More than 4,000 union members have worked on the redevelopment.

Unite general secretary Sharon Graham said: “The amazing safety record at Battersea Power Station in a sector which is the most dangerous in the UK is testament to the dedication and vision of Unite’s shop stewards, safety reps and members.

“This development stands out as an example of what can be achieved when workers have a voice. Unite will continue campaigning to ensure developers and construction firms follow the exemplary standards set at Battersea Power Station.”

Unite has worked closely with the Battersea Power Station Development Company to ensure that health and safety reps play a crucial role onsite.

Based on recent HSE data, major construction projects in the UK experience an average of approximately 2,640 non-fatal serious injuries per 100,000 workers. Under the average rate, the Battersea Power Station development should have had over 100 serious accidents instead of zero.

Unite regional officer Declan Murphy said: “I want to acknowledge the importance of the positive day-to-day working relationship with the developer who insisted on the same values from all their construction firms. Unite wants to ensure this relationship continues to complete the remaining phases of the project.”
