Reliable installation & maintenance of PIV systems.
Positive Input Ventilation (PIV) is an intelligent whole-home ventilation system designed to reduce condensation, control damp, and prevent mould growth. Installed in over one million UK homes, PIV has become one of the most trusted and widely recommended ventilation solutions available today.

Volatile Organic Compounds, including substances such as formaldehyde, can enter your home from everyday sources like paint, new furniture, and household cleaning products.
The average person breathes around 9,000 litres of indoor air every day, so poor indoor air quality (IAQ) can pose a serious risk to health. Exposure to pollutants in the home has been linked to respiratory illnesses, heart disease, and asthma, making proper ventilation essential for maintaining a healthy indoor environment.

As homes become better insulated to improve energy efficiency, they can also become more airtight. While this helps retain heat, it can also trap moisture, pollutants, and chemicals inside the home.
This build-up can lead to poor indoor air quality, with indoor air potentially containing a mixture of over 900 different chemicals, particles, and biological contaminants. Without proper ventilation, these pollutants can accumulate and may have a negative impact on health.

Everyday household activities such as cooking, cleaning, and bathing can generate up to 10 litres of moisture each day inside the home. Drying washing indoors can add a further 2.5 litres of moisture per load.
Altogether, this can mean as much as 12.5 litres of moisture being released into the air every day, which can lead to condensation, damp, and the growth of mould if the home is not properly ventilated.

Positive Input Ventilation (PIV) systems help control condensation and damp by introducing a continuous flow of fresh, filtered air into the home.
This reduces humidity levels and helps prevent condensation forming on colder surfaces such as windows, walls, and ceilings, lowering the risk of mould growth and protecting your home.

Positive Input Ventilation (PIV) systems continuously supply fresh, filtered air into your home, helping to dilute and remove indoor pollutants such as dust, allergens, and volatile organic compounds (VOCs).
This creates a healthier and more comfortable living environment, particularly for people who suffer from allergies, asthma, or other respiratory conditions.

PIV systems use low-energy fans to introduce fresh air into the home. This gentle airflow helps maintain a more stable indoor environment and can reduce the need for energy-hungry dehumidifiers or air conditioning.
By improving ventilation while using minimal power, PIV systems can help lower overall energy use and reduce household energy bills.

PIV systems promote passive ventilation by encouraging the natural movement of air through the building. This can reduce the need for mechanical ventilation systems, which can be noisy and require maintenance. Passive ventilation can also help maintain a more consistent and comfortable indoor temperature.
Modern improvements such as insulation and double glazing help homes retain heat and reduce energy loss. However, these upgrades can also make properties more airtight, which can trap moisture indoors.
Without adequate ventilation, this trapped moisture can increase humidity levels and lead to condensation, damp, and mould problems. Installing a ventilation solution such as Positive Input Ventilation (PIV) helps maintain healthy airflow, removing excess moisture while still preserving your
