Set for completion in 2026, the 7,459 m² facility is being built to add to existing manufacturing capacity to meet growing global demand for the company’s high-reliability and industrial connectors.
The state-of-the-art electronics manufacturing facility incorporates multiple design initiatives that minimise the environmental impact of Harwin's operations including the use of rooftop solar, with 388 high-efficiency solar panels generating a forecast 244,000 kWh annually. This will reduce the sites CO₂ emissions by approximately 32 tons per year - equivalent to planting 1,471 trees.
Minimising land usage and the building's effect on the local environment were also key considerations during the planning phase, with the facility using a novel multi-level design that span four floors.
The building also meets stringent BREEAM sustainability standards. BREEAM is the world’s leading science-based suite of validation and certification systems for sustainable buildings and has been sought as part of Harwin’s commitment to environmentally responsible manufacturing.
According to Harwin, steps have also been made to reduce the impact of travelling to work. This includes a significantly higher than average bike to car parking ratio, with more than a third of all parking spaces dedicated to bikes. Electric vehicle charging points will also be available, encouraging more eco-friendly travel choices.
Following its completion, this manufacturing site will bolster Harwin’s ability to serve key markets, including aerospace, defence, industrial automation, and advanced electronics.
The new facility will double manufacturing capacity in Portsmouth, and the expansion will allow Harwin to continue delivering high-quality interconnect solutions while ensuring supply chain resilience for its customers worldwide.
“The construction of this new facility is a major milestone for Harwin, strengthening our ability to support innovation and meet growing customer demands,” said Jon Churchill, Harwin's Operations Director at Harwin. “By integrating sustainability into our design and operations, we are not only expanding our manufacturing capabilities but also setting a new benchmark for responsible industrial development in the UK.”
