Professional HVAC Design Services Across the UK
Our HVAC design services provide heating, ventilation and air conditioning designs for homes, commercial buildings and mixed-use schemes. We work with builders, developers, architects and MEP contractors to design comfortable, energy-efficient systems that are practical to install.
Each design package includes calculations, layouts and equipment schedules, coordinated with the other building services to reduce clashes on site.
What an HVAC Design Package Includes
- Heating and cooling calculations: heat loss and heat gain for each room or zone.
- Ventilation layouts: extract, supply and mechanical ventilation systems.
- Ductwork plans: duct routes, sizes, grilles and diffusers.
- Heating layouts: radiators, underfloor heating and pipework routes.
- Equipment schedules: boilers, heat pumps, air handling and cooling units.
- Installation drawings: technical drawings for the installer.
Heating, Ventilation and Air Conditioning Design
- Heating design: radiator and underfloor heating systems, with boilers or heat pumps.
- Ventilation design: extract fans, MVHR and mechanical ventilation systems.
- Air conditioning design: split systems, VRF systems and cooling for commercial spaces.
- Ductwork design: routes and sizes coordinated with the building structure.
Designed With UK Building Regulations in Mind
Our designs take into account the ventilation and energy efficiency requirements of the Building Regulations, including Part F (ventilation) and Part L (conservation of fuel and power), where they apply to your project. The design information supports your Building Control submission.
What We Need to Start
- Architectural plans, elevations and sections, in PDF or CAD format
- Room uses and occupancy, where known
- Wall, floor, roof and window build-ups or U-values
- Your preferred heating or cooling system, if chosen
- Your programme or deadline
HVAC Design for Different Types of Project
- Homes and flats: heating, ventilation and heat pump systems.
- Offices: heating, cooling and fresh air ventilation.
- Retail units: heating and cooling for shops and showrooms.
- Schools: ventilation and heating for classrooms and halls.
- Healthcare: heating and ventilation for clinics and care facilities.
How We Prepare an HVAC Design
- Review the architectural drawings and project brief.
- Carry out heat loss and heat gain calculations.
- Select and size the heating, ventilation and cooling systems.
- Prepare layouts, ductwork plans and equipment schedules.
- Coordinate with other services, make agreed changes and issue the final design.
Coordinated With Other Building Services
HVAC systems share ceiling voids, risers and plant rooms with electrical, plumbing and fire protection services. We coordinate the HVAC design with these services, so ductwork and pipework fit the space and clashes are found before work starts. See our MEP coordination drawings.
HVAC Terms Explained
- HVAC: heating, ventilation and air conditioning.
- Heat loss calculation: working out how much heat a room loses, to size the heating.
- Heat gain: the heat a room gains from sun, people and equipment, used to size cooling.
- MVHR: mechanical ventilation with heat recovery.
- VRF: variable refrigerant flow, an air conditioning system for multiple rooms.
- U-value: a measure of how much heat passes through a wall, floor, roof or window.
What You Receive
- Heating and cooling calculations
- Ventilation and ductwork layouts
- Heating layouts and equipment schedules
- PDF drawings and editable CAD files
- Updated drawings after agreed changes
Frequently Asked Questions About HVAC Design
What is included in an HVAC design package?
A package typically includes ventilation layouts, heating and cooling calculations, ductwork plans, equipment schedules and installation drawings.
Do you provide HVAC designs for residential and commercial projects?
Yes. We design for homes, flats, offices, shops, schools, healthcare facilities and other commercial developments.
Can your HVAC designs be coordinated with other building services?
Yes. We coordinate the designs with electrical, plumbing and fire protection services to reduce clashes on site.
Do you design heat pump systems?
Yes. We design heating systems with air source and ground source heat pumps, including heat loss calculations to size the system.
Do you design ventilation for Building Regulations?
Our ventilation designs take Part F requirements into account and support your Building Control submission.
Can you also estimate the cost of the HVAC installation?
Yes. We can prepare a line-by-line cost estimate from the same design.
