What Our Team Has Been Working On

Our Building Services team has recently delivered a series of rapid‑response mechanical and electrical projects for Durham County Council, supporting their drive toward net‑zero carbon and improved building performance. Working across a diverse estate of schools, leisure facilities, libraries, and community buildings, we’ve managed everything from early‑stage feasibility studies to major electrical and mechanical upgrades.

Through the NEPO Mechanical and Electrical Framework, the team successfully delivered ten projects, including schemes at Consett Branch Library, Coxhoe Active Life, Copeland Road Primary School, Shotton Primary Swimming Pool, Delves Lane Primary, Villa Real School, and Rookhope Primary. These projects involved integrating renewable and energy‑efficient technologies such as solar PV, air source heat pumps, low‑energy lighting, fire alarm upgrades, and modernised heating and electrical systems which were all completed with minimal disruption to essential services.

Every commission was delivered on time and to a high standard, improving building usability, reducing energy consumption, and directly supporting the council’s sustainability objectives. If you’re excited by the opportunity to shape sustainable, impactful building services projects like these, we’d love to hear from you!
