Ineos Mothballed Three Hull Chemical Plants Over Gas Prices. 245 Jobs Are Being Kept On, for Now.
Estimated reading time: 5 minutes
In short. Ineos announced on 22 September 2026 that it is mothballing, not permanently closing, all three acetyls production units at its Saltend Chemicals Park site in Hull, citing UK gas prices it says are twelve times the US level and eight times China's [1]. The 245 staff directly employed at the site are being retained while the company tries to secure cheaper gas; nobody has lost their job yet [2]. The ledger logs a loss of 245, graded ANNOUNCED, status at-risk, region Yorkshire and the Humber, ai_cited: not-raised.
The announcement. Ineos said on 22 September 2026 that it was idling all three of its acetyls units at Saltend, which make acetic acid, acetic anhydride and ethyl acetate for use in medicines, clothing, cosmetics, detergents, construction materials and military explosives [1]. The company's own framing is specific: these plants are "mothballed until further notice," not shut, and are, in its account, among the most efficient of their kind anywhere in the world [1]. Ineos founder Sir Jim Ratcliffe put the cause in one sentence: "gas prices now 12 times the level in the US and 8 times that of China, we just cannot compete" [2].
Saltend directly employs 245 people, and all of them are being kept on while the company tries to find a way to run the plants economically again [2]. Ineos itself warns that a permanent closure, which it has not announced, could put close to 4,000 jobs at risk indirectly across the wider Humber region through its supply chain [2]; that figure describes an indirect, regional exposure, not a headcount this ledger can attach to one employer, so it is reported here but not logged as a row of its own.
Beverley and Holderness MP Graham Stuart sought an urgent meeting with ministers after the announcement, and as of 6 October 2026 trade press was reporting continued government silence a week after a cross-party plea to intervene [2].
How the ledger logs it
A loss of 245, graded ANNOUNCED, status at-risk, not departed. This is the clearest possible case of this ledger's first rule: a mothballing is not a closure, and 245 people being kept on the payroll while a company negotiates gas prices is not the same thing as 245 jobs gone. The figure comes from Ineos's own statement and corroborating trade press, not from a filing, so it is ANNOUNCED. Region is Yorkshire and the Humber, where Saltend sits on the north bank of the Humber estuary near Hull. AI is not mentioned anywhere in any account of this decision; the stated cause, repeated by Ineos in every source checked, is the gap between UK and international gas prices, nothing else.
What Ineos says caused it
The company's account is narrow and consistent: energy costs, not demand, not automation, not strategy. Every figure Ineos has put on the price gap points the same way, UK gas far more expensive than the US or China, and the company has not raised cost per employee, changing demand for its products, or new technology as a factor in the decision [1] [2]. That narrowness is itself worth noting: a company mothballing plants it calls among the world's most efficient is making a point about the price of the input, not the output, and the absence of any other stated cause makes gas price the whole of Ineos's case rather than one factor among several.
What happens next in this ledger
Three things to watch: whether government engages with Stuart's request for a meeting, whether gas prices move enough for Ineos to restart the units, and whether "mothballed until further notice" becomes a timetabled closure, which would move this row from at-risk to departed and turn the 4,000-job regional exposure figure from a warning into a live story of its own. A pause dressed as a pause should be checked back on; this ledger will.
