The UK government took full ownership of British Steel on 16 July 2026. The Industry Minister signed the legal order, and it took effect immediately. Gov.uk

The law behind this move, called the Steel Industry (Nationalisation) Act, was given final approval — a step known as Royal Assent — on 15 July 2026, the day before the transfer happened. British Steel

British Steel's main plant is in Scunthorpe, Lincolnshire. It was bought in 2020 by a Chinese company called Jingye Group, along with other assets including a business called FN Steel. Jingye has said it wants full compensation for losing the company. On 11 June 2026, it pledged to seek "full compensation through legal means to the very end."

The government first stepped in back in April 2025, taking day-to-day control of British Steel on national security grounds. But the company still belonged to Jingye, which limited what ministers could do with it. Full nationalisation changes that. Reuters

The government set out the path in stages. In May 2026 it told Jingye it planned to pass a law to take full ownership, and published a draft bill. A ministerial written statement on or before 18 June 2026 confirmed the government's intention to nationalise British Steel, provided it was in the public interest. RFI

The government said it acted to protect a "vital national capability." Jingye had started consulting on closing the plant in March 2024, saying it was losing £700,000 a day. BBC News

Jingye is also pursuing a separate legal route. On 11 June 2026 it began a formal process under a treaty between China and the UK that protects investors in each other's countries. Think of it as a contract between two governments: if a company from one country feels it has been treated unfairly by the other, it can use the treaty to challenge that through an international panel, rather than going through UK courts.

A government spokesperson said draft rules expected in the autumn will set up a process where an independent assessor decides "what, if any, compensation is payable." That phrasing matters: the government is not saying it owes Jingye anything. BBC News

The transfer was completed the week before Andy Burnham was due to become prime minister. That adds a political layer to a situation that is already legally and diplomatically complicated. BBC News

The broader context is the strain this places on relations between London and Beijing. UK-China diplomacy is already being adjusted, and a Chinese company with state links pursuing a treaty claim against the UK government, while also making its case in public, puts that relationship under pressure from two directions at once.

The compensation setup has several parts. The Steel Industry (Nationalisation) Act provides the legal framework. The Property Transfer Regulations carried out the actual transfer. And separate rules on compensation, not yet published, will set up the independent assessor. So the ownership change is done, but the question of how much Jingye might be paid is put off — possibly beyond the next election.

Jingye's treaty process runs separately. These treaties usually require a period of negotiation before a company can take its case to a formal international panel. The government says an assessor will decide what, if anything, is owed. Jingye says it is owed everything. Those two positions do not meet in the middle.

For the Scunthorpe workforce and the businesses that supply the plant, the immediate effect is stability: the owner is now the UK government, and that is not going to change. For ministers, the legal questions are still open on two fronts — a domestic compensation process and a possible international dispute — and neither has a clear answer yet.
