Aberdeen city-centre development would be its permanent home. The Government Property Agency later said it had secured the site through an agreement with Aberdeen City Council and would lease and manage the building during Great British Energy's occupation. (gbe.gov.uk) The decision goes beyond an address change. Great British Energy said it is currently operating from the AB1 building and expects to move into Marischal Square later in 2026, so the present fit-out marks the move from temporary accommodation to a settled headquarters designed around the organisation's longer-term functions. (gbe.gov.uk)
By the time these works started, Great British Energy had moved well beyond the concept stage. The company says it was incorporated on 10 October 2024, while the Department for Energy Security and Net Zero published the required Statement of Strategic Priorities on 16 September 2025 in accordance with section 5 of the Act. Great British Energy has since published its first Strategic Plan in response. (gbe.gov.uk) In that Strategic Plan, Great British Energy said it aims by 2030 to establish a portfolio delivering at least 15 GW of clean generation and storage through investment and ownership, support more than 1,000 local and community energy projects, and support at least 10,000 jobs. The same document says the 2025 Spending Review allocated GBE and GBE-Nuclear over £8.3 billion towards their missions. Read against that scale, a permanent Aberdeen base is part of operating capacity rather than an ancillary matter. (gbe.gov.uk)
For regional policy, the headquarters decision also carries weight. Government and company communications have repeatedly linked Aberdeen to both the UK's long-established energy industry and its next phase in offshore wind and other clean power projects, which indicates a deliberate choice to locate the company inside an existing industrial skills base rather than away from it. (gov.uk) The immediate announcement is modest in form but important in substance. The Government Property Agency's update shows that Great British Energy now has a permanent home under active development, giving public bodies, local authorities, suppliers and energy firms a clearer signal about where staffing, engagement and project decisions will increasingly be centred later in 2026.
