A typical loft-mounted PIV system filters incoming air and feeds it gently into the home through a ceiling diffuser. That airflow helps dilute moisture-laden indoor air. The property needs suitable ventilation routes for displaced air to leave.
PIV units are designed for continuous background ventilation. Fan speeds are selected for the property; the model, setting and installation influence noise and power use. We can explain the proposed unit and its controls before fitting.
A loft system needs a suitable loft, safe access and an appropriate diffuser position. A flat or home without a loft needs a different assessment and may require another ventilation solution. PIV is an option to assess, rather than a fit for every home.
PIV does not repair leaking gutters, roof defects or ground-moisture problems. We look at the cause of damp first, along with existing extraction and air paths. Kitchens and bathrooms still need effective ventilation for the moisture they produce.
A loft-mounted unit draws air through its filters.
A discreet ceiling diffuser introduces a steady airflow.
The airflow dilutes indoor moisture as displaced air leaves through suitable ventilation routes.
Suitability comes first. PIV can help with condensation; leaks and other sources of damp need their own repairs.
Tell us which rooms are affected. Loft ventilation, access, ceiling position and air routes through the home all need checking. Existing extraction, flues and fire safety also matter. A loft unit should be chosen after the property has been assessed.
Agree the unit, diffuser position, electrical connection and any making good before booking. Ask who will carry out the electrical work and what is included in the price; wiring needs a suitably qualified person.
Compare the proposed model’s fan and heater consumption, filter care and warranty terms. At handover, confirm the settings, filter care and any follow-up questions. Keep the operating instructions for reference. Filter maintenance varies by unit and the conditions around your home.

The unit, any heater, loft access, diffuser location, electrical work and making good affect the price. Ask us for a quotation for your property and check what is included, rather than comparing the price of a fan alone.
Where condensation contributes to mould, improving ventilation can be part of controlling the conditions that allow it to return. Existing mould also needs appropriate treatment, and any leaks or building defects must be addressed. No ventilation unit can guarantee a mould-free home.
Running cost depends on the chosen unit, fan setting, electricity tariff and whether it has a heater. Heater use can change consumption substantially. We can discuss the proposed model and manufacturer information with you; there is no single cost that applies to every installation.
Yes. Follow the manufacturer’s instructions for the particular unit, including filter checks or replacement and keeping the diffuser clear. The schedule depends on the model and conditions, so keep the instructions supplied with your installation.
Age alone does not decide suitability. Layout, moisture sources, existing ventilation and installation space matter. Homes without a suitable loft may need an alternative system. Ask us to assess the property before choosing a unit.
No. PIV supplies air to the home; an extractor removes air, usually from a room such as a bathroom or kitchen. They perform different jobs and need to be considered together as part of the home’s ventilation.
