The whole home
Supply to bedrooms and living spaces, extraction from wet rooms. Heat recovery reduces energy losses. Equipment space and duct routes are needed.
ONE360 · VENTILATION
Fresh air. Thoughtfully designed.
Ventilation for your home, layout and renovation stage. A clear scope first, then a transparent estimate.
Plan my ventilationWhich solution suits your home?
Selected rooms
Heat-recovery units in external walls. Suitable for some finished homes, subject to wall openings, noise and coordinated operation.
Extract ventilation
Extraction from bathrooms and kitchen with planned air inlets and transfer paths. A local fan is not a whole-home system.
How air moves
Outside → filter → heat recovery → living spaces
Bathrooms and wet rooms → heat recovery → outside
The cooker hood is considered separately. Heat recovery does not replace heating or air conditioning.Real equipment for different needs
Examples for comparison. Selection depends on airflow, pressure, noise and available space. These are not complete installed kits.

Price on requestManufacturer detailsWhat we check in the scope
- Unit, filters and compatible controller
- Ducts, manifolds, terminals and outside connections
- Silencers, insulation and supports
- Power, condensate and penetrations
- Installation, measured airflow and balancing
Ceilings, painting, complex drilling and additional building work are quoted separately. Exact scope depends on the system.
Quiet operation and maintenance start with design
We plan filter access, acoustics and duct cleaning. Service intervals depend on the model and conditions of use.
What makes up the price
Equipment, distribution, installation and commissioning are priced separately. The preliminary result identifies sources, scope and checks still needed.
Questions to resolve before sizing the system
What information does the assessment need?
The layout, bedrooms, bathrooms, usual occupancy and stage of building work. Add whether there is space for ducts, where the unit could go and any noise or humidity issues you would like reviewed.
Do all filters provide the same protection?
No. Selection depends on the unit, the particles to be retained and operating conditions. Maintenance and replacement should follow the manufacturer's guidance. Check which particles the selected filter is designed to retain and what falls outside its scope.
Can ventilation be installed without a major renovation?
A room-based solution or routes compatible with the existing home can be considered. First check external walls, penetrations, noise, power supply and coordination between units.
Do all heat-recovery units transfer moisture?
No. It depends on the heat exchanger and equipment variant. Check the selected model’s technical documentation.
What to confirm at handover
Handover should identify operating settings, checked airflow rates, filter locations and maintenance access. Ask for an explanation of normal use, available modes and how to recognise a service alert.
Keep the exact filter reference and equipment documentation. Accessible maintenance should be part of the solution from the outset; changing a filter should not turn out to require dismantling a ceiling.
