SJ1 Renewables’ founder, Simon England, is a time-served apprentice who started out on the shop floor producing parts and equipment for the precision aerospace industry. This provided a great grounding in engineering and, having completed a technical level apprenticeship, resulted in Simon becoming a production design engineer. Simon’s passion and overriding goal was to work his way into renewable energy technologies.
