Alistair FinchThree chemical plants operated by INEOS in Hull have ceased production as of September 2026, with company founder Sir Jim Ratcliffe warning that British industry "cannot compete" while paying gas prices twelve times higher than its US rivals. Around 1,000 workers face an uncertain future — and the legal clock governing their redundancy rights starts ticking from the moment they are sent home, not from when formal notices land.
The Gas Price Crisis Behind the Closure
UK natural gas prices have roughly doubled between July and September 2026, driven by supply disruptions following the Iran conflict and ongoing interference with oil and gas flows through the Strait of Hormuz. In his own words, Ratcliffe stated that UK gas now costs 12 times the US level and eight times that of China — rendering energy-intensive manufacturing in Britain economically impossible for companies competing in global commodity markets.
INEOS's Hull complex, spread across three sites on Humberside, produces acetic acid (used in vinegar, adhesives and pharmaceuticals), a key chemical precursor for aspirin, and industrial feedstocks used in paint, cosmetics, construction materials, detergents and clothing manufacture. According to reporting from the Financial News and LBC, two of the three plants had already stopped operations before the third was paused in the days immediately following Ratcliffe's announcement. Together, the sites employ 245 people directly and support close to 1,000 workers when contractors and supply-chain roles are included.
The phrase "production pause" is careful corporate language. Under UK employment law, however, a pause does not suspend workers' legal protections — and in some cases it accelerates them.
The energy cost pressure on UK business has compounded throughout 2026. Analysis of how the Iran conflict has affected UK energy bills shows that domestic and industrial users alike have faced a sustained squeeze, with government household support measures offering only partial relief against the underlying wholesale gas price surge.
Employment Law Kicks In Before Any Formal Notice
Under the Trade Union and Labour Relations (Consolidation) Act 1992, any employer planning to make 20 or more employees redundant at a single establishment within a 90-day period must begin collective consultation with employee representatives before any redundancy notices are issued. The legal trigger is the intention to make redundancies — not the formal announcement. For 100 or more redundancies, a minimum 45-day consultation period is mandatory. For 20 to 99 redundancies, the minimum drops to 30 days.
With 245 employees directly employed across the Hull sites, INEOS would exceed the 100-person threshold if all three plants were formally closed — triggering the full 45-day consultation requirement. The employer must also notify the Redundancy Payments Service (RPS) via the HR1 form and inform the Secretary of State before redundancy notices are served. Failure to notify is a criminal offence carrying an unlimited fine.
Critically, failure to carry out adequate collective consultation entitles every affected employee to a protective award of up to 90 days' actual gross pay. This is separate from statutory redundancy pay and can be claimed at an Employment Tribunal regardless of whether the employer subsequently enters insolvency. In administration scenarios, the National Insurance Fund covers most redundancy-related payments — but only if claims are lodged within strict deadlines.
Workers currently on temporary layoff — sent home but still technically employed — retain the right to statutory guarantee pay: currently £38 per day for up to five days in any three-month rolling period, per HMRC's 2026 rates. If the layoff extends beyond four weeks (or six weeks within any 13-week period), employees with at least one month's continuous service may trigger their own right to claim a redundancy payment by issuing written notice demanding reinstatement within seven days.
A Concrete Case: What a Nine-Year Hull Employee is Owed
Consider a 38-year-old worker who has been employed at one of the INEOS Hull sites for nine years and earns £34,000 a year (approximately £654 per week). If the production pause converts into a formal site closure and redundancy notices are issued, this is the minimum statutory position:
Statutory redundancy payment: All nine years fall within the 22–40 age bracket (1 week's pay per year of service). Weekly pay is capped at the statutory limit — £643 per week for 2025/26, revised upward each April. Minimum payout: 9 × £643 = £5,787.
Statutory notice pay: After nine years of service, this worker is entitled to nine weeks' statutory minimum notice (1 week per full year beyond the first year). At £654 gross per week, that is approximately £5,886 in notice pay.
If collective consultation is breached: A protective award of up to 90 days' actual pay could be claimed at tribunal. For this worker: 90 days ÷ 7 days × £654/week ≈ £8,411 additional entitlement.
If/then: if INEOS converts the pause to a formal closure without adequate collective consultation, this hypothetical employee could be owed statutory redundancy pay + notice pay + protective award — a combined floor of approximately £20,000 before tax, before any enhanced contractual terms apply.
That last point matters. Many employees at large chemical companies hold collective agreements negotiated by Unite the Union that provide enhanced redundancy pay — commonly two or three times the statutory amount. For someone on nine years' service, a two-times contractual enhancement would push the redundancy component alone above £11,500. Employers are not obligated to volunteer this information; workers must check their employment contracts or ask their union representative directly.
What Workers and Families in Hull Should Do Now
Verify your contractual terms immediately. Your contract of employment or the collective agreement applicable to your workplace sets the baseline for any negotiation. Enhanced terms are not uncommon in the chemicals sector — and they are legally binding even if the company is struggling financially.
Engage your union early. All three Hull sites fall under Unite the Union coverage. Unite has the right to collective consultation, access to financial information about the business decision, and the ability to challenge the adequacy of any consultation process at the Central Arbitration Committee (CAC). Union reps can also negotiate the selection criteria used for redundancy, preventing arbitrary or discriminatory choices.
Record the precise dates of any communications. The date a worker is told not to report for work, or receives written confirmation that their site is paused, is legally significant. Consultation obligations are triggered by the moment a decision to consider redundancies is made — employers sometimes argue that point is later than workers believe. Written records of all management communications strengthen any subsequent tribunal claim.
Do not wait for a formal redundancy notice to seek advice. An employment solicitor can assess whether the HR1 notification has been filed correctly with the Redundancy Payments Service, whether the 45-day consultation clock is running, and whether any tactical steps — such as tendering a constructive dismissal claim if the layoff terms breach contract — are available. The UK government's official guidance on redundancy rights and the statutory redundancy pay calculator provides a useful starting point, but individual circumstances often produce outcomes that diverge significantly from the statutory floor.
Many employment solicitors offer a free first consultation and will take strong protective award or redundancy entitlement cases on a no-win, no-fee basis. If you work at one of the INEOS Hull sites — or in a supply-chain role dependent on them — speaking to an employment law expert via Expert Zoom can clarify your rights, the timeline you are operating under, and the potential value of any claim before deadlines run out.
