Sustainable Engineering Solutions in Leeds
Established in 2001 by Mike Silcock and Bill Leedham, our company has grown into a leading building services engineering consultancy with a focus on mechanical, electrical, and public health system design. We became a limited company in 2010 to ensure sustained growth and client security, operating from our UK headquarters with international reach across Europe, Africa, the Middle East, Asia, and Australia. Our expertise spans science and technology, healthcare, education, residential, and commercial sectors, supported by a strategic partnership with zero energy design (zed.) for net-zero-carbon consultancy. We employ over 100 professionals, all working under one roof to deliver tailored, sustainable solutions through innovative digital engineering and traditional design practices.Our commitment to BIM methodologies and ISO 19650 standards ensures efficient project delivery, while our in-house energy experts enable holistic sustainability assessments. Recognised with industry awards, we align our services with client business goals and global sustainability targets, including the UN Sustainable Development Goals and Science Based Targets initiative. Our team of problem-solvers and creators continues to drive innovation, ensuring we remain at the forefront of low-carbon building design and engineering excellence.

Services
Mechanical and electrical design
We provide comprehensive mechanical and electrical design services for new builds and retrofits, focusing on low-carbon solutions. Our engineers deliver scalable designs from concept to construction, incorporating 3D coordination and clash detection. With expertise in laboratories, healthcare facilities, and heritage buildings, we ensure systems meet operational efficiency and sustainability goals.
Building Information Modelling
Our BIM services utilise Revit and Navisworks for 3D design, document standardisation, and automation. We comply with ISO 19650 standards, offering COBie schedules and IFC file integration. This approach enhances collaboration, reduces design risks, and supports efficient project delivery for large-scale developments.
Net-zero-carbon design
We specialise in net-zero-carbon strategies through fabric-first design, thermal modelling, and renewable energy integration. Our team provides BREEAM assessments, life cycle carbon analysis, and climate resilience planning to help clients meet Paris Agreement targets and regulatory requirements.
Energy assessments
We conduct energy performance certifications (EPCs), SAP calculations, and TM54 thermal modelling. Our assessments guide material choices, system efficiencies, and operational strategies to reduce both embodied and operational carbon in buildings.
Heritage sector solutions
We adapt traditional engineering principles for heritage sites, balancing modern efficiency with preservation needs. Our solutions maintain architectural integrity while integrating sustainable systems for listed buildings and conservation areas.
