The Workers Rights 
Three of its chemical plants at Saltend, near Hull, are to be mothballed, and INEOS Hull jobs are under real threat after INEOS Acetyls said it was going to suspend operations at all three. The decision, which will come into effect from the end of September 2026, will threaten nearly 4,000 jobs and apprenticeships, not just at the plant, but throughout the industrial network it relies on. Workers, families and businesses in East Yorkshire are now in very real uncertainty as no restart date has been confirmed.

| Primary reason given | European gas prices are compared to US/China production prices. |
| Restart timeline | Until further notice, no date set. |
Why Are INEOS Hull Jobs Under Threat?
The real issue is the price of energy. The natural gas required for a chemical plant, such as Saltend, is very extensive, both as fuel and a raw material. Energy costs are much cheaper in the United States and China than they are in the UK, making it much more costly to make acetyls in the UK than elsewhere. If chemicals can be sourced abroad, at a lower price, then it no longer makes financial sense to produce them locally.
This isn’t a demand problem. This is a cost issue: the issue that has been mounting for years and now has come to a critical level.
The Saltend plants make acetyls, which have a range of uses in the pharmaceutical, textile, cosmetic, cleaning, construction and food industries. Saltend was the last place in Europe where world-scale acetyls plants were located. That’s what makes this more than just a local story.
What Does “Mothballing” Actually Mean for Hull Workers?
Mothballing doesn’t mean that it’s closed permanently; it’s just that it’s not business as usual.
Mothballing means suspending the production of a plant, but maintaining it in a preserved condition for possible future resumption of production. Until further notice, there is no certainty that it will be brought back online.
This is a spectrum of risk for industrial employment in Hull:
- Immediate uncertainty in the minds of direct INEOS employees over roles, some of whom have been left to carry out safe shutdown and maintenance.
- If the site service worker is a contractor, they might be losing their job in a few days.
- But young people’s apprenticeship opportunities in the chemical industry, which have long served as a major route into the sector in this area, are threatened as there has been no sign of plans to continue apprenticeships.
- If the demand for their salted goods remains the same, Saltend cluster businesses are affected by knock-on effects, as other businesses in the cluster, such as logistics operators or maintenance providers, are affected.
The longer that the shutdown lasts, the more difficult a restart will be. Professional workers move on to other jobs. Customers turn to other overseas suppliers and will not return. Equipment deteriorates. What starts as temporary can turn out to be a permanent thing.
Comparison: Mothballing vs. Permanent Closure
| Factor | Mothballing | Permanent Closure |
| Production | Stopped | Stopped |
| Site preserved? | Yes | Not necessarily |
| Restart possible? | Yes, if conditions get better | No |
| Jobs kept on site? | Some (maintenance/safety) | Minimal |
| Apprenticeships | Paused/uncertain | Ended |
| Customer relationships | At risk of drifting | Lost |
| Supply chain impact | Significant | Severe |
What Happens to the 4,000 Supported Jobs?
4,000 is not just the number of INEOS employees directly. It represents the entire ‘ecosystem’ of the contractors, suppliers, hauliers, specialists and companies throughout Hull and East Yorkshire that depend on Saltend having a life.
There is a multiplier effect for the loss of a site this size on the employment of Hull generally. The fewer the number of changes at Saltend, the less work for local transport companies and the fewer orders for local suppliers, and the less footfall for local businesses.
The situation for Saltend apprenticeships is of particular concern. Many young people had envisioned a career in the chemical and process industries that is shaped by apprenticeships, and losing them in the middle will have a negative impact on their career trajectory — and even the cancellation of new apprenticeship programmes.
What Would It Take to Restart?
The short-term decline in the price of gas is likely not sufficient. However, INEOS would need to have faith that they could maintain their margins in future, in order to re-open the plants. Possible routes include:
- High-quality long-term energy contracts at competitive prices.
- Relief package for energy-intensive industries from the government.
- Use trade measures that consider the carbon intensity of imported chemicals.
- The rising prices of acetyl in the world market are expected to persist.
But none of these easily implemented changes — the “until further notice” is important because of the Hull jobs that are threatened now.
FAQs: INEOS Hull Jobs and Saltend Mothballing
Q: Do INEOS Hull workers have their jobs cut now?
Not automatically. The mothballing process involves staff safely shutting down and preserving the facility. However, finding a job in the longer term will require it to become a possibility to restart. Staff are to be aware of formal consultation procedures.
Q: Are there any plans to continue INEOS apprenticeships at Saltend?
There is no definite plan in place for continuation. Uncertainties for current apprentices and those who were anticipating taking on programmes are high. The person concerned is advised to discuss their situation with their training provider and local skills authority for possible resolution.
Q: Will the Saltend plant be permanently shut down?
Mothballing does not mean closure, but is an option to restart. But the longer it sits idle, the more expensive and difficult it will be to get it back into production.
Q: What support is available for Hull workers affected?
Redundancy payments, retraining schemes and local employment schemes should be explored for workers as a potential eligibility. There are some resources available to people in East Yorkshire who are at risk of losing their job in the manufacturing sector, from their local authority and from the Department for Work and Pensions.
Q: Can the Government rescue INEOS Hull jobs?
Potentially — but the window is small. Supporting when equipment deteriorates, workers have left the scene, and contracts have gone to overseas locations is not as effective. Policy response must be swift and incorporate a feasible, measurable restart condition.
