Mechanical Design
Mechanical design services play a central role in modern building projects, ensuring efficient heating, cooling, ventilation, and energy performance. At Focus 360 Energy, we provide professional mechanical design that supports both domestic and commercial developments, aligning with Building Regulations, sustainability goals, and wider project requirements. Our services help architects, developers, and contractors deliver buildings that are safe, comfortable, and energy-efficient by specifying the optimal HVAC and water systems.
What are Mechanical Design Services?
Mechanical design services encompass the comprehensive planning and detailed specification of a building’s functional internal systems. This primarily includes Heating, Ventilation, and Air Conditioning (HVAC) systems, along with the design for hot and cold water supply, drainage, and integrated energy solutions. Our mechanical engineers provide tailored, calculated solutions to match the project scale, whether it’s a single dwelling, large commercial development, or complex mixed-use scheme, ensuring all systems meet occupant needs and regulatory requirements like Part L and Part O.
What Does the Mechanical Design Service Involve?
Mechanical design services encompass the planning and specification of heating, ventilation, and air conditioning (HVAC) systems, along with hot and cold water supply, drainage, and energy systems. Our mechanical engineers provide tailored solutions to match project scale, whether it’s a single dwelling, large commercial development, or complex mixed-use scheme.
Key elements include:
- Heating and cooling load calculations
- Ventilation and indoor air quality planning
- Hot and cold water system design
- Energy efficiency and renewable integration
- Compliance with Part L, Part O, and other relevant Building Regulations
Why Mechanical Design Matters
Undertaking detailed mechanical design services at the appropriate stage is vital for de-risking construction and guaranteeing long-term building performance. Early, coordinated design detects potential conflicts and interferences (e.g., clashes with structural elements) before they become costly site issues. Furthermore, a professional mechanical design ensures seamless compliance with mandatory industry codes and Building Regulations, validating the project’s energy performance and securing approvals, ultimately delivering a building that is efficient, comfortable, and safe for its occupants.
How Our Accredited Assessors Support You
Our team comprises professional mechanical engineers and accredited energy specialists. Crucially, we work with the outputs of our in-house SAP, SBEM, and Overheating Calculations. This integration ensures your mechanical specifications (plant efficiency, fabric interface, ventilation rates) are perfectly aligned with the project’s compliance goals from the outset. We don’t just specify equipment; we ensure the mechanical system delivers the theoretical performance predicted by the energy models, providing a coordinated, unified M&E solution that is both compliant and constructible.

Frequently Asked Questions
Mechanical design services involve the detailed specification of heating, cooling, ventilation (HVAC), and water systems to ensure buildings are safe, efficient, and compliant with regulations.
Yes, even small residential projects benefit, as it ensures efficient heating, sufficient ventilation, and guarantees compliance with Part O (overheating) and Part L (energy).
The service is typically completed within 1–2 weeks, though this depends on the complexity and scale of the project.
Yes, the system specifications and associated calculations are often essential evidence required by Building Control, particularly for complex HVAC or water systems.
Absolutely. Focus 360 Energy specialises in providing both mechanical and electrical design services to ensure a fully coordinated M&E solution.
The cost of the service depends entirely on project size and scope. Focus 360 Energy provides clear, fixed-fee quotes based on your specific requirements.
Yes, our design scope includes the optimal integration and sizing of renewables such as heat pumps, solar thermal, and other low-carbon technologies.
Mechanical design should be undertaken at RIBA Stages 3–4 (Developed and Technical Design) to ensure systems are integrated and coordinated before construction begins.
The main benefit is the early detection of clashes between mechanical systems, electrical infrastructure, and structural elements, preventing costly re-work on site.
Mechanical design produces detailed drawings and specifications for contractors; an M&E report is usually a high-level summary or feasibility study.
Yes, Focus 360 Energy offers mechanical design services for projects across the UK.
Focus 360 Energy combines technical expertise, sustainability focus, and a joined-up compliance approach to deliver reliable mechanical design services.
