# Great British Energy Act 2025 receives royal assent

Date: 2025

## The fact

On 15 May 2025 the Great British Energy Act 2025 received royal assent. The Act lets the Secretary of State designate a Crown-owned company to facilitate, encourage, and participate in clean-energy production, storage, and supply.

## Context

[Ed Miliband](/people/energy-ed-miliband) introduced the Bill in July 2024. It completed Commons and Lords stages and received legislative consent from devolved governments. Starmer had made public ownership of a clean-power vehicle a manifesto item after dropping the larger £28 billion pledge. GB Energy still needs a statement of strategic priorities, capital, and private co-investment. Construction lag is years. NESO still plans the system. The Act is not a retail-price freeze.

The February 2024 pledge withdrawal is a different date. Clean Power 2030 plans are neighbouring. Do not treat the Act as a completed decarbonization of the grid.

The Prime Minister of the United Kingdom is First Lord of the Treasury and chairs Cabinet. He does not enact statutes alone. Parliament enacts; courts review; the Home Office, DWP, HMT, MoJ, DESNZ and NESO implement. After 20 July 2026 he is a backbench MP for Holborn and St Pancras, not the author of [Andy Burnham](/people/andy-burnham)’s instruments. Office-holding is not authorship of every later welfare series. Allegation is not a completed judgment.

## Evidence and sources

16) (https://www.legislation.gov.uk/ukpga/2025/16/contents; legislation.gov.uk).

legislation.gov.uk carries the official instrument or communique. GOV.UK records the same dated act independently.

## Significance

The path is renewable buildout and energy security: a completed public-ownership vehicle can crowd-in clean-power projects. It does not by itself cut bills that afternoon.

## What is established and what is not

Established: royal assent on 15 May 2025 for a statute creating the designation framework for Great British Energy.

Not established: a unique 2025 household-bill coefficient, or that private developers ceased to exist.

What would change the picture: a contradictory original with a different date or name, a later repeal, a court that vacated the instrument, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Miliband carried the Bill. Parliament enacted. The company still has to invest.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Great British Energy Act 2025 receives royal assent, not a later speech about Great British Energy Act 2025 receives royal assent.

Co-authors and later implementers named in Context remain on the file. Great British Energy Act 2025 receives royal assent on 2025-05-15 is not a licence to treat every later legislation.gov.uk communique as this same act. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. This dossier refuses to average Great British Energy Act 2025 receives royal assent into a personality. The contribution described on this Person row is limited to He made GB Energy a manifesto and King’s Speech item. Miliband carried the Bill. Parliament enacted. The company still has to invest. That limit is the alternative to treating office-holding as authorship of every later series.
