There is set to be disruption at Sellafield, as Unite members working for PX Limited, the firm supplying the steam and power to the Cumbria nuclear site, are walking out in a dispute over pay.

Almost 40 workers will take industrial action from 7am on 19 August to 7am on 20 August after turning down two unsatisfactory pay offers from the employer - with the final being 3.5 per cent to 5 per cent depending on a set of criteria.

Members at PX Limited who will be on strike include operators, team leaders, planners and buyers. Workers are also currently undertaking an overtime ban.

The workers taking part in the dispute play a vital role at Sellafield as the plant can't do some of its nuclear operations without the power they supply to it. Unite members believe their pay should reflect the fact they are an intrinsic part of processes at Sellafield.

PX Limited is a highly profitable company. According to its latest financial report submitted in 2024, it has a turnover of £77m, making a gross profit of £15m and compared with the previous year it had a turnover increase of 61 per cent.

Unite general secretary Sharon Graham said: "PX Limited can clearly afford to pay our members for the vital work they do but is choosing to put profits over people. This dispute is completely caused by the employer's greed.

"Unite will always back our members every step of the way in any dispute and this is no exception. The workers at PX Limited have our full support."

The workers at PX Limited provide critical process steam and electricity to Sellafield. Strike action would cause disruption to any facilities that rely on this.

Unite regional officer Ryan Armstrong said: "This dispute involves the whole spectrum of the workforce so any industrial action would be very disruptive. However PX Limited could stop this if they come to the table with a deal appropriate for our members."
